2010/2011 Board of Directors OFFICERS President President Elect Past President 1st Vice President 2nd Vice President Secretary/Treasurer

After reviewing past ‘Message from the President’ columns from a number of CAO Bulletins, I realized that most of the information is repeated and elaborated upon within the Board reports. Therefore, this report will be filled with preoccupying thoughts. Perhaps you can relate. For example, • Sesame Street recently axed Cookie Monster in order to placate the angry mobs protesting against unhealthy eating. Mr. Monster’s death was devastating!

Cookies (especially chocolate chip) have been a staple food in my diet since I was a little boy. Since Sesame Street is reclassifying its long standing characters, then perhaps they can tell us what kind of bird Big Bird is anyways? I’m sure the International Poultry Society (IPS) will be on that one any time now.

As a child, Big Bird can be downright frightening.

• Why does a water bottle carry an expiry date? If the bottle is past due, does the water spontaneously explode into life-threatening hydrogen and oxygen molecules when you open it?

Dr. Rick Odegaard Dr. Phil Williamson Dr. Mike Ziglo Dr. Susan Tsang Dr. Helene Grubisa Dr. Jean-Marc Retrouvey Dr. Dan A. Stuart

• How do toothbrush companies annually produce toothbrushes that ‘revolutionize’ oral hygiene? I can’t wait for the release of toothbrushes with carbon fibre handles allowing for a greater transfer of energy from your hand to your teeth resulting in the most efficient brushing ever! It works for hockey sticks and slap shots, so why not toothbrushes and teeth? As CAO President, maybe Oral B will let me into their secret laboratory, just like the one on TV, to study with their master technicians.

• God bless Oral and Maxillofacial Surgeons who charge reasonable fees to New patients who seek their expertise, knowledge and advice. Too bad there are some Orthodontists who feel their expertise, knowledge and advice is worth a lot less...even nothing! Maybe it's because we only spend three extra years of post graduate traning vs. their four?

• In Ontario, it is strictly forbidden for a dentist to treat his or her intimate partner.

Conviction will result in immediate licensure suspension. If your partner grinds his or her teeth at night and you can’t get any sleep, does that mean that you cannot make him or her a night guard? How about pleading insanity due to a lack of sleep? Or bringing home a toothbrush for your partner? Does that constitute treatment? Technically, you are treating an oral hygiene issue right?

Here’s an interesting take on this stupid law……suppose you suspect your partner of having an affair with your friend who happens to be a dentist. Request Continued…

that this dentist to do some required dental treatment on your significant other. If he or she refuses, then what does that say? Think about that one for a second!

Liaison, New and Younger Member and Scientific Session reports, to name just a few, are mere fingertips away for your reading pleasure!

• My dog is small enough to fit in a designated, “airline approved” animal carry-on bag that can be placed under the seat in front. Why do certain airlines charge fifty dollars plus tax to reserve a spot underneath the seat in front of you for a small pet and not for carry-on luggage? The size and weights are comparable. Maybe I should knock my dog out with some pet drugs and smuggle her in a backpack next time and save the surcharge.

In closing, I would like to thank Diane, Alison, Ritchie, Paul, Garry, Mike P., Rick, Phil, Mike Z., Susan, Helene, J.M., Dan S., Amanda, Gerry Z., Bob, Gordie, Stephen, Gerry S., Dan P., Richard and Jim for all their hard work and efforts. Without all of you, the CAO would not be the well-respected, progressive organization that it is. Stay tuned for more interesting personal presidential thoughts in the Fall 2011 Bulletin.

• Who cleans up the webbing that Spider Man leaves behind? New York City must be a mess by now.

Respectfully submitted, but at half the calories as other Past President’s Messages, Howard Steiman

For those who yearn for the more ‘professional’, dry stuff that you won’t find anywhere else but in this column, behold!

• The CAO is considering running a scholarship contest similar to that created by the AAO. Patients will be able to submit short videos discussing how orthodontics changed their lives. This contest is open to members’ Retention and Dismissed patients only. The CAO will be forwarding contest rules via the Bulletin and e-blasts. A cash prize towards college or university tuition will be offered to the winner. The CAO is currently examining the structure and legalities of this project with the hopes of launching the first contest next year.

• The CAO has asked the CFAO to consider providing a certificate and cash award to fourth year dental students across Canada who demonstrate outstanding achievement in undergraduate orthodontics. Pending CFAO approval, look for the first awards to be given out in 2012.

• Keeping our Past-Presidents involved in the CAO is critical.

A wealth of knowledge and experience is lost when their line commitment comes to an end. Many Past-Presidents desire to stay involved with the CAO in non-line officer positions or as a simple resource to the organization. In the Loop is a new e-newsletter where Past-Presidents will receive a regular update roughly every six weeks encompassing a wide range of topics. Now, if that isn’t a great reason for a volunteer to join the CAO line, I don’t know what is.

• The use of e-blasts, on-line membership renewal and website-only directories are just a few of the ways the CAO is doing its part to cut costs and save the environment. Preliminary programs and Scientific Session registrations will become paperless in the near future. Internally, more and more of our Board materials are making their way onto our website.

• All the other things that the CAO Board is doing on your behalf are stuffed into this Bulletin. Provincial Directors, Treasurer, CDA/CDSA Liaison, Membership, CAO-AAO

CAO Bulletin • Spring 2011

Rapport du président À l’examen de nombreux messages du président extraits d’anciens Bulletins de l’AOC, je me suis rendu compte que la majorité des renseignements fournis est répétée et approfondie dans les rapports du Conseil. Par conséquent, je vous fais plutôt part de mes préoccupations. Peut-être partagerez-vous mes sentiments. Je vous donne ci-dessous quelques exemples.

• Dernièrement, l’émission Sesame Street a fait tomber le couperet sur Cookie Monster pour calmer les foules en colère qui protestent contre les mauvaises habitudes alimentaires. Sa mort m’a atterré! Les biscuits (notamment aux brisures de chocolat) font partie de mon alimentation de base depuis ma plus tendre enfance! Puisque l’équipe de Sesame Street réoriente ses personnages établis, peutêtre peut-elle nous donner l’heure juste à propos de Big Bird. Je suis persuadé que l’OPEP (Organisation des pays producteurs de poulet) se penchera bientôt sur la question. En effet, aux yeux d’un enfant, ce volatile peut paraître carrément effrayant.

• Pourquoi les bouteilles d’eau sont-elles affublées d’une date de péremption? Si la bouteille est périmée, l’eau explose-t-elle en molécules mortelles d’hydrogène et d’oxygène dès qu’on dévisse le bouchon?

