ST. PAUL, Minn. – (September 1, 2010) 3M ESPE announces the launch of RelyX™ Unicem 2 Automix Self-Adhesive Resin Cement. This new material represents the next generation of self-adhesive resin cements and builds upon the long-term experience gained from its predecessor, combining convenience with reliable clinical performance. The cement will be available in an automix syringe with various application tips.

The newcomer is based upon the same chemistry as RelyX™ Unicem Self-Adhesive Universal Resin Cement, the most clinically proven self-adhesive cement worldwide. It has been applied more than 50 million times and was subject to numerous clinical and laboratory studies. This year, The Dental Advisor awarded RelyX Unicem Cement the “2010 Top Long-term Performer,” which is only one of many awards the cement has received. RelyX Unicem 2 Automix Cement follows in the footsteps of its predecessor, but the enhanced formula provides even better color stability, bond strength and moisture tolerance. It also offers low post-operative sensitivity and high long-term stability. In addition, excess cement can be removed quickly and easily.

RelyX Unicem 2 Automix Cement’s enhanced formulation offers even more convenience due to its automix delivery system. The syringe extrudes the ready-mixed cement through mixing tips, which are available in different sizes: regular mixing tips for standard applications, endo tips ensuring a safe and void-free procedure when working in the root canal and special intra-oral tips for the cementation of inlays and onlays. As with the first-generation cement, the need for any pre-treatment of the tooth, such as etching, priming and bonding, is eliminated.

RelyX Unicem 2 Automix Cement is suited for the permanent cementation of all-ceramic, composite or metal inlays, onlays, crowns and bridges, as well as posts and screws. It can also be used to cement restorations to implant abutments, as well as Maryland, inlay and onlay bridges.

Return From Lecturing in Kiev Ukraine

I am just settling back in from 3 days of lecturing at the Global Dental Congress Dent Life exhibition in Kiev Ukraine.  I enjoyed the opportunity to discuss dentistry with dentists who really want to learn. Most of the dentists do not speak English and all the lectures and hands on had translators present. It was a wonderful way to interact with colleagues from around the world. There were presenters from the US, UK, India, Hungary and the Ukraine.

I was able to introduce the participants to Kerr's Vertise Flow and Dentsply's SDR. Both of these products were new to the Ukraine and the participants were the first in their country to try the materials. My sincere thanks to both the local representatives of the aforementioned companies. Participants also got to try Greater Curve Bands for making Class composite contacts.

So now back my practice. Then later this week at NYU, I will be lecturing to foreign dentists as part of the "Current Concepts In American Dentistry" series.

Letter to Electric Dental Handpiece Manufacturers Regarding Reports of Overheating and Patient Burns

NOTICE of Safety Concern for Electric Dental Handpieces and Accessories

Certified Mail – Return Receipt Requested

August 20, 2010
Dear __________:
On December 12, 2007, the U.S. Food and Drug Administration (FDA) posted a public health notification alerting the public that the Agency had received reports of patient burns from electric dental handpieces. Since this communication, the FDA has received numerous additional reports, some detailing serious patient injuries, including third degree burns.
We are requesting your assistance in correcting the problems associated with patients being severely burned from overheating electric dental handpieces during dental procedures. We are also reminding you of your responsibilities as a manufacturer to comply with FDA requirements for medical devices including requirements under the Medical Device Reporting (MDR) rule, 21 CFR Part 803, to address this public health issue.

Background Information

Patients have been severely burned when electric dental handpieces have overheated during dental procedures. Some patients had third degree burns which required reconstructive surgery. Burns may not be apparent to the operator or the patient until after the tissue damage has occurred, because the anesthetized patient cannot feel the tissue burning and the handpiece housing insulates the operator from the heated attachment. Although the reported burns have occurred during cutting of tooth and bone, tooth extraction and other dental surgical procedures, overheating could occur during any dental procedure.
With high and low speed air-driven handpieces, sluggish handpiece performance will alert the dental practitioner to maintenance issues such as a dull bur or worn or clogged gears or bearings. A poorly maintained electric handpiece does not provide a similar warning that maintenance is needed. Instead, if an electric handpiece is worn, damaged or clogged, the electric motor sends increased power to the handpiece head or attachment in order to maintain handpiece performance. This increased power can rapidly generate heat at the head of the handpiece attachment. Because the heat buildup is so rapid, and is efficiently conducted through the metal handpiece, a burned patient may be the first indication of handpiece problems that the practitioner receives.

