The View From Austin Stephen R. Matteson, D.D.S., FICD, Editor
The American Way at the TDA “Microphone 2 is reserved for speakers against a resolution under consideration. Microphone # 1 is reserved for speakers who support the resolution. Microphone 3 is provided for delegates to raise points of order,” Dr. Glen Hall, the TDA Speaker of the House, announced at the Texas Dental Association House of Delegates 2011 annual meeting earlier last month.
The atmosphere in the large room resembled a political convention with vertical signs in the corners of the room designating the four districts of the TDA. The delegates grasped green voting cards in ready for upcoming votes. Officers of the organization were seated at a raised table facing the assembled delegations and the speaker of the house sat at a raised chair behind a podium prepared to conduct the meeting. Members of the TDA Board of Directors were seated along the first row. Rules of order were close by for referral when conduct of the meeting was in question. Placards stating names and the delegate’s district or officers of the TDA were present on the table at each seat. A junior ROTC color guard presented the colors of the USA and Texas. The young women in the color guard performed the ceremony in military precision. Many delegates opened their computers to access the House Book containing the many resolutions to come to the group for consideration. The TDA Awards Committee gathered at the front of the room to present the various service and other awards of the Association. Committee members presented the awardees with their plaques as they walked across a platform. Dr. Jerry Long’s 15th ADA District Trustee’s report was well received.

The 141st Annual Session of the Texas Dental Association
Dr. Ronald L. Rhea, President President’s Address to the Texas Dental Association House of Delegates, May 5, 2011 Mr. Speaker, TDA Board of Directors, House of Delegates, and distinguished guests. Congratulations! I am here with you today to celebrate! Dentistry and the Texas Dental Association are alive and well in Texas! This would not be the case without your wisdom and leadership. The decisions that you have made in this House, the selection of members you have sent to Austin and Chicago, and the activities of the local dental societies which you represent are in large part responsible for the good health of the profession, particularly in Texas, and the dental health of the citizens of Texas. The health of dentistry in Texas is no accident. Hard battles have been fought this year. You can be proud of your members who have lead these battles in Texas and at the national level. 512
Texas Dental Journal l www.tda.org l June 2011
Forces exist which would degrade dentistry into a retail trade with marketing, not professionalism, being the driving force.
There are states in our nation where the profession of dentistry as we know it is not secure. Forces exist which would degrade dentistry into a retail trade with marketing, not professionalism, being the driving force. Caveat emptor — “let the buyer beware” — would replace ethics as the core principle, and educational expedience and profitability would guide our dental schools. Two years ago, almost immediately after being installed, your then president Dr. Matt Roberts of Crockett, TDA executive director Ms. Mary Kay Linn, TDA Council on Legislative and Regulatory Affairs chair Dr. Rick Black of El Paso, and I flew to Washington, D.C., for the American Dental Association (ADA) Washington Leadership Conference. Dentists from across the country gather at this annual conference to learn about state and national issues affecting dentistry and to discuss these issues with their senators and representatives. Time is also available for state leaders to discuss with each other the status of dental practice in their districts. I often sat aghast at the tales of woe. It was the first time ever that I gave an embarrassed Rick Black a hug and thanks for his leadership of CLRA in preserving dentistry in Texas. In his final address last year, Dr. Roberts spoke of the formation of the Austin Group.
TDA president Dr. Ronald L. Rhea speaks to the 2011 TDA House of Delegates in San Antonio.
Dismayed by developments coming from the ADA which seemed to be promoting mid-level providers, the TDA Board of Directors approved funding for a conference of like-minded states to meet in Austin. Lead by Dr. Black and Dr. Roberts, this coalition, which became known as the Austin Group, orchestrated strategies to reinforce ADA policy against those other than a dentist performing irreversible surgical procedures. As we approached the ADA Annual Session last year, a task force from the ADA Council on Dental Practice (CDP) presented four resolutions which would have changed the fundamental policy of the ADA by allowing delegation of irreversible surgical procedures to someone other than a dentist. At the end of June, Dr. Craig Texas Dental Journal l www.tda.org l June 2011

Dr. Ronald L. Rhea, President
Armstrong of Houston, Texas’s member on this CDP taskforce, with help from the TDA staff, wrote the dissenting minority report urging defeat of these resolutions by the ADA House of Delegates. With strong input from your representative Dr. Jim Condrey of Houston, the ADA Council on Governmental Affairs recommended that the ADA House of Delegates defeat these resolutions. It was the first time that one ADA council recommended defeat of another council’s resolutions. Next, Dr. Jerry Long, the 15th District Trustee, joined by other trustees, led the defeat of these resolutions by the Board of Trustees. It was a close vote. Finally, at the ADA annual session in October in Orlando, these leaders, supported by the members of the Austin Group, orchestrated the defeat of the resolutions on the House floor, and strongly reinforced ADA policy on anyone but a dentist performing irreversible surgical procedures.
(L-R) ADA 15th District Trustee Dr. S. Jerry Long greets TDA president Dr. Ronald L. Rhea, both of Houston, at the 2011 TDA House of Delegates.
Is this fight over? It certainly is not. As you all know, the ADA does not decide who practices dentistry in Texas or any other state. In Texas, the state legislature writes and modifies the dental practice act, which is codified and enforced by the Texas State Board of Dental Examiners. Those who would allow midlevel providers to practice dentistry in Texas are not coming to you, the governing body of the TDA for permission. They will approach the legislature directly, very likely without even consulting you. Indeed this year, one foundation allocated $16 million dollars to lobby for Dental Health Aide Therapists (DHATs) in five states. Texas is not one of those states, but our nearest neighbor New Mexico is. It is imperative that you maintain and improve your relationships with your legislators. We cannot compete on a dollarfor-dollar basis with these wealthy foundations, but we can compete in the personal relationships we have with our legislators.
514
Texas Dental Journal l www.tda.org l June 2011
Dr. Ronald L. Rhea, President
Unfailingly, as I mention becoming involved in the political process, some well-meaning dentist will say, “Oh, I don’t want anything to do with politics, it is such dirty business.” That is certainly a common opinion. In January at the ADA Lobbying Conference in Tucson, Arizona, the leaders from the 50 state dental associations received a T-shirt to commemorate the meeting. The quote on the back by Ronald Reagan says it all, “It has been said that politics is the second oldest profession. I have learned that it bears a striking resemblance to the first.” All Texas dentists are political animals. You are allowed to practice dentistry in Texas not because you graduated from one of our fine dental schools, but because the state of Texas allows you to practice dentistry. The state can also tell you what you can and cannot do as a dentist. The state might also allow others to practice dentistry. Whether you are active or passive in the political process determines the future of dentistry in Texas. At this time, the 82nd Session of the Texas legislature is approaching the end of its 140day session. The dominant themes in Austin have been the
budget shortfall and mandatory redistricting. As we strive not to get crushed by these two giants lumbering in Austin, I am reminded of an old Godzilla meets King Kong movie! Tremendous amounts of time have been expended by your Board, CLRA, legislative staff, and legislative consultants. The battle still rages. I will leave it for Dr. Black to give you the blow by blow and to speculate on the outcome. Much will not get done during this session. I am asking for your direction and approval to take the fight to the next session for several initiatives. •
•
•
Expand the enforcement powers of the Texas State Board of Dental Examiners to include those who practice dentistry without a license. This would also include the bleaching of teeth by those other than a licensed Texas dentist and his or her staff. Because of the likely increased enforcement cost, this may require a fiscal note. Require mandatory dental examinations for schoolaged children. Write into law that no member of the Texas State Board of Dental Examiners may testify as an expert
•
witness in a dental malpractice case in Texas. Identify a new Expanded Function Dental Assistant based on the U.S. Army model to be allowed for those dentists practicing in federally defined underserved areas. This should be sent to the Council on Dental Education Trade and Ancillaries for study with recommendations to the Board and next year’s House for final approval.
During this House of Delegates, we will consider a number of resolutions. I would like to speak for a moment about your deliberations. Each of you certainly must have noticed the trend towards decentralization of authority in the governance of the Texas Dental Association. Why have the president make a decision if the three presidents can get together? Why have the Executive Committee make a decision if the whole Board of Directors can be convened to deliberate? Why have the Board of Directors make a decision if the House of Delegates can make the call? And, at the extreme, why have the House of Delegates decide if the whole membership can be polled?

Dr. Ronald L. Rhea, President
We all believe in the democratic process. Each of us wants to have a say in processes that affect our lives and livelihood. However, as the group size grows, the idea of representative democracy becomes important and may indeed give better decisions for two reasons: •
•
Elected leaders, like you, are those who have said they are willing to allocate the time and energy to thoroughly study the issues. The smaller the group, the more quickly a decision can be made when it is needed.
In one of my early articles, I expressed that I never cease to be amazed at the wisdom of the decisions made by this House. An issue provided to this House for consideration may seem at first to be irrevocably contentious. Yet with discussion and deliberation a consensus is reached. The policies of our Association should always be decided by this body. However, since the House is only in session for 3 days each year, the Board of Directors must take over the operations of our organization. Here we must trust our elected representatives to make decisions for the good of us all. The operative word here is “trust.” Select

How fortunate are we as dentists that we can know our leaders and trust what they tell us to be true.
consent on many of our procedures. Faced with the need for consent forms in our offices, each of us would like to go to the TDA website and print out a form for whatever procedure we are contemplating. In reality, such consent forms should be designed by an attorney who is willing to go with his or her client and defend the forms should they be called into question. The TDA does not practice law and give legal advice. We have, however, come upon a process that will provide for us a governmentally certified form and list of procedures with possible complications. We all know that informed consent is a conversation that occurs between a dentist and a patient, not a form. But for a listed procedure, having discussed the associated possible complications with your patient, if you use the form and had your patient sign that you had had the conversation, you have a very defensible state supported argument that informed consent was given.
For a number of years, members have requested that the TDA design and furnish informed consent forms to bring our dentists into compliance with the Texas State Board of Dental Examiners’ requirements for written informed
This process is now in place for medicine in Texas through the Texas Department of State Health Services, Texas Medical Disclosure Panel. Last Friday, TDA program manager Ms. Cassidy Neal and I visited a meeting of the Texas Medical Disclosure
your representatives with care and then entrust and empower them to operate in your best interests during your absence. If you attempt to write rules to replace judgment you will paralyze the functionality of the TDA. The most successful organizations and businesses in our country are characterized by three steps: 1. careful selection, 2. good training, and 3. empowerment. Please keep this in mind as you make your decisions this weekend. Things happen in our world at a frighteningly rapid pace. Since I wrote this speech, our CIA and Navy Seals have located, killed, and buried Osama bin Laden! As I listened to the news while driving to San Antonio yesterday, the debate raged on whether to release photos of bin Laden’s body to prove to the skeptics that he was indeed dead.