• Comment les fabricants de brosses à dents s’y prennentils pour créer chaque année un produit qui « révolutionne » l’hygiène dentaire? J’ai tellement hâte qu’on lance des brosses à dents dotées d’un manche en fibres de carbone qui transférera davantage d’énergie de la main aux dents, de sorte à créer le meilleur brossage de dents qui soit! Ça marche pour le bâton de hockey et le lancer frappé. Alors, pourquoi pas pour la brosse à dents et les dents? Puisque

je suis président de l’ACO, peut-être qu’Oral B me donnera accès à son laboratoire secret, comme celui qu’on voit à la télé, pour étudier en compagnie de ses techniciens experts.

• Dieu bénisse les professionnels de la chirurgie buccale et maxillo-faciale qui demandent des honoraires raisonnables aux nouveaux patients s’adressant à eux pour obtenir expertise, connaissances et conseils. Quel malheur que certains orthodontistes considèrent que leur expertise, leurs connaissances et leurs conseils valent beaucoup moins, voire rien du tout!?! Peut-être est-ce parce que nous ne consacrons que trois ans à notre formation de deuxième cycle plutôt que quatre, comme eux?

• En Ontario, il est strictement interdit à un dentiste de traiter son conjoint. Toute condamnation à cet égard donne lieu à la suspension immédiate du permis d’exercice. Si votre conjoint grince des dents la nuit, cela signifie-t-il que vous ne pouvez pas lui fabriquer une prothèse? Pourriez-vous plaider l’aliénation mentale consécutive à la privation de sommeil? Ou encore lui ramener une brosse à dents?

Serait-ce considéré comme un traitement? Sur le plan technique, vous traitez un problème d’hygiène dentaire, n’est-ce pas? En voici une bonne à propos de cette loi stupide… Supposons que vous soupçonnez votre conjoint d’entretenir une aventure avec un ami dentiste. Demandez à cet ami de prodiguer des traitements dentaires nécessaires à votre conjoint. S’il refuse, qu’est-ce que cela signifie? Songez-y une seconde!

• Mon chien est suffisamment petit pour séjourner dans les valises pour animaux qu’acceptent les transporteurs aériens et que je peux glisser sous le siège devant moi. Pourquoi certains d’entre eux exigent-ils cinquante dollars, taxes en sus, pour réserver un petit coin sous un siège devant vous, mais rien du tout pour un bagage de cabine? La taille et le poids des deux bagages sont comparables. Peut-être devrais-je assommer mon chien avec un médicament et le mettre dans un sac-à-dos et éviter ainsi le supplément à l’occasion de mon prochain vol.

• Qui nettoie les toiles que Spider-Man tisse tous azimuts?

New York doit maintenant se trouver dans un bel état. À ceux qui désespèrent de prendre connaissance de propos plus professionnels et arides que vous ne trouverez nulle part ailleurs que dans le présent message, poursuivez votre lecture!

• L’ACO envisage d’organiser un concours semblable à celui de l’AAO dont le prix serait une bourse d’études. Les patients pourront soumettre de courtes vidéos dans lesquelles ils diront comment l’orthodontie a changé leur vie. Ce concours est réservé aux patients dont le membre assure le suivi ou dont le traitement est terminé. L’ACO diffusera les règlements du concours par l’intermédiaire du bulletin et des communications électroniques éclairs. Un prix en argent destiné au règlement des droits de scolarité universitaires sera offert au lauréat. L’ACO examine à l’heure

actuelle la structure et la légalité de ce projet dans l’espoir de lancer le concours l’an prochain.

• L’ACO a demandé à la Fédération canadienne pour l’avancement de l’orthodontie (FCAO) de réfléchir à la possibilité d’offrir une attestation et un prix en argent aux étudiants en soins dentaires de quatrième année au Canada qui ont obtenu des résultats remarquables au cours de leurs études de premier cycle. D’ici à ce que nous obtenions l’approbation de la FCAO, attendez-vous à la remise des premiers prix en 2012.

• Il est essentiel que nous maintenions la participation de nos ex-présidents aux activités de l’ACO. Nous perdons des connaissances et une expérience précieuses au terme de leur engagement. Nombre d’entre eux tiennent à continuer de participer à ces activités à des postes non hiérarchiques ou tout simplement à titre de personnes-ressources. In the Loop est un nouveau bulletin électronique qui les informera environ toutes les six semaines sur un large éventail de sujets. Voilà un véritable incitatif en vue de se porter volontaire pour occuper un poste hiérarchique à l’ACO. • La diffusion de communications électroniques éclairs, le renouvellement de l’adhésion en direct et les répertoires exclusifs du site Web ne représentent que quelques-uns des exemples des moyens que l’ACO met en œuvre pour comprimer les coûts et pour protéger l’environnement. L’inscription à des programmes préliminaires et à l’Assemblée scientifique pourra se faire sous peu sans papier. À l’interne, un nombre croissant de documents de notre conseil est diffusé dans notre site Web. • Le reste du bulletin fourmille des autres initiatives que le conseil de l’ACO prend pour votre compte. Directeurs provinciaux, trésorier, agent de liaison entre l’Association dentaire canadienne et la CDSA, et entre l’ACO et l’AAO, directeurs des comités de l’adhésion et des membres nouveaux et plus jeunes et comptes rendus de l’Assemblée scientifique, voilà certains des sujets à portée de main pour votre plus grand plaisir!

En conclusion, je tiens à remercier Diane, Alison, Ritchie, Paul, Garry, Mike P., Rick, Phil, Mike Z., Susan, Helene, J.M., Dan S., Amanda, Gerry Z., Bob, Gordie, Stephen, Gerry S., Dan P., Richard et Jim de leur travail acharné et de leurs efforts.

Sans vous tous, l’ACO ne serait pas l’organisation hautement respectée et progressiste qu’elle est. Demeurez à l’affût d’autres commentaires présidentiels intéressants, fruits de cogitations personnelles, dans le bulletin de l’automne 2011.

Je soumets respectueusement à votre attention mon message dont le contenu contient la moitié moins de calories que ceux des ex-présidents, Howard Steiman

Committee Reports Treasurer’s Report

HST input tax credits as a refund have yet to be filed. It is anticipated that the current situation will be no different than in previous years.

Dr. Michael Patrician Treasurer [Email: drpatrician@bellnet.ca]

Insurance Report In 2010, the general operations of the CAO yielded net revenues of $14,881.65. The Scientific Session in Whistler B.C. yielded net revenue of (minus) $14,245.50. For 2010, the combined net revenue for both the general operations and the scientific session was $636.15.

The total members’ equity was $549,743.88. At the CAO meeting in Whistler, the Board voted to increase the dues by $20 to $545 + HST in response to the proposed formation of the Canadian Dental Specialty Association.

The CFAO has increased its charitable donations over the past two years to support orthodontic education in Canada as a direct result of the negotiations between the CFAO and the CRA to disburse funds from this charitable foundation. Consequently, total CDSPI investments have been reduced. After 2011, the disbursement schedule will be significantly curtailed.

The CDSPI investments total $300,396.58. Total member assets were $336,624.27 on Dec. 31, 2010. Total assets have been depleted by 25.7 percent, representing $8,750.00 for each of the six Canadian programs for a total of $52,500.00 plus $17,500.00 for the poster board presentations at the 2010 CAO Scientific Session.

