U.S. Supreme Court Declares the Patient Protection & Affordable Care Act Constitutional: What It Might Mean for General Dentistry

Chicago (June 28, 2012)—Today, the U.S. Supreme Court announced its decision on the constitutionality of the Patient Protection and Affordable Care Act (the Act). Academy of General Dentistry (AGD) President Jeffrey M. Cole, DDS, MBA, FAGD, issued the following statement:
“Although the Supreme Court found the Act to be constitutional, the decision does not address either the alternative provider program or the medical device tax. The AGD will continue its effort to urge Congress to repeal both programs. Meanwhile, a greater long-term concern might be the possible effect that the Court’s decision has on Congress’ ability to apply future penalties to the practice of dentistry.”
By redefining the penalty for violating an individual mandate upon residents of individual states as a federal tax, the AGD believes that the decision may significantly expand the power of Congress beyond the powers within the Commerce Clause. Essentially, it appears to allow Congress to expand its reach into penalization of residents, intra-state, or within each state, through the power of taxation.
“We are concerned about this expansion of Congressional power, because it may now allow federal control of the performance of dentistry through taxation. For example, the ruling may allow Congress to use taxation to compel what services are provided regardless of what state law allows,” states AGD Dental Practice Council Chair Richard Crowder, JD, DDS.
AGD Legislative & Governmental Affairs Council Chair Myron J. Bromberg, DDS, adds, “The power granted to Congress to penalize through taxation may significantly affect the future of the dental practice as we know it. It brings the federal government into the operatory between ourselves and our patients and that in itself may affect our ability to continue to deliver what we consider treatment to our patients.”

Google Docs- Offline Editng and iOS access

I use Google for a lot of things such as Gmail, Google Voice etc. One thing I was not suing was Google Docs because there were times such as when I was on a plane where it would not work. Well, Google  has updated their popular service to allow offline editing. So swing on by and take a look at Google Docs and Google Drive. Read the press release below. MJ

Announcing your two most requested features: offline document editing and Drive for iOS

In April, we introduced Google Drive, a place where you can create, share, and keep all your stuff. Today at the Google I/O conference we announced two new ways to get things done in the cloud: offline editing for Google documents and a Drive app for iPhone, iPad, and iPod touch.

Offline document editing

No internet connection? No big deal. With offline editing, you can create and edit Google documents and leave comments. Any changes you make will be automatically synced when you get back online.

You can enable offline editing from the gear icon in Google Drive and find more detailed instructions for getting set up in the Help Center. Note that you'll need the latest versions of Chrome or ChromeOS to edit offline. We're also working hard to make offline editing for spreadsheets and presentations available in the future.

Google Drive for iOS

We launched the Drive app for Android phones and tablets a few weeks ago, and starting today, Google Drive is available for your iPhone, iPad and iPod touch.

With the Drive app, you can open PDFs, photos, videos, documents and anything else stored in your Drive while you're on the go. You can also search all your files, add collaborators to documents, and make files available offline to view them even without an internet connection. For blind and low-vision users, the app also works great in VoiceOver mode. Learn more about what you can do with the app in our Help Center.

Imaging in vivo secondary caries and ex vivo dental biofilms using cross-polarization optical coherence tomography

Still waiting to see if an OCT caries scanner actually makes it to the dental market.  MJ
Dental Materials
Volume 28, Issue 7 , Pages 792-800, July 2012



Conventional diagnostic methods frequently detect only late stage enamel demineralization under composite resin restorations. The objective of this study is to examine the subsurface tooth–composite interface and to assess for the presence of secondary caries in pediatric patients using a novel Optical Coherence Tomography System with an intraoral probe.


A newly designed intraoral cross polarization swept source optical coherence tomography (CP-OCT) imaging system was used to examine the integrity of the enamel–composite interfaces in vivo. Twenty-two pediatric subjects were recruited with either recently placed or long standing composite restorations in their primary teeth. To better understand how bacterial biofilms cause demineralization at the interface, we also used the intraoral CP-OCT system to assess ex vivo bacterial biofilm growth on dental composites.