Dr. Ronald L. Rhea, President
Panel. The members of the panel seemed very willing to help us in providing a list of services we perform that require written informed consent, a list of possible complications for each procedure, and a form upon which to list these and have the patient sign. The panel is in place to help doctors inform their patients and is not in any way punitive. Use of the forms is at the discretion of the doctor. I urge you at this meeting of the House, to empower the Board of Directors to go forward with this process. The Board can then return to you a state approved form and list of procedures with possible complications. You may then exercise your professional judgment to elect to use this form and list. We have accomplished many things this year, but two stand out in my mind. On February 23rd the TDA Extension building was officially opened and on February 24th and 25th we held our first Board meeting in the new facility. The Extension will provide us with a state of the art Board room and meeting space and additional leasable square footage. This year also marks the beginning of the new TDA state
student organization. The TDASO, which is the first state student group in the nation, was the creation of our 2009 TDA Externs, Summer Adkins, Blake Johnston, and Megan Holme. We are proud to have some of the 2011-2012 officers with us today as guests of the House. Would those officers please stand? The goal of these officers for the next year will be to build student awareness of the organization and to educate their peers about organized dentistry. We thank you for volunteering to serve and are here to support you in your new roles. I would be totally remiss if I failed to thank those who make
the operations of the TDA possible. All of us dentist volunteers are experts in our fields, but never once in all my years in the TDA office in Austin have I ever found myself with a dental drill in my hand! Fortunately, we do have experts in the central office. Many of our staff have multiple college degrees in such things as accounting, public policy, ethics, meeting management, English composition, and on and on. Without our superb staff, the TDA would not have the cachet it enjoys in Austin and at the ADA. I thank you all for allowing me this opportunity to serve.

The 141st Annual Session of the Texas Dental Association
Dr. Jerry S. Long, ADA 15th District Trustee Trustee’s Address to the Texas Dental Association House of Delegates, May 7, 2011 Good morning everyone! This will be my fourth and final report to the TDA House of Delegates as your 15th District Trustee. It’s been quite an honor for me to represent the dentists of Texas in Chicago as your Trustee for the past 4 years. Being part of the managing body of American Dental Association (ADA) is an enormous responsibility, and I promise you that I have not accepted it lightly. Thanks for your trust. During the past 4 years, ADA has undergone many positive changes. Allow me to list a few of these highlights: • • •

Almost all of the senior management in Chicago is new. The ADA Foundation and our for-profit subsidiary, ADABEI have undergone almost total reorganization. The audit process in general and the Audit Committee specifically, have moved into the post-Enron era by transforming itself into a true watchdog of the financial and reputational risks of your ADA. A Board of Trustees initiative added

two members of the House of Delegates to sit on the Audit Committee with four Trustee members. The external and internal audit firms were replaced with KPMG and RMS McGladrey to provide a new direction in the audit process. It’s been a whirlwind of activity on the ADA financial front. ADA’s new strategic plan emphasizes an unprecedented commitment to member dentists, while maintaining our longstanding commitment to our patients and the nation’s public health. Opened new avenues of collaboration with diverse groups in the profession. Dentists and dental leaders of the future will not look like the demographic represented in this hall today. Especially rewarding for Texas is that we saw action in the 2010 ADA House that validated many of TDA’s longstanding positions on midlevel providers and scope of practice. Recently negotiated an exciting, new internet public relations project for ADA with Dr. Oz, Harpo Productions (Oprah Winfrey) and the founder of WebMD, that will reach millions of Americans with oral health messages and answers to their questions, while re-

directing internet traffic to ada.org. We are hopeful that this will also result in more opportunities to enhance our non-dues revenue in the future. The website is sharecare. com. ADA’s debut is still a few weeks away, but log on for a preview. Debuted a new, revamped ada.org.
Time does not permit me to list all of the recent accomplishments of ADA; however, to paraphrase the 1970’s Peggy Lee song, “Is That All There Is”: “If that’s all there is my friend — then let’s keep dancing — let’s break out the booze and have a ball. If that’s all there is.” Unfortunately there is more. Success and celebration must be tempered with caution, because an organization such as ADA, despite all of the good news, always seems to have another challenge or threat lurking right around the corner. Today, I would like to talk about recent trends in four areas of our Association that concern me, and the potential for any one of these issues to threaten the very foundation of ADA: membership, revenue, dental education, and accountability to governance. But haven’t those “concerns” been with us forever? Absolutely!
ADA 15th District Trustee Dr. S. Jerry Long of Houston addresses the 2011 TDA House of Delegates.
However, new developments have made the board refocus its efforts and resources on making certain these concerns are not ignored. Let’s start with membership. I know you’ve heard me say this before, but here goes again: “No members, no ADA; no ADA, no profession.” And let me congratulate the Texas Dental Association because through the efforts of all of you, the TDA staff, and your component societies, the ADA 15th Trustee District will send three additional delegates and up to three alternates to next year’s House of Delegates. Only a handful of Trustee districts gained members in the recent calculations performed every 3 years. Most of the districts stayed the Texas Dental Journal l www.tda.org l June 2011

same (ADA policy states that the House grows to provide for increasing membership, with little or no chance a district will lose delegates in the reapportionment.) Membership is a good news/bad news proposition. The good news: since 2007, ADA membership has increased. And the bad news — the market share of all U.S. dentists that ADA represents has decreased from 71 percent to 68.2 percent from ’07 to 2010. The “pie” is larger, but ADA’s slice is getting smaller. Also, never has our profession seen such diversity in membership; and never before has ADA had to make itself fit into so many different expectations being brought to the table by our newest colleagues. Men, women, blacks, Hispanics, Asians, first or second generation Americans, rural, urban, the Boomers, and the Gen X’s and Y’s — we all come with our own unique set of demands of how ADA must relate to us personally. Paraphrasing President Kennedy, whatever happened to “Ask not what ADA can
522
Texas Dental Journal l www.tda.org l June 2011
do for us, ask what we can do for ADA.” Ladies and gentlemen, there’s a new member mentality in our profession. Incidentally, the diverse groups I mentioned (excluding Caucasian males) are demographic categories that produce members at around the 50-60 percentile range, and some below 50 percent. If young dentists truly are evaluating memberships on what ADA does for them, the perception is we are not meeting their needs. Further complicating the future of membership is the approaching retirement of the most loyal group of ADA members, the Traditionalists and Baby Boomers. It doesn’t take a calculator to see the potential long term effect these trends will have on the future market share of ADA dentists. Last year in this House, I mentioned the alarming news that recent graduates of our three Texas schools were in the bottom half of all dental schools in converting new graduates to full ADA member-
Dr. S. Jerry Long, ADA 15th District Trustee ship. Many of you went back to Dallas, San Antonio, and Houston and started addressing this issue with the local schools. On the bright side, I recently attended “National Signing Day” at the Houston school and graduating seniors responded by signing almost 100 percent of their class into full ADA membership. A positive trend for the Texas schools? Let’s hope so. Just keep it up! Membership affects everything. At stake are the standards of the profession from ethics to education, our advocacy efforts in federal and state legislatures on behalf of our practice and businesses — not to mention that member dues are the largest source of ADA revenue.
policy that uses a portion of the reserves to maintain a manageable dues structure; extraordinary legal and accounting expenses associated with recent changes in senior management; as well as, an increasing reluctance for Houses of Delegates to grant dues increases. These membership and financial concerns are realities that ADA trustees, staff, the Finance Committee, and the Audit Committee have lived with during my four years on the board. Is there a magic bullet for all of this? Probably not! But growing the market share of our membership is a good place to start.
First of all, dues revenue is flat, and predicted to trend downward as the Baby Boomers and Traditionalists retire and are replaced by the more diverse member groups.
To switch direction, let’s take a look at dental education. Government funding in today’s economy remains a problem, especially when our schools depend on grants to stoke the fires of the science and research components of dental education. State funding for the Texas schools is in the 20-30 percent level, and I understand that the State of California only provides 11 percent of its dental schools’ revenue.
Other factors challenging the financial health of the association are: the economy (return on the investment of reserves and “sticker shock” from dues statements); the reorganizations of ADABEI and the Foundation and their associated legal and accounting expenses; our dues stabilization
Over the next 10 years, I have heard that possibly 10-15 new dental schools will be coming online. The applicant pools continue to increase because dentistry remains an attractive career choice — increasing tuitions and huge student debt seem not to matter.
Did I just mention revenue? You bet I did, and it just happens to be the second pillar of concern that I want to discuss with you.
A large number of these new schools are branches of osteopathic medical centers and they are utilizing revolutionary, and new educational models that are, quite frankly, foreign to traditional health science center dental schools. This new approach features predominantly off site clinical instruction to small groups of students in public health settings and Community Health Centers, and many of these osteopathic institutions have very limited or no clinic facilities at their central campus. Osteopathic teaching models utilize a more streamlined approach to the basic sciences and research. Permanent full-time faculty members are small in number, since part time and visiting lecturers are often utilized. Less emphasis on research is not uncommon. This new brand of dental education is being touted as an important factor in improving access to oral health care, and as a system that produces dentists with a greater sense of social responsibility. And where is the ADA in all of this? To date, the Council on Dental Accreditation (CODA) has been involved in providing oversight and accreditation to ensure that this new approach maintains the traditionally high standards of American dentistry.
Texas Dental Journal l www.tda.org l June 2011
523
Dr. Jerry S. Long, ADA 15th District Trustee There are some who question whether CODA will eventually be forced to compromise those standards, just to keep all dental education institutions and their unique models, under the same umbrella. If ADA is about anything, it’s about maintaining high standards in all aspects of the profession. How the standards of our profession evolve in the future to accommodate this new trend in dental education, will certainly affect the standing of dentistry in the eyes of our patients, society, and government policy makers. ADA must get this right away! It’s always good to think out of the box — but not too far out of the box — because there are probably many good reasons that box is there in the first place! This year, the House of Delegates Mega Discussion will feature Dr. Jack Dillenberg, dean of A.T. Still School of Dentistry and Oral Health in Arizona and Dr. Michael Glick, dean of SUNY/ Buffalo School of Dentistry, presenting their cases for each type of dental education. That will be interesting! My fourth and final point concerns governance and the roles officers and delegates must play for the benefit of our profession. Ever avoid buying a raffle ticket because the rules of the contest said, “You have to be present to
524
Texas Dental Journal l www.tda.org l June 2011
win”? Making the extra effort to claim “the prize” can be very difficult at times. Yesterday, we attended our TDA regional caucuses to choose our delegates to the 2012 House of Delegates. Hopefully, those elected will make a full effort for our profession to “claim its prize.” Last year, I was very disappointed in the ADA House of Delegates when that body voted not to receive attorney-client information that I — and seven other Trustees — believed to be vital to the best interest of the ADA. In my mind, that vote was about apathy and irresponsibility on the part of a majority of the delegates in the 2010 House. Lesson learned for me: You can’t force feed members of the House — unless, they are committed to the exercise of their duties and responsibilities. If the ADA House of Delegates is truly the supreme “governing authority” of ADA, the 2010 ADA delegates, in my mind, fell short of their fiduciary responsibilities to 150,000+ dentists. A former president of the TDA, Dr. Michael Vaclav, honored his leadership team in 1996 by designating them as “Keepers of the Profession.” Those words and that theme have stayed with me over the years. Today, all of you have been designated “Keepers of the Profession”
by virtue of your seats in this House. Please take that responsibility seriously in the conduct of your business this weekend. Another TDA president and former ADA trustee, Dr. Frank Eggleston, once told me that he never made a decision as ADA trustee that he did not ask himself the question: “When I cast this vote, how will it affect the dentists on Main Street in Houston”? I took this to heart and have followed his advice in my trustee position for the past 4 years. This model has been a tremendous measuring stick during my time as your trustee, and is certainly worth remembering as you serve your colleagues from along Main Street in your home towns. What’s the future of American dentistry? Have we already fired our best shot and its only downhill from here? If you answer that question, “Yes”, then “let’s keep dancing, let’s break out the booze and have a ball — if that’s all there is”. If your answer is, “Heck no! — the best is yet to come,” then roll up your sleeves and go to work — all of you — “Keepers of the Profession.” There is much left to be done. It’s been a pleasure representing the dentists of Texas and the ADA 15th Trustee District over the past 4 years. Thanks for the honor!
