Back From The Greater NY Dental Meeting

I went in for my annual pilgrimage to the the Javits Center for the Greater NY Dental Meeting. It is a very large meeting. Well the first thing to report about is there is nothing new to report. That's right! This is not a big meeting for new stuff but usually there is something. I was told of a few products getting ready for future release. So I expect to be writing about some very exciting things come the end of February and the Chicago Mid Winter meeting. Otherwise it was the usual end of year wheeling and dealing as manufacturers try to close out the 4th quarter on the up swing.

So my dental meetings for 2008 come to a close. One more lecture to do next month and that will be all until 2009. Not to worry blog posts don't take lots of time off even during the holidays.

Bad Breath Linked To Bacteria That Cause Stomach Ulcer And Cancer

Nao Suzuki, Masahiro Yoneda, Toru Naito, Tomoyuki Iwamoto, Yousuke Masuo, Kazuhiko Yamada, Kazuhiro Hisama, Ichizo Okada and Takao Hirofuji
J Med Microbiol 57 (2008), 1553-1559; DOI: 10.1099/jmm.0.2008/003715-0

Helicobacter pylori infection, which causes peptic ulcers and gastric cancer, is considered a possible cause of halitosis. Recently, the oral cavity was identified as a possible H. pylori reservoir, particularly in the presence of periodontal disease, which is a cause of halitosis. The purpose of this study was to evaluate by PCR the prevalence of oral H. pylori in the saliva of subjects complaining of halitosis. Samples were obtained from 326 non-dyspeptic subjects, comprising 251 subjects with actual malodour and 75 subjects without halitosis. DNA was extracted from the samples, and the presence of H. pylori and periodontopathic bacteria including Porphyromonas gingivalis, Treponema denticola and Prevotella intermedia was examined by PCR. H. pylori was detected in 21 (6.4 %) of 326 samples. The methyl mercaptan concentration and periodontal parameters including tooth mobility, periodontal pocket depth (PPD) and occult blood in the saliva were significantly greater in the H. pylori-positive subjects. Each of the periodontopathic bacteria was also detected at a significantly higher frequency in the H. pylori-positive subjects. Among those patients with a PPD of ≥5 mm and a tongue coating score of ≤2, no difference was observed in oral malodour levels between the H. pylori-positive and -negative subjects. However, the presence of occult blood in the saliva and the prevalence of Prevotella intermedia were significantly greater in the H. pylori-positive subjects. H. pylori was detected in 16 (15.7 %) of 102 subjects with periodontitis, suggesting that progression of periodontal pocket and inflammation may favour colonization by this species and that H. pylori infection may be indirectly associated with oral pathological halitosis following periodontitis.

Japan scientists eye made-to-order bones


Read the entire article at Yahoo News

TOKYO (AFP) – Japanese hospitals are running a clinical trial on the world's first custom-made bones which would fit neatly into patients' skulls and eventually give way to real bones.

If successful, the Japanese method could open the way for doctors to create new bones within hours of an accident so long as the patient has electronic data on file.

Doctors usually mend defective bones by transplanting real bones or ceramic substitutes. The Japanese implants use a powder of calcium phosphate, the substance that makes up real bones.

The new implants are called CT Bone as they are crafted using the patient's computer tomography (CT) data, a form of medical imaging.

It can match the complicated structures of the jaw, cheek and other parts of the skull down to one millimetre (0.039 of an inch), a level significant enough to make a difference in human faces, researchers told AFP.

"It can also be replaced by your own bone, which wasn't possible before" with conventional sintered ceramic bones, said Tsuyoshi Takato, an orthopedic surgeon and professor at the University of Tokyo's Graduate School of Medicine.

The implants are currently limited to use in the skull because, unlike limbs, they do not have to carry the body weight.

Root Canal or Dental Implant?

Dental Professionals and Patients Should Strive to Preserve Natural Teeth Before Considering Implants

CHICAGO, IL, November 13, 2008 – A new study addresses the growing controversy among dental health professionals regarding the best course of treatment when evaluating between a root canal or dental implant procedure. Researchers evaluated the success and failure rates of teeth treated with a root canal (endodontically treated teeth) or extracted and replaced with a dental implant. While the findings concluded that the success rate of each treatment was similar, the data showed that significantly more dental implants required additional treatment or surgical intervention after the procedure compared to endodontically treated teeth (12.4 percent vs. 1.3 percent, respectively).

