International Report: No Amalgam Bans in Effect

Dentists around the world are using amalgams (silver fillings)
every day to fill decayed teeth, despite some erroneous news reports
stating that many countries have banned the use of amalgams.
International dental experts meeting recently at the American Dental
Association (ADA) headquarters in Chicago discussed the use of amalgam
in their respective countries.

Sweden is often cited as an example of a country that has banned
amalgam, but that is not true, according to Professor Maud Bergman of
University. Professor Bergman said it is unlikely Sweden will ban the
use of amalgams in the near future. Nor do Sweden's neighbors, Norway
and Denmark ban the use of the filling material. Representatives from
Germany and the Netherlands also said amalgam is not banned in their
countries. Dr. Elmar Reich of Germany's University of Saarland said
that some limited restrictions on the use of amalgam may even be
loosened when the classification of amalgam changes in mid-1998 to a
medical device from its current designation as a therapeutic
agent. Dentists from South Africa, Australia, New Zealand, Japan and
Canada reported that amalgam is not banned in their countries either.
Although the Canadian government has recommended some restrictions on
the use of amalgam, the Canadian Dental Association (CDA) has requested
that the government provide scientific documentation to back up some of
the recommendations that the CDA is questioning.

The World Health Organization, FDI World Dental Federation and the ADA
all support the continued use of dental amalgam as a safe, durable and
cost-effective material to restore teeth based on current scientific
knowledge. There is currently no credible scientific evidence that
exposure to mercury from amalgam restorations poses a serious health
risk in humans, except for the exceedingly small number of allergic
reactions. In 150 years of use, there have been only about 100
documented cases of allergic reactions to amalgam in the dental
literature. A joint WHO/FDI meeting is scheduled in Geneva,
Switzerland, in March, 1997, to review the latest scientific evidence on
the safety of dental amalgam.

Bitemark evidence and analysis should be approached with caution, according to UB study

BUFFALO, N.Y. -- Against the backdrop of last week's Congressional hearing into the future of forensic science, researchers from the University at Buffalo's Laboratory for Forensic Odontology Research in the School of Dental Medicine, have published a landmark paper on the controversial topic of bitemark analysis.

The Congressional hearing focused on the findings of a National Academy of Sciences (NAS) report on the scientific basis of forensic disciplines. Among the pattern evidence fields (fingerprints, tool marks, etc.) that were reviewed in the NAS report, bitemark analysis received critical commentary. During the hearing, Innocence Project co-founder Peter Neufeld introduced Roy Brown, wrongfully convicted on bitemark evidence and later exonerated through DNA analysis.

In anticipation of the NAS report, the new UB study published in the Journal of Forensic Sciences challenges the commonly held belief that every bitemark can be perpetrator identified.

"Bitemark identification is not as reliable as DNA identification," explains the study's lead author Raymond G. Miller, D.D.S., UB clinical associate professor of oral diagnostic sciences.

"With DNA, the probability of an individual not matching another can be calculated," he says. "In bitemark analysis, there have been few studies that looked at how many people's teeth could have made the bite."

Miller's co-authors include UB's Peter J. Bush; Robert Dorion, D.D.S., DABFO, UB adjunct professor of oral diagnostic sciences; and Mary A. Bush, D.D.S., UB assistant professor of restorative dentistry. Dorion is the editor of the only comprehensive textbook on the subject of bitemarks in forensic science, Bitemark Evidence: A Color Atlas and Text, and is currently the odontology section representative to the board of directors of the American Academy of Forensic Sciences.

The current study investigated three main questions: is it possible to determine biter identity among people with similarly aligned teeth; is it possible to determine how many individuals from a larger sample might also be considered as the biter; and, if there is bite pattern distortion, is it enough to rule out a specific biter while still including a non-biter?