Factors That May Contribute to Adverse Events

  1. The labeling may not establish or adequately communicate a proper maintenance schedule;
  2. Users may not be aware that improperly maintained, damaged or worn devices have the potential to overheat without warning;
  3. Users may continue to use these products even after the device has overheated because they may not easily perceive it is approaching dangerous temperatures;
  4. Prescribed start up checks designed to alert the user of device failure by overheating may not realistically recreate the operating parameters that may cause overheating.

Actions to Address the Potential for Burns from Electric Dental Handpieces

  1. Records Review--Review your complaint records to identify reports and root causes of an overheating hazard. Review your adverse event files to evaluate whether your device is dangerous to health if used as suggested in the labeling. Using this information, verify that your risk management plan adequately addresses burn hazards.
  2. Human Factors--Ascertain whether dental professionals’ understanding of your labeling and the feasibility of performing the required maintenance of your product is adequately understood. Refer to the Guidance for Industry - Medical Device Use-Safety: Incorporating Human Factors Engineering into Risk Management issued July 18, 2000, for information about human factors and medical devices .
  3. Risk Mitigation--Consider the risk mitigation steps below (from most desirable to least desirable).
    1. Eliminate overheating through design modification.
    2. Protect or guard against overheating through design modification such as an overheating alarm.
    3. Warn the operator about overheating through warning labels.
    4. Train and instruct operators to avoid the hazard.
    5. Modify use of the device to preclude the hazard.
In addition to the activities referenced above, the FDA continues to believe that improved product labeling and educational outreach is important. However, based on the continuing adverse event reports of patient burns, the FDA believes labeling and outreach alone cannot sufficiently mitigate the occurrence of patient burns.

Reporting to the FDA

As a manufacturer of these devices, you are responsible for compliance with the requirements of the medical device reporting (MDR) rule. These requirements include reporting to FDA deaths and serious injuries that your device may have caused or contributed to and certain device malfunctions, and establishing and maintaining adverse event files.
To ensure that relevant manufacturers receive this information, attached for your signature is an acknowledgement form. Please check all appropriate lines and return the form to acknowledge receipt of this letter and confirm your status as an electric dental handpiece and/or accessories manufacturer.
Send a copy your communication to: Mr. Gregory W. O’Connell, Acting Director, Division of Enforcement A, Office of Compliance, 10903 New Hampshire Avenue, WO66-3516, Silver Spring, Maryland, 20993.
If you have questions relating to this matter, please feel free to call Mr. O’Connell at
(301) 796-5770, or log onto our web site at www.fda.gov for general information relating to FDA medical device requirements.
Sincerely yours,
Timothy A. Ulatowski

Asthma And Cavities Both Common In Kids But Not Linked

There is no apparent link between asthma and tooth decay, according to a study published in the September 2010 issue of the Journal of the American Dental Association.

"Is There a Relationship between Asthma and Dental Caries?: A Critical Review of the Literature" examined the 27 separate studies which looked for a link between asthma and cavities that were reported in 29 papers published between 1976 and March 2010.

"The notion that there is a link between asthma and tooth decay may have its origin in anecdotal statements by emergency room workers who see children with poorly managed asthma. These children could also be more likely to have poorly managed dental conditions, and therefore tooth decay. It's reasonable to believe that poor clinical management may be associated with both conditions, not the asthma that is causing the cavities," said Gerardo Maupomé, B.D.S., M.Sc., Ph.D., professor of preventive and community dentistry at the Indiana University School of Dentistry and a Regenstrief Institute affiliated scientist. He is the first author of the new JADA study.