HST Report Dr. Michael Patrician Treasurer [Email: drpatrician@bellnet.ca] July 1, 2010 marked the beginning of the Harmonized Sales Tax (HST) in Ontario and British Columbia. To date, the transition has been very smooth. The only requests from our members were more technical in nature rather than a request for assistance when dealing with CRA auditors. 2010 tax returns requesting

There has been little change in the FNIHB program. The regional fee disparity of more than one thousand dollars persists.

The inaugural CAO sponsored webinar was held November 17th, 2010. The ‘performance’ was expertly choreographed

by Taylor Enterprises’ Alison Nash: Thank you Alison for a job well done. The experience wasn’t overly stressful to the presenters, and the feedback indicates that the webinar was well received. There have been very few inquiries or requests for assistance from our members during the past six months.

coupons and zero-fee orthodontic consultations. Coupons and fee advertisements are legal in all fifty US states, but are prohibited in Canada. The CAO brought this disparity to the attention of the AAO and now the promotion highlights that it is not applicable in Canada.

Trends magazine bestowed top awards to the AAO for its member Career and Marketing Services including the AJO-DO, the Advertising/Marketing Toolkit on AAOinfo.org, the promotional items included the AAO Style ‘n Smile Fashion Show Goodie Bag, Emmett Smith’s mouth guard promotional material and the Bubble Wrap video.

The AAO distributed a census survey to Canadian and American members in January 2011 to examine demographic information regarding the number of new patient exams, case presentations and case starts. This updated information will be compared with past surveys to track current trends Nine of the eleven longitudinal craniofacial growth records in the USA and Canada have joined with the AAOF to create a website and database accessible to those interested in craniofacial biology and human growth. This initiative, known as Legacy 300, will be supported through silent auction, both online and at the AAO Annual Session in Chicago from May 13th to 17th, 2011.

Dr. Garry Solomon CAO/AAO Liaison [Email: hellener@lks.net]

The AAO’s original goal was to use television advertisements to educate the consumer and to direct them to the AAO website. Upon review, television was deemed a less than effective marketing tool and a new goal was set to increase market share by driving the public to orthodontic offices directly using the new tag line ‘Our expertise will make you smile’. The current message is being promoted through magazine, radio and internet advertisements as well as through direct mailers, posters and puzzles. The AAO Council on Communications has recommended the continuation of the Public Awareness Campaign beyond May 2011 making use of the same tag line but adding ‘Ask your dentist for a referral to an orthodontist’.

Scholastic Parent and Child magazine anticipates reaching 50 percent of the 18 million members of the AAO target audience of mothers, children and teens.

Committee Reports Canadian Orthodontic Educators Report Dr. Gerry Solomon Chair, Conference of Canadian Orthodontic Educators [Email: solomonstr8ner@rogers.com] In September 2010, the directors of the Canadian Graduate programs met in Whistler, BC. Dr. Ed Yen attended the CCOE for the first time as the chairman of the newly created graduate orthodontic program at UBC that commenced August 2010.

The official name of the protocol for the licensing of foreigntrained specialists is the Dental Specialist Assessment and Training Program. Acceptance is limited by available space, financial resources and available staff for all of the Canadian programs.

Currently, only the University of Toronto accepts one foreigntrained specialist per year. The University of Montreal plans to accept one student within a year while the University of Alberta plans to offer acceptance in one to two years. Neither the University of Manitoba nor the University of Western Ontario is ready to offer a position while UBC is awaiting accreditation before they potentially accept more than one internationally-trained student per year.

The Canadian graduate orthodontic programs are considering altering their 2011 acceptance date for new residents who will begin their programs in 2012 to correspond with the American Match program. At present,

only UBC is considering use of the Match.

The Canadian graduate orthodontic programs share similar curriculums and remain unified in their clinical requirements based upon on competencies outlined by the Committee on Dental Accreditation.

3M Unitek Canada once again hosted and sponsored the Educators’ Meeting on April 7, 2011 in Whistler, BC. The educators are grateful to 3M Unitek and to Silvano Brecevic, Business Manager, 3M Orthodontic Products/3M Canada for the ongoing and generous support of the CCOE/CCGOPD. Dr. Don Robertson has been Chairman of the CCOE since its inception. He has worked tirelessly to keep the momentum of this Canadian initiative alive but has decided to retire from these responsibilities. Gerry Solomon is honoured to assume the role of Chair going forward.

WFO Report Dr. Amanda Maplethorp WFO Committee [Email: a_maple@shaw.ca] The next IOC will be held in London, UK September 27th to the 30th, 2015. The British Association has requested that all national and regional orthodontic organizations consider clearing their respective calendars or consider holding a combined meeting with them in London.

The website for the eighth IOC is currently at www.wfo2015london.org, but the British Orthodontic Society is planning a more sophisticated site that permits payment for the 2015 meeting in annual installments to increase attendance and to assist the planning committee with their estimates.

The location for the 2020 IOC will be chosen in 2011. If Canada is considering a proposal, then Vancouver would be a favourite, however the location of the AAO Annual Session that year will have some influence.

The Graduate Eduators meet in Whistler, BC in April 2011, with the generous support of 3M Unitek.

Committee Reports RCDC Report

CFAO Report Dr. Gordie Organ Acting CFAO President

Dr. Hugh Lamont Orthodontic Councillor, RCDC/RCDC Liaison

[Email: gmo@drgordieorgan.com] The current members of the RCDC executive are President Garnet Packota, Vice President Lee McFadden, Past-President Rick Emery, Secretary/Treasurer Ernie Lam, Registrar Pat Main, Council Representative Hugh Lamont and Examiner-inChief Paul Jackson.

The RCDC Board now has a public member on council. An examination advisory committee consisting of five Royal College examiners, three CDRAF representatives and one public member is being formed to review the examination process and to make associated recommendations. The examination venue in Toronto is moving from the Grand Hotel to the Harbour Westin Castle Hotel due to the increase in the number of candidates and examiners involved in the process. In 2010, the RCDC exam changed from a semi to an annual process for each of the two sections. The written section must be passed prior to a candidate registering for the second sessions.

Chicago and Atlanta constitute the out-of-country written exam sites.

The year 2010 represented the second of a three-year agreement between the CFAO and the CRA to distribute approximately $38,000.00 per year; $17,500.00 has been allocated to the posterboard presentations and $8750.00 to each of the six graduate programs ($52,500 in total). In accordance with CRA guidelines, a request was sent to each of the department heads requesting a summary describing exactly how the funds are utilized to ensure compliance.

A novel combined silent and live auction was initiated at the CAO/CAOMS 2010 Gala in Whistler BC. Although new to the orthodontists, the oral and maxillofacial surgeons realized prior success through a similar format. The auction raised $2500.00 for the CAO, and plans are in the works for similar events to take place at future galas.