“Many dental professionals today are faced with the dilemma of whether root canal treatment or dental implants are the best option for their patients,” said lead investigator James Porter Hannahan, D.M.D., of the University of Alabama at Birmingham, Birmingham, Ala. “While the success of both procedures is similar, saving the natural tooth through a root canal rarely requires follow-up treatment and generally lasts a lifetime; implants, on the other hand, have more postoperative complications and higher long-term failure rates.”

Research has shown that poor oral health and tooth loss may lead to serious medical conditions, such as heart disease, stroke, diabetes and even certain types of cancer. Given this connection, taking the right steps to prevent tooth loss can be important for maintaining better overall health.

“Considering these results in light of the growing body of evidence on the impact of oral health on overall health, it is imperative for dental professionals to partner with endodontists who have advanced training in examining whether a natural tooth can be saved through root canal treatment,” said Dr. Louis Rossman, an endodontist and president of the American Association of Endodontists, the dentists who specialize in root canals. “While implants may be an appropriate solution for people with missing teeth, endodontic treatment should be the first choice for restoring a compromised tooth.”

Because of the increasing popularity of dental implants, patients may not realize the long-term implications of the procedure or that root canals may be healthier and less complicated in the long-run. Dental professionals should ensure they explain to patients the differences between each procedure.

Dental implants require extracting the tooth followed by multiple surgeries to insert a metal post in the jaw and affix a porcelain crown to the post. These surgeries often can take three or more visits over the course of several months to complete and can be time-intensive and costly. During root canal treatment, the source of tooth pain – an inflamed pulp – is removed and the inside of the tooth is then cleaned, filled and sealed. Today, most root canals can be completed in one visit and are virtually painless. In fact, root canals restore and save an average of 17 million teeth each year.

When considering treatment options, the AAE emphasizes that decisions must be based on factors other than outcome, such as case complexity or the patient’s individual health and preferences. To assist dental professionals and their patients in determining the most appropriate treatment, the AAE has formal guidance on treatment planning, which includes evaluating various risk factors and other implications associated with root canal and implant treatment. Risk factors can include smoking, bone quality and estrogen levels – for example, women with lower estrogen levels may encounter more treatment failures with implants.

Additional Study Information
Based on inclusion criteria, study investigators evaluated patient charts of 129 dental implants for an average of 36 months (range, 15-57 months) and of 143 endodontically treated teeth for an average 22 months (range, 18-59 months). Implant data were collected from a periodontic group practice and root canal data were collected from an endodontic group practice. Researchers placed each procedure into one of three categories: success, uncertain and failure. Success was defined as radiographic evidence that the implant or treated tooth was still present in the mouth and there were no signs or symptoms requiring intervention during the follow-up treatment period. Failures were defined as the removal of the implant or tooth.

Investigators found two failures of the 129 dental implants for a success rate of 98.4 percent. They also found only one failure of the 143 endodontic treatments for a success rate of 99.3 percent. These results were not statistically significant (P=.56) with the Fisher exact test, a statistical significance test. However, 12.4 percent of the dental implants required additional surgical procedures, whereas only 1.4 percent of the endodontically treated teeth required additional surgery, which was statistically significant (P=.0003).

This study is published in the November issue of the Journal of Endodontics, the official journal of the AAE. These data were collected as part of a larger project comparing implant and endodontic outcomes and is funded by the AAE Foundation.

Dentists' knowledge and implementation of the 2007 American Heart Association guidelines

Oral Surg Oral Med Oral Pathol Oral Radiol Endod. 2008 Dec;106(6):e16-9.

Dentists' knowledge and implementation of the 2007 American Heart Association guidelines for prevention of infective endocarditis.

Zadik Y, Findler M, Livne S, Levin L, Elad S; American Heart Association.