"We found little evidence to suggest that asthma causes tooth decay. In fact, the two largest studies we reviewed found that children with asthma appear to have fewer cavities than others. This may be because their parents are used to taking them to health-care providers, and routinely bring them to the dentist," said Dr. Maupomé.

The large number of variables involved, including severity of asthma symptoms and the variety of types of treatment for the disease, has made it difficult to unequivocally determine whether there is a causal link between the two.

While not apparently associated, tooth decay and asthma are the two most prevalent chronic childhood diseases in the United States.

Routine home and professional dental care are critical for all children. Parents of children with asthma do not need to be concerned about an increased risk of tooth decay but Dr. Maupomé points out that children who use nebulizers to control their asthma may be inadvertently increasing their frequency of exposure to sugars because these nebulizers use fructose to deliver therapy. The frequency and the amount of certain sugars consumed are major factors leading to cavities.

He also recommends that children who are mouth breathers or who have mouth dryness be checked periodically by their dentists. These conditions may be associated with asthma but they are also found in children who do not have asthma. Many medications used for the long term (such as asthma medications) have been found to reduce the amount of saliva, which is the first protection of teeth.

In addition to Dr. Maupomé, the study was authored by Jay D. Shulman, D.M.D., M.A., M.S.P.H. of Baylor College of Dentistry; Carlo Eduardo Medina-Solis, B.D.S., M.C., of the Instituto de Ciencias de la Salud de la Universidad Autónoma del Estado de Hidalgo in Mexico; and Oyebola Ladeinde, B.D.S., M.S. of the IU School of Dentistry.

The study was funded by the Oral Health Research Institute of the Indiana University School of Dentistry. Both are located on the campus of Indiana University-Purdue University Indianapolis.

New Chemical Surface Improves Compatibility Of Dental Implants

New Chemical Surface Improves Compatibility Of Dental Implants

15 Sep 2010  

Dental implants have offered a successful way to restore teeth for more than 20 years. New challenges for improving the process include shortening the time to restore functionality and meeting aesthetic demands. Altering implant surfaces to help promote bone integration is one solution. SLActive, a new chemically-modified surface for titanium, the standard material of which implants are constructed, has shown positive results in this area.

An article in the August issue of the Journal of Oral Implantology reports a 98.2% success rate for SLActive at dental patients' one-year follow-up. A noninterventional study was conducted to compare these results with previous findings of high survival and success rates among the same type of implants in a controlled clinical trial.

In this noninterventional study, results were obtained under common dental practice conditions where patient selection was not restrictive and technique was not controlled. Thirty dental clinics in Italy participated, and 226 patients were treated. Patients presented with a variety of risk factors, and both early (48 hours to 3 months) and traditional (3 to 6 months) loading of the implant was performed.

Osseointegration-the connection between living bone and artificial implant-can determine stability of the implant over time. Surface properties of the titanium implant, such as topography and roughness, can assist the chemical and biological interface that occurs in the early stages of healing and thus influence the long-term outcome.

The 98.2% success rate of this study was similar to that reported in formal clinical trials. The high success rate in both studies shows that the SLActive implant surface can be safely used with consistent, predictable results. Patients can expect integration of their implants that restores functionality for chewing and speech as well as aesthetics.

Full text of the article, "A Noninterventional Study Documenting Use and Success of Implants With a New Chemically Modified Titanium Surface in Daily Dental Practice," Journal of Oral Implantology, Volume 36, No. 3, 2010, is available here.