Following an exhaustive search, the CFAO Executive is pleased to announce that Dr. Stephen Roth has assumed the role of permanent CFAO President following his recent retirement from the CAO Board. Please support Stephen as he guides the CFAO to the ‘next level’.

Unfortunately, the recent Alberta issue regarding prolonged treatment duration and financial disclosure has reared its ugly head again. It was thought that there had been resolution following non-response to an inquiry from the Western representative, but alas the dispute is on-going, irrespective of continued non-response. The file on this case may have to close permanently should the complainant not reply in the near future.

Congratulations Dr. Claude Remise For 25 years as head of the Ortho Grad department at the University of Montreal By: Dr. Jean-Marc Retrouvey Claude Remise graduated as a general dentist from the Université de Montréal in 1969 and then spent one year in the Department of Orthodontics as an adjunct professor. Instead of entering the prostgraduate program as planned, the Dean of Dentistry, Dr. JeanPaul Lussier, recommended Claude to the University of Indiana to train under Dr. Charles Burstone.

Dr. Remise values support from Quebec orthodontists to their alma mater. Donations to the department to support research or other commitments that improve the overall educational experience are scarce. According to Claude, when running an excellent clinical department, there remains a Catch-22: Little money, little research; little research, little recognition.

Claude earned a Certificate in Orthodontics and a M.Sc. from Indiana, and then returned to the Université de Montreal as a full-time academic. He was often the only full-time faculty member alongside Dr. Jean Marc Fortin, the interim chairman who himself was part-time.

Dr. Remise is excited about the Department’s move to a brand new nine thousand square foot location. Digital radiography, paperless charting and nineteen new chairs will welcome students and staff in early 2011. In addition, an entire section of the new facility will be dedicated exclusively to clinical research.

In 1974, at the age of twenty nine, Dr. Remise was promoted to chairman of the department, the youngest ever at the Université de Montreal. He was awarded tenure in 1978, stepped down in 1982 and then returned in 1991, where he has been Chair until present.

Dr. Remise is proud of the quality of the clinical education his students receive, encompassing Burstone mechanics, various self- ligating edgewise and SPEED systems, Invisalign, lingual orthodontics and other appliances in order to better reflect the needs of our evolving patient population.

Dr. Remise is the longest-serving active Canadian chairman and should be commended for his commitment to academia.

His dedication to training the best orthodontists is noteworthy. The majority of orthodontists in Quebec have Dr. Remise and his faculty to thank for their excellent orthodontic education. The best of success is extended to the entire department in the upcoming years.

In the 1980’s, Dr. Remise, in conjunction with ten local orthodontists, enthusiastically supported the creation of the Paul Geoffrion Foundation for the advancement of orthodontic education. The Foundation promotes research and presentations to Quebec orthodontists by prominent speakers. The Foundation remains active and provides much assistance with multiple research projects within the department.

Dr. Remise is busy these days promoting multicenter collaboration projects, the latest being a three dimensional cephalometric study with the University of Alberta. Collaboration is a novel initiative that makes the most out of scarce research funds.

Le Dr Claude Remise Claude Remise obtient son diplôme de dentiste généraliste de l’Université de Montréal en 1969 où il passe ensuite une année au Département d’orthodontie à titre de professeur adjoint. Claude prévoit s’inscrire au programme d’études de deuxième cycle, mais, le doyen de la Faculté de médecine dentaire, le Dr Jean-Paul Lussier, lui recommande de recevoir une formation du Dr Charles Burstone de l’université de l’Indiana.

Claude obtient un certificat en orthodontie et une maîtrise ès sciences de l’université de l’Indiana, puis revient à l’Université de Montréal en qualité de professeur à temps plein. Il est souvent le seul membre à temps plein de la faculté en compagnie du Dr Jean-Marc Fortin, directeur par intérim qui, lui-même, occupe son poste à temps partiel.

En 1974, à l’âge de 29 ans, le Dr Remise est promu directeur du département, le plus jeune de l’histoire de l’Université de Montréal. Il obtient sa titularisation en 1978, se retire en 1982, puis est de retour en 1991 et occupe à nouveau le poste de directeur depuis lors.

ment clinique peut jouer un vilain tour : en effet, si on reçoit peu de fonds, on fait peu de recherche et si on fait peu de recherche, on reçoit peu de reconnaissance.

Le Dr Remise se réjouit à la perspective du déménagement du département dans un nouvel immeuble qui s’étend sur 9000 pieds carrés. La radiographie numérique, l’établissement de graphiques sans papier et 19 nouvelles chaises s’offriront aux étudiants et au personnel au début de 2011. De plus, une section entière du nouvel établissement sera consacrée exclusivement à la recherche clinique.

Le Dr Remise est le directeur de département actif qui cumule le plus d’ancienneté au Canada, et son engagement à l’endroit de l’enseignement est digne d’éloges. Son dévouement en vue de former les meilleurs orthodontistes qui soient est notoire. La majorité des orthodontistes au Québec peuvent remercier le Dr Remise et son département de l’excellente formation en orthodontie qu’ils ont prodiguée. Nous souhaitons nos meilleurs vœux de succès à tout le département pour les années à venir.

Le Dr Remise est fier de la qualité de la formation clinique que reçoivent ses étudiants qui porte sur les notions de mécanique de Burstone, divers systèmes d’autoligature, edgewise et SPEED, sur Invisalign, sur d’autres appareils et sur l’orthodontie linguale pour mieux répondre aux besoins de notre population de patients en évolution.

Au cours des années 1980, le Dr Remise, en collaboration avec 10 orthodontistes de la région, appuie avec enthousiasme la création du Fonds Paul-Geoffrion pour la progression de la formation en orthodontie. Le Fonds appuie la recherche et les séminaires qu’animent des conférenciers réputés à l’intention des orthodontistes au Québec. Toujours actif, ce fonds offre une aide considérable à l’appui de nombreux projets de recherche au sein du département.

Ces jours-ci, le Dr Remise s’affaire à la promotion de projets de collaboration entre de nombreux centres, dont le dernier est une étude céphalométrique tridimensionnelle menée avec l’université de l’Alberta. La collaboration est une initiative nouvelle qui tire le meilleur parti des rares fonds affectés à la recherche. Par ailleurs, le Dr Remise s’enorgueillit de sa participation au conseil canadien des directeurs des programmes d’études supérieures en orthodontie et aux réunions de formation qui ont lieu tous les deux ans.

Le Dr Remise est heureux de compter sur le soutien des orthodontistes qui exercent au Québec à son alma mater. Les dons au département à l’appui de la recherche et d’autres engagements qui améliorent le niveau général d’enseignement se font rares. Selon Claude, disposer d’un excellent départe-

Posterboards Abstracts from the 2010 CAO Annual Scientific Session – Part 2 of 2 part series University of Alberta EFFECT OF LOW INTENSITY PULSED ULTRASOUND ON ORTHODONTICALLY INDUCED ROOT RESORPTION: μ-CT VOLUMETRIC ANALYSIS. Author:

Al-Daghreer S*, Doschak M, Sloan AJ, Major PW, Heo G, Scurtescu C, Tsui YY, El-Bialy T.