As a positive control, cavitated secondary carious interfaces showed a 18.2dB increase (p<0.001), or over 1–2 orders of magnitude higher, scattering than interfaces associated with recently placed composite restorations. Several long standing composite restorations, which appeared clinically sound, had a marked increase in scattering than recently placed restorations. This suggests the ability of CP-OCT to assess interfacial degradation such as early secondary caries prior to cavitation. CP-OCT was also able to image ex vivo biofilms on dental composites and assess their thickness.


This paper shows that CP-OCT imaging using a beam splitter based design can examine the subsurface interface of dental composites in human subjects. Furthermore, the probe dimensions and acquisition speed of the CP-OCT system allowed for analysis of caries development in children.

A Survey of US Dental Practices' use of Social Media.

Henry RK, Molnar A, Henry JC. A Survey of US Dental Practices' use of Social Media. J Contemp Dent Pract 2012;13(2):137-141.


Aim: Social media is becoming the way for businesses, including health care professionals, to communicate with consumers. The study examines the use of social media by dental practices in the US. Materials and methods: An electronic survey was sent to 22,682 dentists in the United States. The survey consisted of questions related to the use of social media in the dental practice. Data was analyzed using descriptive statistics and comparisons were made using a Fisher's exact test. Results: A total of 573 responses were received. Social media was used in 52% of dental practices, the most common being Facebook. The use of social media was most commonly for marketing purposes (91%). Dentists younger than 45 years old were more likely to use social media in their practice than dentists 45 years or older (p > 0.001). Conclusion: Dental practices actively use social media for marketing and communication. Many dentists are unsure how to measure the success of social media in their practice. Additional research is needed to measure the success of social media in a dental practice. Clinical significance: Social media is a common way practices market and interact with their patients. There are some difficulties in determining what appropriate content for social media is and how to evaluate the success.

New ZONEfree Temporary Dental Cement Uses Reflective Color Blending Nanofillers to Create Natural Looking Temporaries

I have been using ZONEfree and it is working well in my office. MJ

DUX Dental Introduces First Translucent Zinc Oxide Non-Eugenol Cosmetic Dental Cement

OXNARD, Calif., June 19, 2012 (GLOBE NEWSWIRE) -- DUX Dental is introducing a new temporary dental cement that contains prismatic color blending nanofillers that act like tiny beads of glass to reflect the color of any adjacent surface. The new product, called ZONEfree, is the only zinc oxide non-eugenol cosmetic cement that is translucent. Its unique formulation combines the esthetic benefits of reflective nanofillers and translucency, creating a natural look that blends with the color of the patient's own teeth, crowns or other surfaces around it. ZONEfree will be available for order through major dental dealers starting July 1st.

"The desire for a superior aesthetic result now overshadows the simple need to replace a broken tooth. Television, print media, and the successful esthetic results seen among friends and co-workers have raised the public's expectation about what they will get from their health care provider," said Michael Durda, vice president of clinical affairs of DUX Dental in Oxnard, Calif. "Because ZONEfree combines both reflective and translucent proprieties in one formula, the dental team can easily achieve a beautiful, natural-looking result."

ZONEfree has the reliable hallmarks of a zinc oxide non eugenol cement in that it is easy to apply, easy to clean up and remove, and provides excellent retention strength. When ZONEfree is dispensed and applied the cement has a pearly white appearance, giving it enough color to allow the dentist or assistant to place it precisely and see excess cement during clean up and removal. Yet, when ZONEfree is spread thin the cement blends with the adjacent surfaces creating a "chameleon effect" that results in a natural esthetic look. As the only translucent zinc oxide non-eugenol temporary cement, dentists can use ZONEfree without worrying about resin on resin build up and other issues common to resin based temporary cements.

"From my perspective, the most important feature of ZONEfree are the reflective nanofillers that get an excellent result with temporaries. That to me is very unique about ZONEfree," said Dr. Gary Radz, D.D.S. of Cosmetic Dentistry of Colorado. "In our office we are focused on patient satisfaction and providing beautiful esthetic dentistry. I can be confident that we achieve both when using ZONEfree." Hear more from Dr. Radz in his video interview.

