CAO Group to Host “Beauty Week” at 2010 Greater New York Dental Meeting

West Jordan, UT (November 29, 2010) – In celebration of its revolutionary patient-friendly Sheer Film delivery system, the CAO Group, Inc. (CAO), a worldwide provider of innovative dental devices and materials, will present “Beauty Week” at the 2010 Greater New York (GNY) Dental Meeting from November 28th through December 1st. 

As part of Beauty Week, all GNY attendees who visit CAO booth #5237 will receive a free Sheer White!teeth whitening film application.  They will be encouraged to apply the film on the spot in order to experience the many benefits that the new Sheer Film delivery system provides, including easy and secure application, and fast whitening results.

Each participant will have the opportunity to capture their Sheer White! experience with a “framed” electronic picture taken at the booth, and a short video segment will capture the individual with the Sheer White! film in place in order to demonstrate how Sheer White! Is virtually undetectable when talking or in use.  

Each participant’s picture will be sent to the individual electronically, and will include a link to a special photo montage video posted on YouTube® showcasing all GNY participants who tried the Sheer White! films.  The first person identified by 10 friends in the YouTube comments section of the site will win a free Patient Kit of Sheer White! teeth whitening film for all 10 people who mention them by name!

“We are excited to have as many people possible experience our Sheer White! teeth whitening films,” remarked Robert Nordquist, Vice President of Marketing and Sales for the CAO Group. 
“Although CAO’s Beauty Week will be focused primarily on its Sheer White! teeth whitening films, all Sheer Film products, including Sheer DesenZ Desensitizing Treatment and Sheer FluorX Fluoride Treatment, will be available for trial.”

About Sheer White! Teeth Whitening Films

Consisting of thin, flexible films plus 20% carbamide peroxide gel, new Sheer White! teeth whitening films employ the most advanced delivery system available today.  Using CAO’s innovative and proprietary thin, flexible Sheer Film material, Sheer White! teeth whitening films are easily molded to individual tooth and arch anatomy and cover from approximately first molar to first molar.  The Sheer Film material molds tightly to the teeth, ensuring complete contact of Sheer White!’s whitening gel to enamel and effectively preventing washout or leakage down the patient’s throat.

Moreover, Sheer White! teeth whitening films are very comfortable and discreet.  Unlike whitening trays or old-style “strips,” patients are able to speak clearly, so Sheer White! teeth whitening films can be worn anytime – at work or even overnight.

Sheer White! is the new and better alternative to traditional whitening products such as tray delivery or strip products.  Sheer White! is also the perfect complement to in-office whitening,  as patients usually must finish treatment at home.  With Sheer White!, there is no tray to fabricate, no lab costs, and whitening can begin immediately.

Radiation Worries for Children in Dentists’ Chairs

A scathing article on CBVT and dental radiography in general. 

Read the article in the NY Times.

A statement reiterating the ADA's guidance on the use of CBCT and other radiological devices can be found here.
If member dentists should ask about this story - or want to know how they should talk about this issue with patients -- we've prepared some talking points that you should feel free to pass along, at this link.

ADA positions hold that dentists should apply the ALARA principle (As Low as Reasonably Achievable) to reduce radiation exposure to their patients by: determining the need for and type of radiographs to take; using "best practices" during imaging, including the application of quality control procedures; and, interpreting the images completely and accurately.
"Dentists should weigh the benefits of dental radiographs against the consequences of increasing a patient's exposure to radiation, the effects of which accumulate from multiple sources over time," according to the ADA's Council on Scientific Affairs report, "The Use of Dental Radiographs: Update and recommendations.

Never Mind Conflict With The In-Laws; It's Cake Vs. Cranberry, Pie Vs. Wine At Thanksgiving Dinner

Never Mind Conflict With The In-Laws; It's Cake Vs. Cranberry, Pie Vs. Wine At Thanksgiving Dinner 

If you're lucky, it will all be kisses and hugs around the Thanksgiving dinner table, with friends and family near and dear gathered about, and puppies at your feet waiting for table scraps.