Induction of Pluripotent Stem Cells from Human Third Molar Mesenchymal Stromal Cells

Induction of Pluripotent Stem Cells from Human Third Molar Mesenchymal Stromal Cells



  1. September 17, 2010 The Journal of Biological Chemistry, 285, 29270-29278.

Abstract

The expression of four transcription factors (OCT3/4, SOX2, KLF4, and MYC) can reprogram mouse as well as human somatic cells to induced pluripotent stem (iPS) cells. We generated iPS cells from mesenchymal stromal cells (MSCs) derived from human third molars (wisdom teeth) by retroviral transduction of OCT3/4, SOX2, and KLF4 without MYC, which is considered as oncogene. Interestingly, some of the clonally expanded MSCs could be used for iPS cell generation with 30–100-fold higher efficiency when compared with that of other clonally expanded MSCs and human dermal fibroblasts. Global gene expression profiles demonstrated some up-regulated genes regarding DNA repair/histone conformational change in the efficient clones, suggesting that the processes of chromatin remodeling have important roles in the cascade of iPS cells generation. The generated iPS cells resembled human embryonic stem (ES) cells in many aspects, including morphology, ES marker expression, global gene expression, epigenetic states, and the ability to differentiate into the three germ layers in vitro and in vivo. Because human third molars are discarded as clinical waste, our data indicate that clonally expanded MSCs derived from human third molars are a valuable cell source for the generation of iPS cells.

Survey of Tobacco Control Among Florida Dentists

Survey of Tobacco Control Among Florida Dentists

DOI: 10.1007/s10900-010-9299-5

Abstract


Cigarette smoking contributes to the largest number of preventable deaths with a recent report estimating that nearly 5 million annual deaths worldwide and 400,000 in the United States were attributed to cigarette smoking. Dentists, in particular, are in a unique position to educate their patients about the health effects of tobacco. Tobacco cessation knowledge, behaviors, and compliance of Florida dentists were assessed using survey methodology. The survey was administered to a random sample of 6,000 dentists, which was provided by the Florida Department of Health. The survey inquired about (1) general demographic information, (2) Ask, Advise, Assess, Assist, and Arrange behaviors, (3) barriers to the incorporation of tobacco cessation activities, and (4) willingness to participate in further training. A large majority of dentists (88%) are not familiar with the concept of the Ask, Advise, Assess, Assist, and Arrange behaviors when asked directly. When asked about each individual component of this approach, however, dentists had much higher response rates. Dentists were best at routinely asking (59%), advising (46%), & assessing (32%) their patients about their smoking. However, they were much less helpful when assisting and arranging follow-up (70% stated that they never arrange follow-up). This study discovered that the majority of dentists who counsel patients spend only 1–4 min. Sixty-six percent of the dentists surveyed were willing to receive specific training, with 50% preferring an online course and 42% preferring a continued education course.

BPA-free Sealants

Recently the media has regenerated the hype about BPA in sealants. Just to let everyone know there are BPA free sealants. Here is a press release about one of them.  MJ

WATERTOWN, MA:  September 13, 2010— The application of dental sealants does not need to expose children to BPA. Safe, approved, BPA-free alternatives are available to dentists and their patients.

Dental sealants are routinely applied to children’s teeth to help prevent cavities. While almost all resin-based sealants contain derivatives of bisphenol A (BPA), a controversial chemical that has been linked to health risks, there is one safe exception without BPA or BPA derivatives: Embrace WetBond Pit & Fissure Sealant (Pulpdent Corporation, Watertown, MA).

A study published online Sept 6th in the journal Pediatrics assessed BPA exposures from dental materials and the potential health risk to patients. While the authors did not recommend a ban of these products, they recommended that precautions be taken to reduce BPA exposure during sealant application and said that the development of BPA–free dental materials should be a priority.

Embrace WetBond Pit & Fissure Sealant is the only resin-based sealant that contains no BPA and no BPA derivatives. “This morning alone we received five calls about this issue,” says Fred Berk of Pulpdent, manufacturer of the popular Embrace product. “We’ve been making a BPA-free sealant for nine years. There’s no reason for parents to have to choose between protecting their child’s teeth and protecting their overall health.”

Research with laboratory animals has linked BPA exposure to heart health issues, and increased risk for cancer and diabetes, and hyperactivity. A study by the National Toxicology Program (NTP) of the National Institutes of Health evaluated the possible effects of exposures to BPA on human development. The NTP concluded that there was some concern for effects on the brain, behavior, and prostate gland in fetuses, infants, and children. 