Other benefits and specifications of ZONEfree temporary cement include:
  • It is Triclosan-free. Triclosan is currently under review by the FDA for safety concerns
  • It has a working time of one and a half minutes; The cement self cures in two minutes with no need for a curing light
  • ZONEfree comes in a 4 gm. automix syringe that provides accurate placement and minimal waste; Includes eight application tips
  • The manufacturer's product number is 27041 and the MSRP is $45

Effectiveness of different carbamide peroxide concentrations used for tooth bleaching: an in vitro study

J. Appl. Oral Sci. vol.20 no.2 Bauru Mar./Apr. 2012 

OBJECTIVES: This in vitro study evaluated the effectiveness of three carbamide peroxide concentrations used for tooth bleaching treatments.
MATERIAL AND METHODS: Sixty bovine dental slabs (6x6x3 mm) were obtained, sequentially polished, submitted to artificial staining (baseline) and randomized into four groups (n=15), according to the bleaching agent concentration: distilled water (control), 10% (CP10), 16% (CP16) or 37% (CP37) carbamide peroxide. CP10 and CP16 were covered with 0.2 mL of the respective bleaching gels, which were applied on enamel surface for 4 h/day during two weeks. Samples of CP37 were covered with 0.2 mL of the bleaching gel for 20 min. The gel was light activated by two 40-s applications spaced by 10-min intervals. The gel was renewed and applied 3 times per clinical session. This cycle was repeated at 3 sessions with 5 days of interval between them. Tooth shade evaluations were done with a digital spectrophotometer at T0 (baseline), T1 (after 1-week of treatment) and T2 (1-week post-bleaching). Tooth shade means were statistically analyzed by Kruskal-Wallis and Friedman's tests and color parameters were analyzed by two-way ANOVA and Tukey's test (p<0.05).
RESULTS: At T1 and T2 evaluations, tooth shade was significantly lighter than at baseline for all treatment groups, considering the color parameters
ΔL*, Δa*, Δb*, ΔE* (p<0.001) or tooth shade means (p<0.001). CP37 group showed lower shade mean change than CP10 and CP16 at T1 (p<0.01), but this difference was not statistically significant at T2 (p>0.05).
CONCLUSIONS: One week after the end of the treatment, all carbamide peroxide concentrations tested produced similar tooth color improveme

Dental implants can cause nerve damage, warns study

Dentists are not being vigilant when carrying out implant surgery and are failing to inform patients about the risks of nerve damage, a study in the British Dental Journal says.
Researchers from King's College London Dental Institute analysed 30 patients with nerve injuries and found problems with pain, speech, eating and kissing.
Around 1% of implant procedures carried out each year result in nerve injuries.

Genetic sensitivity to bitter taste of 6-n Propylthiouracil: A useful diagnostic aid to detect early childhood caries in pre-school children

Indian Journal of Human Genetics
Year : 2012  |  Volume : 18  |  Issue : 1  |  Page : 101-105

Purpose: Genetic factor to bitter taste perception appears to be largely mediated by the TAS2R38 gene. The insensitivity to bitter compounds like 6-n-propylthiouracil (PROP) is mediated by this gene. PROP, a pharmacological drug used in treatment of Graves' disease, proved to be useful tool in determining the genetic sensitivity levels to bitter and sweet taste. The purpose of this study is to show much simpler PROP sensitivity technique for the clinical examiner and its application as a diagnostic aid in Early Childhood Caries (ECC) detection among preschool children.
Materials and Methods: A total of 119 children belonging to the age group of 36 to 71 months of both sexes, were recruited from A. J. Institute of Dental Sciences, Mangalore (Karnataka). PROP sensitivity test was carried out to determine the inherent genetic ability to taste a bitter or sweet substance. This study used simpler scaling method to find out genetic sensitivity to bitter taste; one who tasted bitter as taster and one who was not able to differentiate/tasted like paper as non-taster. A questionnaire was provided to evaluate their dietary habits and caries experience was recorded. Collected data were tabulated and subjected to statistical analysis.
Results: In the total of 119 children the mean dmfs was definitely higher in non-taster children compared to tasters. The tasters had a mean dmfs value of 9.5120 (S.D. 7.0543) and non-tasters had a value of 7.7250 (S.D. 8.33147), which was statistically significant. The results suggested that there was increase in caries experience among the group of non-tasters as compared to tasters. Tasters tended to be sweet dislikers and non-tasters tended to be sweet likers. On the whole, tasters had a bad dentition as compared to non tasters.
Conclusion: The PROP sensitivity test (filter paper test) proved to be a useful diagnostic tool in determining the genetic sensitivity levels of bitter taste. The knowledge of a child's taste perception can help us in identifying the children who are at higher risk for ECC.