But peace won't reign within the confines of the oral cavity, where Streptococcus mutans and other harmful bacteria will await their own holiday feast. Your meal will enable S. mutans to launch one of its biggest assaults of the year on your tooth enamel.

New work by dental researchers at the University of Rochester Medical Center brings both good and bad news. While bacterial forces in your mouth will exploit your delectables in newly discovered ways, some foods common at the holiday dinner table - like the cranberry and even wine - offer new leads in the effort to stop tooth decay.

The Thanksgiving Day battle for oral health hinges on microbes like S. mutans. Most cookies, pies and the like contain mountains of sugar, but it's not the sugar itself that causes tooth decay. Rather, S. mutans and other bacteria in our mouths - billions of individual microbes all waiting for their next snack - feast on the sugars, stick on your teeth and then churn out acid that eats away at tooth enamel.

At the front lines is Hyun "Michel" Koo, D.D.S, Ph.D., a dentist turned food scientist and microbiologist who is both exploring the destructive power of S. mutans and scouring foods and natural substances to harness their ability to prevent cavities. With every portion of bad news he delivers about cavities comes good news about compounds that may help prevent tooth decay.

"Natural substances offer tremendous possibilities for stopping tooth decay," said Koo, who earlier this year received a $1.6 million from the National Institute of Dental and Craniofacial Research to conduct his research. "Our time spent in the laboratory is aimed at harnessing the potential of some of these compounds, perhaps eventually incorporating them into a toothpaste or mouth rinse to stop dental decay."

Good news at the dinner table

Koo is hot on the trail of the cranberry as a potential ally in the fight against S. mutans, which is a threat to our teeth primarily because of its ability to form plaque. What appears to us as sticky white gunk along our teeth is actually a formidable fortress of molecules known as glucans - building blocks of plaque, stacked like bricks in a wall, rife with bacteria. It's a gunky fortress that covers the tooth and gives bacteria a safe haven to munch on sugar, thrive, and churn out acid.

Koo has discovered that compounds within the cranberry disrupt enzymes known as glucosyltransferases that bacteria use to build glucans. Without its glucans, S. mutans and other bad bacteria in plaque becomes vulnerable.

Together with Nicholi Vorsa, Ph.D., director of the Philip E. Marucci Center for Blueberry and Cranberry Research and Extension at Rutgers University, Koo is working to isolate the compounds within the cranberry that are most protective. The pair has identified molecules known as A-type proanthocyanidins as having potential to reduce cavities dramatically. Earlier this year in the journal Caries Research, the team reported that when the molecules were applied, glucan and acid production by S. mutans was reduced by up to 70 percent, and cavity formation in rats was slashed by up to 45 percent.

"Maintaining the natural balance of resident flora in the oral cavity is important for keeping opportunistic pathogens in check," said Koo, a researcher in the Center for Oral Biology and an associate professor in the Eastman Institute for Oral Health and the Department of Microbiology and Immunology. "These molecules don't outright kill S. mutans. Instead, they disrupt the two most harmful actions of this pathogenic organism, acid production and glucan production."

More good news

More good news comes from that delicious glass of wine, or at least the waste in its wake. With funding from the U.S. Department of Agriculture, Koo began a research project with Olga I. Padilla-Zakour, Ph.D., associate professor of Food Processing at the New York Agricultural Experiment Station of Cornell University. They found that the abundant waste from the red-wine-making process - materials such as fermented seeds and skins collectively known as pomace that are cast away after grapes are pressed - contains compounds that fight S. mutans. In particular, some polyphenols can inhibit the activity of S. mutans' crucial enzymes by as much as 85 percent and also reduce the amount of acid the bacteria produce.

And the bad news

Last month in PloS One, Koo showed that S. mutans is even more powerful than scientists have realized, responding readily to changing environmental conditions in the presence of starch and sucrose to thrive in the mouth.

In work led by Marlise Klein, D.D.S., Ph.D., research assistant professor, Koo's team analyzed the activity of more than 300 genes in S. mutans under changing conditions. The team found that certain key proteins boost their activity dramatically in the presence not only of sugar but also complex carbohydrates derived from starch digestion. Once the body's own amylase enzymes naturally present in saliva break down starches, S. mutans kicks its glucan-forming machinery into high gear.