INTRODUCTION: Low Intensity Pulsed Ultrasound (LIPUS) could potentially be used as an adjunct therapy to arrest root resorption.

AIM: To investigate the effect of therapeutic Low Intensity Pulsed Ultrasound (LIPUS) on orthodontically induced tooth root resorption (OIRR).

MATERIALS AND METHODS: Mandibular fourth premolars were moved bodily in the space of extracted third premolars in five adult beagle dogs in a split mouth design. Continuous orthodontic force of 100 gm was maintained for four weeks.

The test side received LIPUS daily for 20 minutes. Blocks involving the fourth premolar and the periodontal tissue were scanned using Skyscan 1076 Micro-CT imager (resolution of 9 µm). Volumetric analysis was done on blinded reconstructed raw images to measure the volume, number, distribution of the resorption lacunae. The percentage of root resorption was compared to the total root volume.

RESULTS: Volumetric analysis showed a statistically significant difference between the LIPUS and control sides in all variables. The LIPUS side had less resorption volume with a mean difference of 21.6 µm3 (p = 0.041); also the percentage of OIRR was less by a mean difference of 9.95 % (p = 0.029). The total number of the resorption lacunae was less in the LIPUS side with a mean difference of 29.6 (p = 0.035).

DISCUSSION: Daily application of LIPUS for 20 minutes to orthodontically treated teeth had a preventive effect against OIRR without adverse effect on the orthodontic movement rate.

CONCLUSION: LIPUS shows a potential preventive effect against OIRR.

University of Alberta A SURVEY OF CANADIAN ORTHODONTISTS – BUSINESS TRAINING Authors: Mnitimoa M*, Flores-Mir C, Major P, Varnhagen C, Varnhagen S. INTRODUCTION: Orthodontics is a business and business decisions made early in a career may impact the future structure, functionality and profitability of the practice for years to come. Costly mistakes may be made, especially if the pursuit of business knowledge and the organized and intentional development of practice management skills and abilities is not realized prior to the commencement of orthodontic practice.

AIM: The intention of this survey was to explore the business practices and practice management educational needs and perspectives of practicing Canadian orthodontists. The final goal was to explore opinions about how graduate programs may better prepare the newly graduating orthodontists for a successful business career.

METHODS: All orthodontists listed with Canadian provincial licensing boards (except QC) as of late 2009 were contacted and asked to participate in an online survey. The anonymous survey was available at a simplified web address and took 2025 minutes to complete.

RESULTS: A response rate of 19% was obtained (136/713).

Descriptive statistics indicated that the sample may be considered representative of Canadian orthodontists.

DISCUSSION: Canadian orthodontists profiled largely perceived that graduate programs have not adequately prepared new orthodontists for the business aspects of orthodontics.

Many report feeling unprepared for the business challenges experienced in the early years of practice, and a large majority would have preferred a graduate orthodontic program that would have devoted more time to formal business-related training.

CONCLUSIONS: Graduate orthodontic programs should put more emphasis in the preparation for of the business side of orthodontics.

CFAO Graduate Student Posterboards University of Alberta IN VIVO MODEL OF ORTHODONTIC TOOTH MOVEMENT USING MINI-IMPLANTS IN RATS

University of Manitoba THE EFFECT OF CERTAIN DIETARY HABITS ON THE DISCOLORATION OF TOOTH-COLOURED BRACKETS – A PRELIMINARY STUDY

Authors: Kaipatur N*, Wu Y, Major P, Doschak M. Authors: Rykiss J*, Akyalcin S, Wiltshire WA, Rody WJ INTRODUCTION: This study is part of ongoing research to investigate the bone burden effect of bisphosphonate drugs during orthodontic tooth movement.

AIM: The aim of this in vivo animal study is to develop a new model of orthodontic tooth movement using mini-implants as anchorage.

METHODS: Six-month-old SD rats were used with approval from University of Alberta animal care committee. A Stryker 1x3 mm (Stryker Canada, Hamilton, Ontario) self-threading mini-implant was placed in the right maxilla 10 mm from the gingival margin of the right incisor under sterile conditions.

The mini-implant was used to protract the right first molar mesially using a 9 mm NITI closed coil spring for 8 weeks.

Linear measurements of the position of the first molar and the amount of tooth movement was measured using µCT imaging (SkyScan 1076, Kotich, Belgium) at baseline, 4 and 8 weeks. Qualitative and quantitative histology was performed to compare the inflammatory response, bone resorption and osteoclast numbers with untreated left side control.

RESULTS: Results showed 0.75 ±0.01 mm of protraction at 4 weeks and 1.68±0.24 mm at 8 weeks with a statistical significance from baseline at α > 0.05. Although the tooth movement was substantially greater than previous studies in the literature, it was accompanied by mesial tipping of the crown along with intrusion of the mesial and the mesiopalatal roots, more pronounced at 8 weeks in comparison to 4 weeks.

SUMMARY: Tooth-Coloured Brackets are expected to be both aestethically and physically durable during the orthodontic treatment.

Colour change determination may be precisely performed with spectrophotometers; however this technique is time consuming and requires special devices. In this study, the staining properties of six dietary products: tea, tomato juice, red wine, curry, coffee and coke were tested. CIELAB units, which when analysed mathematically, compares the colour parameters of different objects. This system consists of three coordinates L*, a* and b*. The L* refers to the lightness coordinate, and its value ranges from 0 for perfect black to 100 for perfect white, a* is a measure of redness or greenness, and b* is a measure of yellowness or blueness 10 different bracket types were tested (5 plastic, 5 ceramic). In total, 70 brackets were photographed digitally to obtain the baseline L*, a*, b* values. Each sample was immersed in test solutions for one week and the post-treatment images of the test materials were acquired. All L*, a*, b* values including the corrected values of these units were analyzed by a graphic software, and compared between the control and test brackets. Kruskal-Wallis test indicated a significant difference (p<0.05) between the dietary products. Multiple comparisons with Mann-Whitney test indicated that in comparison to the control group (not treated with staining agents) the brackets treated with red wine had the most significant staining characteristics (p<0.05 for all CIELAB units) followed by tea (p<0.05 for a*, b*) and curry (p<0.05 for b*) on the esthetic brackets.

CONCLUSIONS: The results showed that protracted tooth movement could be achieved in small animals using miniimplants.