ClearCorrect Reveals Integration of Advanced Digital Orthodontic Production Using Objet’s 3D Printing Systems

Houston, TX and Rehovot, Israel, June 12, 2012 – ClearCorrect LLC, a leading manufacturer of clear aligners, today announced collaboration with Objet Ltd., the innovative leader in 3D printing for rapid prototyping and additive manufacturing. ClearCorrect is making Objet’s high resolution, 3D printing systems an integral part of its mass-scale manufacturing of custom-made orthodontic aligners. Together, ClearCorrect and Objet are bringing the advantages of digital 3D printing technology to orthodontics.

The ClearCorrect manufacturing center, located in Houston, Texas, is one of the most advanced digital production centers in the USA. Essential to its operation are a number of recently installed Objet 3D printing systems, making ClearCorrect a major user of the technology in the dental industry. “With the recent implementation of these Objet 3D printing systems, we now have the means to scale rapidly and efficiently in the global market while maintaining the highest quality,” commented ClearCorrect CEO, Jarrett Pumphrey.

The Objet 3D printing systems are a key component of the ClearCorrect process in that they produce the plastic models of each step of the patient’s treatment. ClearCorrect then thermoforms the models to create the clear aligners. Instead of just sending the doctors the clear aligners for the patient, ClearCorrect includes the plastic models along with the clear aligners so that the doctors can use them as needed to fabricate replacement aligners should a patient lose or break an aligner. This way, both the doctor and the patient benefit in costs and saving time as usually a patient would have to wait a couple weeks to receive the replacement aligner.

“Objet and ClearCorrect have worked together to implement Objet's ultra-thin layer, high-resolution 3D printing solutions in the ClearCorrect production process,” said Avi Cohen, Head of Medical Solutions at Objet. "We expect this cooperation will increase overall manufacturing productivity and by bringing together the ClearCorrect system and technology with Objet’s 3D printing systems, we shall achieve top results for the benefit of users worldwide”.

Likeable and Henry Schein Launch Likeable Dentists Platform


    Likeable and Henry Schein Launch Likeable Dentists Platform

    Platform Serves as Full Social Media Solution for Dentists

NEW YORK, June 11, 2012 (GLOBE NEWSWIRE) -- Likeable today announced
the launch of Likeable Dentists, the first vertical of Likeable Local,
a Facebook marketing solution for small businesses. Likeable Dentists
was created in conjunction with Likeable's mission to help
organizations use social media to build relationships, engage with fans
and create a more likeable world.

"We realize that many small business owners don't have the resources to
hire an agency and don't have the time to create content for and grow
their social media pages themselves," said Dave Kerpen, Co-Founder and
CEO of Likeable. "This is the fast, all-encompassing Facebook solution
for small businesses."

Likeable Dentists was launched in partnership with Henry Schein, Inc.

OK to Limit Pre-Dental Procedure Antibiotics to High Risk Heart Patients

Study Highlights:

  --  The incidence of infective may not have increased after the American
      Heart Association changed its recommendations on the use of antibiotics
      before invasive dental procedures.
  --  This study finding from Olmstead County, Minn., supports the guideline
      change, which limited the use of preventive antibiotics to people with
      the highest risks for complications from infective endocarditis.