"The new research shows how two pillars of the modern diet, starch and sugar, can work cooperatively to bring about tooth decay," said Koo. "A cookie, sugar-covered doughnut, or a piece of pie filled with both sugar and starch provide the perfect recipe for the bacteria that destroy teeth."

Even when the amount of sugar was slashed in half, certain genes central to the ability of S. mutans to create its formidable glucan fortress boosted their activity five-fold in the presence of starch-derived carbohydrates. That enabled the bacteria to create plaque that is hardier, stickier, and capable of producing more acid than plaque created without significant starch present.

On Thanksgiving Day ......

Koo notes people shouldn't simply eat more cranberry sauce or drink more wine to try to prevent cavities. His work is aimed at identifying and then exploiting specific compounds that give the benefit without, for instance, the high levels of acidity or the added sugar that cranberry products might include. Rather, at this point, everything your dentist keeps telling you remains the best advice to prevent cavities.

"On Thanksgiving Day, like any day, brush your teeth, avoid foods filled with sugars as best you can, and don't snack often - and if you do, brush your teeth again," said Koo. "Consider using a mouth rinse, get some fluoride in there - and be sure to see a dentist regularly."

Effects of casein phosphopeptide amorphous calcium fluoride phosphate paste on white spot lesions and dental plaque after orthodontic treatment: a 3-month follow-up

European Journal of Oral Sciences

Volume 118, Issue 6, pages 610–617, December 2010
  1. M. W. Beerens,
  2. M. H. Van Der Veen,
  3. H. Van Beek,
  4. J. M. Ten Cate
 The effects of casein phosphopeptide amorphous calcium fluoride phosphate (CPP-ACFP) paste vs. control paste on the remineralization of white spot caries lesions and on plaque composition were tested in a double-blind prospective randomized clinical trial. Fifty-four orthodontic patients, with multiple white spot lesions observed upon the removal of fixed appliances, were followed up for 3 months. Subjects were included and randomly assigned to either CPP-ACFP paste or control paste, for use supplementary to their normal oral hygiene. Caries regression was assessed on quantitative light-induced fluorescence (QLF) images captured directly after debonding and 6 and 12 wk thereafter. The total counts and proportions of aciduric bacteria, Streptococcus mutans, and Lactobacillus spp. were measured in plaque samples obtained just before debonding, and 6 and 12 wk afterwards. A significant decrease in fluorescence loss was found with respect to baseline for both groups and no difference was found between groups. The size of the lesion area did not change significantly over time or between the groups. The percentages of aciduric bacteria and of S. mutans decreased from 47.4 to 38.1% and from 9.6 to 6.6%, respectively. No differences were found between groups. We observed no clinical advantage for use of the CPP-ACFP paste supplementary to normal oral hygiene over the time span of 12 wk.

Curve Dental Developing Patient Check-in and Questionnaire App for the iPad

Downloadable app allows Curve Dental customers to create forms their patients can complete using an iPad