CFAO Graduate Student Posterboards University of Montreal INFLUENCE OF A FLUORIDE MOUTHRINSE ON THE GALVANIC CORROSION OCCURING BETWEEN NiTi OR CuNiTi WIRES AND ORTHODONTIC BRACKETS: INCIDENCE ON THE MECHANICAL PROPERTIES OF THE WIRES. Authors: Dr David Benguira* AIM: it has been reported that the use of fluoride prophylactic agents can cause galvanic corrosion of the titanium based alloys used in orthodontics. The purpose of the present study was to investigate the effects of a fluoride mouthrinse on the mechanical properties of nickel-titanium (NiTi) and copper– nickel-titanium (CuNiTi) orthodontic archwires that have been coupled with different types of orthodontic brackets (Smartclip, Clarity, and Sprint brackets).

MATERIALS AND METHODS: 90 segments of NiTi and 90 segments of CuNiTi archwires were tested. Every segment was coupled with 2 brackets of each brand. The wire–bracket assembly obtained was incubated, at 37°C for three hours either in a solution of a commercially available mouthwash (Fluorinse™ 0,05% NaF), or in a solution of artificial saliva (control).

A 3-point bending test was made to calculate the loading and unloading elastic modulus and yield strength of the wires.

Analysis of variance (ANOVA) and post hoc comparisons were made using Bonferronni’s correction to identify the statistically significant differences (α = 0,05).

RESULTS: The use of a fluoridated mouthrinse reduced the loading and unloading elastic modulus and yield strength of the NiTi wires. This reduction, however, varies with the type of bracket that was coupled with the wire.

The mechanical properties of the CuNiTi wires were not modified by the use of the fluoride rinse or by the type of bracket to which they were coupled.

CONCLUSIONS: The use of a fluoride mouthrinse alters the mechanical properties of NiTi wires only. This effect varies with the type of bracket that was in contact with the wire. However our results do not allow us to conclude that the alteration of the mechanical properties of the wires would necessarily imply a prolongation of the orthodontic treatment time.

KEY WORDS: Fluoride, nickel-titanium archwires, galvanic corrosion, mechanical properties.

Following the incubation, the wires were separated from the brackets, rinsed, mounted on a stainless steel support and placed in a waterbath of artificial saliva at 37°C.

CFAO Graduate Student Posterboards University of Montreal CLINICAL DIFFERENCE BETWEEN THE NASAL AND FACIAL CPAP MASKS IN THE TREATMENT OF OBSTRUCTIVE SLEEP APNEA. A PILOT STUDY.

University of Toronto NEUROPLASTICITY OF THE FACE MOTOR CORTEX (FACE-M1) ASSOCIATED WITH ORTHODONTIC TOOTH MOVEMENT OF THE RAT TEETH

Andree Montpetit*

INTRODUCTION: The first line of treatment for obstructive sleep apnea is continuous positive airway pressure or CPAP used a via nasal mask. Some patients, unable to tolerate the nasal mask, have to turn to the facial mask, which sometimes requires a superior level of pressure to eliminate all the respiratory events. We believe that the force applied on the chin from a tight adjustment of the facial mask may retrude the mandible and diminish the upper airway caliber.

OBJECTIVES: Our objectives for this study were to: 1) demonstrate that a difference of effective therapeutic pressure between the nasal and facial masks does exist, 2) quantify the leaks associated with each mask, 3) evaluate the effect of a neutral mandibular appliance (NMA), that prevents the retrusion of the mandible, on the effective pressure of both masks and 4) evaluate if a link between the cephalometric values and varied individual responses to both masks exists.

METHODS: Eight subjects (2 females, 6 males) mean age 56.3 years (33-65y) participated in the cross-over design pilot study. All subjects underwent a complete orthodontic examination including lateral cephalometric radiograph before spending two nights in a sleep laboratory for a polysomnography in split-night protocol, where both mask were worn alone on the first night and with the NMA on the second night.

RESULTS: We found that the therapeutic effective pressure was higher with the facial mask compared to the nasal mask, and this difference was statistically significant. The leak was more elevated with the nasal mask, thus eliminating this factor as a probable cause of the higher pressure with the facial mask. The NMA did not have any statistically significant effect on both mask; however a possible positive effect might be seen with the inclusion of the Bi-level PAP pressures.

CONCLUSION: Our results cannot confirm the role of the retrusion of the mandible, caused by the force applied by the facial mask, in the necessity of a superior level of pressure with that mask, but we cannot eliminate that possibility either. Our results suggest that this phenomenon is more frequent that we may think and that a link with some anatomical factors may exist.

The aim was to determine if altering the rat’s dental occlusion with an orthodontic appliance produces changes in the features of the ICMS-defined face-M1. Sprague-Dawley rats had a closed-coil spring placed to mesialize the right upper molars. Pairs of stainless-steel EMG electrodes were implanted in the left and right anterior digastric (AD –jaw-opening), masseter (jaw-closing) and genioglossus (GG – tongue-protrusion) muscles. Intracortical micro-stimulation (ICMS - 20, 40, 60 μA; each of 5 trains at 1 Hz.) was applied through transdural tracks to the right and left face-M1 in rats on days 1 (n=5), 7 (n=5), and 28 (n=5) after the active spring was attached to the teeth. The control group was the naïve group (n=5) and sham groups with springs with no activation for days 1 (n=3), 7 (n=4), and 28 (n=5). Intracortical microelectrode penetrations had a horizontal spatial resolution of 0.5 mm, and at each anteroposterior plane (AP) a series of mediolateral (ML) penetrations were made with each penetration being 0.2 mm increments in depth. A significant reduction in the total number of AD and GG positive sites occurred on day 1, which recovered to naïve level by day 7, followed by another significant reduction that was evident at day 28.

University of Toronto PERCEPTIONS OF PLASTIC SURGEONS, ORTHODONTISTS AND LAYPERSONS TO ALTERED FACIAL BALANCE Authors: Marcy SD* 1, Taylor HO 2, Clausen A 2, Semple JL 3, Tompson BD1, Forrest CR 2 BACKGROUND: It is well established that mild facial asymmetry is considered normal, and it is thought that a few millimeters or degrees of difference between left and right sides of the face is not clinically appreciated.

OBJECTIVE: To quantify in precise physical units the acceptability of facial asymmetry to plastic surgeons, orthodontists and the lay population.

METHODS: Stereophotogrammetric images were animated with one of six facial asymmetries, including: jaw and nasal deviation, interocular distance, ocular height, angulation, and

CFAO Graduate Student Posterboards shape. Twelve animations were randomly presented, and 60 evaluators were asked to judge the faces based on their visual acceptability using an interactive flash application.

RESULTS: The results demonstrated threshold levels of acceptability for each regional facial asymmetry. Mandibular deviation of approximately 4 mm was necessary to be judged as unacceptable. Nearly 3 degrees of nasal deviation was considered unacceptable. Approximately 9% rounder and 18% flatter eye was considered unacceptable. Hypertelorism was unacceptable after an increase of approximately 2 mm and hypotelorism unacceptable after a decrease of approximately 2.5 mm. Vertical ocular dystopia was unacceptable after superior positioning of approximately 2.5 mm and inferior positioning of approximately 2 mm. Threshold levels for unacceptable ocular angulation were approximately 5.5 degrees superiorly and 3.5 degrees inferiorly.

