AN AESTHETIC AND BIOMIMETIC APPROACH WITH A GLASS HYBRID FOR DIRECT RESTORATIONS

The overall goal of this article is to provide the clinician with an overview of the information on a newly developed glass hybrid system (EQUIA Forte® HT) and as well as to give useful application tips based on results from clinical cases.

What differentiates glass hybrid from other conventional GI restoratives is its chemistry. The highly reactive fluoro-alumino-silicate (FAS) micronsized fillers (<4 μm) were added to the standard FAS glass filler particles of EQUIA Fil. The micron-sized filler particles release more metal ions, which improve the cross-linking of the polyacrylic acid matrix and the overall physical properties.

Additionally, EQUIA Forte HT Fil liquid comprises a high-molecular-weight polyacrylic acid, which helps to improve the chemical stability, acid resistance, and physical properties of the set cement.

The light-cured, nano- filled resin coating (EQUIA Forte Coat) was improved by incorporating a reactive multifunctional monomer that increases resistance to wear, has a higher polymerisation conversion and thinner film layer, and also provides a smoother surface to the final restoration.

EQUIA Forte® HT was used in a 34-year-old female patient for the emergency treatment of a vital lower first molar (tooth 36) with a deep, large carious lesion (Fig 1a). The vitality of the tooth was first determined by pulp testing and a radiograph was taken to check the depth of the lesion (Fig 1b).

Local anaesthesia was applied and caries was removed using tungsten carbide burs (Busch "AU" Carbide Burr - TF1AU). Infected dentine was removed with an excavator (Fig 1c). The cavity walls were cleaned with 20% polyacrylic acid (Cavity conditioner, GC) for 10s (Fig 1d), rinsed thoroughly with water (Fig 1e) and dried gently (Fig 1f).

EQUIA Forte® HT capsules were prepared and mixed for 10 s, then restorative was directly applied into the cavity in a sufficient quantity using a bulk-fill technique with a special applicator (Fig 1g). EQUIA Forte® HT was condensed against the cavity with a plastic hand instrument and was allowed to set undisturbed for approx. 2.5 min (Fig 1h). This restorative does not require a special surface coating during the setting reaction.

The finishing process was performed with the use of rotary instruments in 2 steps: a) tapered trimming & finishing tungsten carbide burs were used for forming the fissures and occlusal anatomy of the restoration; b) flame-shaped rubber points (blue and gray) were used for polishing (Fig 1i). All burs and polishers were used under water irrigation to avoid over-drying the restorative. The occlusal contact points were checked (Fig 1j).

A final layer of the coating agent (EQUIA Forte® HT Coat) was applied on the surface of the restoration without air- blowing (Fig 1k), then it was light-cured for 20 s with a D-Light DUO LED curing device at 1400 mW/cm2 (Fig 1l).

The final clinical and radiographic views of the restoration are shown in Figures 1m-o, demonstrating excellent contour and aesthetics.

PLAY IT SMART WITH EQUIA FORTE HT

What is SMART?

SMART or Silver Modified Atraumatic Restorative Treatment involves the application of Silver Diamine Fluoride (SDF) followed by a restoration with self-adhesive, long-term restoratives such as glass hybrids.

Why SMART?

SDF typically requires repeated applications over multiple appointments to be effective. However, compliance may be a factor for many patients, and others may not have regular access to care. In SMART, SDF arrests decay while glass-based restorations help hide stains and provide an excellent seal to protect against further decay.

What are the benefits of SMART?

• Minimally invasive approach conserving pulp

• Hand instruments or slow speed drill can be used to reduce aerosols

• Reduced anxiety or phobia associated with drill or local anesthesia

• Rechargeable fluoride release for help protect against recurrent decay

• Ideal treatment for pediatric, high-risk caries and geriatric population

How many appointments are needed?

SMART can be accomplished on one or two appointments. The two-appointment treatment may provide a better esthetic outcome.

KATANA CLEANER

A PRODUCT REVIEW FROM DR. ALFRED DELA CRUZ FOR DENTAL PRODUCT SHOPPER

The first and only zirconia cleaner indicated for both extraoral and intraoral use, KATANA Cleaner thoroughly cleans the surfaces of restorations in only 10 seconds.

As a stickler for detail, Dr. Alfred dela Cruz is well aware that the ultimate success of any restoration depends upon careful attention to each and every step in the process. It’s for this reason that, always alert to the possibility of debonding, Dr. dela Cruz typically takes an extra 5 minutes to clean his zirconia crowns in an ultrasonic bath of distilled water after air abrasion. Hoping to save time, Dr. dela Cruz agreed to try a new product, Kuraray’s KATANA Cleaner, that eliminates the ultrasonic bath step without sacrificing bonding.

What sets this non-abrasive cleaner apart from other cleaning agents is not only its proprietary chemistry, which improves bonding by maximizing cleaning efficacy, but also its mild pH, which makes KATANA Cleaner the only such cleaner formulated for extraoral cleaning of prosthetic restorations and for intraoral cleaning of prepared tooth structure.

After using KATANA Cleaner for several weeks for the DPS review, Dr. dela Cruz is thrilled to have an extra 5 minutes to spare and said, “KATANA Cleaner prepares crowns for a solid cementation or bond,” and those crowns “bond a lot better after trial fit contamination.”

Ease of Use: Application & Handling

Described by Kuraray as “the easy way to optimize bondings,” KATANA Cleaner features a flip-top cap that enables one-handed opening, and the material is purple in color to ensure optimal visibility during placement and cleanup. Formulated with a viscosity for easy placement and handling, KATANA Cleaner requires only 10 seconds of rubbing to thoroughly clean the surface.