OREM, UT—Curve Dental, creators of Web-based dental software, announced their development of an iPad app that will modernize the way in which patient information is gathered and digitized in the dental practice. Using the new app, called Curve Questionnaire, the dental practice can create check-in, medical history and other types of forms for their patients to complete using an iPad. Data entered by the patient is written directly to Curve Dental’s Web-based dental software when the patient submits the questionnaire.
“We recognize that the iPad can change the way information is gathered in the dental practice,” said Matt Dorey, founder and managing director of Curve Dental. “The iPad represents an enhancement to a practice’s professional appearance. How much more innovative and capable will a practice appear to the patient when they are handed an iPad to complete a medical history questionnaire rather than a clipboard and a stack of papers? And how much more efficient is the process of gathering and digitizing this information when it’s collected using an iPad? Once the patient has completed the questionnaire their information is immediately written to the practice’s patient data. The Curve Questionnaire saves a great deal of time since the dental team doesn’t have to re-enter the patient’s information like they would with paper forms.”
Using the app, the dental practice can create any number of different forms or questionnaires depending upon their needs. The practice can determine what questions to ask and how each question can be answered, whether with a yes or no response, multiple choice, or open-ended. The Curve Questionnaire app will be available to all Curve Dental customers without charge. The app will also complement Curve Dental’s Web-based dental software.
 “Curve Questionnaire is our first app developed specifically for the iPad,” said Dorey. “It benefits the practice in a number of different ways, from reducing paper costs to the time required to manage paperwork. Just as we leverage the many advantages of the Web and the cloud as a platform for our software, we will continue to leverage the unique capabilities the iPad delivers to the dental practice by developing new apps that will benefit our customers. More and more doctors are looking to the Web as a way to simplify the dental software experience. Doctors are tired of installation hassles, upgrade worries, hardware compatibility issues, and backup concerns generally attributable to client-server software. The Web experience, on the other hand, is much more simple.”
About Curve Dental, Inc.
Founded in 2005, Curve Dental provides web-based dental software and related services to dental practices within the United States and Canada. The company is privately-held, headquartered in Orem, Utah with offices in Calgary, Canada and Dunedin, New Zealand. The company strives to make dental software less about computers and more about the user experience. Their creative thinking can be seen in the design of their software, that’s easy to use and Web-based. Dentists can call 888-910-4376 or visit for more information.

Practical Strategy For Oral Cancer Management In Dental Practices Published, UK

14 Nov 2010
The British Dental Association (BDA) has published a practical guide to help dental professionals combat the growing problem of oral cancer. It reiterates the importance of the early detection of the condition, stressing the improved chances of patient survival in cases where early diagnosis takes place. The proportion of patients with oral cancer who die is higher than for cervical, breast or prostate cancers, the guide points out. It also warns that some patients are beginning to take legal action against dentists alleging failure to detect the condition.

The BDA guide, Early detection and prevention of oral cancer: a management strategy for dental practice, offers practical advice on preventing, detecting and managing oral cancer. It addresses both the clinical aspects of the condition and the management of relationships with patients. It explains the risk factors for the disease, provides guidance on talking to patients about examinations and offers tips on medical history taking and record keeping. It also explores taboos around the practitioner's right to explore patients' lifestyle choices that can cause oral cancer, such as drinking, smoking and chewing tobacco, and offers advice on how to overcome them.

Professor Damien Walmsley, the BDA's Scientific Adviser, said:

"The magnitude of the problem of oral cancer in the UK is growing. While the treatment of many cancers is leading to an improvement in survival rates, the same cannot be said for oral cancer. Early detection is absolutely vital to addressing this situation.

"General dental practitioners and their teams are ideally placed to lead the fightback, but they face many practical difficulties including patient resistance to practitioners' advice on lifestyle factors. This publication provides in-depth guidance on overcoming those problems and involving the whole dental team in the effective prevention, detection and treatment of the disease."

BDA members can access the guide free of charge here.


1. Early detection and prevention of oral cancer: a management strategy for dental practice was edited by Professors Paul Speight (University of Sheffield), Saman Warnakulasuriya (King's College London and World Health Organisation Collaborating Centre for Oral Cancer, UK) and Graham Ogden (University of Dundee).

2. It is published during Mouth Cancer Action Month (MCAM) 2010, which takes place in November. The month is organised by the British Dental Health Foundation (BDHF) and is supported by a group of organisations including the BDA. Details of MCAM 2010 are available here.

Charitable Gifts And Dental Novelties On The BDA Christmas Shopping List, UK

Charitable Gifts And Dental Novelties On The BDA Christmas Shopping List, UK

11 Nov 2010  

The British Dental Association (BDA) has unveiled a collection of Christmas gifts that will appeal to the dental community. It features both a range of charity gifts in association with Dentaid, the UK-based oral health charity dedicated to improving oral health around the world, and dental-themed gifts which offer novel varieties of everyday items.

A variety of gift packages to fund dental care in the developing world are available. Created by Dentaid, packages range in cost from £15, which would help produce and distribute oral health education kits, to £500 which would provide medical and dental care for a whole year for an orphanage in Cambodia. Donors will receive a gift card informing the recipient how their 'gift' has been put to use. This campaign provides practitioners with an alternative way to contribute to the promotion of good oral health in keeping with the spirit of the season. One hundred per cent of the revenue from this campaign goes to Dentaid.