CONCLUSIONS: The results of this study show that plastic surgeons, orthodontists, and lay people find specific facial asymmetries to be unacceptable at similar levels of deviation.

The quantification of asymmetric thresholds may aid the clinician in diagnosis and the evaluation of treatment results.

University of Western Ontario IN VITRO COMPARISON OF TWO SELF-ETCHING PRIMERS USING AN INDIRECT BONDING METHOD Authors: Leung S*, Foley T, Rizkalla A, Banting D, Mamandras A

INTRODUCTION: Indirect bonding allows brackets to be positioned more accurately and decreases clinical chair time. Another step in the bonding process that decreases chair time is the use of a self-etching primer (SEP). There is a paucity of information in the literature regarding how indirect bonding in combination with an SEP affect bond strength.

PURPOSE: To determine if there is a difference in shear bond strength (SBS) between two SEP products (3M Transbond Plus SEPTM, Reliance SEPTM) in an indirect bonding method, compared to an indirect bonded conventional acid etch (AE) control and a direct bonded AE control.

MATERIALS AND METHODS: One hundred ninety two human bicuspids were arranged in acrylic bases mimicking human arch forms, with four arches per group. Teeth were bonded, stored for 30 days, thermocycled and debonded with an Instron universal testing machine. Using light microscopy, a modified Adhesive Remnant Index (ARI) was used to de-

scribe mode of bracket failure and presence of enamel fracture (EF).

RESULTS AND CONCLUSIONS: The mean SBS value for all groups was above an accepted minimum value required for orthodontic treatment. Significant differences were found (p<0.5) among the four groups. The direct bonded AE control group had significantly higher bonds strengths than the other three indirect bonded groups. The distribution of ARI scores among the four groups was not significantly different; all groups experienced mainly cohesive bond failures. The incidence of EF was highest in the direct bonded AE group and the other three groups had a similar number of enamel fractures.

University of Western Ontario AN EVALUATION OF NOVEL APPROACHES TO ANTIMICROBIAL CONTROL OF ORAL BIOFILMS Authors: Jindal M*

INTRODUCTION: Streptococcus mutans (SM) and Haemophilus actinomycetemcomitans (HA) are important pathogens in the development of caries and periodontitis. This thesis investigated several novel strategies aimed at preventing their growth and biofilm forming capacity.

METHODS: SM and HA biofilms were challenged with numerous antimicrobial solutions and assessed for biofilm retention and bacterial survival. Antibiotic susceptibility profiling was performed and the ability of antimicrobial-impregnated silicone disks and Streptococcus salivarius probiotic strains K12 and M18 to inhibit the pathogens was investigated.

RESULTS: Silicone oil effectively disrupted HA biofilms but did not affect either pathogenâ&#x20AC;&#x2122;s viability. Neither HA nor SM showed any relevant antibiotic resistance and polyvinyl siloxane impregnated with triclosan and chlorhexidine demonstrated antibacterial activity against both strains. Finally, both probiotics inhibited the growth of HA but not SM via differential antagonism.

CONCLUSIONS: This work supports the widening application of silicone-based products and probiotics in maintaining oral health and fighting disease.

The 2010 CAO Annual Scientific Session held last September in Whistler, British Columbia was a success with over 700 registrants enjoying the local surroundings.

The 2011-2012 Executive of the Alberta Society of Orthodontists (ASO) includes Immediate Past-President Mike Bleau, President Cory Liss, Vice-President Warren Cohen, and Secretary-Treasurer Ivan Hucal.

The BCSO media campaign was launched in August and September 2010 with advertisements in two editions each of Canadian Living, BC Parent (Back to School Edition) and Macleans magazines.

The Annual Scientific Meeting of the ASO was held in Banff on March 4th and 5th, 2011. It was well attended and featured Dr. John Graham who gave a brilliant presentation on a variety of pertinent topics including TADs and 3D CBCT.

The College of Dental Surgeons of BC has designated Align Technology’s use of Elite, Premium or Preferred Provider status inappropriate. A letter was sent outlining how the terms were contrary to the CDSBC bylaws and requesting modification. Registrar Heather Mackay noted that the College will notify practitioners regarding improper corporate designation.

The ASO is planning on having the Society’s website hosted by the CAO and is currently working with LS Graphics to get this up and running.

A task force has been established by the BCSO to establish a mentorship program for new orthodontists, chaired by Dr. Lun Wang. The task force, composed of Amanda Mapplethorp, Jordan Miller and Robert Eliot held its inaugural meeting February 22nd, 2010.

The CDSBC became legislated under the Health Professions Act of BC in April of 2009 permitting the public increased recourse when filing formal complaints against practitioners.

Malpractice coverage is applicable at the initial dispute but should the complainant seek recourse through the College or the Health Professions Act, malpractice insurance will not fund the additional associated legal costs. Additional insurance is available through CDSPI.

The ADA&C Infection Prevention and Control Standards have been finalized for full implementation by January 2012. Although there have been concerns raised regarding the impact of these standards on orthodontic practice in Alberta, no specific issues have been brought forward to date. The ADA&C has released a draft of standards for use of CBCT, however the ASO may request a revision of the restrictive draft document. The ASO has formed a ‘CBCT Guidelines’ committee to look closely at the standards and to formalize a response if necessary.

The ADA&C met in February to address the issue of advertising regulations as it relates to the Code of Ethics, particularly with respect to the use of CAO and AAO references in advertising. The ASO has formed a committee to further look at this issue, and for the time being has deferred the potential retention of legal counsel until the ADA&C has had a chance to revisit this issue.

The graduate orthodontic program at the University of British Columbia accepted its first three three-year Masters students in August of 2010. The BSCSO annual general meeting is Friday, June 10th, 2011 at the UBC Golf Club. The PCSO Annual Scientific Session is in Vancouver, September 23rd to 26th, 2011.

The annual meeting of the Saskatchewan Society of Orthodontists was held in Saskatoon in October, 2010. Howard Steiman made his presidential debut and it was a pleasure to host him. A donation to the CFAO was made in his honour for making the long trip out.

Orthodontists have tried to withdraw from the First Nations Health and the claims service through ESI program however difficulties were encountered in that patients currently in and approved for treatment were subsequently denied payment.

The SSO is still unable to obtain answers from ESI as to what their policy is on providers withdrawing from their program and how it affects existing patients.

The next SSO meeting is October 21st, 2011 in Saskatoon sponsored by GAC featuring Dr. Bob Fry for doctor/staff continuing education.

The fall Manitoba Orthodontic Society (MOS) dinner meeting was held on October 28, 2010.

A recent concern among Manitoba orthodontists has been the significantly lower fees paid by NIHB for orthodontic care of First Nations patients in Manitoba in comparison to the other provinces. Last fall, NIHB revised the fee for orthodontic treatment to $5,168.00 up from $4,970.00.