Several evaluators described the cleaner’s ease of application as their favorite feature, including Dr. Robert Wilkoff, who said KATANA Cleaner “didn’t spread or leak excessively and was easy to rinse off the crown’s intaglio.” Dr. R.J. Sondkar praised the “ergonomically designed bottle/dispenser that allows single-hand usage.” Several evaluators mentioned the cleaner’s purple color, including Dr. dela Cruz, who said, “It is easy to see and easy to rinse, and [the color] makes it easy to distinguish where it’s placed on intaglio surfaces.” Dr. Steven Berk also called KATANA Cleaner “extremely easy to see where it was placed due to its purple color,” and Dr. James DeFilippo described it as “quick and easy” to use but said he would have preferred a bit more viscosity.

Cleaning Effectiveness

KATANA Cleaner is formulated with proprietary surface-active MDP salt, which greatly enhances cleaning efficacy. “It is a well-made product that is an effective cleanser and is simple to use and predictable,” said Dr. Sondkar. “It helped improve cleaning the crowns before cementing,” shared Dr. John Rezaei, and Dr. DeFilippo explained, “It helps clean any matter that accumulated inside the crown or abutment while trying it in and making adjustments.” Calling KATANA Cleaner “very effective in eliminating the smear layer,” Dr. Berk added, “I have been using it to seat zirconia crowns and have had good results so far.” Commenting on an additional benefit, Dr. Edward Kusek said that his patients “did not have any sensitivity with its use.”

Bonding & Versatility

KATANA Cleaner’s versatility is two-fold. Its mild 4.5 pH value sets it apart from other cleaners by enabling both extraoral and intraoral use, and it effectively cleans virtually all contaminated restorative materials (glass ceramic, zirconia, resin, metal, fiber posts, and implant abutments) and prepared tooth structures (dentin, enamel, root canals, and tooth abutments).

Concerned about the prospect of debonded crowns, Dr. Wilkoff told DPS that KATANA Cleaner “appeared to work as well as or better than the competitors,” although he acknowledged the need for 1-2 years of use for a thorough evaluation. Also commenting on the need for long-term evaluation, Dr. DeFilippo said that KATANA Cleaner “handles well and appears to work well.” Noting that he used the cleaner on zirconia onlays prior to bonding, Dr. dela Cruz shared, “I will track any that come off after using this, but I doubt that will happen.”

KATANA Cleaner is unique in its ability to clean restorations both intraorally and extraorally, which was appreciated by the evaluators. Glad that he found a product that adequately cleans the tooth surface or restoration prior to cementation, Dr. Sondkar said he “used KATANA Cleaner in multiple clinical restorative scenarios with consistent satisfaction.”

Overall Satisfaction

Impressed with the ease of use and efficacy of this all-purpose universal cleaner, the evaluators deemed KATANA Cleaner to be a DPS Best Product. Dr. Michael Tarighati summed up his experience with the cleaner by describing it simply as “overall, a great product.” And Dr. dela Cruz concluded, “I am confident in the long-term prognosis of zirconia crowns luted after using KATANA Cleaner.”

Takeaways

• The only zirconia cleaner formulated for both extraoral and intraoral cleaning

• Proprietary surface-active MDP salt enhances cleaning efficacy

• Requires only 10 seconds of rubbing

• Flip-top cap enables one-handed opening

• Purple color ensures optimal visibility during placement and cleanup

GETTING SMARTER ALL THE TIME

Assisted intelligence is the key ingredient fuelling many of the advancements in the dental practice—from cutting-edge digital imaging to all-in-one software solutions like DTX Studio™ Clinic from DEXIS. Although it will never replace clinical experience and expertise, intelligent technologies are creating opportunities to assist with diagnosis, treatment planning, and more.

In recent years, artificial intelligence, or AI, has become so ingrained in our daily lives that we often don’t even realise it’s there, working in the background. So, what exactly is AI? Simply put, it’s intelligence demonstrated by machines. AI is built to mimic the human mind, combining computer science and robust datasets to enable problem solving and decision making. AI is fuelled by algorithms, which are essentially the rules for problem solving. Today, AI is not only automating machinery; it’s the technology behind your search engine results, the product recommendations you receive while scrolling through social media, and the speech recognition systems you use every day.

features that improve both practice efficiencies and patient outcomes, it’s imaging software like DTX Studio Clinic that brings it all together. Every image, whether 2D, 3D, clinical photography, or intraoral scans, is housed in this solution. Any technology you buy comes with its own software, but it can be cumbersome to switch back and forth to get what you need from each one.

This solution ties everything together, making it accessible via a single, intuitive software.

DTX Studio Clinic makes it easy to integrate digital diagnostic and treatment planning processes into the workflow, from image collection and image capturing to treatment planning and delivery

It’s clear AI has a huge impact on our daily lives, so it’s no surprise it’s starting to play a major role in dentistry as well. The AI algorithms can direct software to point out if information is missing on a scan, for example, or digitally select the appropriate tooth shade for a case. Of course, no matter the application, human input is still required; AI will never replace clinicians and their teams. For this reason, AI can be considered “assisted intelligence” technology, helping you arrive at informed decisions so you can better diagnose and treatment plan.

While dental equipment is evolving to include smart

Improving Communication

Dentists can use the software to boost patient education and ultimately case acceptance. Presentations become more robust, with patients able to see all the relevant images on the screen in front of them as you go over the treatment plan. They leave with a much better understanding of their condition and why you’re recommending treatment, making them more likely to move forward.

The intuitive software also enhances communication between dentists and their team members. For example, it’s easy to sync data across rooms or practices with 40 installations per licence; all team members have quick, easy access to the same information.

An Enhanced Workflow

With DTX Studio Clinic, AI is present throughout the workflow and serves as a digital assistant. The DTX Studio Clinic Smart features were designed together with dentists around the world to improve the way you diagnose and communicate with your patients. Through MagicSort™, for example™, the software automatically recognises tooth numbers and orders intraoral images. Images are then correctly orientated and placed into the relevant position in your selected radiographic mounts, eliminating a task once handled manually. SmartFocus™ instantly brings up the entire 2D and 3D imaging history of whichever tooth you choose to click on the screen. SmartFusion™ combines surface models from intraoral and desktop scanners with any CBCT scan via proprietary voxel-based algorithms, providing clinicians with an accurate 3D view of surface details and the underlying anatomy. The software also automatically tracks mandibular nerve canals and identifies airways, removing manual labour and uncertainty for the clinician. 2D dental findings allows you to instantly detect and diagnose six potential pathologies in 2D intraoral x-rays.