Amongst the range of gift items are a collection of dentistry-themed cartoon prints in high-quality, hand-made frames which can be ordered either individually or as a set of four. Golf fanatics will appreciate the tooth-shaped 'cavi-tees' and ball markers, while those refurbishing the practice might find the tooth floor lamp adds a fun and funky finishing touch. Meanwhile, the matching tooth and brush cufflinks are an understated but witty accessory for the sartorially inclined.

Orders can be placed now here. BDA members benefit from discounted prices and enjoy free delivery on the gift items only. Orders for pre-Christmas delivery must be placed before 17 December.

Oral Health Literacy among Female Caregivers: Impact on Oral Health Outcomes in Early Childhood.

J Dent Res. 2010 Oct 5. [Epub ahead of print]
Department of Pediatric Dentistry, School of Dentistry, University of North Carolina at Chapel Hill.


The aim of this study was to investigate the association of female caregivers' oral health literacy with their knowledge, behaviors, and the reported oral health status of their young children. Data on caregivers' literacy, knowledge, behaviors, and children's oral health status were used from structured interviews with 1158 caregiver/child dyads from a low-income population. Literacy was measured with REALD-30. Caregivers' and children's median ages were 25 yrs (range = 17-65) and 15 mos (range = 1-59), respectively. The mean literacy score was 15.8 (SD = 5.3; range = 1-30). Adjusted for age, education, and number of children, low literacy scores (< 13 REALD-30) were associated with decreased knowledge (OR = 1.86; 95% CI = 1.41, 2.45) and poorer reported oral health status (OR = 1.44; 95% CI = 1.02, 2.05). Lower caregiver literacy was associated with deleterious oral health behaviors, including nighttime bottle use and no daily brushing/cleaning. Caregiver oral health literacy has a multidimensional impact on reported oral health outcomes in infants and young children.

Growth factor regenerates tooth supporting structures: Results of a large randomized clinical trial

Alexandria, Va., USA – It is well known that oral infection progressively destroys periodontal tissues and is the leading cause of tooth loss in adults. A major goal of periodontal treatment is regeneration of the tissues lost to periodontitis. Unfortunately, most current therapies cannot predictably promote repair of tooth-supporting defects. A variety of regenerative approaches have been used clinically using bone grafts and guiding tissue membranes with limited success.
In an article titled "FGF-2 Stimulates Periodontal Regeneration: Results of a Multicenter Randomized Clinical Trial," which is published in the International and American Associations for Dental Research's Journal of Dental Research, M. Kitamura, from Osaka University Graduate School of Dentistry, Japan, and a team of researchers conducted a human clinical trial to determine the safety and effectiveness of fibroblast growth factor-2 (FGF-2) for clinical application. This is the largest study to date in the field of periodontal regenerative therapy.
A randomized, double-masked, placebo-controlled clinical trial was conducted in 253 adults afflicted with periodontitis. Periodontal surgery was performed, during which one of three different doses of FGF-2 was randomly administered to localized bone defects. Each dose of FGF-2 showed significant superiority over the standard of care (vehicle alone (p < 0.01)) for the percentage of bone fill at 36 wks after administration, and the percentage peaked in the mid-dose FGF-2 group. These results strongly support the topical application of FGF-2 can be efficacious in the regeneration of human periodontal tissue that has been destroyed by periodontitis.
"This study represents the largest multi-center human clinical trial using growth factor therapy to repair tooth-supporting osseous defects," said JDR Editor-in-Chief William Giannobile. "The tissue engineering technology has important ramifications in the treating of localized bone defects around teeth resulting from periodontal disease."
The abstract is published in the Journal of Dental Research and is available online at

American Dental Association Statement: Kellogg Study Of Alaska Dental Health Aide Therapist Program

We always welcome an organization of the stature of the WK Kellogg Foundation to join us in our mission to improve the oral health of the nation's most vulnerable populations. However, the ADA believes that prevention, oral health literacy, and rebuilding our public health infrastructure should guide concerned stakeholders as we seek a permanent solution to the access to care crisis in this country.