DALLAS, June 11, 2012 (GLOBE NEWSWIRE) -- The incidence of infective
endocarditis among dental patients in Olmsted County, Minn. did not
increase after new guidelines called for giving preventive antibiotics
before dental procedures only to those at greatest risk of
complications, according to independent research published in
Circulation, an American Heart Association journal.

Infective endocarditis is a bacterial infection of the heart lining,
heart valve or blood vessel. Although rare, it can occur when bacteria
enter the bloodstream through breaks in the gums during invasive dental
procedures or oral surgery. It can cause death if untreated. A common
group of bacteria that cause this infection is viridans group
streptococci (VGS).

Patients with a heart weakened by certain congenital defects and
acquired conditions, including those with prosthetic heart valves, can
be more susceptible to the infection. People with normal heart valves
develop the infection less often.

In 2007, the American Heart Association changed its guidelines,
recommending patients take antibiotics before invasive dental
procedures only if they are at risk of complications from infective
endocarditis. This includes patients with artificial heart valves,
transplanted hearts with abnormal heart valve function, previous
infective endocarditis and people born with specific heart defects.

Before 2007, antibiotics were given to many more people, including
those with many types of congenital heart defect or acquired cardiac
condition. Antibiotics also were given for a wider range of procedures,
including operations involving the mouth, throat, gastrointestinal,
genital or urinary tract.

"We were giving preventive antibiotics like we were treating an entire
iceberg, when we only needed to treat the very tip of that iceberg,"
said Daniel C. DeSimone, M.D., study lead author and an internal
medicine resident at the Mayo Clinic in Rochester, Minn. "Millions of
people once getting antibiotics now are not."

In the first U.S. study examining VGS-related infective endocarditis
rates after the guidelines changed, investigators found a slight
decline in the number of patients diagnosed.

To compare infective endocarditis rates, researchers analyzed local
hospital discharge records in the Rochester Epidemiology Project and
national rates using the Nationwide Inpatient Sample. Olmstead County
was used because of its unique medical records-linkage system that
encompasses all residents of the county.

From Jan. 1, 1999 to Dec. 31, 2010, 22 patients in Olmsted County,
Minn., were diagnosed with the heart infection. These patients
represent two to three of every 100,000 people in the United States
before updated guidelines, and one of every 100,000 after the updated

The percentage of Olmsted county dentists following the new association
guidelines represented the percentage of dentists using them
nationally, researchers said.

The national annual infective endocarditis diagnosis rates showed no
increase, ranging from:

  --  15,300-17,400 in 1999-2006 (before the updated guideline)
  --  14,700-15,500 in 2007-09 (after the updated guideline)

"These findings are reassuring, but additional studies are needed to
further support our findings," DeSimone said.

"There's still a concern among many healthcare providers over whether
we are leaving certain people at risk of getting a potentially lethal
infection just from a dental cleaning or tooth extraction," he said.
"This study should reduce some fears. It will allow dentists to become
more comfortable when they tell a patient, 'You've been getting this
antibiotic for years. Now, it's not recommended anymore, and here is
data showing you why.'"

Among other limitation, the lack of diversity in Olmstead means these

Periodontal disease and the oral microbiota in new-onset rheumatoid arthritis.

Arthritis Rheum. 2012 May 10. doi: 10.1002/art.34539. [Epub ahead of print]


New York University School of Medicine and NYU Hospital for Joint Diseases, New York, New York.