Simplified Image Acquisition

Direct acquire from your imaging devices through DTX Studio Clinic on Windows® PC and Mac®. This includes CBCTs, Pans, Cephs, intraoral optical scanners, intraoral X-rays, intraoral cameras, diagnostic cameras and importing clinical photos. Easily import industry standard file formats, such as DICOM, STL, PLY, bmp, jpg, png, from your 2D and 3D devices or open DTX Studio Clinic from your Practice Management System and never have to enter patient data twice.

GoShare™ - Encrypted Data Sharing

DTX Studio Go is an online data transfer portal to facilitate secure external collaboration. Share your patient’s data with a connected lab, specialist, referral dentists or other colleague for smooth case collaboration. DTX Studio GoShare offers monthly data transfer allowance from 3-30GB so you can efficiently request design and production services and effortlessly share the needed imaging data directly from your patient library. With an open output path, you can also export files for in-house printing and production.

Putting It All Together

DO WE NEED A “NEW” RUBBER DAM

INTERVIEW WITH DR. MARIO ROMERO

Interview done in November 2022

We have been isolating in Dentistry for over 150 years so we have plenty of options in regards to rubber dams out there in the market.

Do we need a new one?

I personally think that this one hit the jackpot. Why?

#1 The Color black: very good contrast

#2 Very important personally to me, is made out of latex, very resistant and actually helps with retraction so for me this really a game changer in the market.

What are the key features of the Hysolate Dental Dam?

Well, the key features of the isolate dental dam, I think, they are the most important ones are non-powdered and low protein. And the reason why this is important is because we are all afraid of using latex in our office because we think that it is going to create some hypersensitivity reaction on our patients. Taking away the powder and having low protein, it’s going to reduce substantially the risk of hypersensitivity for our patients, so for me, those are the most important key features, but I ‘m going to mention a third one I thought, because I always get this question: how precise are we when we are guessing where we need to puncture our rubber dams to actually isolate? Well, this one takes all the guesswork away because it’s pre printed so we are going to know exactly where to perforate the rubber dam for an ideal isolation every single time.

Do you want to know more about:

• How could the non-reflective properties benefit other specialties?

• How could this benefit dental photography?

• Any other shared tips?

AN INTERVIEW WITH DR. CHARLES J. GOODIS

FOUNDER AND

CEO

Henry Schein has been offering the endodontic solutions portfolio of EdgeEndo®, one of the world’s largest NiTi rotary file suppliers, with EdgeFile® X7, the number one selling EdgeEndo® NiTi system in the United States.

EdgeEndo® is conducting business in 35 countries around the world. The company’s mission is to deliver high quality dental products and solutions at affordable prices which in turn benefits practitioners and patients everywhere.

US based Endodontist, Dr. Charles J. Goodis, Founder of EdgeEndo®, received his DDS from the University of Michigan, his GPR residency at the University of Minnesota, and his Endodontic residency at the University of Connecticut. Dr. Goodis has dedicated his career to constantly improving the root canal procedure. His findings led him to create more effective root canal instruments and procedures. He’s been working as an endodontist in Albuquerque, New Mexico, USA for 25 years.

Dr. Goodis, you are a dentist and years ago you decided to start your own company that, among other things, develops NiTi files for root canal preparation. Please tell us something about the company and the main products. My background in mechanical engineering and training in endodontics, as well as trying to help the patient and dentist do the best they can, inspired me to found EdgeEndo. Edge has been in the US market since 2012. In this short time, we have become one of the largest endo companies in the world. We now offer our products in 35 different countries.

Our main products are NiTi files that are heattreated through our proprietary FireWire process. Our best-selling system is the EdgeFile X7. It’s one of the leading files used by endodontist in the US, Canada, New Zealand, Australia and many countries in the Middle East. EdgeTaper Platinum and EdgeOne Fire have also been very successful systems in these markets. EdgeEndo has been well received in the industry. In addition to files, we also sell a full assortment of accessory products including gutta percha and paper points.

What are the benefits of the EdgeEndo files and which endodontist will benefit mostly from these files?

The patient of course wants a quick root canal procedure because any time you can reduce chair time, they appreciate. And the patient wants a precise root canal clean-up to get rid of the pain but preserve the tooth. Both is supported by the flexibility paired with the stability, our files provide and thus allow endodontists to perform an accurate and fast procedure. In addition, the reasonablypriced files make the treatment also more efficient in respect of costs.

How do you achieve the balance between offering high-quality endodontic products at low price?

Quality and value are paramount in importance at EdgeEndo. We have a very detailed quality system that allows us to produce a consistent, high quality product. Unfortunately, being an endodontist treating patients, I saw how high costs are and I thought to myself we can still offer a great product at a good price which provides value for the money.

I think reasonable prices are important to a dental practice because as the dental fee structure changes in the US some dentists are making less money than they did before, and I believe offering a high-quality instrument at a lower price really helps dentists succeed.

Which is the most important instrument for rootcanal preparation? How many files does one require as a rule?

My personal preference is EdgeFile X7, it is super flexible, efficient and unbelievably strong. Each system varies somewhat. As a rule, most root canals can be completed with between 1 and 3 files. We’ve simplified the technique for systems to help the dentist and eliminate waste. As an endodontist, I never used all of the different sizes in an assortment pack. With my file systems you can purchase the files needed and follow the techniques we’ve worked on with other dentists to develop.

A common concern within root canal preparation is the cyclic fatigue. How resistant are the EdgeFiles (perhaps with reference to a clinical study)?