Alaska is unique among the states in the degree to which geography presents a profound barrier to care. It is not representative of the remaining 49 states in this great nation. In many rural states for instance, residents are accustomed to driving hours to reach a shopping or entertainment destination and can be expected to travel similar distances to reach a dentist.

The published report on the study of the dental health aide therapist (DHAT) model was based on a very small number of participants in Alaska-it examined five therapists and 300 residents-and does not constitute the kind of empirical health outcomes data on which to base major health policy decisions. Even the report's principal investigator concedes that the evaluation did not assess the overall impact that treatment by dental therapists could have on improving the oral health of Alaska natives.

The ADA believes that workforce innovations such as our own community dental health coordinator (CDHC) show greater potential in helping underserved people overcome the profound barriers that limit or completely block their access to dentists. The CDHC is based on a proven model-the community health worker-which has been extraordinarily successful in educating patients in their various communities to seek medical care. We feel that a similar model could be equally effective in promoting dental care.

The degree and severity of disease among underserved communities, whether they are in inner cities, remote rural communities, or on Tribal lands, demands sustainable solutions. The ADA feels that any investment of our limited resources should be directed to improving the ability of our current workforce to address this problem. The nation needs a concerted effort by all who are concerned about the oral health of the underserved to help the dental profession locate dental homes for our entire population. This will require adequate funding for safety net programs, implementing loan reduction/forgiveness programs for new graduates from dental schools, boosting our efforts to educate our patients to properly maintain their oral health with effective hygiene, providing urgent care by dentists for patients with immediate needs, and the inclusion of all of our initiatives to prevent and control the epidemic of untreated disease.

People living with diabetes are twice as likely to develop serious gum disease

NEW YORK, NY (November 1, 2010) – For the nearly 24 million Americans living with diabetes, many may be surprised to learn about an additional complication associated with the condition – serious gum disease. According to the Center for Disease Control (CDC), there is an increased prevalence of gum disease among those with diabetes, making proper oral health and hygiene a key factor to living well with diabetes[i].

Recent research shows that people living with diabetes are twice as likely to develop serious gum disease as people without diabetes[ii]. They are at an increased risk for gum disease because they are generally more susceptible to bacterial infection, and have a decreased ability to fight bacteria that invade the gums. Emerging research also suggests that the association between serious gum disease and diabetes is a two-way relationship. Not only are people with diabetes more susceptible to developing gum disease, but serious gum disease also known as periodontitis can adversely affect blood glucose control and contribute to the progression of diabetes[iii].

“Overall, there is low awareness among the diabetes community about the association between oral health and the short and long-term implications it may have on a successful, comprehensive diabetes management plan,” said Dr. Maria Emanuel Ryan, a professor of oral biology and pathology at Stony Brook University in Stony Brook, N.Y. “One of the many complications of diabetes is a greater risk for periodontal disease. Poor control of diabetes can cause various adverse effects in the mouth, such as salivary gland dysfunction, dental caries and oral infections.  If you have oral infection and inflammation, it’s much more difficult to control blood glucose levels. Intensive periodontitis treatment significantly reduces levels of A1C, a measure of glucose control over the prior two to three months.”

Aligned with Diabetes Awareness Month, primary care providers and dental professionals across the country are educating their patients about the association between oral health and diabetes and on the importance of good oral health as a part of overall diabetes management.

Diabetes patients can combat the risk of gum disease and other oral health problems by flossing, visiting the dentist regularly and brushing daily with antibacterial toothpaste like Colgate Total®. Unlike ordinary toothpaste, Colgate Total® toothpaste reduces germs that cause gingivitis, an early form of gum disease, by 90% vs. regular fluoride toothpaste 12 hours after brushing. In addition, it is the only toothpaste approved* by the FDA to help prevent gingivitis and the #1 recommended most by dentists for gum care.

