NEW YORK, NY, August 14, 2012 /PRNewswire/ — According to a survey released by the Ad Council today less than half (44%) of parents in the U.S. report that their child brushes their teeth twice a day or more. In time for back-to-school season, the Ad Council is joining The Partnership for Healthy Mouths, Healthy Lives, a coalition of more than 35 leading dental health organizations, to debut Kids’ Healthy Mouths, their first joint national multimedia public service campaign designed to teach parents and caregivers, as well as children, about the importance of oral health and the simple ways in which they can help prevent oral disease. The English and Spanish-language public service ads are being distributed to media outlets nationwide today.
Dental decay is the most common chronic childhood disease with more than 16 million kids suffering from untreated tooth decay in the U.S. The mouth is the gateway to a person’s overall health, and an unhealthy mouth can be associated with obesity, diabetes and even heart disease. In the U.S., oral disease causes kids to miss 51 million school hours and their parents to lose 25 million work hours annually. Additionally, oral disease disproportionately affects children from low-income families and these children have almost twice the number of decayed teeth that have not been treated by a dentist as compared to others in the general population.
Created pro bono by ad agencies Grey Group and Wing in New York, the new Kids’ Healthy Mouths public service campaign is aimed at parents and caregivers throughout the U.S., particularly low-income families, and stresses the importance of brushing for 2 minutes twice a day.
According to the Ad Council survey released today, 60% of parents with children ages 12 or younger report that they do not regularly help their child brush their teeth or check to make sure they’ve done a good job. Additionally, close to one-third (31%) report arguing with their kids at least once a week about brushing their teeth. Parents also report that, on average, their child wastes over two hours each day on things that are silly or unnecessary, such as playing video games, texting, or watching an online video. The new campaign notes that some of this time could instead be focused on improving their oral health.
“The messages in this campaign may seem simple, but their impact will be felt for years to come,” said Gary Price, Secretary and CEO of the Dental Trade Alliance Foundation. “Most mouth disease is preventable using steps that can easily become a part of every child’s life routine. We are proud to be a part of such a broad partnership to help parents and caregivers learn how easy it is to protect their children, give them healthy mouths and help them lead healthy lives.”
The English and Spanish-language TV, radio, print, outdoor and digital PSAs poke fun at the myriad of inane things children spend their time doing and highlight that it only takes 2 minutes, twice a day to help maintain a healthy mouth and prevent future oral pain. An additional English and Spanish-language PSA features Elmo from Sesame Street singing to kids, reminding them to “Brushy Brush” their teeth every day as part of Sesame Street’s Healthy Teeth, Healthy Me campaign. The new campaign also includes a PSA featuring “Tooth” – the Tooth Fairy from Rise of the Guardians, the upcoming film from DreamWorks Animation SKG Inc..
“This is a great opportunity for Sesame Street to continue to use its influence to help families and their children make healthy decisions about oral health,” said Dr. Jeanette Betancourt, Senior Vice President for Outreach and Educational Practices, Sesame Workshop. “We are excited to partner with the Ad Council when nurturing children’s overall development is so critical and the subsequent positive effects can last a lifetime.”
“We are thrilled to work with the Ad Council and support this campaign by helping to convey the importance of oral health,” said Susan Spencer, DreamWorks Animation’s Head of National Promotions and Marketing Services.
All of the PSAs direct parents and caregivers to a new website, 2min2x.org (which is available in English and Spanish, and includes a mobile version), where parents and children can watch entertaining videos and listen to music—all 2 minutes in length—while children are brushing their teeth. Campaign media partners, including Cartoon Network and My Kazoo!, donated snippets of videos and songs for the site. A series of social media strategies will also be implemented to engage parents and children, including messaging on Facebook and Twitter and a dedicated YouTube channel, www.youtube.com/2min2x, where the 2-minute content will be featured.
"Joining the Ad Council for this worthy public service campaign is a unique opportunity for Cartoon Network and other youth entertainment media to serve together in supporting parents and children wellness," said Alice Cahn, vice president of social responsibility, Cartoon Network.
“As providers of entertainment to young children at MyKaZootv (www.mykazootv.com), we are especially concerned about their health and well being. Kids love music, and we hope our music videos help get kids brushing every day, twice a day. All the participating artists are proud to be part of the Ad Council campaign, “ said Rick Dobbis, co-founder of myKaZootv.
“The prevalence of oral disease, and its impact on youth in our country, is astounding,” said Peggy Conlon, president and CEO of the Ad Council. “We are proud to join this wonderful collaboration to provide parents and children with simple and fun things they can do to improve children’s oral health, and I’m delighted that so many of our partners in the advertising, media and entertainment industries have come forward to lend their talent, support and resources.”
This campaign is the first in the Ad Council’s 70 year history to address oral health. The Ad Council is distributing the new PSAs to more than 33,000 media outlets nationwide and the ads will air and run in advertising time and space entirely donated by the media. Several media companies have committed to supporting the PSAs prior to their launch.
“We were honored to assist the Ad Council in identifying strategic content partnerships for this worthy campaign. The importance of a healthy and beautiful smile resonates with the entertainment community, and providing 2-minute content is a fun and easy way for many partners to make a difference,” said Amy Tunick, President of Grey Alliance, the activation and public relations division of Grey Group.
“Oral health is a serious subject. When it concerns mothers and their children, the best creative approach is light and fun,” said Renata Florio, Chief Creative Officer of Wing, the Hispanic marketing agency of Grey Group. “Each commercial was intended to highlight the necessary balance of children’s time: if your child spends hours on playtime, why shouldn’t they spend 2 minutes taking care of their teeth? Working on the Ad Council Oral Health campaign was a pleasure and an important challenge for the agency.”
About the survey: The Ad Council survey was conducted online by LightSpeed Research June 19-25 with a sample of 601 English-speaking parents of children ages 0-12, from across the nation.