To answer these questions, the researchers gathered 100 stone dental models (replicas of the dentition), which were measured and divided into 10 groups based upon the misalignment patterns of the teeth. After randomly selecting one model from each of the 10 groups, the researchers impressed bitemarks on cadaver skin. After the bitemarks were created, they were then photographed and the indentations were compared to the dentitions using overlays created with photographic software.

The authors are one of the first to use a human skin model rather than animal models or non-elastic biting substrate, such as wax or Styrofoam. Current human subject restrictions limit experimentation on living subjects.

"Living bitten tissue may bleed or bruise," explains Miller. "The initial bitemark indentations rebound shortly after infliction often leaving a diffuse bruising that may be difficult to measure accurately. The indentations produced in our study represented the best conditions for measurement."

The results indicated that when dental alignments were similar, it was difficult to distinguish which set of teeth made the bites. Distortion noted in the bitemarks allowed matches even from different alignment groups. Therefore, the researchers concluded that bitemarks should be very carefully evaluated in criminal investigations where perpetrator identity is the focus of a case.

As Miller notes, "In the past 10 years, the number of court cases involving bitemark evidence that have been overturned led us to question the reasons for the erroneous bitemark identification. It's important to recognize the serious consequences of a misidentification for the accused, the victim, the families involved, the justice system and the possibility that the perpetrator is still at large."

Body's immune system response to dental plaque varies by gender and race

INDIANAPOLIS – Will neglecting to brush your teeth damage more than just your smile? Can failing to attack dental plaque increase your risk of heart damage?

The answer to both questions may be yes if you are male and black, an Indiana University School of Dentistry study published in the current issue of the Journal of Dental Research reports.

The researchers, led by Michael Kowolik, B.D.S., Ph.D., professor of periodontics and associate dean for graduate education at the IU School of Dentistry on the campus of Indiana University-Purdue University Indianapolis, studied 128 black and white men and women and found that dental plaque accumulation did not result in a change in total white blood count, a known risk factor for adverse cardiac events. However, in black males the researchers noted a significant increase in the activity of neutrophils, the most common type of white blood cell and an essential part of the immune system.

Unlike most other studies that attempt to understand the link between oral inflammatory disease and heart disease risk, these study participants did not have periodontal disease. They were healthy individuals who by the study design were asked to neglect oral hygiene.

"We are talking about healthy people who simply neglect oral hygiene and if they were male and black, we found a response from their white blood cells, or neutrophils, that might be a cause for concern," said Dr. Kowolik.

"If you get a bacterial infection anywhere in the body, billions of neutrophils come flooding out of your bone marrow to defend against the intruder. Our observation that with poor dental hygiene white blood cell activity increased in black men but not black women or whites of either sex suggests both gender and racial differences in the inflammatory response to dental plaque. This finding could help us identify individuals at greater risk for infections anywhere in the body including those affecting the heart," he said.

Physicians have known for about a quarter of a century that one of the principal risk factors for a heart attack is an elevated white blood cell count. "While we did not observe higher white blood cell counts as the result of dental plaque accumulation, the increased activity of white blood cells, which we did find, may also carry a higher risk for heart disease," he added.


"Neutrophil Response to Dental Plaque by Gender and Race" appears in the August 2009 issue of the Journal of Dental Research and adds to the body of evidence that dental hygiene plays an important role in a preventive health program for the whole body.

Other authors of the study, which was supported by a grant from the National Institutes of Health, are Vivian Y. Wahaidi, B.D.S. of the IU School of Dentistry; Sheri A. Dowsett, B.Ch.D., Ph.D. of Eli Lilly and Company and the IU School of Dentistry; and George J. Eckert, M.A.S. of the Division of Biostatistics of the IU School of Medicine.

Located on the Indiana University - Purdue University Indianapolis campus, the Indiana University School of Dentistry is one of the oldest dental schools in the United States and has more than 11,000 living alumni who are pursuing careers throughout the nation and in more than 30 other countries. The only dental school in Indiana, it has educated about 85 percent of Indiana dentists.