Experts are continuing to study BPA and its impact on human health. In the meantime, most experts are advising people to minimize exposure whenever possible.

Pulpdent manufactures high-quality products for the dental profession, including adhesives, composites, sealants, cements, etching gels, calcium hydroxide products, endodontic specialties, and bonding accessories.  For more information, call 800-343-4342 or visit www.pulpdent.com.

Clinician- and patient-reported long-term evaluation of screw- and cement-retained implant restorations: a 5-year prospective study

Clinical Oral Investigations
DOI: 10.1007/s00784-010-0460-4

Sami Sherif, Srinivas M. Susarla, Jae-Woong Hwang, Hans-Peter Weber and Robert F. Wright

Abstract
The purpose of this study was to evaluate the survival and success of screw- versus cement-retained implant crowns over a 5-year period. This was a multi-center prospective cohort study, consisting of patients who had ≥1 dental implant placed and restored in the anterior maxilla over a 5-year period. The primary predictor variable was the type of restoration (screw- versus cement-retained). The outcome variables were clinician- or patient-reported measures related to soft tissue and restoration quality. Descriptive and bivariate statistics were computed to compare the screw- versus cement-retained groups. Kaplan–Meier statistics were computed for implant survival. Information was collected for 102 patients who had 214 implants placed during the study period. Complete data, amenable to analysis, were available for 99 (97.1%) patients and 193 (90.2%) implants. The restorations were approximately evenly divided between screw- (53.4%) and cement-retained (46.6%). Approximately 49% of patients in the sample were female; the sample's mean age was 47.3 ± 13.9 years; each patient had an average of 2.0 ± 1.0 implants placed and restored. The mean time from prosthesis placement (definitive) to study endpoint was 61.9 ± 10.6 months. The overall implant survival rate was 96.4%, with no statistically significant difference in survival between the screw- and cement-retained groups (p = 0.45). The majority of clinician- and patient-assessed outcomes were similar. The results of this study indicate that for the majority of clinician- and patient-assessed success parameters screw- and cement-retained restorations are equivalent in the anterior maxilla.

Evaluation of the effects of CO2 laser on debonding of orthodontics porcelain brackets vs. the conventional method

Evaluation of the effects of CO2 laser on debonding of orthodontics porcelain brackets vs. the conventional method 

DOI: 10.1007/s10103-010-0820-y

Abstract


Debonding of ceramic brackets due to their high bond strength and low fracture toughness is one of the clinician’s complications. The purpose of this study is to evaluate the effect of a laser on shear bond strength, site of debonding, and ARI index during debonding of ceramic brackets and then compare it to the conventional method used for this procedure. Thirty polycrystalline alumina (G & H Series, Germany) brackets were bonded to 30 intact extracted first and second maxillary premolars and stored in a 1% thymol solution. A chemically cured orthodontic composite resin (No-mix, Unitek, USA) was used for bonding the brackets to the enamel surface on all teeth. All brackets were positioned 4 mm from the incisal edge of the teeth with an orthodontic bracket-positioning device. Then the teeth with bonded brackets were embedded in auto-polymerized polymethylmethacrylate (2.2.3 cm) blocks using a special device to make their slots horizontally parallel. These 30 teeth were then divided into two subgroups: control or no-lased (n = 15) and super pulse CO2 laser (n  = 15). To characterize the peak of SBS in two groups, we used an Instron machine while its blade was moving at a constant speed of 1 mm/min. For evaluating the site of debonding and the adhesive remnant index (ARI index), a light microscope and the Photoshop program were used. Means and standard deviations of the SBS in two subgroups shows that in the control group, the teeth have definitely higher values in comparison to the experimental group. The results of the two groups drew no substantial differences with respect to the surface of debonding, which was mostly within the adhesive. However, observing the results of ARI presented a significant distinction between the control and experimental group. This index denoted that the debonding site in the control group was closer to the enamel adhesive interface and, consequently, the rate of enamel damage in this group would be greater. The present study shows that a CO2 laser has the potential to replace the conventional method for debonding ceramic brackets due to less debonding force and more adhesive remnant index on the tooth surface.