Our file systems are very resistant to cyclic fatigue. We’ve done both internal and 3rd party peer reviewed testing to ensure our files are more resistant. Dentist can refer to all of the published research on our site that back up our claim (https:// web.edgeendo.com/studies/).

What if I already have a working system and technique? Are the EdgeFiles compatible?

Yes, I designed many systems to be an easy transition for the doctor to integrate Edge into their practice utilizing the same technique and motor settings. If a dentist switched to Edge they can still use the gutta percha points, paper points and obturators they have in stock.

Do customers need new motors for the application of the files?

The motor currently being used by dentists should be able to work with our files. The only time we advise purchasing a new motor is when a dentist wants to use one of our reciprocating systems, such as EdgeOne Fire, which works in a reversereciprocating motion and can’t be used with a rotary motor.

The heat treatment process of the EdgeEndo files seems to play a big role in the quality and thus differs from files of other manufacturers. Can you describe the advantages to us?

We spent a lot of time creating geometrically the best instruments out there. The proprietary FireWire heat-treatment process vastly improves the NiTi metallurgy, delivering excellent strength and flexibility, improving resistance to cyclic fatigue or in other words, reducing the chances our files will separate. Another benefit of FireWire NiTi is it enables EdgeEndo files to not “bounce back”, preserving canal anatomy, and carefully follows the canal as they shape.

How do you minimize the risk of file breakage with your files and are there any improved properties here compared to the files of other manufacturers?

Our files combine the attributes of being highly efficient and flexible, due to the proprietary FireWire heat treatment process, while being extremely safe and resistant to fracture. They are designed with a safe-unwinding feature. The files start unwinding before breaking. Unwinding signals to a practitioner that the file is fatigued and can break if they keep instrumenting with the file. This helps with stress and results in a more enjoyable procedure for the practitioner and patient. The patient is only in the chair for the time intended and this saves time and cost for both.

Thank you, Dr. Goodis, for these interesting insights.

DR. CHARLES J. GOODIS Founder and CEO of EdgeEndo

DEVELOPMENT OF THE MORITA TORQTECH 1:5 RED BAND HANDPIECE (PART 1)

Morita released the Torqtech Red Band Handpiece Ultra Mini in October 2022 in response to requests from many dentists. This product was finally developed despite many difficulties through the high technological skills and persistent creative efforts by engineers at J. MORITA MFG. CORP, 12 years after the first release of the Torqtech series.

We interviewed Mr. Hitoshi Tanaka, one of the engineers at J. MORITA MFG. CORP., for his insight into the development of the Torqtech Red Band Handpiece in Part 1 and the Torqtech Red Band Handpiece Ultra Mini in Part 2.

The Evolution of the Torqtech Red Band Handpiece

First, what was the background of developing the Torqtech Red Band Handpiece?

Tanaka : Dental handpieces are categorized into air turbines and motor handpieces. Air turbines are capable of fast rotation with high cutting efficiency, while motor handpieces enable precise cutting adjustment and polishing. Morita has held a large share in the air turbine market, releasing TwinPower Turbine in 2000, followed by the TwinPower Turbine X series with an anti-drawback mechanism in 2007, and the TwinPower Turbine Ultra series (Powerful Micro Head) achieving a compact turbine head in 2010.On the other hand, there were increasing needs from dentists for red band handpieces, among other motor handpieces, for fast rotation that combined efficiency and precise control. In those days, the development of Red band handpieces had been delayed in Morita. To develop a motor handpiece with competitiveness in the global market, we started the development of the red band handpiece to become a flagship product in our handpiece product range.

In the 2000s, in contrast to the smooth and ergonomic body shape of air turbines, red band handpieces were made with a square and rugged design without considerations for ergonomics or easy access. It was a common understanding in the industry that this design aspect could not be avoided due to the gear system constraints.

However, as a latecomer in the red band market, Morita needed to develop a feature that could make our product stand out and be truly competitive. This is why we decided to rigorously pursue the development of a red band handpiece with a body shape closer to that of air turbines. Inside its body, the red band handpiece increases the input rotation five times from 40,000 rpm to 200,000 rpm. This rotation is nearly 100 times faster than that of an automobile engine, which rotates at several thousands of rpm, indicating how durable the gear system incorporated in the product needs to be.

HITOSHI TANAKA Associate Engineer, Research and Development Group 1

A red band handpiece in the 2000s had a square and rugged shape, which was common in the industry.

Could you describe in more detail why the red band handpiece in those days had such a rugged shape?

Tanaka : In those days, a red band handpiece was built with two gears. The five times speed increase was achieved by about 3.7 in the body angle part, and about 1.3 inside the head. In designs based on this conventional concept, it could not be avoided to design a product with a protruding lower angle part, which interfered with front teeth during access to the molar. This was a substantial disadvantage of the red band handpiece, which could not have an ideal body shape due to more complex internal mechanisms compared to turbines.

That was the reason all other competitors' models had similarly rugged shapes?

Tanaka : Yes. As I mentioned earlier, Morita was rather late to the market of red band handpieces. Therefore, our product needed to have a distinctive feature to be accepted in the market. This is why we started development focusing on a turbine-like smooth body shape and durable gear system.

How did

the actual development proceed?

Tanaka : Usually, the design of a gear system starts with the gear part, and the body was shaped to suit the gear structure. However, this procedure only led to shapes similar to those of conventional products. Therefore, we decided to determine an ideal body shape first, and subsequently figure out how to contain the gear system inside it. With this reverse concept in mind, it was a considerable process of trial and error.The double internal bevel gear system was developed through this process. We succeeded in laying out a gear system inside the body designed as above by increasing from two to three gear sets and slightly inclining the central axes.

Development was achieved through reverse thinking to determine an ideal body shape first and subsequently exploring how to contain the gear system inside it as illustrated (the dotted lines indicate the conventional shape of red band handpiece).

This substantially improved ergonomics and access to the molars, making great advancements in practitioner and patient comfort. We are confident that this is the most ideal shape achievable at present, because further reduction in the gear size would compromise durability due to technological obstacles.