Upon approval, total fees paid for an orthodontic exam, records and treatment is $5,464.00. Terry Hupman of NIHB explained that the NIHB fee represents approximately ninety percent of the average orthodontic fee in Manitoba. Despite the modest increase in NIHB fees, there are still concerns regarding a lack of concrete criteria for case acceptance and the low rate of acceptance overall.

The MOS by-laws are still in development in preparation for affiliation with the AAO.

The Ontario Public Awareness Campaign is into its second year following a $300.00 assessment of each active member. The campaign has an additional assessed year in 2012. The objective of the campaign is to educate patients about the difference between general dentists and orthodontists and to direct traffic to the OAO website (/www.oao.on.ca/). The campaign is focusing on electronic media, such as online banner advertisements and search engine marketing to get the message out.

The Ontario Dental Association (ODA) and the Canadian Dental Association (CDA) are officially affiliated. Ontario dentists who are/become ODA members are now obligated to become members of the CDA. The moratorium on the purchase of Cone Beam Computerized Tomography (CbCT) by dentists will be lifted later this year. Prior to purchasing a CbCT unit or to a retrofit, the dentist will be required to successfully complete a two day didactic course, and a half-day practical course and an examination. The course was offered for the first time in January 2011 by the University of Toronto and was attended by sixtysix dentists (including yours truly). Regulations require that a written report accompany each 3D CbCT image made by the dentist.

Atlantic Report Dr. Dan Stuart [Email: danstuart96@hotmail.com] The Atlantic Orthodontists Association (AOA) held its Annual General Meeting in Halifax on May 14th, 2010. Howard Steiman, then the CAO President-Elect was in attendance on behalf of Gerry Zeit, then CAO President. How lucky is Dr. Steiman that he gets to return to the Atlantic Provinces as President for our Annual General Meeting this year at the Fox Harbor Resort and Spa, located in Wallace, Nova Scotia on June 24th-25th, 2011? Designed to be a retreat for doctors and spouses, there will be a golf tournament, cooking lessons, skeet shooting, kitchen party with a live band and continuing education with Dr “Wick” Alexander. The weekend is shaping up to be a great time for all.

The AOA is getting ready to incorporate this spring and will sign the AAO affiliation agreement, but following advice from legal counsel, will delay signing until new regulations for the incorporation of nonprofit organizations are available.

The current slate of officers for the AOA includes Past-President Stephen Roth who agreed to return as Secretary/Treasurer, Don Johnston the current Vice-President and also the component representative to NESO and Brien Stackhouse who is a member of the Executive as a recent Past-President.

Remember that the CAO Scientific Session is September 23rd to 25th in Halifax, Nova Scotia. Have you ever raised your glass and yelled “sociable!” to great live music? If not, maybe it’s high time that you did. Come out and enjoy fabulous seafood, a city rich in history, and a guaranteed enjoyable meeting.

Straight Shooters 1. Why is the orthodontist from Bolton (Ontario) so lonely?

He’s just not a good fit.

2. What happened to the orthodontist after he was arrested?

He was scared straight.

3. What advice do you give someone before going to see an orthodontist?

Brace yourself! (courtesy of Racquel Posluns)

Six Degrees Ain’t All About Torque!

If you’re Canadian, you’ve had this conversation with someone you’ve just met.

“So. You’re from Canada. Do you know (insert name here)?”

In due time, perhaps, this question may be answerable. The world is getting smaller. Folks jet to Europe for the weekend at the mere mention of a seat sale.

We talk, nay text, to multiple contacts at once, whenever something as insignificant as work doesn’t get in our way.

And of course there is Facebook, the Grand-Daddy of world domination.

Yeah, I’ve seen the movie (twice). I’ve gone on-line to check it out. Heck, I’ve even tried to set up an account for myself. Yet, in spite of my best efforts, I still can’t get a handle on it. But that was until a patient pointed out that you need ‘friends’ to make it all work. Suddenly the answer seemed so clear. Oh, how I miss the good old days of MSN messenger (b. 2001, d. 2005).

Until the day we are born with a SIM card imbedded deep within our anatomy, good or bad, the general public will remain a collection of individuals and the answer to the aforementioned question will continue to be a polite “Um. No. Sorry. Canada is big place”.

That is, unless you are an orthodontist.

It never ceases to amaze me the web of communication that exists between orthodontists. Take two wire-benders from

opposite ends of the continent, give them a drink and give them the green light to gab. Within moments a connection will be made where someone knows someone who went to school with soand-so, only to discover that they were twins separated at birth. My grandmother called this phenomenon ‘Jewish Geography’; I am certain similar terms apply to the hundreds of cultures that exist from Beijing to Barcelona. Will Smith and Donald Sutherland brought the concept to life in the film Six Degrees of Separation. Maybe in orthodontics, we should give it a similar snappy name like ‘Separator- Separation’ or ‘Torque Talk’: Or maybe it’s time to simply provide a few choice examples of what I speak.

Last December Bruno, my partner-in crime and I had the good fortune to travel to Wisconsin to see the as-yet-uncrowned 2010 Superbowl Champion Green Bay Packers play the San Francisco 49ers. Along the way, we met up with a group of orthodontists from Louisiana and California. In total, there were probably close to fifteen of us sitting around the dinner table. Bruno started talking with Buzzy and Buddy (no relation) from the Deep South.

Within moments, they were sharing stories about the characters they all knew at Louisiana State University where Buzzy and Buddy had graduated in the ‘70’s and where Bruno had spent some time prior to orthodontics. Three men separated by thousands of kilometers with an unbeknownst bond made apparent the night before an NFL football game in Middle America; kind of surreal when looking from the outside in.

I was at that dinner too. I turned to the new graduate to my right and after the usual pleasantries, he let on that he was interested in practicing close to where my relatives live in California. Dig a little deeper and it turns out, in three days, this nice young man was going for an interview with the orthodontist who treated my cousins in Los Altos, in the same office where my Aunt once worked as a receptionist. Totally weird.

It was then I thought I heard Rod Serling’s voice in my left ear but it in reality it was just the waiter inquiring if I had enough to drink.

It doesn’t end there. A few months later, I was in San Francisco and met up with a friend of mine who teaches full-time.

She introduced me to John, who turned out to be a classmate of Kevin, who is Bruno’s best friend. This is beyond coincidence. This is more than close. This is getting creepy.

As technology continues to shrink the big blue marble we all call home, orthodontists can take pride in being, once again, ahead of the curve. There are connections within our profession that surpass the strength of Silane, the complexity of Cross-Link and the frequency of Forsus. And while it may be getting a little too close for comfort, isn’t it, deep down, kind of fun? You know it is!

So, the next time you are at a meeting and someone asks you if you know (insert name here) from Canada, odds are, if you are an orthodontist, you probably do.

Or at least you know somebody who does.

Have a wonderful summer y’all.