Department of Oral Medicine, Hebrew University-Hadassah School of Dental Medicine, Jerusalem, Israel. yzadik@gmail.com

OBJECTIVES: Our aim was to evaluate the knowledge and implementations of the 2007 American Heart Association guidelines for the prevention of infective endocarditis (IE) among practicing Israeli dentists, 12 months after their publication. STUDY DESIGN: A total of 118 dentists completed a questionnaire regarding required antibiotic prophylaxis for 10 specific cardiac patient subtypes before invasive dental treatment, prophylactic need in at-risk patients for IE in 10 dental procedures, and prophylactic regimen for nonallergic patients. RESULTS: Correct answer response for cardiac conditions was 81.3% (highest failure: mitral valve prolapse [MVP] with regurgitation). There was a consensus among the participants regarding antibiotic regimen for high-risk patients during several dental procedures, such as intraoral radiography, tooth extraction, and periodontal surgery, but a controversy for other procedures. The procedures of disagreement were endodontic treatment, tooth preparation with oral impressions, and restoration of class II caries lesion. Correct antimicrobial agent, dose, and timing were prescribed by 99%, 93.8%, and 100% of the respondents, respectively. CONCLUSIONS: Relatively high level of knowledge of the new guidelines was found among dentists, reflecting both familiarity of the practitioners with the guidelines and acceptance of guidelines. Prophylactic need is ambiguous during restorative, endodontic and prosthetic procedures. Educational resources should emphasize these guidelines, specifically the reduced risk level for MVP with regurgitation patients.

Bleach kills bacteria, but how?

Clean results: U-M researchers learn how bleach kills bacteria

ANN ARBOR, Mich.—Developed more than 200 years ago and found in households around the world, chlorine bleach is among the most widely used disinfectants, yet scientists never have understood exactly how the familiar product kills bacteria.

New research from the University of Michigan, however, reveals key details in the process by which bleach works its antimicrobial magic.

In a study published in the Nov. 14 issue of the journal Cell, a team led by molecular biologist Ursula Jakob describes a mechanism by which hypochlorite, the active ingredient of household bleach, attacks essential bacterial proteins, ultimately killing the bugs.

"As so often happens in science, we did not set out to address this question," said Jakob, an associate professor of molecular, cellular and developmental biology. "But when we stumbled on the answer midway through a different project, we were all very excited."

Jakob and her team were studying a bacterial protein known as heat shock protein 33 (Hsp33), which is classified as a molecular chaperone. The main job of chaperones is to protect proteins from unfavorable interactions, a function that's particularly important when cells are under conditions of stress, such as the high temperatures that result from fever.

"At high temperatures, proteins begin to lose their three-dimensional molecular structure and start to clump together and form large, insoluble aggregates, just like when you boil an egg," said lead author Jeannette Winter, who was a postdoctoral fellow in Jakob's lab. And like eggs, which once boiled never turn liquid again, aggregated proteins usually remain insoluble, and the stressed cells eventually die.

Jakob and her research team figured out that bleach and high temperatures have very similar effects on proteins. Just like heat, the hypochlorite in bleach causes proteins to lose their structure and form large aggregates.

"Many of the proteins that hypochlorite attacks are essential for bacterial growth, so inactivating those proteins likely kills the bacteria," said second author Marianne Ilbert, a postdoctoral fellow in Jakob's lab.

These findings are not only important for understanding how bleach keeps our kitchen countertops sanitary, but they may lead to insights into how we fight off bacterial infections. Our own immune cells produce significant amounts of hypochlorite as a first line of defense to kill invading microorganisms. Unfortunately, hypochlorite damages not just bacterial cells, but ours as well. It is the uncontrolled production of hypochlorite acid that is thought to cause tissue damage at sites of chronic inflammation.

How did studying the protein Hsp33 lead to the bleach discovery? The researchers learned that hypochlorite, rather than damaging Hsp33 as it does most proteins, actually revs up the molecular chaperone. When bacteria encounter the disinfectant, Hsp33 jumps into action to protect bacterial proteins against bleach-induced aggregation.

"With Hsp33, bacteria have evolved a very clever system that directly senses the insult, responds to it and increases the bacteria's resistance to bleach," Jakob said.

2008 CDC Guidelines On Sterilization and Disinfection

The Guideline for Disinfection and Sterilization in Healthcare Facilities, 2008 has been posted at http://www.cdc.gov/ncidod/dhqp/pdf/guidelines/Disinfection_Nov_2008.pdf
The guideline will also be published in the MMWR at a later date.
-----------------------------------------------------