Flapless and Traditional Dental Implant Surgery: An Open, Retrospective Comparative Study


 Volume 68, Issue 9, Pages 2299-2306 (September 2010)





Flapless and Traditional Dental Implant Surgery: An Open, Retrospective Comparative Study

Paul Rousseau, MDCorresponding Author Informationemail address
Purpose
Osseointegrated dental implantation is traditionally performed by a flap approach that involves soft tissue flap reflection, but this technique is associated with several drawbacks. Conversely, the flapless method requires only minimal removal of soft tissue but is not suitable for all patients. The objective of this study was to compare the flapless (FL) method of implant placement with the traditional flap (TR) method with regard to achievement of success, change in bone level, and overall safety.
Patients and Methods
In this single-center, open, retrospective, investigator-driven, nonrandomized, comparative study, patients were pre- or intraoperatively assigned to the FL or TR treatment. The primary success criteria were the absence of mobility, radiolucency, pain, and infection.
Results
The FL method was applied to 174 implants (46%) in 121 patients and the TR method to 203 implants (54%) in 98 patients. At visit 1, implantation was rated successful in 171/174 (98.3%) implants with the FL method and in 200/203 (98.5%) with the TR method. Success rate remained constant until visit 2. The difference between the 2 groups in the rate of success was not significant. Similarly, no significant difference was observed for mean time to last follow-up for success.
Conclusions
Based on pre- or intraoperative decision-making, patients eligible for FL surgery can benefit from a less straining procedure without affecting the high success rate of dental implant surgery. The FL approach is a predictable procedure when patient selection and surgical technique are appropriate.

3M ESPE announces the launch of RelyX™ Unicem 2 Automix Self-Adhesive Resin Cement

Inventor of Self-Adhesive Resin Cements Introduces Next Generation

Enhanced formulation provides increased convenience, better color stability, bond strength and moisture tolerance


ST. PAUL, Minn. – (August 30, 2010) 3M ESPE announces the launch of RelyX Unicem 2 Automix Self-Adhesive Resin Cement. This new material represents the next generation of self-adhesive resin cements and builds upon the long-term experience gained from its predecessor, combining convenience with reliable clinical performance. The cement will be available in an automix syringe with various application tips.


The newcomer is based upon the same chemistry as RelyX Unicem Self-Adhesive Universal Resin Cement, the most clinically proven self-adhesive cement worldwide. It has been applied more than 50 million times and was subject to numerous clinical and laboratory studies. This year, The Dental Advisor awarded RelyX Unicem Cement the “2010 Top Long-term Performer,” which is one of many awards the cement has received. RelyX Unicem 2 Automix Cement follows in the footsteps of its predecessor, but the enhanced formula provides improved color stability, bond strength and moisture tolerance. It also offers low post-operative sensitivity and high long-term stability. In addition, excess cement can be removed quickly and easily.

RelyX Unicem 2 Automix Cement’s enhanced formulation offers more convenience due to its automix delivery system. The syringe extrudes the ready-mixed cement through mixing tips, which are available in different sizes: regular mixing tips for standard applications, endo tips ensuring a safe and void-free procedure when working in the root canal and special intra-oral tips for the cementation of inlays and onlays. As with the first-generation cement, the need for any pre-treatment of the tooth, such as etching, priming and bonding, is eliminated.

RelyX Unicem 2 Automix Cement is suited for the permanent cementation of all-ceramic, composite or metal inlays, onlays, crowns and bridges, as well as posts and screws. It can also be used to cement restorations to implant abutments, as well as Maryland, inlay and onlay bridges.

With its combination of proven technology and innovative features, RelyX Unicem 2 Automix Cement is an exciting new material with the potential to further improve and simplify procedures in the dental practice.