We’ve howdied but we ain’t shook yet! It’s time we got to know one another. Wherever you practice dentistry in Texas, you carry the risk of a claim or lawsuit. Is your dental liability coverage strong enough to protect you?

Next I would like to introduce two special people who have traveled a long way to share this special event with me. My favorite sisters, Christine Coleman, a registered nurse is from Tulsa, Oklahoma, and Cindy Kessler, an accountant and business owner, is from New Orleans, LA. My brother, Ronald Coleman, could not come because his daughter is graduating from Tulane University this weekend. Family: April McLain also known as #1 is our first born. She says that she was the most wanted. April & Glenn have been married 18 years. They have one handsome son, Forrest McLain, who is 10 years old. They live in Bulverde, Texas. Glenn has been with USAA about
15 years in their IT department. April earned a bachelor’s degree in nutrition at the University of The Incarnate Word in San Antonio. She wrote a column in the Express News for 10 years in the Food and Wine section. She is presently in an internship that will complete her requirements for her Dietitians License. Vanessa Pehl also known as #2. They live in Round Rock, Texas. Vanessa says she was the favorite. Her husband, Gavin, is a financial analyst for the Dell Corporation. The Pehls are the parents of my two beautiful granddaughters Julea, 11, and Sophia, 8. Vanessa is a graduate of the Southwest Texas State University in San Marcos. She earned her bachelor’s de-

the 2010 independent Audit Report, the total report is 40 pages. Granted it’s complicated and your understanding of the report may be limited by your accounting knowledge and experience as well as your interest in understanding the facts presented. I intend to see that the Board of Directors at each of its meetings and you as delegates receive complete information in an organized format to help you fulfill your over site responsibilities. George Bernard Shaw, said “The problem with communication is the illusion that it has been accomplished.”
The TDA encourages membership and involvement in organized dentistry from the earliest days of the formation of our young dentists. This past year we have helped to establish the Texas Dental Association Student Organization (TDASO). The TDASO will work closely with the American Dental Student Association (ASDA) and will provide additional leadership opportunities that introduce the strength we have as a professional organization. TDA supports the mentoring programs of the three Texas dental schools. We encourage involvement of our retired members in local societies and in charitable events throughout the state, many of which are sponsored by TDA The Smiles Foundation. As a result of these membership efforts, the TDA received awards from ADA for the greatest net gain of new dentists, the greatest net gain of nonmembers and the greatest net gain overall in membership in 2010. These are but a part of a longer list of such awards.
What is the best measure of the greatness of our organization and our profession? There are several points one might consider: • How are the youngest and oldest members treated? • What opportunities does it offer to outsiders? • How does it respond to the needs of the membership as a whole?
The TDA seeks opportunities to communicate with people outside the organization. The TDA web site offers articles on dental health as well as articles explaining the relation of oral disease to systemic disease. Also it provides information about dental insurance, public assistance programs like Medicaid and CHIP and information about charity clinics across the state.
~~~~~~~ A wise person once observed that, “You don’t need to know all of the answers. No one is smart enough yet to ask all of the questions!” Dissecting this observation leads one to understand that although you don’t need to know all of the answers but you surely need to be thinking on your feet because questions asked by our members are important to more than one member. Many of these questions are two edged swords. If you answer one way, you please some and are insensitive to others while if you choose another side you offend the first. So which way do you go? How do you answer? You could give your honest opinion but when you speak for the organization, the “me” is not important. It’s the “we” that counts. In recent years there has been a great deal of turmoil in many areas of organized dentistry and the TDA has not been immune to this trend. The knee jerk reaction has been to make drastic changes in everything. Change should be made thoughtfully and carefully. The TDA is about as “transparent” as an organization can be (if you like that term). An example is our budget process and financial reports to the House of Delegates. Including the budget, budget explanation, financial report, supporting reports, and
528

The leaders it chooses and follows? How does it honor its heritage?
Dr. J. Preston Coleman, 2011-12 TDA president, is pictured with his wife Sue Ann.
Dr. J. Preston Coleman, President-Elect Although the term “Access to Care” continues to be a mantra in the legislative world it has yet to be defined and explained. Nonetheless the TDA has taken a leadership role to provide quality care for people in need of care. We all know the details of our significant increase in Medicaid providers at the settlement of the Frew law suit. The Medicaid and CHIP children in Texas have reaped the benefits. Daily and weekly I see children referred to my practice who have perfect or near perfect oral health. But now we are faced with two more issues. The budget crisis that has swept state governments across the nation has not spared Texas. At this time the Texas Legislature has proposed taking the Medicaid program for children from a “fee for service” model to a “managed care” model. Our Council on Legislative and Regulatory Affairs (CLRA) has been working tirelessly since before the legislative session began as soon as the plan was revealed to protect the interest of the children that benefit from the programs and to steer an outcome that will maintain the enthusiasm of our members who provide the needed care. In my estimation, our lobby team in this legislative session has guided us through the greatest mine field I can recall in 27 years of political involvement with TDA and DENPAC. To quote our sitting president, “make no mistake.” Make no mistake, we will not be doing business as
usual in the Medicaid and CHIP arena but your CLRA leadership will diligently work toward a solution that will do the least harm to the patients we serve. We were warned by our lead lobbyist, Dr. David Sibley, of the contentious legislative atmosphere before the beginning of the session and indeed there is a shortage of friendly canine pets in Austin since January of this year. The other issue is the continued pressure by private foundations namely the infamous Kellogg (sugar cereal) Foundation and the PEW (we know better than you) Foundation. They are pouring millions of dollars into state political arenas nationwide to tell the public and the dental profession how mid-level providers can provide the same quality of care that a dentist provides. I think you know the song and verse “...a mid-level provider with a high school diploma plus about 2 years of mostly un-supervised “on job training” can provide comparable care to that provided by a DDS or DMD who has a college degree and 4 years of intense didactic and supervised clinical training. Well I won’t bore you with the details that you already know but suffice it to say the DHAT report on 5 years of DHAT care in Alaska was far from convincing and even with the excuses offered showed no evidence that their hypothesis has been proven. But “make no mistake” (remember the famous American) we will have real prob-
lems if they bring their large wagons of money and their “dog and pony show” to Texas for our 2013 legislative session. The legislative arena has been on fire this year and CLRA has responded in every way possible to protect the interest of our members. I refer to the opposition the insurance industry has mounted against us. After diligent negotiation on the topic of “the capping of non-covered dental services,” a compromise was struck and we were told that the insurance industry would not oppose the compromise. Along with the old saying “the check is in the mail,” we now find our lobby team responding to their opposition. And who knows how much money has been pumped into the debate! The roller coaster ride has begun and it’s only a matter of days until we know the outcome. If you are called upon to contact your legislators this week or next, PLEASE make it a priority and act immediately because your response could be the one that sways the outcome. (Enjoy the wisdom of our Texas founders limiting our legislative sessions to 140 days every other year.) The TDA has maintained an “arm’s length” and a constructive relationship with the Texas State Board of Dental Examiners (TSBDE). The recent vote by TSBDE to implement the proposed new rules and regulations governing Anesthesia and Sedation Permitting was not supported by all Texas Dental Journal l www.tda.org l June 2011
529
Dr. J. Preston Coleman, President-Elect of our members. Patient care and safety are the important points. In light of the ADA’s polices on this subject changes were needed. The TSBDE has long been criticized over its disciplinary actions. There are some people who think that every violation is deserving of license suspension or revocation. In a spirit of fairness and justice the TSBDE has established an “Investigative Process Flowchart” and a “Disciplinary Matrix” to help licensees and the public understand the process. The goal being to increase voluntary compliance while lessening complaints that those violations are not dealt with in a severe fashion. One of the goals of the TDA 2014 Strategic Plan is “Public Image”. This House of Delegates has been briefed on the progress of this goal by the Task Force on Public Image. The TDA Smiles Foundation has had a strong influence on Public Image since its beginning. The TDA Smiles Foundation programs, Texas Missions of Mercy, Texas Smiles on Wheels, and Donated Dental Services, have put the profession’s reputation in the spot light in many communities across the state. These efforts have literally changed lives for people in most need of a fresh start in life. These efforts are our most effective public relations activities to date. The TDA, thanks to its dedicated membership, has consistently elected strong leaders who have
530
Texas Dental Journal l www.tda.org l June 2011
consistently contributed to the strength of the organization. Today at the ADA level, Dr. Jerry Long has served as the ADA 15Th District’s Trustee. Dr. Long has served us well in a sometimes hostile and lonely environment in Chicago. He has staunchly defended the principles we stand for and consistently delivered our message to the ADA Board of Trustees. Dr. Patricia Blanton, past TDA president, serves as 2nd Vice President of the ADA. She has been well received in Chicago and also presents our point of view consistently. ADA 2009 president and TDA past president Dr. John Findley led the ADA through some of its hardest times in that year. Dr. Hilton Israelson, past TDA president, will be taking office as the ADA 15th District Trustee upon Dr. Long’s retirement. There are many other Texans who have served on councils and committees and in offices at the ADA level. They all deserve our appreciation and thanks. I am honored to follow a long line of officers who have willingly given their time and effort to the TDA and its causes. I would like to mention Dr. Rick Black, past TDA president, and present CLRA chair. Dr. Black and his council along with Dr. David Sibley and our lobby team practice the “dark arts” in the political arena. Dr. Black is nearing the end of his third legislative session and I know he can’t wait for the closing gavel. Dr. David May,
past TDA president and former chair of FSI, and my mentor Dr. Dick Smith, past TDA president and past secretary-treasurer, and many others deserve our thanks. I cannot fail to mention and express my gratitude to Dr. Ron Rhea and Dr. Matt Roberts who have helped me prepare for the challenges that lie ahead. And there are many, many others, one of those dentist I have to mention at this time. From my earliest exposures to organized dentistry I was in awe of a man who was so generous to and caring of our profession. He never stopped giving well past his retirement. Dr. Robert V. Walker who passed away last week was that person. I am so honored to have known this wonderful man for more than 40 years. What is the noblest profession of all? In my estimation and according to something I read, the noblest profession in life is one that allows you to use all of your talents, most of the time, for many of the nicest people, to achieve meaningful results. The worst profession in life is one in which you can work for a lifetime and earn nothing but money. And so the heritage of our Association continues the persistent challenge to be the “VOICE OF DENTISTRY IN TEXAS,” to advocate for our members and our patients in the political arena, to BE the “keeper of our profession,” and to provide “Health Care That Works.” Thank you again for this honor!