Could you describe the double internal bevel gear system in more detail?

Tanaka : To contain the gear system inside the predetermined body shape, it was essential to increase from the conventional two to three gear sets, as I mentioned earlier. By dividing gears into two stages, we could lay out the gears in steps, thereby achieving reduction in the protruding lower part, which had been the conventional problem. However, it was impossible to contain the gear system in the body shape if the first axis and second axis were laid out in parallel, because of difficulty in reducing the size of the upper angle part. We examined many gear layouts, and finally developed a double internal bevel gear system, which had an inclined second axis and used an internal gear mechanism advantageous for speed increase for the first and second gear stages.

It became possible to contain the gear system inside the predetermined body shape by increasing from two to three gear sets and laying them out with respectively inclined axes.

What is the internal gear mechanism?

Tanaka : The external gear mechanism is a common gear structure, where gears mesh externally with each other. In contrast, internal gear mechanisms have a structure where a gear meshes against another gear that has teeth inside it. This structure achieves larger teeth in a smaller space, with increased gear strength and durability. On the other hand, it causes difficulties in processing. In particular, precise processing is considered extremely difficult for internal gears with inclined axes. The outer circumference of usual gears can be processed using a cutter. On the other hand, this usual processing is difficult for a gear with internal teeth, which needs be cut out using a pencil-like tool called a “ball end mill.” It had been unthinkable in common understanding to use this method for two gear sets, because it took so much time and labor.

The double internal bevel gear system was a challenge to this preconception.

benefits both dentists and patients.

Torqtech red band handpiece achieved a turbine-like smooth body shape, thereby providing efficient access to the treatment area while reducing contact with the opposing teeth.

However, because the double internal bevel gear system was extremely specialized, there had been no means for measuring whether the processed shape conformed to the design. Therefore, we needed to develop a dedicated shape measuring device in collaboration with a device manufacturer. In those days, there were opinions in the company that doubted the commercialization of a high-quality red band handpiece. An unprecedented investment also became necessary to develop a measuring device in addition to the design of the Torqtech unit. (The double internal bevel gear system has been evaluated for its innovativeness and awarded Patent No. 5645447.)

Does the Torqtech Red Band Handpiece have any other features you want to emphasize?

Tanaka : Just like turbines, Torqtechs need lubrication, but are not continuously immersed in oil, unlike automobile gears. Therefore, we needed to design the gears to withstand friction with only a thin layer of oil. This really highlights the importance of the precision and durability of gear teeth. Torqtech red band handpiece use an involute tooth profile based on involute curves for all its gears. An involute curve is a curve formed when a string is wrapped around a circle and then unwrapped. A gear processed in this shape minimizes slipping, rotates smoothly and efficiently, and reduces friction. Nevertheless, the gear would rapidly wear out if made of a common material. We use a special material that is extremely hard and withstands friction.

Torqtech red band handpiece use an involute tooth profile based on involute curves, thereby achieving smooth rotation that minimizes stress.

The Torqtech red band handpiece uses double internal gear sets. By using internal gears with inclined axes, despite the extreme difficulties in processing, the product achieves increased gear strength, durability, and access, thereby prioritizing precise treatment that

A HANDPIECE THAT’S A MASTER OF ITS DOMAIN

One clinician shares why she’s relied on the mastertorque lux for years, and why she won’t use any other handpiece.

With her KaVo MASTERtorque LUX M9000L highspeed airdriven handpiece always at the ready, Dr. Siti Lowery says she has one less thing to worry about during her workday. She’s relied on the handpiece in her Cary, NC, practice for years, and said it’s the only one she’s purchased since opening her office and buying her own equipment.

The high-performing handpiece offers a host of benefits, including 31 watts of power, 57 dB for quiet operation and a more pleasant treatment experience, and Direct Stop Technology (DST) for increased patient safety and reduced risk of crosscontamination. One of the most notable benefits the handpiece offers, though, is reliability.

“KaVo has been my gold standard. I knew when I invested in a handpiece, it was going to be from KaVo,”

Dr. Lowery said, noting the M9000L was the “hot” handpiece being recommended at the time.

“And this handpiece has been reliable; I know I can depend on it no matter what.”

The Perfect Fit

Dr. Lowery enjoys the Goldilocks effect of the handpiece, which she says fits perfectly into her hand—unlike other brands she’s tried. It also provides smooth operation; she doesn’t feel it

vibrate as she works in a patient’s mouth, which improves comfort during the procedure.

“I have small, petite hands, and it’s just the right weight and shape to fit into them comfortably,” she said.

“It’s not too skinny and it’s not too fat. It’s just right!”

Predictable Performance

Dr. Lowery uses the MASTERtorque LUX M9000L handpiece primarily to prep for crowns and composite restorations, but regardless of the procedure at hand, it works well. In fact, she describes its performance as better than any other handpiece she’s ever used.

“It’s predictable, and as dentists, we like predictable,” she said.

“If your hand is steady, you’re going to get smooth cuts.”

High-Quality Construction

The team at KaVo manufactures every part that goes into their handpieces, which means that each instrument employs the high quality that comes with German engineering. Dr. Lowery appreciates the durability that this superior construction gives the M9000L.

“It holds up,” she said. “And it still looks good, even after years of use.”

“It’s predictable, and as dentists, we like predictable. If your hand is steady, you’re going to get smooth cuts.”

A Better Experience

There’s no question the powerful MASTERtorque LUX M9000L is Dr. Lowry’s go-to handpiece; she doesn’t have any interest in using anything else. And if she does happen to pick up what she describes as one of the practice’s “imposter” handpieces, she can tell the difference right away. It doesn’t feel the same and it certainly doesn’t perform as well. The handpiece’s high-quality construction and the enhanced experience it provides are simply unmatched.

“It’s my preferred handpiece, by far,” she said. “It’s my workhorse. That’s what I call it.”

Any dentist looking for a durable, high-performing handpiece can’t go wrong investing in the MASTERtorque LUX M9000L.