‘Is that covered?’: 1 in 5 have no clue about dental benefits

‘Is that covered?’: 1 in 5 have no clue about dental benefits
September 22, 2009 by Jared Bilski

Employers should be wary of assuming that their employees have a grasp of the ins and out of their dental benefits, says this prominent study.

The “Dental Insights” study by MetLife uncovered some unsettling facts about employees’ knowledge of their dental benefits. The following findings should raise some red flags for most employers:

* Only 1 out of every 3 employees feel they have the info they need about their dental coverage to pick the right plan, and
* 1 out 5 employees say they have “no idea” what is/isn’t covered.

Luckily, the study also revealed what employers can do to ensure that their staffers are happy with the dental coverage being offered.

The key: A versatile education program. MetLife suggest companies educate employee about what is and isn’t covered by the dental plan (as well a utilization summary to help people see what they’ve seen so far); use oral health risk assessment to gauge where employees are at; and stress the connection between oral health and overall health

The Effect of Bleaching Agents on the Surface Topography of Ceramometal Dental Alloys

Journal of Prosthodontics
Published Online: 17 Sep 2009

The Effect of Bleaching Agents on the Surface Topography of Ceramometal Dental Alloys
Cherif A. Mohsen, BDS, MDSc, DDS


Purpose: To study the effect of bleaching agents on the surface topography of ceramometal alloys.

Materials and Methods: Three types of ceramometal alloys were used (gold, Ni-Cr, Co-Cr-Ti), and two types of bleaching agents (an agent intended for home use, one intended for use in the dental office) were studied. Forty-five specimens were constructed and divided according to the alloy type into three main groups, 15 specimens per group. Each group was further subdivided into three subgroups according to the type of bleaching agent used. The first subgroup (five specimens) was not subjected to any bleaching agent. The second and third subgroups were subjected to home and in-office bleaching agents, respectively.

Results: Au alloy showed the least surface roughness when subjected to either of the two bleaching agents. Ni-Cr alloys showed the highest surface roughness for both the control and home bleached subgroups, and Co-Cr-Ti alloy showed the highest surface roughness in the in-office bleached subgroup. No statistically significant difference was found between the control subgroup and the home-bleached subgroup for either the Au alloy or the Co-Cr-Ti alloy. For the two alloys, both the control and home-bleached subgroups were statistically different from the in-office bleached subgroups. There was a statistically significant difference between the Ni-Cr control subgroup and the other two bleached subgroups, while there was no difference between the two bleached subgroups. Results also showed that increasing the concentration of bleaching agents increased the surface roughness of all the tested alloys. There was a statistical difference between the Ni-Cr alloy and the other two alloys in all tested subgroups except the in-office bleached subgroup, for which no difference between the surface roughness of the Ni-Cr alloy and the Co-Cr-Ti alloy was found. Scanning electron microscopic examination revealed surface deteriorations in the two bleached subgroups for all tested ceramometallic alloys.

Conclusion: Surface topographic alterations occurred as a result of the application of bleaching agents. These alterations increased with the increase of the carbamide peroxide concentration.

Variability of Mechanical Torque-Limiting Devices in Clinical Service at a US Dental School

Michael S. McCracken, DDS, PhD, Lillian Mitchell, DDS, Rashmi Hegde, BDS, MS, & Mahendra D. Mavalli, BDS, MS

Journal of Prosthodontics
Published Online: 17 Sep 2009


Purpose: The purpose of this study was to measure the variability of torque produced by a population of mechanical torque-limiting devices in clinical service in a US dental school. The torque-limiting devices were divided into two categories according to their mode of action: toggle-type and beam wrenches. Proper action of these devices is essential for calibrated delivery of preload to implant prosthetic screws.

Materials and Methods: Seventeen torque-limiting devices (35 Ncm) were obtained from graduate prosthodontic, predoctoral, and faculty practice clinics. Nine of these were toggle-type devices, and eight were beam-type wrenches. Torque from each wrench was measured using an MGT electronic torque meter. Wrenches were tested in two modes, slow (over 4 seconds) and fast (over 1 second).