The effect of staining solutions on the colour stability of provisional prosthodontic materials


Available online 27 July 2012

Abstract

Objectives

The aim of this study was to evaluate the effects of staining solutions on the colour stability of self-cure provisional resin materials.

Methods

The specimens were prepared for each of three auto-polymerized bis-acryl resin and auto-polymerized methyl methacrylate provisional resin material. The baseline colour values were measured with a colorimeter according to the CIE L*a*b* colour scale. After the first measurement (T0), specimens were placed in staining solutions (coffee, coca-cola, burn and distilled water for control group) and the other measurements were taken after 24 h (T1), 1 week (T2) and 4 weeks (T3).

Results

Data were analyze statistically by (a) repeated measures (ANOVA), (b) one and two way ANOVA, and (c) Tukey HSD multiple comparison tests. At the 24 h immersion period, the post hoc analysis indicated that AccessCrown-coffee revealed the highest ΔE* values (4.4). At the second immersion period (1 week), Structur2 SC-coffee had the highest ΔE* values compared with other materials (5.4).

Conclusions

The degrees of discoloration were increased with immersion time. The methylmethacrylate resin was more resistant to discoloration than bis-acryl resins. After immersion for 30 days, the coffee solution resulted in unacceptable discoloration for all the tested materials.

A study of hydrogen peroxide chemistry and photochemistry in tea stain solution with relevance to clinical tooth whitening

Available online 31 July 2012

Abstract

Objective

Tooth whitening using hydrogen peroxide is a complex process, and there is still some controversy about the roles of pH, temperature, chemical activators, and the use of light irradiation. In this work the basic interactions between whitening agents and stain molecules are studied in simple solutions, thus avoiding the physics of diffusion and light penetration in the tooth to give clarity on the basic chemistry which is occurring.

Method

The absorbance of tea stain solution at 450 nm was measured over a period of 40 min, with various compositions of whitening agent added (including hydrogen peroxide, ferrous gluconate and potassium hydroxide) and at the same time the samples were subjected to blue light (465 nm) or infra-red light (850 nm) irradiation, or alternatively they were heated to 37 °C.

Results

It is shown that the reaction rates between chromogens in the tea solution and hydrogen peroxide can be accelerated significantly using ferrous gluconate activator and blue light irradiation. Infra red irradiation does not increase the reaction rate through photochemistry, it serves only to increase the temperature. Raising the temperature leads to inefficiency through the acceleration of exothermic decomposition reactions which produce only water and oxygen.

Conclusion

By carrying out work in simple solution it was possible to show that ferrous activators and blue light irradiation significantly enhance the whitening process, whereas infra red irradiation has no significant effect over heating. The importance of controlling the pH within the tooth structure during whitening is also demonstrated.

Wear evaluation of the human enamel opposing different Y-TZP dental ceramics and other porcelains

I am doing more and more zirconia based restorations.  You should try Zirconia crowns if you have not done so. MJ
Available online 10 August 2012

Abstract

Purpose

This study examined the wear resistance of human enamel and feldspathic porcelain after simulated mastication against 3 Zirconia ceramics, heat-pressed ceramic and conventional feldspathic porcelain.

Materials and methods

Human teeth and feldspathic porcelain cusp were tested against ceramic discs. 5 brands were tested- 3 monolithic zirconia, Prettau, Lava, and Rainbow, one lithium disilicate, IPS e.max Press, and one feldspathic porcelain, Vita-Omega 900. The surface was polished using a 600 grit and 1200 grit SiC paper. Each group was loaded for 300,000 cycles in a chewing simulator. The wear resistance was analyzed by measuring the volume of substance lost. The wear surfaces were observed by scanning electron microscopy to determine the wear characteristics.