“It’s seamless and predictable,” Dr. Lowery said. “It takes the question out of your days.”

The DST advantage – KaVo’s Direct Stop Technology stops the bur in less than 1 second on average when the foot control is released. This not only increases efficiencies, but it also reduces the likelihood of soft tissue damage. This feature also prevents aerosols and debris drawback, lengthening turbine life. The MASTERtorque LUX M9000L also features:

• 31 Watts of Peak Power

• 20% more torque than previous generations

• Industry leading noise level of 57 db

PRE-CLEANING: THE FOUNDATION FOR EFFECTIVE INSTRUMENT REPROCESSING

Precleaning is the beginning of the journey of reprocessing, and arguably the part that attracts the least attention, despite its importance. Appropriate precleaning steps that are undertaken at the chair side can dramatically reduce the amount of adherent material (including blood, salivary proteins, cements and bonding agents) on instrument surfaces. The 2024 Australian Dental Association Infection Prevention and Control Guidelines highlight the importance of precleaning steps, from those that occur during treatment and at the chair side, through to those that are undertaken prior to mechanical cleaning, once items have left the area where patient treatment is being undertaken.

Precleaning using a multi-enzyme approach has been a part of the protocol for reprocessing rotary nickel-titanium endodontic files for over 20 years. As a result, many dental practices have become more familiar with the use of multienzyme products for the pre-treatment of instruments before the cleaning process is commenced.

Cleaning solutions with multiple enzymes are specifically designed to handle a variety of organic and inorganic substances that stick to dental instruments. These solutions usually contain a mix of enzymes, such as proteases, lipases, amylases, and other types of carbohydrases. Proteases will break down proteins present in blood and saliva, while lipases focus on fats and lipids, and carbohydrases break down carbohydrates and organic substrates such as those in dental cements and bonding agents. This multi-enzyme strategy guarantees a thorough disintegration of bioburden, thereby enhancing the efficiency and effectiveness of the cleaning procedures that follow.

There are several advantages of employing a multienzyme treatment for dental instruments. They enhance the efficacy of the cleaning process by decomposing organic substances at a molecular level.

This aids in preventing the creation of biofilms during the time the instruments are soaking. Biofilms are difficult to eliminate and can harbor harmful pathogens. An effective cleaning solution can also extend the lifespan of instruments by preventing corrosion using corrosion inhibitors.

Several factors play a crucial role in determining the activity and effectiveness of multi-enzyme solutions. Firstly, temperature is a significant factor, since enzymes are sensitive to temperature changes. Most multi-enzyme solutions are designed to function at room temperature, which is typically 20-25°C. However, increasing the temperature to 40°C can considerably enhance enzyme activity, and accelerate the breakdown of contaminants. It is important to stay within the recommended temperature range, as excessively high temperatures will denature the enzymes, making them ineffective. Secondly, the duration of exposure to the multi-enzyme solution is critical. A soaking time of 10-20 minutes can be sufficient for the enzymes to act on the bioburden. Extended soaking can enhance cleaning efficiency, but it is essential to adhere to the manufacturer's guidelines to prevent potential damage to the instruments. Thirdly, some multi-enzyme products are designed to be used during ultrasonic cleaning. The agitation effects gained from cavitation significantly boost the effectiveness of the agent, since ultrasound waves create jet streams on the rigid surface of items when the microscopic bubbles created by cavitation collapse. This aids in dislodging debris, giving more effective cleaning, and reducing the time needed.

Fourthly, mild agitation, either manually or through mechanical means, can increase the extent of contact between the enzymes in solution and contaminants on instrument surfaces, thereby improving the breakdown process. Agitation helps distribute the enzymes evenly through the solution and across the instrument surfaces, ensuring comprehensive cleaning.

The concentration of the enzyme solution is another critical factor. Manufacturers provide specific dilution instructions to achieve the optimal concentration for effective cleaning. Using the solution at the correct concentration ensures that there is sufficient enzyme activity to break down bioburden efficiently. In addition to these factors, the pH of the solution, the hardness of the water used, and the presence of inhibitors or activators can also influence the effectiveness of multi-enzyme solutions. The influence of these variables was seen in a comprehensive analysis that we undertook of commercially available cleaning solutions for dental instruments, when we evaluated the various parameters that influenced their efficiency.

Effective cleaning of STF Browne Load Check® Indicators by ultrasonic cleaning over a period of 30-min with various commercial detergents at their manufacturer-designated concentrations at a temperature of 40°C.

and non-enzyme-based detergents

Therefore, it is important to optimise all these factors when using multi-enzyme cleaning solutions for cleaning dental instruments.

Based on the foregoing results it can be concluded that multi-enzyme cleaners are highly effective in removing biofilms, blood residues, and microbial contaminants from dental instruments. Multi-enzyme cleaners that include disinfectants also reduce the overgrowth of bacteria that otherwise occurs during a prolonged holding period when items are submerged, and thereby enhances environmental hygiene in the reprocessing area. Their actions are superior to simply leaving instruments immersed in tap water, or in tap water to which ordinary detergents or chlorine compounds have been added.

OPTIZYME ULTRA D

AN ADVANCED TOOL FOR DENTISTRY

Novapharm has been a research leader in the use of enzyme detergent medical instrument reprocessing for 3 decades. The last 15 years has seen an almost total replacement of the old style alkaline detergents by near neutral enzyme detergent formulations which have proven to be safer, more efficacious, more cost effective and more instrument compatible.

Recently it became clear that the challenges in reprocessing dental instruments are somewhat different from medical requirements and therefore a research project focussed on developing an enzymatic cleaner specifically to meet this dental challenge was undertaken five years ago.

The result is Optizyme Ultra D - an aqueous, multi-enzyme detergent concentrate developed specifically for dental instrument reprocessing. This formulation has proven to offer superior cleaning efficacy and is applicable to all dental instruments and cleaning modalities i.e. sinks, ultrasound baths and automated washers.