Results: Toggle-type torque wrenches produced a mean (± SD) torque of 38.1 ± 16.0 Ncm; beam-type wrenches produced 32.8 ± 1.1 Ncm. These results were not significantly different. When tested in fast mode (1 second), toggle-type wrenches produced 28.0 ± 9.6 Ncm; in the slow mode (4 seconds) they produced significantly more force, 36.6 ± 14.0 Ncm (p < 0.001). Beam-type wrenches produced 33.2 ± 1.1 Ncm and 32.8 ± 1.1 Ncm in fast and slow modes, respectively.

Conclusions: Both types of wrenches tested were capable of producing accurate torque values; however, variability was higher in the toggle-type group. Some toggle-type torque wrenches in clinical service delivered unacceptably high torque values. It is recommended that clinicians calibrate toggle-type wrenches frequently. Torque wrenches should be activated slowly, over 4 seconds, when using a correctly calibrated toggle-type wrench.

Trimira Introduces the Identafi™ 3000 ultra for Oral Cancer Screening

I am supposed to be getting one of these newer units to try. Full report after I do. MJ

HOUSTON, TX: September 16, 2009 Houston-based Trimira™ LLC has introduced the Identafi™ 3000 ultra, an upgraded version of the small, cordless, handheld oral cancer screening device they introduced in March 2009. The ultra features enhancements such as nickel-plating, double the auto-fluorescent power, and both hardware and software upgrades. The device uses a three-wavelength optical illumination and visualization system to allow dental professionals to catch early cancers not visible to the naked eye.

The Identafi 3000 ultra features the same proprietary, patented multi-spectral light wavelengths as the popular Identafi 3000. A study published in the May 2009 issue of Cancer Prevention Research found that the excitation wavelength delivered by the Identafi 3000 (and Identafi 3000 ultra) is optimal for discriminating between neoplastic and non-neoplastic lesions. New diodes deliver twice the auto-fluorescent power to further improve visualization.

The Identafi 3000 ultra uses three different wavelengths of light to excite oral tissue in distinct and unique ways. Biochemical changes can be observed with fluorescence, while morphological changes can be observed with reflectance. This multiple wavelength technology identifies abnormal tissue with more accuracy than a single color wavelength.

Nickel plating has been added to the Identafi 3000 ultra to boost electrical conductivity, improve durability, and provide a smoother feel. Trimira has also made hardware and software upgrades to maximize the device’s performance.

The Identafi 3000 ultra is supported by a national team of trained sales representatives and is available through most major U.S. dental dealers.

TRIMIRA LLC is a subsidiary of Remicalm LLC, a privately held medical diagnostic and imaging device company. Other subsidiaries are working on screening and diagnostic devices for skin, cervical, gastrointestinal, and bladder cancers. Remicalm's core technologies are based on high-speed, high-resolution capabilities from its patented optical processing technology platforms and include the ability to read metabolic and physiologic differences in diseased and healthy tissue in the human body.

Dental problems common cause of ER visits

Dental problems common cause of ER visits
By John Fritze, USA TODAY

Just before 3 a.m., Sidney Lawhorn and his wife sit on a bed in the emergency department. She's wrapped in a white sheet to stay warm. He's nursing the toothache that prompted his hour-long drive here.

"I had a tooth pulled about 10 days ago and, yesterday, it got to hurting real bad, Lawhorn, 26, says, his speech slightly slurred by Novocain. "My dentist is on vacation. ... They told me if it got too bad to come up to the emergency room. It just got too bad, so I came up here. ... It's the only place I do come."

Dental visits are the fifth-most-common reason for a visit to the UVA Medical Center. Lawhorn says he doesn't have dental insurance or health insurance. That's part of the reason why he ends up in the emergency room a couple of times a year or, '"whenever something happens," he says. "A toothache's got to be about the worst thing there is."