In recognition of Diabetes Awareness Month, Colgate Total® toothpaste offers the following tips for building good oral hygiene habits:

    Control your glucose levels: If your blood glucose levels are poorly controlled, you are more likely to develop serious gum disease than people without diabetes
    Floss at least once a day: Flossing helps remove plaque between your teeth and under your gum line
    Brush at least twice a day and use an antibacterial toothpaste: This is proven to reduce the germs that can lead to gum disease
    Schedule regular dental cleanings: Visit your dentist at least twice a year for professional cleanings and remind your dentist that you have diabetes – oral care should be a part of your overall diabetes management care to ensure that serious gum disease isn’t causing your blood sugar to rise, making diabetes harder to control
    Look for early signs of gum disease: Report any signs of gum disease — including redness, swelling and bleeding gums — to your dentist

Colgate Total® toothpaste is committed to promoting proper oral health practices for healthy living.  For more information about the link between oral health and diabetes, please visit

About Periodontal Disease
Untreated gingivitis can progress to periodontitis, which is a serious infection that destroys the soft tissue and bone that support your teeth. This can eventually cause tooth loss.   People living with diabetes are prone to many infections, including gum infections. In addition, gingivitis and periodontitis impair your body's ability to utilize insulin, making diabetes harder to control. Proper oral health is an easy solution to preventing gum disease and helping to maintain better blood sugar management. Preventative oral health care measures include regular dental visits, flossing and brushing your teeth with Colgate Total® toothpaste.

About Colgate Total® Toothpaste
Colgate Total® toothpaste has an antibacterial formula clinically proven to actively fight germs for 12 hours. It is the only toothpaste both approved* by the U.S. Food and Drug Administration (FDA) and accepted by the American Dental Association to fight plaque and gingivitis.  Colgate Total® toothpaste is also the number one toothpaste recommended most by dentists and hygienists. It has not been approved for the prevention or treatment of serious gum disease or other diseases. For more information about Colgate Total® toothpaste, visit

Factors influencing marginal cavity adaptation of nanofiller containing resin composite restorations

Dental Materials
Volume 26, Issue 12, Pages 1166-1175 (December 2010)
Hidekazu Takahashia, Werner J. Fingerb, Kerstin Wegnerc, Andreas Utterodtd, Masashi Komatsub, Bernd Wöstmannc, Markus Balkenhole


The aim of this study was to investigate the effects of polymerization contraction, shrinkage stress and Young's modulus of nanofiller containing resin composites on early marginal adaptation of restorations in cavities.
Six nanofiller containing and two reference resin composites were studied. Marginal gap widths of restorations in cylindrical 4.2mm wide and 1.5mm deep dentin cavities, non-bonded or bonded with a self-etch adhesive, and in Teflon cavities of same dimensions were determined 15min after irradiation (n=8). Polymerization shrinkage strains were measured using the bonded-disk (n=8) and a strain gage method (n=8). For determination of contraction stress the composites (n=10) were bonded to and cured in Araldit molds using a photoelastic method. Flexural moduli of the restoratives were studied according to ISO specification 4049 (n=5). Statistical analysis was performed with one- and two-way ANOVA, Kruskal–Wallis ANOVA test and post hoc tests (p<0.05).
Only two nanofiller composites (Kalore, GC, Japan) and Venus Diamond (Heraeus Kulzer, Germany) showed consistently gap-free margins in bonded dentin cavities. The mean gap widths in non-bonded and in Teflon cavities were 6.1–12.8 and 14.1–25.5μm, and linearly correlated (r2<0.85). Significant linear relationships were observed between strain, stress and marginal gap widths in non-bonded and Teflon cavities (p<0.01). Flexural moduli (15min) were between 1.66 and 8.63GPa.
Marginal cavity adaptation of restorations in bonded dentin cavities reflects complex interactions between adhesive bonding on the one hand, and polymerization contraction strain, stress and elastic modulus, on the other.

Substantial Consumption Of Fluoride Increases Chance Of Mild Fluorosis Researchers Continue To Recommend Benefits Of Fluoride To Prevent Tooth Decay

Young children who consume substantial amounts of fluoride through infant formula and other beverages mixed with fluoridated water or by swallowing fluoride toothpaste have an increased chance of developing mild enamel fluorosis, according to research published in the October issue of The Journal of the American Dental Association and supported by the National Institute of Dental and Craniofacial Research. Children can continue using fluoridated water and fluoride toothpaste because fluoride has been proven to prevent tooth decay, and mild fluorosis does not negatively affect dental health or quality of life.