OBJECTIVE.: To profile the subgingival oral microbiota abundance and diversity in never-treated, new-onset rheumatoid arthritis (NORA) patients. METHODS.: Periodontal disease (PD) status, clinical activity and sociodemographic factors were determined in patients with NORA, chronic RA (CRA) and healthy subjects. Massively parallel pyrosequencing was used to compare the composition of subgingival microbiota and establish correlations between presence/abundance of bacteria and disease phenotypes. Anti-P. gingivalis antibodies were tested to assess prior exposure. RESULTS.: The more advanced forms of periodontitis are already present at disease onset in NORA patients. The subgingival microbiota of NORA is distinct from controls. In most cases, however, these differences can be attributed to PD severity and are not inherent to RA. The presence and abundance of P. gingivalis is directly associated with PD severity as well, is not unique to RA, and does not correlate with anti-citrullinated peptide antibody (ACPA) titers. Overall exposure to P. gingivalis is similar in RA and controls, observed in 78.4% and 83.3%, respectively. Anaeroglobus geminatus correlated with ACPA/RF presence. Prevotella and Leptotrichia species are the only characteristic taxa in the NORA group irrespective of PD status. CONCLUSIONS.: NORA patients exhibit a high prevalence of PD at disease onset, despite their young age and paucity of smoking history. The subgingival microbiota of NORA patients is similar to CRA and healthy subjects of comparable PD severity. Although colonization with P. gingivalis correlates with PD severity, overall exposure is similar among groups. The role of A. geminatus and Prevotella/Leptotrichia species in this process merits further study.

Sirona Introduces inLab® Software 4.0

New inLab® Software 4.0 Delivers Improved Power and Performance
 to the Entire Restorative Process

Charlotte, NC (May 23, 2012) Sirona Dental Systems, the company that pioneered digital dentistry more than 27 years ago and the world’s leading producer of dental CAD/CAM systems, has launched a major software upgrade that effortlessly handles everything from single-unit crowns to complete smile makeovers with the touch of a button.

According to Norbert Ulmer, Director of Laboratory CAD/CAM for Sirona, “The new inLab® Software 4.0 is the most significant and sophisticated inLab software release.  It propels the inLab system to new heights with outstanding new features designed for faster and easier navigation through design steps and work direct-on-tooth tools.  This is a major redesign of the inLab software platform.”

Matt Roberts, CDT with CMR Dental Lab, states, “inLab Software 4.0 is a game-changer for digital dentistry.  It’s now even easier to artistically modify the design to fit the specific aesthetic and functional needs associated with each case!”

Among the many enhancements made possible with inLab Software 4.0 are the following:

·         Intuitive Graphical Interface – The inLab software guides you confidently through the design process.  See exactly what step you’re working on, what’s next and what you’ve already accomplished.  Readily “jump” from one design step to the next – or even go back a step or two – without having to “undo” the work you’ve already done.

·         Multiple Restoration Design Work on as many different restorations and indications as you want and at the same time – including in multiple quadrants and opposing arches, from single units to full-mouth cases.

·         Design Tools for Total Control – Design tools can now be executed directly on the tooth when performing functions such as adding or removing material, rotating or positioning the restoration, or expanding or reducing tooth size.  Grab and move the tooth, and use your digital porcelain brush to design your crown.  This provides greater control and a more natural, hands-on feel to the computer design process.

·         Widest Range of Indications Your software capabilities are as endless as this list, such as anatomically shaped copings and bridges, to full-contour crowns, inlays, onlays, veneers, digital temporaries, multilayer/split-file designs, Maryland bridges, customized abutments, model-building software, bars, attachments, stressbreakers, stack milling, digital cutbacks, diagnostic wax-ups, and wax patterns, and there is always another software update just around the corner. 

The increased productivity and efficiency delivered by inLab Software 4.0 is a bottom-line booster, as well.  Chad Rogers has been an inLab user for nearly a decade, and was also among the first to use inLab Software 4.0.  “For me, Sirona has made dental CAD/CAM more predictable and profitable than ever,” he said.  “With the introduction of the new inLab Software 4.0 coupled with the inEos® Blue and the inLab MC XL, my laboratory is quickly changing and becoming a profitable machine.”

Moreover, Sirona Connect takes the digital process even further by providing a reliable conduit between the dental office and laboratory.  Dental professionals utilizing Sirona Digital Impressions acquire an image intraorally and then send the digital impression to the Sirona inLab laboratory in real time.  The time needed for pouring impressions is gone and the lab can design and mill the restoration before the patient has even left the dentist’s office.  The dentist and lab can then discuss the case while the patient is still in the chair, creating better communication and superior results.