Introduction Elastics are commonly used in orthodontics to apply force at various vectors. The most common elastics are made of latex, but non-latex alternatives have also been developed. In dental offices in particular, latex allergies are predicted to be one of the most common allergies (1). In addition to

The purpose of this study was to compare the force loss of ¼ inch (6.35mm) 3.5oz (99g) medium latex elastics from Ormco Corp. to non-latex elastics from ClassOne Orthodontics and Phoenix after being cycled between different temperatures. Elastics were stretched to 1.57 inches (40mm) on jigs and cycled in water baths for 4 minutes at 5˙C and 37˙C, 21˙C and 37˙C, 5˙C and 50˙C, 37˙C and 50˙C, and a control group was held at 37˙C. The force produced by new elastics and elastics after incubation was measured using a Mini 44 Instron. Results: All elastics experienced increased force loss that correlated with increased temperatures with the exception of Ormco latex elastics. The latex elastics had the greatest force loss upon cycling between 5˙C and 50˙C while the non-latex elastics had the greatest force loss while cycling between 37˙C and 50˙C. All elastics were strongest when cycled between 5˙C and 37˙C. Conclusion: This study suggests that hot liquids reduce the force of latex and non-latex elastics even when cycled between hot temperatures for brief periods of time.

Elastics being hypoallergenic, ideal orthodontic elastics would also maintain a constant force for the duration they are used in the oral environment. The majority of research on latex and non-latex elastics have been focused on the force produced after static or cyclic stretching (2-8). Russel et al. demonstrated that medium latex and nonlatex elastics maintained 80-85 percent of their force after 1 hour of static extension (2). Further, Kersey et al. discovered that four brands of non-latex elastics undergoing 1 hour of cyclic extension and relaxation under water maintained 75 percent of their original force (4). Other studies found that after 48 hours of in vivo use, latex elastics maintained 61 percent of their force. In comparison to the above studies, less has been done concerning the effect of temperature on elastics. Genova et al. demonstrated that power chains undergo greater force loss when cycled between 15°C and 45°C water when compared to being held at 37°C (10). Stevenson and Kusy demonstrated that nonlatex power chains incubated for 10 days at 44°C maintained less of their force than those incubated at 34°C (11). These studies focused on power chains instead of interarch elastics. Beattie and Monaghan took on the difficult task of testing the effect of a simulated diet on elastics, but the study had too many variables to draw a clear conclusion about the effect of temperature alone (12).

Although the current body of literature explains a great deal about orthodontic elastic force loss, there is still much to be discovered. This study tested the effect of cycling latex and nonlatex interarch elastics between water baths at various temperatures to understand how elastics respond to intermittent temperatures.
MATERIALS AND METHODS All elastics used were ¼ inch (6.35mm) diameter, 3.5 ounce (99g) orthodontic elastics (Z-Pack Fox latex elastics from Ormco Corp, Glendora, CA; non-latex elastics from ClassOne Orthodontics, Lubbock, Texas, and Phoenix, Blue Springs, Missouri). All elastics were tested soon after being received from the companies and long before their expiration dates. Elastics were chosen randomly from five bags of the same lot from each company for all experiments. Twenty new elastics from each company were used for the initial force measurement and for each of the experiments for a total of 300 elastics for this study. Each elastic was stretched to 1.57 inches (40mm) when dry to measure their force using a universal testing machine (Mini 44 Instron, Instron, Canton, MA). A measure of 40mm was chosen as an approximation of the distance between a maxillary lateral incisor and a mandibular 2nd molar when the mouth is closed. For each experiment the elastics were stretched to 40mm on jigs and then submerged in distilled water and either cycled between water baths of 5˙C and 37˙C, 21˙C and 37˙C, 5˙C and 50˙C, 37˙C and 50˙C, or held at 37˙C for 4 minutes. Each experiment lasted 4 minutes and consisted of 20 cycles of 3 seconds in each water bath. The two water baths were part of an apparatus that had temperature sensors, cooling and heating coils, and a mechanical arm that automatically transferred a basket containing the samples between the water baths that were held at the desired temperatures. The entire
process for all experiments was continually monitored to ensure that the water baths were at the appropriate temperature and that the transfer apparatus functioned properly. The bands were removed from their baths and their force measured once the experiment was complete. The force data were analyzed using a two sample T-test assuming equal variance (Excel, Microsoft Corp., Redmond, Washington). Standard error bars were also calculated and displayed on Figure 1.
RESULTS Both latex and non-latex elastics displayed a correlation between greater force loss and higher temperature water baths (Figure 1). Ormco latex elastics, however, experienced the greatest force loss during the 5˙C and 50˙C cycle, which was statistically significant (P<0.05) when compared to the 37˙C control. There were also statistically significant (P<0.05) differences between brands when one of the water baths was 50˙C. The difference within brands was statistically significant (P<0.05) when comparing to the 37˙C control, except for the 21˙C and 37˙C cycle for Ormco latex and Phoenix non-latex elastics and the 5˙C and 37˙C cycle for Ormco latex elastics.

Elastics DISCUSSION As mentioned previously, the effect of cyclic temperatures on orthodontic elastic force loss has received little attention in research journals. Tran et al. found that interarch non-latex elastics lose force more rapidly than latex elastics when they are incubated at 37˙C in simulated saliva (13). This experiment suggested latex and non-latex elastics respond differently in a simulated oral environment. Paige et al. found that interarch non-latex elastics experience greater force loss than latex elastics at elevated temperatures (14). That study suggested that temperature may play a key role in the amount of force elastics are able to produce. The temperatures and cycle times used in this study may loosely correlate to the temperatures of beverages people regularly consume and the time they are in the mouth. A temperature of 50˙C was chosen since it was a temperature that is warm but will not burn the mouth and had been used in a previous study (14). The 5˙C temperature was chosen because it was the coldest temperature our instruments could reliably maintain throughout the course of the experiment. Overall, we found that as the temperatures of the water baths increased so did the loss of force of the elastics. The difference in force between brands of elastics and elastics within a brand
544
Texas Dental Journal l www.tda.org l June 2011
when compared to the control became more pronounced at elevated temperatures. The only exception was the 5˙C and 50˙C cycle for Ormco latex elastics which had the greatest force loss for that brand (Figure 1). This result was unexpected but may reveal that latex elastics are sensitive to cycling between hot and cold temperatures. Our data supports previous papers that suggest that non-latex elastics are more sensitive to higher temperatures than latex elastics (14). This difference is likely due to fundamental differences in the two materials. For example, latex is a natural product consisting of cross-linking and covalent bonds between chains while non-latex elastics are synthetic polymers that rely on weaker hydrogen bonds and van der Waals forces to hold chains together. These weaker bonds can be disrupted by water (15). Studies of the degradation products of elastics in water suggest that the initial force degradation is caused by weaker intermolecular forces and then later by chemical degradation (15). This study supports previous literature that elevated temperatures result in accelerated force loss for non-latex elastics when compared to latex elastics. Further, this study demonstrates that even relatively short periods of intermittent elevated temperatures a result in a statistically significant loss of force. These results add to the growing body of evidence that even though patients are instructed to change their
elastics regularly, hot liquids may have a deleterious effect on the force produced by their elastics. In particular those patients who consume hot liquids soon after placing their elastics may experience reduced force from their elastics for the duration they are worn. Although further research is needed, it may be prudent for patients, especially those wearing nonlatex elastics, to change their elastics after consuming hot liquids. Further research is needed to determine the clinical significance of this study.
CONCLUSION •
•
This study suggests that non-latex elastics undergo greater force loss than latex elastics at intermittent elevated temperatures. Latex elastics lose the most force when cycled between hot and cold temperatures.

Adhesive Dentistry and Endodontics Contamination of the Root Canal System One of the primary goals of root canal treatment is to eliminate bacteria from the root canal system to the greatest possible extent (2, 3). Bacteria have been shown to be the etiology for apical periodontitis and to be the cause of endodontic failure (2–5). One of the goals in restoring of the tooth after root canal treatment should be to prevent recontamination of the root canal system. Gross contamination can occur during the restorative process from poor isolation or poor aseptic technique. Contamination can also occur from loss of a temporary restoration or if leakage occurs. The same things can occur with a “permanent” restoration, but “permanent” materials tend to leak less than temporary materials (6). Exposure of gutta-percha to saliva in the pulp chamber results in migration of bacteria to the apex in a matter of days (2, 7–9). Endotoxin reaches the apex even faster (10). The importance of the coronal restoration in successful endodontic outcomes is widely accepted and has been supported by studies by Ray and Trope, Hommez et al., Tronstad et al., Iqbal et al., and Siqueira et al (11–14). However, studies by Riccuci et al., Ricucci and Bergenholz, Heling et al., and Malone et al. indicate that contamination may not be as important a factor in failure as is commonly believed (2, 15–18). Therefore, it must be concluded that the significance of bacterial contamination as a cause of endodontic failure is not fully understood. Because there is clearly no benefit to introducing bacterial contamination into the root canal system, and since it may be a contributing factor in endodontic failure, a basic premise of this review will be that every effort should be made to prevent contamination.

Temporization To minimize the likelihood of contamination, immediate restoration is recommended upon completion of root canal treatment (19–21). When immediate restoration is not possible, and the tooth must be temporized, a thick layer of temporary material should be used, preferably filling the whole chamber. The majority of restorative dentists prefer a cotton pellet in the chamber, however (22). If a cotton pellet or sponge is to be used, orifice barriers are recommended to provide a second layer of protection against contamination in addition to the temporary material at the occlusal surface. Recommended procedure for placing orifice barriers: 1. Countersink the orifice with a round bur. 2. Clean the orifices and floor of the pulp chamber thoroughly with alcohol or a detergent to remove excess cement and debris. Air abrasion provides a dentin surface that is free of films and debris. 3. Place a temporary or “permanent” restorative material in the orifices and over the floor of the chamber. A bonded material such as composite resin or glass ionomer cement is preferred (23–27). Temporary materials may also be used (28). Mineral trioxide aggregate (MTA) may also be used (29). There is probably some benefit to using a material that is clear so that the restorative dentist can see the underlying obturating material if re-entry is needed into the canal system (1) (Figure 1). Results varied in studies that evaluated temporary materials for the access cavities (21, 30–36). The most common materials tested were zinc oxide eugenol (such as IRM, Dentsply Int.), zinc oxide/calcium sulfate (Cavit, Premier Corp.) or resin based materials including composite resin and resin modified glass ionomer materi-

als. Generally, all of the temporary materials were adequate if placed in a thickness of 3 mm or greater (21, 33â&#x20AC;&#x201C;36). All temporary materials leak to some extent (20, 21, 37â&#x20AC;&#x201C; 40). The zinc oxide/calcium sulfate materials are more resistant to microleakage than the zinc oxide eugenol materials, probably because of setting expansion and water sorption (21, 33, 34). Although the zinc oxide eugenol materials tend to leak
more, they possess antimicrobial properties, making them more resistant to bacterial penetration (21, 34, 41). Both materials are simple to use. One study reported less leakage with the use of two materials in combination (42). Resin based temporary materials must be bonded to provide an effective seal, because they undergo polymerization shrinkage of 1 to 3 percent (30, 43). This is offset somewhat by the
fact that they swell as they absorb water (30). Generally, bonded resin materials provide the best initial seal, but lack antimicrobial properties (30). They require more steps and more time to place than materials such as IRM or Cavit. Bonded resins are recommended for temporization that is likely to last more than 2 to 3 weeks (42, 44). Resin modified glass ionomer materials are also a good choice for long term temporization because they

Adhesive Dentistry and Endodontics provide a bond to dentin and enamel, and many have antimicrobial properties (44). Teeth requiring temporary post/ crowns are a particular challenge because of the difficulty in obtaining a good seal (45, 46). To minimize the chances of contamination of the obturating material, a barrier may be placed over it with a self-curing material. The post space should be restored as soon as possible and it may be beneficial to flush the post space with an antimicrobial irrigant when the temporary post is removed.