The unique features of the product focussed on satisfying the currently unmet dental requirements are:

• Clear, low foaming solution, fully compatible with manual washing, ultrasound baths and automated washers

• The ability to clean both organic and inorganic soils (bone, pulp, amalgam, ionomer as well as all human secretions).

• Digests and removes biofilm

• Contains rust and corrosion inhibitor

• The inclusion of a disinfecting system which ensures that the cleaning sink or ultrasound bath does not become a source of crossinfection after being in continuous use with a multiplicity of soiled instruments for many hours. (N.B. the product is not an instrument disinfectant)

Optizyme Ultra D is easily used in exactly the same way as other currently available instrument cleaners. It is simply added to the bath water or automated washer at the rate stated on the label.

WHY NZ DENTAL PRACTICES SHOULD ADOPT PIEZOTOME TECHNOLOGY

CHRISTOPHER MOORE (NATIONAL SALES MANAGER ACTEON UK)

In the rapidly advancing field of dental surgery, ensuring patient safety, comfort, and optimal clinical outcomes is a priority for any modern dental practice. One technology that is making a significant impact in achieving these goals is piezotome technology, such as the ACTEON CUBE For NZ dental practices, adopting this innovation could elevate the standard of care across a range of procedures, including bone surgeries, extractions, sinus lifts, crest splitting, and crown extensions.

Precision and Safety: A New Era in Bone Surgery

Piezotome technology uses ultrasonic vibrations to precisely cut bone while preserving adjacent soft tissues, afeature that traditional rotary instruments simply cannot match. This precision is especially valuable in complex procedures like sinus lifts and crest splitting, where accuracy is critical to avoid complications. By minimising trauma to surrounding tissues, piezotomes not only enhance surgical precision but also reduce the risk of unintended damage to nerves, blood vessels, and membranes.

Improved Patient Experience

Patient comfort is at the forefront of any dental procedure. Unlike traditional bone cutting tools, piezotomes operate at ultrasonic frequencies that reduce trauma to the bone. This translates into less post-operative swelling, reduced bleeding, and shorter recovery times, offering a far more comfortable experience for patients undergoing extractions or crown extensions. In a highly competitive market, the ability to offer minimally invasive surgery can help attract and retain patients who prioritise a smoother and faster recovery.

Faster Healing and Long-Term Outcomes

One of the key advantages of piezotome technology is its ability to promote faster and more predictable healing. Because the technique is less invasive and causes minimal damage to the surrounding tissues, it helps preserve blood supply and bone integrity.

This is particularly beneficial in sinus lifts and bone grafting, where maintaining the health of the bone is crucial for successful outcomes. In the long run, this can lead to more predictable and stable results, enhancing patient satisfaction and practice reputation.

Versatility Across Procedures

From routine tooth extractions to advanced bone surgeries, the Acteon CUBE and other piezotome devices offer versatility that is unmatched by conventional tools. Whether it’s refining bone cuts during crest splitting or performing delicate work in crown extensions, piezotomes provide dental professionals with greater control and precision. This adaptability makes them invaluable across a wide range of surgical applications, enabling practices to expand their service offerings and improve clinical outcomes.

Enhancing

Your Practice’s Reputation

Set your practice apart & enhance your practice’s reputation within the community.

Being able to advertise the use of minimally invasive techniques that reduce recovery times and enhance comfort is a compelling proposition for patients.

Conclusion: A Strategic Investment

Adopting piezotome technology such as the Acteon CUBE isn’t just about staying ahead of the curve; it’s about delivering better care. The precision, patient comfort, and faster healing associated with this technology make it an essential tool for dental practices that aim to provide the highest standard of treatment. For NZ dental practices looking to elevate their offerings, piezotome technology represents a strategic investment that pays off in patient satisfaction and clinical success.

MOLAR HYPOMINERALISATION

CHALKY TEETH - A SILENT EPIDEMIC DAMAGING 1 IN 5 CHILDREN’S TEETH*

What is Molar Hypomineralisation?

Molar Hypomin is a common developmental condition affecting primarily one or more first permanent molars.1-3 Central incisors may be affected as well, but this usually occurs to a lesser extent.1-3 Hypomineralisation of the second deciduous molars (HSPM) or canines may also occur.1-3 Molar Hypomin enamel presents low levels of calcium and phosphate. Molar Hypomin is characterized by whiteyellow enamel patches and dentine hypersensitivity. Variations in severity exist, ranging from mild opacities to post eruptive enamel breakdown. While Molar Hypomin affects patients’ quality of life, it also creates treatment challenges, which can lead to ongoing restorations and more complex care.1-4

What causes Molar Hypomin?

Recently published new research findings showed that serum albumin plays a direct role in the pathogenesis of molar hypomin.4 For more info visit: www.ncbi.nlm.nih.gov/pmc/articles/PMC7303361/

What are the Molar Hypomin clinical challenges?

• Molar Hypomin teeth are formed with less mineral, which makes them more prone to break down during chewing and tooth brushing.

• Once erupted, Molar Hypomin teeth may start to break down, even without excess sugars or acids in the diet.

• Tooth sensitivity and pain are common, which might lead to poor oral hygiene and therefore, increased caries risk.

• Difficulty in achieving anaesthesia, which are possibly related to chronic pulp inflammation

• Limited cooperation of young patients, due to dental fear and anxiety.

• Repeated marginal breakdown of restorations, leading to dentine exposure and risk of pulp involvement.

Tooth Surface Protection

It is particularly important that Molar Hypomin teeth are looked after carefully to limit problems. Management of Molar Hypomin teeth should include long-term prognosis, as well as management of the presenting concerns, such as pain.