Sesame Communications Launches Sesame Sweepstakes™ for Dentistry

SEATTLE, WA — May 1, 2012 — Sesame Communications, the leading provider of online patient communication and engagement tools for the dental industry, today announced the launch of Sesame Sweepstakes, a turnkey contest and sweepstakes service that leverages Facebook™ and other social networks to run online patient promotions for practices.
Sesame Sweepstakes is designed to help practices grow their social media community through word of mouth referrals, extending their reach to their patients’ social media circles to help their practice connect with new prospective patients. A recent study conducted by Sesame found that the average practice increased their Facebook likes by 217% (more than triple) over the course of a single sweepstake promotion. In addition, the same study saw practices average 15 new Facebook patient recommendations from campaign. These trusted referrals work throughout the Facebook community to boost practice visibility and drive new patient appointments.
“Sesame Sweepstakes is a powerful new tool for dental practices to increase patient engagement,” said Diana Friedman, Chief Executive Officer of Sesame Communications. “This service is a significant game changer in how quickly practices can build their online social network through word of mouth referrals, obtain new patients, and engage existing and inactive patients helping to ensure they stay in compliance with their care plans.”
Sesame is currently the only technology company within dentistry to offer comprehensive integration between patient data and contest platforms. Sesame Sweepstakes also features an exclusive Facebook Recommendation Plugin, allowing practices to collect and group their recommendations into one powerful location.
The Sesame platform takes care of all the finite details of the campaign including compliance with Facebook guidelines, local and state regulations, promotional email blasts and newsletters to existing patients, campaign designed landing pages, capturing of entrant contact details, and more.
The practice stays informed on the progress of their campaign every step of the way with detailed reporting on all entrants (including the status on existing, inactive and prospective patient participation), along with daily reporting of all call requests from entrants.

Take Action NOW on Medical Device Tax

From the Academy of General Dentistry (AGD)
The federal government plans to enact a 2.3 percent medical device tax beginning January 1, 2013, unless you take action today.
This proposed tax, which was one of the key lobbying issues at the Academy of General Dentistry’s (AGD) 2012 Government Relations Conference, will impose a fee on any medical treatment or device on the manufacturers, importers, and producers of taxable medical devices. Dental devices, such as crowns, dentures, intra-oral appliances, bridges, etc., are included in the definition of medical devices.
The AGD, and numerous other healthcare associations, believes that the tax should be repealed, or at the very least that dental treatments and devices should be exempt from this ruling since they are customized specifically, uniquely, precisely or surgically for a specific patient.
This excise tax, while originally projected to raise $20 billion in revenue, is now estimated to collect more than $30 billion in taxes. But at what cost? It will increase patients’ out-of-pocket expenses for dental care, cause some patients to delay care, and will stifle product innovation. You, as a health care provider, will need to determine whether to shift this increased expense to your patients or to absorb the tax as another cost of doing business. Neither answer is the right one.
The only right answer is to contact your legislators today and urge them to repeal this tax now. Please contact your federal legislators today and ask that they repeal the medical device excise tax.

Amalgam or composite resin? Factors influencing the choice of restorative material

Available online 28 April 2012


This study aimed to investigate the patient and tooth factors associated with selection of restorative material in direct posterior restorations in young adults from a population-based birth cohort.


A representative sample (n = 720) of all 5914 births occurring in Pelotas in 1982 were prospectively investigated, and posterior restorations were assessed in 2006, when the patients were 24 years old. Tooth-related variables (individual level) included restorative material (amalgam or composite), type of tooth, size of cavity, and estimated time in mouth. Data regarding demographic and socio-economic characteristics, oral health, and service utilization patterns during the life course were also assessed (contextual level).


Logistic Regression Multilevel models showed that individuals who have accessed dental services by private insurance by age 15 [odds ratio (OR) = 1.66 (0.93–2.95)] and who had a higher dental caries index at age 15 (high DMFT tertile) [OR 2.89 (1.59–5.27)] presented more amalgam restorations in the posterior teeth. From tooth-level variables, the frequency of amalgams decreases with increasing number of surfaces enrolled in the cavity preparation (p < 0.001) and was almost 5 times greater in molars than in premolars.