Descriptive Study of the Longevity of Dental Implant Surgery Drills

Clinical Implant Dentistry and Related Research
Published Online: 9 Sep 2009

Olive F. L. Allsobrook, BDS;Jonathan Leichter, DMD;Douglas Holborow, BDS;Michael Swain, PhD,BDS,

Background: Atraumatic preparation of the osteotomy site is critical for osseointegration.

Purpose: This study aimed to investigate the effects of multiple usages of dental implant drills on bone temperature changes and to examine the cutting surfaces of these drills under a scanning electron microscope (SEM).

Materials and Methods: The implant osteotomy procedure was adapted to the experimental setting to simulate wear on implant drills by preparing bovine ribs using a constant drilling force. Thermocouples were placed in the specimens to record temperature changes. SEM images of the drills were taken, and elemental spectroscopic analysis was performed.

Results: Temperatures measured in the bone adjacent to the implant site did not exceed 27.7°C during the experiment. Spectroscopic elemental analysis indicated that two of the drills were of a stainless steel composition, and the other drill consisted of a tungsten carbide-coated stainless steel. The tungsten carbide-coated bur had the lowest overall drilling temperatures and showed the least surface corrosion and plastic deformation. SEM analysis showed degradation of the cutting surfaces of the burs although the plastic deformation and surface wear did not appear to affect the cutting temperatures. Surface corrosion was observed on the cutting surfaces.

Conclusions: Drills used for up to 50 osteotomies do not appear to elevate bone temperatures to a harmful level. However, drill corrosion is potentially important in determining the life span of implant burs.

Expasyl Gingival Retraction Paste, Now in Pleasant New Strawberry Flavor

Kerr is very excited to share with you Expasyl™ Strawberry – the newest version of our innovative Expasyl gingival retraction paste and a great alternative to packing cord. Expasyl Strawberry incorporates the same excellent hemostatic capabilities, safe retraction, patient comfort and other features of Expasyl—now in a new strawberry flavor for greater patient satisfaction, and packaging configurations that offer greater value for your practice. Here is the press release.

ORANGE, CA – July 24, 2009 – Expasyl gingival retraction paste now comes in strawberry flavor. This new version of Expasyl offers the same tissue management qualities—excellent hemostasis and atraumatic gingival retraction in a fraction of the time it takes to use cord—now in a pleasant new taste. A new high-value intro kit includes the lightweight ergonomic gun, new curved tips, and 60% more material than the original.
Expasyl significantly cuts retraction time, is less traumatic to surrounding tissue, and the composition of the material prevents bleeding and crevicular fluid from obscuring the detail of an impression. It contains a 15% concentration of aluminum chloride which constricts blood vessels and shrinks epithelial tissue, preventing residual bleeding and separating soft tissue from the dentition. This results in an open, dry sulcus which is the ideal environment for impression-taking. These same clinical benefits are also useful in final cementation of indirect restorations or any restorative procedure that occurs near or below the gumline.
A leading product evaluation service cites that over 90% of impressions received in dental labs today do not have a circumferential visible margin, indicating that soft tissue frequently obstructs the finish line in impressions. Fast, safe and painless, Expasyl is a one-of-a-kind solution to this problem, simultaneously stopping bleeding and expanding the sulcus, which allows impression material to accurately capture crisp margins for great-fitting restorations.
To learn more about Expasyl Strawberry or our broad portfolio of products, visit or call 800.KERR.123. To find out more about continuing education online and free CE credit, visit Kerr University at for upcoming live webcasts, on-demand video, and the latest CE articles.

Introducing Icon - the revolutionary treatment for incipient caries and white spot lesions…without drillin

ENGLEWOOD, NJ – DMG America introduces an entirely new, revolutionary approach to treating incipient caries—Icon, a caries infiltrant. Until now, dental professionals had only two options for treating caries: fluoride and other remineralization therapies, if caries were not too advanced; or the “wait and see” until it was time to “drill and fill” approach. Caries infiltration is a major breakthrough in micro-invasive technology that fills, reinforces, and stabilizes demineralized enamel without drilling or sacrificing healthy tooth structure.