IMPORTANCE OF INTERDENTAL CLEANING

A RECOMMENDATION GUIDE FOR DENTAL PRACTITIONERS

Efficient cleansing and removal of plaque biofilm from tooth and restoration surfaces is key to ensuring our patients have good dental health. In addition to brushing twice daily, we must also encourage patients to clean interdentally equally as frequently given plaque tends to accumulate between the teeth more, compared to other tooth surfaces. Hence, dental diseases like caries and periodontal disease occur more interdentally.1 Given there are plenty of different interdental cleaning tools available for patients to use, which tools are best for their situation, is one of the frequently asked questions of dental professionals. In this article, each of the interdental cleaning tools will be explored to better guide clinicians on recommending the ideal tool for their patients to support their oral health.

Why Interdental Cleaning

As dental professionals, it is our responsibility to help educate our patients on how to best maintain healthy teeth, implants and restorations for a lifetime. Studies have shown that tooth brushing alone only removes around 60% of plaque from the oral cavity.2 Therefore interdental cleaning is an important adjunctive step to ensure the remaining 40% of plaque that is missed can be effectively cleaned to reduce the risk of dental diseases and promote good dental health.

Dental Floss

There are different types of dental floss available for patients and dental clinicians to use - regular string floss, dental tape and floss holders/flossettes. Although dental floss as an interdental cleaning tool was conceptualised almost two centuries ago, the evidence on its effectiveness remains ambiguous. A recent Cochrane systematic review suggested flossing combined with toothbrushing may reduce gingivitis compared to toothbrushing alone however the overall certainty of evidence was low.4 This is likely due to the technique-sensitive nature of flossing leading to ineffective interdental cleaning and thus lack of patient compliance. Floss thread or tape can either be waxed or unwaxed; the former providing a smoother surface to glide between teeth surfaces. One major advantage of floss is

that it is relatively cheap and travel friendly. Especially in the case of very tight interdental spaces or crowding of teeth, floss is usually the best tool to access these narrow areas. Should patients struggle with the manual dexterity needed for flossing, the use of floss holders or flossettes can improve compliance and adherence to a long term habit. Like floss, they are quite affordable and travel friendly. From a utility point of view, most flossettes also have the handle designed as a toothpick to remove food debris interdentally.

Wood Sticks/Toothpicks

Wooden toothpicks are one of the earliest devices used by humans historically to remove food debris. Wood Sticks tend to be triangular in shape whereas toothpicks are round in shape. Whilst these are relatively cheap, easy to use and tend to be used particularly by the elderly who have a habit of removing food with them, they can cause gingival trauma and splinters. In some cases toothpicks can also cause attritional tooth surface loss interdentally with long term aggressive force; usually characterised in intraoral radiography by circular radiolucencies under the contact point.4 To counteract the disadvantages of wood, there are now soft, flexible, plastic toothpicks available which have a perforated design with a thin, triangular cross-section to better cleanse interdentally compared to round wooden toothpicks. These are a much better solution for patients who prefer to use toothpicks without traumatising the gingiva.

Interdental Brushes

Interdental brushes initially were designed to be used by patients who had lost their interdental papillae as a result of periodontal disease, leading to wider embrasures and food and plaque still being trapped after flossing. Whilst patients with intact and healthy dental papillae were encouraged to use floss, interdental brushes now come in a variety of standardised sizes to fit a range of embrasure spaces to facilitate better interdental cleaning.

Compared to toothpicks, the bristled, wire brushes or soft, flexible, rubber nibs tend to pick up more plaque; thus leading to more effective plaque removal.5 Since they do not need to pass through an interdental contact point and are therefore easier to use than floss, compliance is better amongst patients. However, patients must still be warned against aggressive use as they can cause gingival trauma. Most importantly, interdental brushes need to be correctly sized with a sizing probe by dental practitioners for each interdental space in the mouth. Therefore, an individual patient may need to use a multitude of different-sized interdental brushes to effectively clean between their teeth. Aside from periodontal patients, interdental brushes are also useful for patients undergoing orthodontic treatment with traditional fixed brackets and wires. Floss is blocked by the orthodontic wire, but interdental brushes can easily slip under the wire to effectively clean the interdental spaces.

Oral Irrigators

Oral irrigators are electric, interdental cleaning tools that either use water or air to clean around and between the teeth. Water flossers use a jet stream of water to clean whereas air flossers use jets of air combined with water droplets to remove food debris interdentally 6 Their mechanical mode of action relies on a combination of pulsation and pressure to remove supragingival plaque, subgingival plaque and other debris whilst stimulating the gingival tissues. There are two zones of hydrokinetic energy produced by the pulsating action - the impact zone and the flushing zone. The impact zone is where the solution initially contacts the gingival margin whereas the flushing zone is where the water reaches subgingivally 3 A pulsating water jet regulates the water pressure in the device and relies on the fact that attached gingiva can sustain pressure of up to 160 psi (pounds per square inch) for 30 seconds resulting in no permanent damage. Some studies estimate that for undamaged or healthy gingival tissues, a pressure of 90 psi is acceptable whereas for inflamed or ulcerated gingival tissues, a pressure of 50-70 psi is recommended.7 Like interdental brushes, oral irrigators are indicated for patients who have wider embrasure spaces resulting from the loss of interdental papillae. However, they are also indicated to maintain good periodontal health around dental implants, bridges and patients wearing orthodontic appliances such as fixed braces. The main advantage of oral irrigators is the ease of use for patients with limited manual dexterity such as patients with disabilities, arthritis or the elderly. Patients can also mix adjunctive therapeutic mouth rinses in the water tank reservoirs of oral irrigators to better manage periodontal disease. However, these appliances can be costly and given they require water, a sink and power to charge their batteries, they are therefore less travel friendly compared to interdental brushes and floss.

Since patients have a number of interdental cleaning tools available to them to use, dental practitioners should continue to recommend personalised interdental cleaning tools for their patients based on their individual needs. More importantly, this should also extend to determining the ideal tools based on their manual dexterity or capability to achieve a safe and high standard of interdental cleaning. When the appropriate tool is matched to the patient’s specific needs and ability to easily maintain this habit in the long term, this allows us as dental practitioners to optimise a patient’s dental hygiene and health.