Restoring Access Openings When an access opening is made through an existing restoration, several things should be considered. Removal of all existing restorations is desirable if possible because it allows more complete assessment for the presence of cracks and caries (47). This is particularly recommended for old class 1 and class 2 restorations because they are likely to be removed later anyway in the process of preparing the tooth for a crown. Magnification and caries detector are helpful in identifying cracks and for complete removal of caries (48). If the existing restoration is a crown or onlay that appears to be clinically satisfactory and replacement is not planned, the chamber and internal restorative materials should be examined carefully with magnification. Caries detector should be painted on the internal tooth surfaces. Any areas stained by the caries detector, particularly adjacent to restorations, should be examined carefully for softness or gaps (Figure 2). Caries detector may also stain sound areas of dentin that have decreased mineral content (49). The key to the presence of caries is determined by whether the stained areas are hard or soft. Many times caries can be identified internally, necessitating replacement of the crown. Access openings made through an existing restoration results in loss of retention and strength (50â&#x20AC;&#x201C;53). When the access opening is restored, loss of retention is reversed (51, 52). If a post is added, additional retention is gained (51).

Ideally, we would like to restore access cavities with a restorative material that provides a permanent, leak proof seal. Unfortunately, no such material is available. All materials that we use and restorations that we place leak to some extent. This includes intracoronal restorations including bonded resin and glass ionomer materials as well as the metal or ceramic extra-coronal restorations (38, 54–56). To minimize leakage, bonded restorations are recommended, regardless of the restorative material (6, 57). Access openings are made through a number of different restorative materials, including gold alloys, base metal alloys, and porcelain, as well as enamel and dentin. Bonding to each of these substrates present specific challenges which require specific strategies and materials. Often the access opening is prepared through two or three different substrates. The structural integrity of the tooth may also influence the choice of restorative materials. Each substrate will be addressed separately.
Bonding to Enamel Enamel is often present along the margins of access preparations of anterior teeth. The resin bond to etched enamel is strong and durable. The technique dates back to 1955 (58). Etching of enamel with an acid such as 30 to 40 percent phosphoric acid results in selective dissolution of the enamel prisms and creates a surface with a high surface energy that allows effective wetting by a low viscosity resin. Microporosities are created within and around the enamel prisms that can be infiltrated with resin and polymerized in-situ (59). These “resin tags” provide micromechanical retention. Bond strengths are typically in the range of 20 megapascals (Mpa) (60). Megapascals are a measure of the force per unit area that is required to break the bond. Self-etching adhesive systems, which will be discussed in the section on bonding to dentin, etch ground enamel fairly well, but do not etch unground, aprismatic enamel effectively (61– 63). Therefore, enamel margins should be beveled when using self-etching adhesive systems. It is critical to prevent contamination of etched enamel with blood, saliva or moisture (64). Poorly etched enamel leads to staining at the margins of the restoration (65). A good enamel bond protects the underlying dentin bond which is less durable (66).
Bonding to MetalCeramic and All-Ceramic Restorations Access cavities are often made through metalceramic or all-ceramic materials, so attaining an effective, durable bond is important when restoring them. The literature is unambiguous that the best method to bond to porcelain is to first roughen the surface by acid etching and then apply a silane coupling agent, followed by the resin (67–70). Bond strengths of 13 to 17 Mpa have been reported, and failure is often cohesive within the porcelain, meaning that the interfacial bond strength exceeds the strength of the porcelain itself (71–73). Bonding to porcelain was initially developed as a method for repair of fractured metalceramic crowns. Improvements in the technique allowed porcelain veneers to become a common clinical procedure. Etched ceramic materials form a strong, durable bond with resin (74). Micro mechanical bonding can be attained by roughening the porcelain with a bur, air-abrasion or etching with hydrofluoric acid. However, acid etching is the most effective method (73, 75, 76). The first to introduce acid etching of porcelain was Calamia in 1983 (77). Adhesion between the resin and porcelain may be enhanced by the use of a silane-coupling agent. Silane acts as a surfactant to lower surface tension and forms double bonds with OH groups in the porcelain, forming a siloxane bond. At the other end of the silane molecule is a methacrylate group that copolymerizes with resin. The use of a silanecoupling agent with porcelain was first described by Rochette in 1975 (78).
Hydrofluoric Acid
Hydrofluoric acid provides greater surface roughness to porcelain than air abrasion or roughening with a bur (75). It works by dissolving the glass particles (leucite) within the porcelain (Figure 3). Most of the porcelains used in metal-ceramic restorations are feldspathic porcelains that contain leucite. Some ceramic materials, such as low fusing porcelains, do not contain leucite and are not etched effectively by hydrofluoric acid (79). However, hydrofluoric acid is effective with most of Texas Dental Journal l www.tda.org l June 2011
551
Adhesive Dentistry and Endodontics the current ceramic restorative materials (80–83). Hydrofluoric acid is usually provided in a 10 percent concentration in a syringe. It is very important to follow the manufacturer’s instructions, as an application time that is too short will produce an inadequate etch, while an application time that is too long may render the porcelain brittle and thus more prone to fracture (84).
Silane
Silane acts as a “coupling agent” enhancing the bond between the resin and ceramic materials. It is supplied premixed or as a two bottle system that is mixed at the time of use. It is applied to the etched surface and must be thoroughly air dried (85). A low viscosity resin adhesive is then flowed over the surface and polymerized. Once again, it is very important to follow the manufacturer’s instructions. Silane has a limited shelf life. Storage in the refrigerator will extend its useful life, but it should be used at room temperature (86). The two bottle silanes have the longest shelf life (71). Silane that is past the expiration date or that contains precipitates should be discarded (86).
Air Abrasion
Air abrasion is sometimes recommended to clean the porcelain and provide surface roughness. Several companies sell “micro-etchers” that can be used

chairside. Aluminum oxide particles are sprayed onto the surface at about 80 psi. Fifty micron particles have been shown to produce a more retentive surface than 100 m particles (87). Two studies reported that air abrasion has a negligible effect on bond strength, however (76, 88). Etching and application of silane are the two most important steps.
Cosmetics
When restoring the access cavity of a ceramic crown, it is often a challenge to produce a good cosmetic result. Many times it is difficult to mask the underlying metal of a metal-ceramic crown. This is particularly true if the porcelain is thin. It is not uncommon to see the metal showing through the composite. The second challenge is to match the optical properties of the porcelain. This is true for metal-ceramic crowns as well as all-ceramic crowns. Most composites are too low in value (too gray and translucent) to effectively match the surrounding porcelain (Figure 4). Several products are available that may be used to mask the underlying metal before the restorative composite is placed. Most of these are composite resins that contain opaquers. They may be covered with more translucent composite materials. Several composites are available that are quite opaque and work well when restoring access cavities in metalceramic crowns. Composite stains can be used to accentuate pits and fissures to further enhance the cosmetic result (Figure 5).
Several studies have shown tin plating of metal enhances mechanical retention (92â&#x20AC;&#x201C;96). Chromium plating also works well (96). Plating devices are available that can be used intraorally. Although effective, this procedure has never gained popularity. Metal primers are an alternative that enhances the bond between metal and resin. They have been shown to be effective and do not require any special equipment (97â&#x20AC;&#x201C;99).
Bonding to Dentin: Resin Materials Bonding to dentin with resin materials is more complex than bonding to enamel or porcelain. Dentin consists of approximately 50 percent inorganic mineral (hydroxyapatite) by volume, 30 percent organic components (primarily type 1 collagen) and 20 percent fluid (100). The wet environment and relative lack of a mineralized surface made it a challenge to develop materials that bond to dentin. Current strategies for dentin adhesion were first described by Nakabayashi in 1982, but his ideas were not widely accepted for a number of years (101). Nakabayashi showed that resin bonding to dentin could be obtained
Bonding to Metal
The metal portion of metal-ceramic crowns is not usually significant when restoring access openings, so no extra procedures are necessary to deal with it. However, for crowns in which all or part of the occlusal surface is metal, adhesion may be desirable. Adhesion to metal is generally obtained by mechanical means. Surface roughness may be created with a bur or air abrasion, which provides micromechanical retention (89). Chemical adhesion is also possible with metals that form an oxide layer (90). Silane has no effect on bonding to metal (91).

Adhesive Dentistry and Endodontics by applying an acid to expose the collagen matrix and dentinal tubules, applying a hydrophilic (“water loving”) resin material to the demineralized surface and polymerizing the resin in situ. The collagen matrix and dentin tubules, to a lesser extent, provide mechanical retention for the resin. Although not as durable and reliable as enamel bonding, steady improvements have been made in dentin bonding and in simplifying dentinbonding procedures.
Figure 5. With knowledge of color, translucency, and occlusal anatomy, beautiful results are achievable when restoring access cavities with composite resins.
Most in vitro studies of dentin bonding report on bond strengths, microleakage, or both. Like enamel, bond strengths are usually reported in Mpa. Depending on the test method used, initial bond strengths can be obtained that are equal or greater to those of etched enamel. However, dentin bonding is not as durable as enamel bonding or as stable. It is well documented that bond strengths decrease with time and function. This has been shown in vitro and in vivo (66, 102–111). Microleakage is probably a more important issue to endodontics than bond strength. None of the current adhesive systems are capable of preventing microleakage over the long term (65, 112–117). There is not a direct relationship between bond strength and microleakage (116). Dentin adhesive systems utilize an acid as the first step of the bonding process to remove or penetrate through the smear layer and demineralize the dentin surface. The smear layer covers the surface of ground dentin and consists of ground up collagen, hydroxyapatite, bacteria, and salivary components (59). Most dentin adhesive systems can be categorized as “etch and rinse” or “self etching,” based on the acid etching process (59).
“Etch and Rinse” Adhesives
Most of the “etch and rinse” adhesive systems utilize a strong acid such as 30 to 40 percent phosphoric acid. When phosphoric acid is applied to dentin, the surface is demineralized to a depth of about 5m. The acid is rinsed off after about 15 seconds, removing the smear layer and exposing the collagen matrix and network of dentinal tubules for resin bonding. A hydrophilic primer is then applied to the surface to infiltrate the collagen matrix and tubules. The primer contains a resinous material in a volatile carrier/solvent, such as alcohol or acetone, which carries the resinous material into the collagen matrix and dentinal tubules. The surface must be wet (moist) for the primer to penetrate effectively. After the primer is in place a stream of air is used to evaporate the carrier and leave the resin behind. A hydrophobic (“water hating”) resin monomer (adhesive) is then applied and polymerized, which adheres to the infiltrated resin from

the primer. A “hybrid layer” or “interdiffusion zone” is formed that consists of resin, collagen and hydroxyapatite crystals (59) (Figure 6). It bonds the hydrophobic restorative materials to the underlying hydrophilic dentin. Poor bond strengths and increased microleakage result from excessive etching (118). The same is true if residual carrier/solvent is left behind, which makes the bond more subject to hydrolytic breakdown (119).