Dental Instruments
Scientific articles and increased publicity about the potential for transmitting infectious agents in dentistry have focused attention on dental instruments as possible agents for pathogen transmission207, 208. The American Dental Association recommends that surgical and other instruments that normally penetrate soft tissue or bone (e.g., extraction forceps, scalpel blades, bone chisels, periodontal scalers, and surgical burs) be classified as critical devices that should be sterilized after each use or discarded. Instruments not intended to penetrate oral soft tissues or bone (e.g., amalgam condensers, and air/water syringes) but that could contact oral tissues are classified as semicritical, but sterilization after each use is recommended if the instruments are heat-tolerant 43, 209. If a semicritical item is heat–sensitive, it should, at a minimum, be processed with high-level disinfection 43, 210. Handpieces can be contaminated internally with patient material and should be heat sterilized after each patient. Handpieces that cannot be heat sterilized should not be used. 211 Methods of sterilization that can be used for critical or semicritical dental instruments and materials that are heat-stable include steam under pressure (autoclave), chemical (formaldehyde) vapor, and dry heat (e.g., 320ºF for 2 hours). Dental professionals most commonly use the steam sterilizer 212. All three sterilization procedures can damage some dental instruments, including steam-sterilized hand pieces 213. Heat-tolerant alternatives are available for most clinical dental applications and are preferred43.
CDC has divided noncritical surfaces in dental offices into clinical contact and housekeeping surfaces43. Clinical contact surfaces are surfaces that might be touched frequently with gloved hands during patient care or that might become contaminated with blood or other potentially infectious material and subsequently contact instruments, hands, gloves, or devices (e.g., light handles, switches, dental X-ray equipment, chair-side computers). Barrier protective coverings (e.g., clear plastic wraps) can be used for these surfaces, particularly those that are difficult to clean (e.g., light handles, chair switches). The coverings should be changed when visibly soiled or damaged and routinely (e.g., between patients). Protected surfaces should be disinfected at the end of each day or if contamination is evident. If not barrier-protected, these surfaces should be disinfected between patients with an intermediate-disinfectant (i.e., EPA-registered hospital disinfectant with tuberculocidal claim) or low-level disinfectant (i.e., EPA-registered hospital disinfectant with an HBV and HIV label claim) 43, 214, 215.
Most housekeeping surfaces need to be cleaned only with a detergent and water or an EPA-registered hospital disinfectant, depending of the nature of the surface and the type and degree of contamination. When housekeeping surfaces are visibly contaminated by blood or body substances, however, prompt removal and surface disinfection is a sound infection control practice and required by the Occupational Safety and Health Administration (OSHA) 43, 214.
Several studies have demonstrated variability among dental practices while trying to meet these recommendations216, 217. For example, 68% of respondents believed they were sterilizing their instruments but did not use appropriate chemical sterilants or exposure times and 49% of respondents did not challenge autoclaves with biological indicators216. Other investigators using biologic indicators have found a high proportion (15%–65%) of positive spore tests after assessing the efficacy of sterilizers used in dental offices. In one study of Minnesota dental offices, operator error, rather than mechanical malfunction218, caused 87% of sterilization failures. Common factors in the improper use of sterilizers include chamber overload, low temperature setting, inadequate exposure time, failure to preheat the sterilizer, and interruption of the cycle.
Mail-return sterilization monitoring services use spore strips to test sterilizers in dental clinics, but delay caused by mailing to the test laboratory could potentially cause false-negatives results. Studies revealed, however, that the post-sterilization time and temperature after a 7-day delay had no influence on the test results219. Delays (7 days at 27ºC and 37ºC, 3-day mail delay) did not cause any predictable pattern of inaccurate spore tests 220.

Risky Business: The Choking Game

Here is some information for all dentists and parents alike. I was unaware of this type of activity. Now maybe we can help prevent a tragedy for someone. MJ



Risky Business: The Choking Game

Teens experiment with attitudes, appearances, and behaviors. While most of it is harmless, some experiments can have tragic results.

One experiment that backfires involves young people trying to get high by choking themselves or their friends. Teens—usually in middle school and early high school—try it alone or with others. They do it for the perceived high that occurs as oxygen rushes back to the brain—putting the player at high risk for nerve damage, even death.

Sound dangerous?

It is.

The challenge of losing consciousness and reviving is known by many names, including: pass-out, tingling, blackout, choking game, suffocation roulette, and other names in different areas of the country.

Dentrix G4 is coming soon!

I have heard that the beta for G4 is wrapped up so expect to see Dentrix G4 in the first and second quarter of 2009. If you have not upgraded to G2 or G3 its time to get a move on. Dentrix usually only supports the previous two versions of the software, so support for version 11 may be going away. My office is currently on G3 and we are not having any problems. So in this calendar year we did the G2 and G3 upgrades and went chartless. Yes there are minor issues such as the speed at which the chart and treatment planner load but these are not big enough problems to mitigate the huge benefits. So if you need to upgrade some of that legacy hardware and take the plunge into the upgrades. If you do upgrade to G3 make sure you get the component upgrades from the Dentrix web site.