"Nearly all of the fluorosis in our study participants was mild. A recent review of the effects of mild dental fluorosis on oral health related quality of life concluded that the effect of mild fluorosis was not adverse and could even be favorable," according to the study. "This suggests that concerns about mild dental fluorosis may be exaggerated. Therefore, no general recommendations to avoid use of fluoridated water in reconstituting infant formula are warranted. "

According to the American Dental Association, mild enamel fluorosis appears as barely noticeable faint white lines or streaks on tooth enamel that may occur when children ingest excess fluoride while their teeth are developing.

Researchers concluded that substantial fluoride consumption from beverages with fluoridated water, including infant formula, by children between the ages of 3 to 9 months, elevates a child's prospect of developing mild enamel fluorosis. Substantial fluoride consumption from beverages with fluoridated water and from fluoride toothpaste by children between the ages of 16 to 36 months also elevates a child's probability of developing mild enamel fluorosis.

The American Academy of Pediatrics recommends breastfeeding for infants. If parents are concerned about reducing the chances of their infants developing mild fluorosis through consuming substantial amounts of infant formula mixed with fluoridated water, the researchers suggest that they consult with their family dentist or physician. The researchers also encourage parents to follow recommendations to use small (smear or pea-sized) amounts of fluoridated toothpaste and ensure proper supervision of the child's tooth brushing.

Researchers recruited mothers of newborn infants from eight Iowa hospital postpartum wards between 1992 and 1995 for their children's participation in what would become known as the Iowa Fluoride Study, an investigation of dietary and non-dietary fluoride exposures, dental fluorosis and dental cavities. Researchers sent questionnaires to the parents at regular intervals and 630 children underwent visual dental examinations using standardized techniques and portable equipment. The leader of the research team was Steven M. Levy, D.D.S., M.P.H., the Wright-Bush-Shreves Endowed Professor of Research in the Department of Preventive and Community Dentistry at the University of Iowa's College of Dentistry and Professor of Epidemiology at the College of Public Health.

Efficacy and safety of an intraoral electrostimulation device for xerostomia relief: A multicenter randomized trial.

Arthritis Rheum. 2010 Sep 29. [Epub ahead of print]
CharitéCentre 3 for Dental, Oral and Maxillary Medicine, Department of Oral Medicine, Dental Radiology and Oral Surgery, Charité Universitätsmedizin Berlin (Berlin, Germany).


OBJECTIVE: The objective of the study was to evaluate the efficacy in treating xerostomia and the safety of an intraoral electrostimulation device, containing stimulating electrodes, an electronic circuit and a power source. The device delivers electrostimulation through the oral mucosa to the lingual nerve, in order to enhance the salivary reflex.
METHODS: The device was tested on a sample of patients with xerostomia due to Sjögren's syndrome and other sicca conditions in a prospective randomized multi-center trial consisting of two stages: (I) a double blind, cross-over designed stage to compare the effects of the electrically "active" device with the "sham" device, both used for one month, and (II) a 3-month open label stage to assess the long-term influence of the "active" device. Improvement of xerostomia severity from baseline was the primary outcome.
RESULTS: A total of 114 subjects were randomized. In Stage I, "active" device performed better than "sham" for patient-reported xerostomia severity (p<0.002), xerostomia frequency (p<0.05), quality of life impairment (p<0.01) and swallowing difficulty (p<0.02). At the end of Stage II, statistically significant improvements were verified for patient-reported xerostomia severity (p<0.0001), xerostomia frequency (p<0.0001), oral discomfort (p<0.001), speech difficulty (p<0.02) and sleeping difficulty (p<0.001), and for resting salivary flow-rate (p<0.01).
CONCLUSION: Daily use of the device alleviated oral dryness, discomfort and some complications of xerostomia, such as speech and sleeping difficulties, and increased salivary output. The results show a cumulative positive effect of the device over the period of the study, from baseline to the trial's end.