The present findings suggest that variables related to type of dental service, dental caries (higher DMFT index), and cavity characteristics (tooth type, size) determine the choice of dentists for restorative materials. Other individual characteristics such as demographic and socioeconomic status have not influenced this choice.

Clinical significance

This is the first population-based study that assesses the determinant factors for the choice of dentists for composite or amalgam in posterior direct restorations, showing that, independently of socioeconomic and demographic characteristics, type of payment of dental services and clinical factors are associated with this choice.

Reconditioning of ceramic orthodontic brackets with an Er,Cr:YSGG laser

2012, DOI: 10.1007/s10103-012-1093-4


It is now known that erbium lasers are effective in composite removal, but there is minimal information about their efficacy on recycling of ceramic brackets. This study, therefore, aimed to determine the percentage of remaining adhesive on the base and the shear bond strength of debonded ceramic brackets after being reconditioned by an Er,Cr:YSGG (erbium, chromium: yttrium–scandium–gallium–garnet) laser. Thirty premolars were divided into three groups, then bonded with mechanical retention ceramic brackets according to the bracket base conditions: (1) new brackets; (2) debonded brackets cleaned of adhesive with the Er,Cr:YSGG laser at 3.5 W; and (3) debonded brackets cleaned of adhesive with the Er,Cr:YSGG laser at 4 W. Before bonding, the percentage of remaining adhesive on the bases of reconditioned brackets was calculated by using stereomicroscopic images through an image processing software. The brackets were then tested in shear mode in a universal testing machine and the adhesive remnant index scores were determined. The percentage of remaining adhesive on the bases of brackets that were cleaned by the Er,Cr:YSGG laser at 4 W (3.1 %) was significantly lower than that of the 3.5-W laser group (5.9 %) (p = 0.03). No significant difference was found in bond strengths between the new and the reconditioned brackets (p  = 0.19). The frequency of bond failure at the enamel-adhesive interface was lower in the laser-reconditioned brackets when compared to the new brackets. The application of Er,Cr:YSGG laser was efficient in removing adhesive from bases of debonded ceramic brackets because it produced comparable bond strengths to new brackets while reducing the risk of enamel damage during debonding.

Effect of air polishing with glycine powder on titanium abutment surfaces

Clinical Oral Implants Research
Article first published online: 25 MAY 2012
DOI: 10.1111/j.1600-0501.2012.02490.x



The aim of the present study was to evaluate morphological changes induced by glycine powder air polishing on titanium surfaces and its effect on bacteria recolonization in comparison with sodium bicarbonate powder.

Materials and methods

5 mm wide and 1 mm thick titanium grade II disks were divided into three groups of treatments: (i) no treatment; (ii) air polishing with glycine powder; (iii) air polishing with sodium bicarbonate powder. Specimens were characterized by laser profilometry, scanning electron microscopy (SEM) and then installed onto removable appliances worn for 24 h by healthy volunteers. Surface contamination was evaluated using SEM and counting the number of colony forming units (CFU).


SEM observation revealed an increased roughness with the formation of craters on samples treated with sodium bicarbonate powder, while not in glycine ones. Statistical analysis failed to show significant differences of both Ra and Rmax parameters in treated groups. SEM observation of specimens surfaces, after 24 h of permanence in the oral cavity, showed a higher contamination of the disks treated with sodium bicarbonate compared with those not treated (P < 0.05). Conversely, the group treated with glycine showed the lower contamination if compared with bicarbonate-treated group (P < 0.05).


Air polishing with glycine powder may be considered as a better method to remove plaque from dental implant because glycine is less aggressive than sodium bicarbonate powder. Moreover, the use of glycine powder seems to have an active role on the inhibition of bacterial recolonization of implants in a short test period (24 h). Further studies are needed to demonstrate the bacteriostatic properties of glycine, envisaged on the basis of reduced contamination of the disks polished with glycine compared with those not treated.