Eye-Fi Unveils the 4GB Eye-Fi Anniversary Edition


I talk about these Sd cards in my lectures. They work well for getting pictures into the computer via Wi-Fi. MJ

Eye-Fi Celebrates First Anniversary with 4GB Limited Edition
Anniversary Card and the Win of Popular Science's Best of What's New Award

MOUNTAIN VIEW, Calif., Nov. 12 /PRNewswire/ -- Today Eye-Fi Inc.
(http://www.eye.fi) announced a new, limited edition card -- the Eye-Fi
Anniversary Edition -- to celebrate the one-year anniversary of its first
wireless SD memory card for digital cameras. Eye-Fi also announced it has
been chosen as one of Popular Science's 2008 "Best of What's New" award
recipients.

"For the past year, we've been reinventing the way people save and
share their digital memories," said Jef Holove, CEO of Eye-Fi. "From
automatic uploading to geotagging to sharing on the go, we've aimed to help
everyday photographers save their memories more often, share them more
quickly, and add more context to their collections."

Available immediately, the new Eye-Fi Anniversary Edition doubles

Dentistry: Are Dentists Ready for Unionization?

Disappointed by the American Dental Association, half of dentists say they are ready to unionize, finds a recent survey by The Wealthy Dentist. Of course, many support the ADA and think a dentists' union would be disastrous.

San Francisco, CA, November 11, 2008 --(PR.com)-- Half of dentists are ready for the profession to unionize, reveals a recent survey by dental marketing and dental practice management resource The Wealthy Dentist. Feeling trapped by dental insurance and abandoned by the American Dental Association, many dentists are ready for an organized dental union.

"You have got to be kidding me," said a Missouri prosthodontist. "Ever heard of the ADA?" Other dentists supported the dental association. "We have the ADA. If you want something done, put the pressure on them. The ADA is a very effective weapon on many fronts," declared a Florida dentist.

But others were sorely disappointed by the ADA. "The ADA can't get us national licensing," complained a New Jersey dentist. "The wimps running the dental societies certainly don't help when it comes to the insurers," said a New York dentist.

Dentists are often conservative, and many were turned off by the idea of a union. "What good would it do?" asked a California dentist. "Unionization would mean giving up each dentist's independence. Union workers have to abide by union rules instead of making their own policy and treatment decisions. If a dentist doesn't want to deal with insurance, he doesn't have to. It's entirely voluntary."

Dental insurance is one of the most important reasons dentists would join a union. "The insurance companies take far too much advantage of the dental industry, and do pretty much whatever they feel like knowing full well that organized dentistry, such as it is right now, doesn't have much in the way of clout to put up a fight against them," said a California dentist. Exclaimed another, "We should bring a class action lawsuit on those insurance companies!"

But not everyone hates dental insurance. "Insurance is God's gift to dentistry!" raved a dental consultant. "Without it, there would be a lot less dentistry getting done."

One dentist was so enthusiastic about the idea that he immediately volunteered to organize a dental union. "I got ripped off from all insurers: HMOs, PPOs, Medicaid, private insurers," he complained. "Put me in your organization and I will have 90% of dentists in our Union. I will travel the country. The time to fight back is now! Never give up! Let's fight!"

A Rhode Island periodontist suggested an alternative. "I'm not keen about unionization, but the best way would be for individual groups to form 'pods' under a single tax ID number. A group of almost 100 MDs in our state has been very successful with this, and it had an impact on an insurance company when the group threatened to pull out."

"Hey, is Dr. Hoffa looking for a new project?" joked Jim Du Molin, dental patient marketing guru and founder of dental management resource The Wealthy Dentist. "I must say, these results really surprise me. I know there's a lot of frustration with the ADA, but I wouldn't have expected dentists to say that unionization is the answer!"

CEREC Optispray for Fast and Accurate Digital Impressions and Quality CAD/CAM Restorations


CHARLOTTE, NC – October 29, 2008 – Sirona Dental Systems, LLC (Nasdaq: SIRO), the company that pioneered digital impressions more than 20 years ago and the world’s leading producer of dental CAD/CAM systems, recently introduced CEREC® Optispray, an advanced contrast medium in a convenient spray canister to enable easier and more precise optical impressions and, ultimately, the most esthetic and functional CAD/CAM-produced dental restorations possible.