“Self Etching” Adhesives
Most of the “self etching” products combine an acid with the primer. Rather than removing the smear layer, they penetrate through it and incorporate it into the “hybrid layer.” The acidic primer is applied to the dentin surface and dried with a stream of air. There is no rinsing step. A resin adhesive is then applied and polymerized, followed by the restorative material. The “self etching” systems can be categorized as “strong” or “aggressive” (pH 1), “moderate” (pH 1–2) or “mild” (pH 2) (59, 120, 121). The strong “self etching” systems form a hybrid layer of approximately 5m in thickness, similar to phosphoric acid, whereas the mild systems form a hybrid layer of about 1 micron (120, 121). There does not appear to be clinical significance to this difference in thickness, however (121). The
“strong” systems generally produce a superior bond to enamel than the “weak” systems, particularly with unground enamel (59, 61– 63).
and 6th generations are generally two step procedures, while the 7th generation combines everything (acid, primer and adhesive) into one step.
Dentin Adhesive “Generations”
Many of the “self etching” products require fewer steps and less time than the “etch and rinse” products, and are considered to be less “technique sensitive” (59). There are still a number of questions about them, however, such as the unknown effects of incorporating partially dissolved hydroxyapatite crystals and smear layer into the hybrid layer. There is also the question of how much of the carrier/solvent remains behind. Because they are relatively new, there are currently no long-term clinical studies with the “self etching” adhesive systems. The three step adhesive systems generally perform better in in vitro testing than the adhesive systems that combine steps, although the differences lessen with time as the bonds degrade (59, 65,
Many of the “etch and rinse” adhesive systems require three steps (etch, primer, adhesive), and are known as “4th generation” adhesive systems. The “generation” of a dentin adhesive generally follows the order in which they were developed and each “generation” utilizes different bonding procedures. The “5th generation” adhesive systems are “etch and rinse,” followed by application of a combined primer and adhesive. These are sometimes referred to “single bottle” adhesive systems. Some require several applications of the primer/ adhesive, however. The “6th generation” adhesives utilize an acidic (“self etching”) primer followed by an adhesive. The 5th

Adhesive Dentistry and Endodontics 66, 107, 121, 122). The “self etching” adhesive systems are also less effective than the “etch and rinse” systems when bonding to sclerotic dentin and caries effected dentin (123, 124). They also have compatibility problems with some composite restorative materials, which will be discussed in the section on self-cure and dual-cure composites. The single step (7th generation) adhesives are a fairly recent addition to the market. At this point in their development, they produce consistently lower bond strengths in vitro than the others and are not compatible with self-cure or dual-cure composites (59, 107, 121, 125, 126). Most of the current research is directed toward improving the performance of the simplified adhesive systems, and they will probably continue to improve. Some of the common acronyms used in resin bonding are shown in Table 1. Examples of commercial dentin bonding systems are shown in Table 2.
Wet Bonding
Most adhesive systems utilize “wet bonding.” If the etched dentin surface is dried excessively, the collagen matrix collapses and prevents effective infiltration of the primer. The result is low bond strengths and excessive microleakage (127–129). Excessive moisture has similar negative effects on adhesion (128, 129). An effective method to provide the proper amount of moisture is to dry the surface thoroughly and then rewet it with a moist sponge, so that the surface is damp, but there is no visible pooling (127, 130).
tooth structure (131). They form an ionic bond to the hydroxyapatite at the dentin surface and also obtain mechanical retention from microporosities in the hydroxyapatite (132, 133). Glass ionomer materials form lower initial bond strengths to dentin than resins, on the order of 8 Mpa. But unlike resins, they form a “dynamic” bond. As the interface is stressed, bonds are broken, but new bonds form. This is one of the factors that allow glass ionomer cements to succeed clinically, despite relatively low bond strengths. Other factors are low polymerization shrinkage and a coefficient of thermal expansion that is similar to tooth structure. Some glass ionomer materials also possess antimicrobial properties (134–136). When placing glass ionomer cements, the surface is cleaned and then treated with a weak acid such as polymaleic acid (131). The acid removes debris from the dentin surface, removes the smear layer, and exposes hydroxyapatite crystals. It creates microporosities in the hydroxyapatite for mechanical retention, but there is minimal dissolution (131, 133). Because glass ionomer cements rely on ionic bonding to the hydroxyapatite, strong acids should be avoided because they cause almost total elimination of mineral from the dentin surface (137). Traditional glass ionomer cements are not widely used for clinical procedures because they set slowly and must be protected from moisture and dehydration during the setting reaction, which in many cases is not complete for 24 hours. They are also relatively weak and generally not as esthetic as other restorative materials.

Adhesive Dentistry and Endodontics cements. RMGI materials contain glass ionomer cement to which a light-cure resin is added. The purpose of the resin is to allow immediate light polymerization after the material is placed. The resin also protects the glass ionomer cement from dehydration, and improves the physical and mechanical characteristics and optical properties. True RMGI materials utilize similar bonding procedures as glass ionomer cements and do not require a dentin-bonding agent.
Endodontic Issues in Dentin Bonding Some of the materials used in endodontics may have a significant impact on the bonding process. These issues apply not only to restoration of access cavities, but also to the obturating materials that utilize adhesive resin technology, which will be discussed in a subsequent article.
Eugenol
In endodontics, eugenol containing materials are widely used in sealers and temporary filling materials. Eugenol is one of many substances that can prevent or stop the polymerization reaction of resins and can interfere with bonding (138, 139). If resin bonding is planned for a dentin surface that is contaminated with eugenol, additional clinical steps are needed to minimize the effects of the eugenol. The surface should be cleaned with alcohol or a detergent to remove visible signs of sealer. Many temporary cements, whether they contain eugenol or not, leave behind an oily layer of debris that must be removed before bonding procedures (140, 141). Air abrasion is an effective method for cleaning the dentin surface (Figure 7). Once it is clean, the dentin should be etched with an acid, such as phosphoric acid and then rinsed. The acid demineralizes the dentin surface to a depth of about 5m and removes the eugenol rich layer. Several studies have shown that the “total etch” (three step) procedure allows effective bonding to eugenol contaminated dentin surfaces (24, 142).
558
Texas Dental Journal l www.tda.org l June 2011
An “etch and rinse” adhesive system should be used, because the “self etching” systems incorporate the eugenol rich smear layer into the hybrid layer, rather than removing it. Eugenol has no effect on glass ionomer cements (143).
Sodium Hypochlorite
Sodium hypochlorite is commonly used as an endodontic irrigant because of its antimicrobial and tissue dissolving properties (144). Sodium hypochlorite causes alterations in cellular metabolism and phospholipid destruction. It has oxidative actions that cause deactivation of bacterial enzymes and causes lipid and fatty acid degradation (144). Several studies have shown that dentin that has been exposed to sodium hypochlorite exhibits resin bond strengths that are significantly lower than untreated dentin (145–149). One study reported bond strengths as low as 8.5 Mpa (147). Increased microleakage was also reported (150). This phenomenon probably occurs because sodium hypochlorite is an oxidizing agent, which leaves behind an oxygen rich layer on the dentin surface. Oxygen is another substance that inhibits the polymerization of resins (151). Morris et al. showed that application of 10 percent ascorbic acid or 10 percent sodium ascorbate, both of which are reducing agents, reversed the effects of sodium hypochlorite and restored bond strengths to normal levels. Lai et al. and Yiu et al. reported similar results (149, 150). Because sodium hypochlorite is likely to remain the primary irrigant used in endodontics for the near future, and because adhesive resin materials are used routinely in restoring endodontically treated teeth, this issue will have to be addressed. Future adhesive resin products for endodontic applications may contain a reducing agent to reverse the effects of the sodium hypochlorite. A nonoxidizing irrigant would also solve this problem. Sodium hypochlorite and EDTA have also been shown to reduce the tensile strength and microhardness of dentin (152). These are particularly timely issues for endodontics as adhesive resin materials gain popularity as obturating materials.
Other Materials Applied to Dentin
Other materials that are applied to dentin during endodontic procedures have been tested for their effects on bonding. Not surprisingly, hydrogen peroxide leaves behind an oxygen rich surface that inhibits bonding (147, 148). Reduced bond strengths were shown after the use of RC prep (Premier) (146). Electro-chemically activated water has gained a following as an irrigating solution. It probably reduces bond strengths of adhesive resins because it has the same active ingredient as sodium hypochlorite, i.e. hypochlorous acid (153, 154). No loss of bond strength is reported from chlorhexidine irrigation before resin bonding or placement of resin-modified glass ionomer materials (147, 155–157). Caries detector did not affect resin bond strengths, but chloroform and halothane resulted in significant loss of bond strength (158–160).
Restorative Materials Silver Amalgam Alloy
Not surprisingly, silver amalgam alloy is the most common choice for restoring access cavities in metal crowns (161). The clinical technique is simple, with few steps, and provides a durable restoration. “Bonded amalgam” is often recommended in which a resin adhesive is placed on the cavity walls before condensation of the amalgam alloy (57). The adhesive provides an immediate seal. When amalgam alloy is used without an
adhesive, it leaks initially, but “self seals” with time as corrosion products form at the amalgam interface with tooth structure or other restorative materials (162). One strategy to use with amalgam alloy, that offers theoretical advantages, is to seal only the chamber floor and orifices with adhesive resin to provide initial protection of the root canal system from contamination. With time the amalgam restoration will corrode at the other interfacial areas and provide a seal that may be more durable than resin. There is a theoretical advantage to using ad-mixture alloys over pure spherical alloys. Ad-mixture refers to a mixture of spherical and lathe cut particles. Ad-mixture alloys have slight setting expansion, which tends to reduce leakage, whereas spherical alloys shrink slightly while setting (163).
Composite Resin
Not surprisingly, composite resin is the most common choice for restoring access cavities in ceramic restorations (161). Composite can be bonded to tooth structure and most restorative materials, and can provide a good match of color and surface gloss. Bonded composite materials can also strengthen existing coronal or radicular tooth structure, at least in the short term (164, 165). The limitations of composite resin as a restorative material are primarily related to polymerization shrinkage. Restorative resins are reported to exhibit shrinkage in the range of 2 to 6 percent during polymerization (43, 166). Less filler (such

Adhesive Dentistry and Endodontics as found in “flowable” composites) results in more shrinkage (166, 167). Polymerization shrinkage causes stress on the adhesive bond that often results in gap formation (43). One study reported the percentage of dentinal gaps found in vivo was 14 to 54 percent of the total interface (168). Marginal deterioration of composite restorations expedites the loss of dentin adhesion (169).
Self-cure materials may be bulk filled because they do not require penetration with a curing light. They polymerize more slowly than lightcure materials, allowing the material to flow during polymerization contraction, and placing less stress on the adhesive bond (43, 167). The same is true for dual-cure materials in the areas that are not irradiated by the curing light.
Composite restorative materials come in several forms: light-cure, self- (chemical) cure or dualcure. Light-cure materials consist of a single paste and polymerization is initiated with a curing light. Self-cure materials consist of two pastes that are mixed together to initiate polymerization. Dual-cure materials also consist of two pastes that are mixed together to initiate polymerization, but may also be light activated. Dual-cure materials have the advantage of rapid polymerization in the areas irradiated by the curing light, but chemical polymerization occurs in areas the light can not reach.