“Icon represents a new category of dental products,” says Tim Haberstumpf, DMG America Director of Marketing. “It is the first product to bridge the gap between prevention (fluoride therapy) and caries restoration. Icon’s micro-invasive infiltration technology can be used to treat smooth surface and proximal carious lesions up to the first third of dentin (D-1). In just one patient visit, Icon can arrest the progression of early enamel lesions and remove white spot lesions.”

When a dentist discovers incipient caries that are beyond preventive therapies though too early for restorative treatment, Icon offers a simple alternative to the “wait and see” approach. With Icon, the dentist can offer immediate treatment without unnecessary loss of healthy tooth structure. Icon prevents lesion progression and increases life expectancy for the tooth. Icon also provides a highly esthetic alternative to microabrasion and other restorative treatments for cariogenic white spot lesions. White spot lesions infiltrated by Icon take on the appearance of the surrounding healthy enamel.

“The Icon infiltration system is simple and user friendly,” Haberstumpf says. “Total treatment time is about 15 minutes, so it saves patients time and frees up additional chairtime.”

After isolating the tooth with a rubber dam and placing wedges to separate the teeth, the tooth surface is prepared with a 15% HCL gel to open the pore system of the lesion body. Next, the surface is rinsed, dried with ethanol, and further dried with air. The Icon Infiltrant resin, which has a high penetration coefficient, is applied onto the lesion, excess material is removed, and the material is light cured. The manufacturer recommends applying a second layer of the infiltrant, followed by additional light curing.

The Icon kits provide everything necessary for treatment except the rubber dam, including specially designed dental wedges, patented perforated applicator tips for the materials, individual syringes filled with Icon-Etch, Icon-Dry (ethanol), Icon-Infiltrant, and both written and diagrammatic instructions. All syringes come in a special screw-type applicator to ensure the materials are gently and slowly extruded onto the tooth.

Change in surface hardness of enamel by a cola drink and a CPP-ACP paste.

I am a big believer in reminerilization and ozone treatments. MJ

OBJECTIVES: This in vitro study used surface microhardness to evaluate whether a paste containing casein phosphopeptide amorphous calcium phosphate (CPP-ACP) can reharden tooth enamel softened by a cola drink, and how different saliva-substitute solutions affect the enamel hardness. METHODS: Twenty-four bovine incisors, each tooth consisting of treatment and control halves, were immersed in a cola drink (Coke) for 8 min, then placed under a 0.4 mL/min drip with various saliva-substitute solutions. The saliva-substitute solutions were: saliva-like solution (SLS) with 1 ppm fluoride, SLS without fluoride, and Biotene mouthwash. CPP-ACP paste was applied to the treatment halves for 3 min at 0, 8, 24, and 36 h. Knoop microhardness measurements were performed at baseline, after the cola drink immersion, and after 24 and 48 h contact with saliva-substitute solution. RESULTS: Enamel hardness significantly decreased after immersion in cola drink (ANOVA, p<0.05). After contact with saliva-like solutions for 48 h, those treated with CPP-ACP paste were significantly harder than those untreated regardless of the presence of 1 ppm fluoride in the saliva-like solution (ANOVA, p<0.05). Biotene mouthwash significantly softened the enamel surface (ANOVA, p<0.05). Two-way ANOVA showed significant effects of the CPP-ACP paste application and types of saliva-substitute solutions on the changes in surface hardness of the softened enamel at a significance level of 0.05. CONCLUSION: The application of CPP-ACP paste with continuous replenishment of saliva-like solution for 48 h significantly hardened enamel softened by a cola drink. Biotene mouthwash softened enamel surface after 48 h contact.