“The use of a contrast medium has been providing CEREC users with highly accurate digital impressions that require a minimal number of scans for more than 20 years,” said Sirona Dental Systems, LLC USA President, Michael Augins. “Optispray simplifies this proven process and takes it to the next level.”

According to Dr. Sameer Puri of Tarzana, CA, “Eliminating the need for compressed air lines and clog-prone nozzles to deliver the contrast medium is a major breakthrough. Because the CEREC user is untethered, maneuverability is greatly improved for more accurate impressions – even for the most hard-to-reach posterior areas.”

Optispray was specially developed by Sirona’s in-house R&D department for use with the CEREC dental CAD/CAM system, and provides the following unique benefits:

• Consistency – Consistently easy, fast, and accurate application.

• Precision – Thanks to its thin, homogeneous contrast layer, Optispray delivers superior digital
impression results

• Ergonomic – Spray head can be turned or angled to the desired position, depending on application (mandible/maxilla).

• Patient Experience – Patients will appreciate Optispray’s pleasant spearmint scent and taste.


Preliminary reviews of Optispray have been very positive. According to Dr. Adamo Notarantonio of Huntington, NY, “As a CEREC owner, I have used all of the powdering devices on the market and I can honestly say, Optispray gives me the most consistent images, and is by far the easiest to use as well."

CEREC Optispray comes in 50ml canisters, including two application nozzles, has a two-year shelf life and is available exclusively through Patterson Dental Supply. For more information, call your local Patterson sales representative or visit www.cereconline.com.

3M ESPE Z100™ and Filtek™ Z250 Restoratives Receive Excellent Clinical Ratings


3M ESPE Z100™ and Filtek™ Z250 Restoratives Receive Excellent Clinical Ratings From The Dental Advisor

Restoratives offer long-lasting esthetics and minimal wear, proven through clinical history

ST. PAUL, Minn. – (Nov. 6, 2008) – 3M ESPE is proud to announce that both 3M™ ESPE™ Z100™ Restorative and 3M™ ESPE™ Filtek™ Z250 Universal Restorative have received excellent (+ + + + +) clinical ratings from The Dental Advisor, the highest achievable rating from this esteemed research- and educational-focused group.
Z100 restorative, an all-purpose, light cured composite with zirconia filler particles, was reviewed at 15 years and given a 96 percent clinical rating. To review Z100 restorative, almost 130 restorations that were placed in 1992-1993 were recently recalled. After 15 years, more than 80 percent of restorations exhibited no fracture or chipping, and while less than 20 percent showed some minor chipping, none of the restorations had required replacement. Evaluators from The Dental Advisor noted, “The wear resistance at 15 years was excellent, and in most cases wear was almost undetectable.” Additionally, very little shade change took place over the 15-year-period, with more than 70 percent of the restorations exhibiting excellent shade match.
Overall, evaluators believed that Z100 performed “exceptionally well over the 15-year monitoring period in both the anterior and posterior regions,” and, “The clinical performance of Z100 during this period met or exceeded all expectations.” Evaluators concluded: “Even though many new composites have since been introduced, Z100 has proven itself to be in a class of its own.”
Filtek Z250 universal restorative, a direct universal composite for anterior and posterior use, was reviewed at nine years and given a + + + + + rating. To review Filtek Z250 universal restorative, more than 560 restorations were recalled and evaluated. Results showed that almost 95 percent of restorations showed no chips or fractures. Additionally, 98 percent were rated very good to excellent in terms of esthetics, with restorations remaining smooth with stable color. The Dental Advisor evaluators stated, “The appearance of these restorations has rated consistently high for the past nine years.”
Nearly 90 percent of the restorations possessed no marginal discoloration at recall. Evaluators noted, “While staining at the margins can be predicted to increase over time, the ratings in this category have remained stable.” Evaluators also affirmed that “[Z250] is performing well not only in the anterior region, but also under occlusal load in posterior Class I and Class II situations,” and conclude, “It is an excellent choice for durable, esthetic restorations in anterior and posterior teeth.”
Ratings from The Dental Advisor were given in the clinical categories of resistance to fracture, esthetics, wear resistance, and resistance to marginal discoloration.