The problem with polymerization shrinkage is amplified in access cavities because of a concept known as C-factor or configuration factor (43, 167). C-factor refers to the ratio of bonded surfaces to free or unbonded surfaces. The higher the C-factor, the greater the stress from polymerization shrinkage (43). Restorations with C-factor higher than 3:1 are considered to be at risk for debonding and microleakage (170). In a class 5 restoration, the ratio might be 1:1. In an access cavity, the C-factor might be 6:1 or even 10:1. In a root canal system obturated with a bonded resin material, it might be 100:1 (43).
Light-cure materials polymerize in a matter of seconds and generally have the best physical properties. However, they have several disadvantages. Because of the rapid polymerization, they tend to stress the adhesive bond to tooth structure more than the slower self-cure composites (167). The stress is sometimes so great that the restorative material debonds at the weakest interface (43, 170). For example, in class 5 composite restorations, they tend to debond at the interface with cementum, which forms a weaker bond than enamel (54). Because most curing lights can only effectively polymerize a thickness of 2 to 3 mm of composite material, cavities must be filled incrementally, a time consuming and tedious task. An access cavity may require 3 to 5 increments. Because curing lights lose intensity with distance, the light intensity may be greatly reduced at the floor of the chamber when curing through an access opening in a crown. In addition, it may not be possible to irradiate all areas inside an access cavity because of undercuts or difficulty in obtaining the proper angle with the light.
An incremental filling technique with light-cure composite resins partially overcomes the problem of C-factor. Incremental filling is possible because atmospheric oxygen prevents complete polymerization on the external surface of the resin. This oily surface is referred to as the “oxygen inhibited layer (151).” Because of the unpolymerized surface layer, additional increments may be added and polymerized and a strong chemical bond is formed between increments (151). Incremental filling allows complete polymerization of each increment, and lessens the stress from polymerization shrinkage because the C-factor is more favorable for each increment than if the cavity was bulk filled (171, 172). Another strategy to lessen the effects of C-factor is to use slow setting selfcured materials that flow during polymerization, thus reducing stress (31, 167).

If contamination occurs with blood or saliva during incremental filling, the bond between increments may be ruined. However, if the surface is rinsed, dried and a dentin adhesive is applied, there is no loss of bond strength (173).
Glass Ionomer Cement and Resin Modified Glass Ionomer Materials Both types of glass ionomer materials may be bulk filled. Most of the RMGI materials are dualcure. Traditional glass ionomer cements are selfcure and have very little polymerization shrinkage. Because resin is added to RMGI materials, they exhibit some polymerization shrinkage, although less than composite resins. Both types of glass ionomer materials are useful for bulk filling access cavities. Even though they bond to tooth structure, the bond strengths are too low to provide significant strengthening effect (174).
Material Incompatibilities
The “self etching” adhesive systems have generally been shown to result in low bond strengths when used with self-cure composites and dualcure composites that have not been light activated (126, 175–178). This is in part because of residual acid on the dentin surface. Self-cure composites contain tertiary amines in the catalyst that initiate the polymerization reaction and have a high pH. Loss of bond strength results because residual acid from the acidic primer inhibits the basic amines, resulting in incomplete polymerization at the interface between the adhesive and the restorative material (175, 176, 179, 180). Dualcure composites exhibit bond strengths comparable to light-cure composites in the areas that are effectively light-cured, because they are not dependent on the basic amines (177). One study reported lower bond strengths with the self-cure composites than light-cure composites with “etch and rinse,” single bottle (5th generation) adhesives as well (181). The second problem with many of the “self etching” adhesive systems is that they act as permeable membranes. This is a problem when they are used with restorative materials that polymerize slowly. A permeable adhesive layer allows penetration of moisture from the dentin to the interface with the restorative material, which is hydrophobic (122, 179). Moisture penetration can result in a phenomenon known in polymer chemistry as “emulsion polymerization,” in which
there is poor adaptation between the adhesive and restorative material (122). Moisture at the interface probably also contributes to the degradation of the bond over time (122).
Clinical Strategies Most strategies for restoring access cavities require several steps and at least two layers of restorative material. Many approaches utilize an adhesive system and two restorative materials. The exception is unbonded amalgam alloy.
Restoring Access Cavities with Tooth Colored Materials
Light-cure composite can be used to fill the entire access cavity if it is filled incrementally. This method will provide the strongest bond to tooth structure and is the preferred method when it is necessary to maximize the tooth strengthening effects of the restoration (181). When executed with skill and knowledge of the materials, excellent esthetic results are possible (Figure 8). However, this is a slow, time consuming method. High initial bond strengths are also obtained with dual-cure composites that are placed incrementally and light polymerized (177). This method may be preferred to incremental fill with purely light-cured materials if there are concerns about light penetration to all areas of the cavity. As discussed earlier, the 4th generation adhesive systems are preferable for endodontic restorative applications with composite materials. They tend to form the best bond to dentin, and have few compatibility problems with restorative resins. They are also effective despite the use of eugenol containing sealers or temporary materials. A method to restore access cavities in teeth with ceramic restorations: Light-cure composite. 1. Clean the internal surfaces with a brush or cotton pellet containing a solvent such as alcohol. 2. Sandblast the cavity, metal and ceramic, or lightly refresh them with a bur. 3. Etch the ceramic with hydrofluoric acid or other appropriate etchant. 4. Rinse and dry. 5. Apply phosphoric acid to the inside of the access cavity if restoring with composite. Etching with phosphoric acid adds no retention Texas Dental Journal l www.tda.org l June 2011

to porcelain, but it cleans the porcelain and enhances the silane adaptation (182). 6. Rinse and dry. 7. Apply silane agent to the porcelain and dry. 8. Apply a dentin primer and adhesive to the internal walls and light cure. 9. Fill the cavity incrementally with no increments greater than 3 mm. 10. Light cure each increment for 40 seconds (time depends on type of light used). 11. The restoration should be slightly overfilled so it can be finished back to the margins. 12. Contour and adjust the occlusion. 13. Finish and polish the restoration. In many cases, it is desirable to bulk fill most of the cavity with a glass ionomer material or selfcure or dual-cure composite, then veneer it with a light-cure composite material that is esthetic and will withstand occlusal function. This method is more efficient than using a purely light-cure composite, but the esthetic result may not be as good. A simple method to restore access cavities in teeth with ceramic restorations: Glass ionomer and composite. 1. Treat the dentin with a polyalkenoic acid for 30 seconds. 2. Bulk fill with a dual-cure glass ionomer material to within 2 to 3 mm of the cavo-surface margin and light cure. 3. Etch the ceramic material with 10 percent hydrofluoric acid, or other suitable etching gel for 1 minute, depending on the product. 4. Rinse and dry. 5. Apply silane to the etched ceramic surface and air dry. 6. Apply the dentin primer and adhesive to the glass ionomer material and etched ceramic and light cure. 7. Place the first increment of light-cure composite. The first increment should include the longest vertical wall and taper to the base of the opposing vertical wall. 8. Light cure for 40 seconds (time depends on type of light used). 9. Fill the remaining space with the second increment and light cure. The restoration should be slightly overfilled so it can be finished back to the margins. 10. Contour and adjust the occlusion. 11. Finish and polish the restoration.
A Simple Procedure for Composite Resin The procedures are similar to those described with glass ionomer material, but a 4th generation dentin adhesive system is used on the dentin and a dual-cure composite is substituted for the glass ionomer material. 1. Treat the dentin and enamel, if present, with 30 to 40 percent phosphoric acid for 15 seconds. 2. Thoroughly rinse and dry the dentin then rewet with a moist sponge. 3. Apply primer and adhesive, following the manufacturerâ&#x20AC;&#x2122;s instructions. 4. Bulk fill with a dual-cure or self-cure composite to within 2 to 3 mm of the cavo-surface margin and light cure. 5. Etch the ceramic material with 10 percent hydrofluoric acid, or other suitable etching gel for 1 minute. 6. Rinse and dry. 7. Apply silane to the etched ceramic surface and air dry. 8. Apply the dentin primer and adhesive to the etched ceramic and light cure for 15 seconds. 9. Place the first increment of light-cure composite. The first increment should include the longest vertical wall and taper to the base of the opposing vertical wall. 10. Light cure for 40 seconds. 11. Fill the remaining space with the second increment and lightcure. 12. Contour and adjust the occlusion. 13. Finish and polish the restoration. Dual-cure composites that are bulk filled develop relatively low bond strengths to dentin, comparable to glass ionomer materials. Resin adhesives lose bond strength with time and function, whereas glass ionomer bond strengths are relatively stable. So there is little if any benefit to the use of dual-cure composites over glass ionomer materials for bulk filling the cavity.

Figure 8 (continued). (E) A dentin primer is applied to all internal surfaces and air dried, and a dentin adhesive is applied to all internal surfaces and light polymerized. (F) A flowable composite is injected into the orifices and on the chamber floor and polymerized. This method minimizes voids between the restorative material and dentin. Because it is somewhat translucent, it makes location the canals easier if re-entry is necessary at a later time. (G) Incremental build-up, light composite over dark. Increments should be only 2 to 3 mm in thickness to allow adequate polymerization. (H) Application of opaque composite. This is often necessary when restoring metalceramic crowns that tend to be quite opaque.

Conclusions 1. Prevent contamination of the root canal system. 2. Restore access cavities immediately whenever possible. 3. Use bonded materials. 4. The 4th generation (three step) resin adhesive systems are preferred because they provide a better bond than the adhesives that require fewer steps. 5. The “etch and rinse” adhe-
sives are preferred to “self etching” adhesive systems if a eugenol containing sealer or temporary material was used. 6. “Self etching” adhesives should not be used with self-cure or dual-cure restorative composites. 7. When restoring access cavities, the best esthetics and highest initial strength is obtained with an incremental fill technique with composite resin.
8. A more efficient technique which provides acceptable esthetics is to bulk fill with a glass ionomer material to within 2 to 3 mm of the cavo-surface margin, followed by two increments of light-cure composite. 9. If retention of a crown or bridge abutment is a concern after root canal treatment, post placement increases retention to greater than the original. Texas Dental Journal l www.tda.org l June 2011

Oral and Maxillofacial Pathology Case of the Month Clinical History This 45-year-old Hispanic female presented to her new family dentist for routine care. The dentist noticed dozens of small, asymptomatic “brown bumps” along the lateral borders of her tongue (Figure 1). She claimed that these had been present and unchanged since childhood. The pigmentation was strongest on the tips of the papules and the papules were generally a uniform 2 mm in diameter, although several were very much smaller than that (Figure 1B, insert). There was no other pigmentation in the mouth. Her medical history was unremarkable for systemic diseases and, to the best of her knowledge, no other family member had similar “bumps” on their tongue. The dentist biopsied one of the papules and the biopsy showed melanin deposits concentrating in the epithelium near the top of the mass, with abundant melanin seeming to have “dropped off” into the subepithelial stroma (Figure 2).
What is the final diagnosis?

Oral and Maxillofacial Pathology Diagnosis and Management
Papillary Tip Melanosis (Pigmented Fungiform Lingual Papillae) Oral and Maxillofacial Pathology Case of the Month (from page 572)
Discussion The dorsal surface of the tongue is, after the floor of the mouth, the least common oral location for melanotic macules and focal melanosis, but occasional patients, especially those with dark skin pigmentation, will present with irregular light-brown to dark-brown macules of that surface (1). This is called physiological or “racial” pigmentation and, typically, the fungiform papillae are spared such pigmentation. Occasional patients, however, will present with papillary tip involvement in combination with more routine mucosal melanosis (Figure 3) and some, like our patient, will present with no melanotic macules, only pigmentation of the tips of the fungiform, and sometimes filiform, papillae. The concentration of pigment at the papillary tips is not surprising, since this portion of the fungiform papilla develops embryologically from a distinct subset of epithelial cells from which taste buds will develop after birth (2). Epithelium from the base of the papilla is more similar to the rest of the oral mucosa and, in fact, has molecular markers suggestive of actual suppression of the kind of dense cells seen at the tips of papillae. Be that as it may, there seems to be no significance to the presence or absence of a background melanotic macule or the presence of such macules elsewhere in the mouth.

Texas Dental Journal l www.tda.org l June 2011
We have recently suggested the term papillary tip melanosis (PTM) for this entity (3). PTM is a simple recognition problem, since no treatment or biopsy is required, and the clinical appearance does not at all suggest an ominous diagnosis. In our experience, these “brown bumps” are life-long entities, probably starting in childhood (or at birth), becoming more pronounced during adolescence and the teen years, and changing very little after that. In this regard, PTM follows the same pattern as physiologic pigmentation (1). We do not believe that this is a new entity, but is, rather, an “orphan disorder” that has always been present in a certain number of individuals but has not been taught because it has remained unnamed, at least in dentistry. In truth, there is a remarkable lack of information in the dental literature about PTM. It has never been discussed as a unique entity or variant of oral melanosis, except for a photo in the detailed and excellent recent review by Meleti et al. of oral pigmentation (4). It was also pictured in an old but highly regarded textbook of oral pathology, the Tiecke book, published in 1965 (Figure 4) (5). Unfortunately, the photo is used incorrectly in the book to illustrate a strawberry tongue of scarlet fever. This dearth is particularly odd since several case reports have been published in the pediatric and dermatology literature, beginning with
a 1967 report (6-13). At least one group of physicians has suggested, in fact, that PTM is quite common, being found in at least 25 percent of adult blacks in their relatively select group of patients (7). That has certainly not been our experience. We recently presented a small series of only 13 new cases, including the first cases in Hispanics (it had only been reported previously in African Americans and Asians), and this appears to be the only series thus far reported in the dental literature. The medical literature, while reporting PTM, has not established a common diagnostic name for this tongue lesion, although some have suggested pigmented fungiform papillae of the tongue (PFPT), black taste buds, or black lingual bumps. We have suggested PTM as a more logical diagnosis because some of our cases, including the present one, demonstrated melanosis at the tips of filiform papillae in addition to the fungiform papillae (Figures 1B and 5). The embryologic explanation for papillary tip filiform involvement is less understandable than the fungiform involvement, but the pigment does seem to concentrate in the superior portions of both types of papillae. It is well known that oral melanosis, in addition to being a racial or ethnic feature, may be produced by certain medications. One of our cases, as seen in Figure 5, did indeed show increased pigmentation with the use of ketoconazole medica-

Papillary Tip Melanosis tion for unrelated candidiasis. The increase was dramatic enough, in fact, that the patient wasn’t even aware of pigmented papillae prior to use of the drug. After drug cessation, the pigmentation diminished dramatically, although a mild brown discoloration remained. This experience has led us to believe that any medication capable of producing oral melanosis (Table 1) should also be capable of producing or enhancing PTM pigmentation. In a similar vein, a variety of syndromes (PeutzJeghers, Bloom, McCune-Albright, Laugier-Hunziker) and systemic diseases (Addison, neurofibromatosis, xeroderma pigmentosum, Carney complex, hemochromatosis) have been associated with oral melanosis, but no one has yet reported the PTM variant in those disorders. We present, then, the first dental journal summary of PTM and suggest that it has one of the more strange histories as an oral pathology “disease” entity, in that it occurs exclusively in the mouth and has, with very, very few exceptions, been reported only in the medical literature.

Strategies for Improving Patient Understanding and Compliance Kathleen M. Roman, MS; Medical Protective Company
The Challenges
How many times, in a follow-up appoint-
ment, have you discovered that a patient has ignored, misunderstood, or forgotten your
instructions? When was the last time a staff
member complained about phone calls from patients who need further instructions for
their post-procedure home care? Have you ever been shocked to discover the dangerous non-compliance of a patient, e.g., “Oh,
I didn’t know you meant one to two Vicodin every 24 hours. I thought you said one to two Vicodin every 2-4 hours”?
The resolution to these concerns lies in improving the way you and your staff provide and reinforce patient education. Over the years, you’ve probably seen many of the studies warning that patients forget somewhere between 40-60 percent of healthcarerelated instructions as soon as they leave the office. But time is money, and in today’s pressing economy, many dentists practice with one eye on the clock. After all, the patient’s insurance company doesn’t offer
580
Texas Dental Journal l www.tda.org l June 2011
extra compensation for your patient education efforts. Many doctors feel that solvency relies on their ability to finish up with one patient and move on to the next. But let’s factor in the potential “losses” that arise out of the examples above. When a patient ignores, misunderstands, or forgets your instructions, he or she may have a less-than-ideal outcome. How many times have you had to make an emergency trip to your office to treat a patient for dry socket? “Well I didn’t think it would hurt if I smoked just a couple of cigarettes.” What about repairs to orthodontic devices or broken bridges? “I forget to wear the night guard — but I still think you should fix the crowns for free.” Many times, you end up doing extra work as a free patient service and the costs associated with these additional services adds up—not to mention the inconvenience of preventable after hours calls. Every time a patient calls your office to ask for additional information or to “make sure” that he or she is complying with a home care regimen, you’re paying a staff member to manage that call and to reinforce the educational message. Hopefully, your staffer is also documenting the content of the phone call — and that may include a conversation with you to ensure that if you have additional advice for the patient, that information is also passed along. So, two people in your office, each of whom was already engaged in some other activity, are filling in the blanks for the caller, while patients who are already in the office cool their heels. And perhaps most compelling of all are those “near misses” that occur when patients dangerously misunderstand your instructions. You know who they are — the three-pack-a-day smoker who thought you said that you wanted to check that lesion again next year — when you really said next month. And then there’s the woman who decided not to tell you that she’s being treated for breast cancer — and has just completed a round of IV bisphosphonates — because she’s “embarrassed,” and, besides, doesn’t see how her medical condition is “any of your business.” So, the point is that, in many ways, you’re still being forced to engage in those patient education activities — but they’re often happening after-the-fact, when: a) the timing is much less effective; b) the intervention will cost you more money than it would have if you’d formalized the education component at the time of treatment; and c) the patient already may have sustained some sort of injury — possibly increasing your liability exposure.
Strategies Following are some strategies that might help you get a better handle on patient education. Review the education processes in your office. Encourage your staff to participate in the assessment. Your receptionist’s perspective on patient education may differ from your dental hygienist’s. Both may be valid, and their combined suggestions may be more valuable than either individual insight. Together, you and your team can get a clearer picture of how patient education can improve your practice. •
•
•
Conduct a random chart audit. Look for documentation of patient non-compliance. When you find it, look for notes that indicate the patient was given educational materials, formal written instructions, hand-written notes, encouraged to ask questions, etc. You may find a correlation between non-compliance and a lack of educational interventions. Regardless of your area of practice, many of the treatments you offer patients should include a formal (signed) informed consent. A key component of any informed consent process is the discussion with the patient about diagnostic results, treatment options, and the risk and benefits associated with each. This type of patient education is essential to the consent process. Without sufficient information — meaning “education” — a patient may be unable to make an appropriate treatment decision. And, there have been times when courts have decided that a signed informed consent document was invalid; often, these rulings note inadequacy of the information given to the patient. When you audit charts, look also for verification of patient education, discussion, and questions and answers, as a part of every formal informed consent process. Ask yourself who in your practice is engaging in patient education. As the clinician, it is your role to educate patients about their diagnoses and treatment plans. Few states allow diagnostics to be handled by anyone other than a dentist. At the same time, your hygienist is probably also an ally in terms of educating patients about their oral health, especially their home oral health regimens. And what about your dental assistants and your receptionists? Within the scope of their job descriptions, they can also be informative and helpful, but require training and acknowledgement of the topics they can address as well as the topics they must refer to you.

Patient Compliance •
•
•
If more than one dentist practices in the same office, are you using the same educational brochures/materials to educate patients? Inconsistency leads to errors. You want your entire dental team to be on the same page when it comes to educational interactions and materials. Are you handing out obsolete educational materials? Periodically, you should review your educational handouts. As dentistry changes and as your practice changes, these materials should be updated. You can write your own educational materials if you wish. Or you can contact companies that specialize in patient education. The American Dental Association and some state or professional specialty associations also have educational materials. Read educational materials carefully, especially those that might be developed by companies that want to sell clinical product. You don’t want to be held accountable for a manufacturer’s marketing hyperbole. Numerous resources for patient education and effective doctor-patient communications can be found on the Internet. Space allows just one example, but if you google “patient education,” you’ll find numerous offerings. One of these is the Teach-Back technique — an excellent resource for helping patients understand the information you want them to take away from their appointments. And, it’s relatively simple to learn.
First, explain to the patient the information that you want to share. Learning experts tell us that pictures, brief brochures, and pictographs (little sketches that you yourself might make on the patient’s chart or on a piece of paper you give to the patient) all help to reinforce retention of the information once the patient leaves. Be consistent in the process. Develop a miniscript if necessary: “Here are the X points I will always want to make when explaining this diagnosis/treatment option to patients.” Second, try not to use complicated language. For example, tell the patient, “You have a type of gum disease that is called periodontitis,” rather than, “You have periodontitis.” Use short sentences. When you’re finished explaining the information to the patient, let him or her know when you’re beginning to give instructions. In other words, this is the point where the patient knows that he or she will have to engage in some subsequent action.
582
Texas Dental Journal l www.tda.org l June 2011
Third, reinforce the information and written materials you’ve already given to the patient by saying something like, “Well, I’ve given you a lot of instructions, and I want you to be sure to ask any questions that occur to you, but just to be sure that I’ve done a good job of explaining this information, could you please repeat it back to me? Can you tell me what I want you to do at home tonight as your new tooth care plan?” And, finally, if the patient gets it right and can accurately repeat the important components of the conversation, that’s great; if not, you can go back again and try a slightly different approach. If it wasn’t clear the first time, using the exact same words the second time may not be any more effective. Tell the patient, “Well, let’s see if I can make this a little less confusing,” and then try again. The Teach Back method has proven very effective in helping many different healthcare providers reduce patient confusion and non-compliance and increase patient satisfaction as well.
Conclusion Patient education is an important component of the doctor-patient relationship. It helps ensure patient compliance, and may reduce the risks of unsatisfactory clinical outcomes. While formalized approaches to patient education may seem burdensome, in fact, they may ultimately reduce the amount of time invested per patient. And, there is evidence that teaching strategies are valuable in reducing patient risks commonly associated with non-compliance. Kathleen M.