Results

Vita-Omega 900 led to the greatest amount of enamel wear followed by IPS e.max Press, Prettau, Lava and Rainbow. There was a significant difference between Vita-Omega 900 and IPS e.max Press (p < 0.05). The wear values for human enamel were significantly greater than those for feldspathic porcelain, regardless of the surface roughness of the ceramic specimens (p < 0.05).

Conclusion

The wear behavior of human enamel and feldspathic porcelain varies according to the type of substrate materials. On the other hand, 3 zirconia ceramics caused less wear in the abrader than the conventional ceramic.

Clinical Significance

Dental professionals should be aware of the wear effect of dental restorations on the opposing teeth or restorations. The amount of enamel wear was highest in feldspathic porcelains whereas zirconia ceramics caused less wear on the opposing teeth.

The effect of aging on the pluripotential capacity and regenerative potential of human periodontal ligament stem cells.

Biomaterials. 2012 Oct;33(29):6974-86. Epub 2012 Jul 11.

Abstract

Multipotent postnatal stem cells can be isolated from human periodontal ligaments (PDLs) and have the potential for large-scale expansion, offering a reliable cell source for clinical use in periodontal regenerative therapies. However, the effects of aging on the mesenchymal stem cell (MSC) properties of these cells remain undefined. The aims of this study were to isolate and characterize the periodontal ligament stem cells (PDLSCs) derived from human impacted third molars of donors of different ages and to compare their pluripotential capacity and regenerative potential. PDL tissues were obtained from 90 surgically extracted third molars and divided into four groups according to the donor's age. For each group, the colony-forming ability, proliferative capacity, migratory potential, cell surface antigens, differentiation ability, alkaline phosphatase activity, and gene expression of the PDLSCs were contrastively evaluated and quantified for statistical analysis. The in vivo tissue regenerative potential of PDLSCs was assessed by an in vivo ectopic transplantation model. It was found that human PDLSCs were successfully isolated and characterized as MSCs in all 90 teeth. PDLSCs derived from donors of different ages were successfully differentiated under an osteogenic and adipogenic microenvironment. The proliferative and migratory potential and the differentiation capacity of PDLSCs decreased as age increased (p < 0.05). PDLSCs derived from donors whose age is 62.6 ± 6.8 have a statistically significant decrease in pluripotential capacity compared with those derived from relatively young donors (p < 0.01). There is no identified cementum and PDL-like tissue formation in vivo among the two aging groups. We conclude that human PDLSCs could be successfully isolated from PDL tissue derived from donors of different ages, but the age-related changes of the MSC properties should be taken into account whenever they are intended for use in research or cytotherapy.

Comparison of variable-thread tapered implant designs to a standard tapered implant design after immediate loading. A 3-year multicentre randomised controlled trial.

Eur J Oral Implantol. 2012 Summer;5(2):123-36.

Abstract

Objectives: This randomised, controlled multicentre trial aimed at comparing two versions of a variable-thread dental implant design to a standard tapered dental implant design in cases of immediate functional loading for 36 months after loading. Materials and methods: 177 patients (325 implants) were included at 12 study centres and randomly allocated into one of three treatment groups: NAI (variable-thread design, NobelActive internal connection), NAE (variable-thread design, NobelActive external connection) and, as control, NR (standard tapered design, NobelReplace tapered groovy). Inclusion criteria concerned healed bony implant sites and feasibility for immediate loading. Clinical and radiographic examinations were performed at implant placement and after 3, 6, 12, 24 and 36 months. The outcome measures were marginal bone remodelling (primary outcome), implant survival and success, papilla score, plaque accumulation, and bleeding on probing. Results: 127 patients (NAI: 45, NAE: 41, NR: 41) were followed-up and evaluated after 36 months. No significant differences in cumulative survival rates were seen for the groups (NAI: 95.7%; NAE: 96.3%; NR: 96.6%). In all groups, bone remodelling occurred during the first 3 months, with stable or even increasing bone levels after the initial remodelling period. The bone remodelling from insertion to 36 months for the NAI group (-0.89 ± 1.65 mm) was comparable (P = 0.98) to that of the NR group (-0.85 ± 1.32 mm). The NAE group showed comparable bone remodelling during the first year, with an increase in following years resulting in significantly less overall bone loss (-0.16 ± 1.06 mm) (P = 0.041). Overall improvement in papilla size was observed in all treatment groups. Conclusions: Over 36 months, the results show stable or improving bone levels for all treatment groups after the initial bone remodelling seen during the first 3 months after placement. The variable- thread implants showed results comparable to those of standard tapered implants in cases of immediate function, and therefore can be considered as a treatment option for immediate loading.

Microflora associated with primary endodontic infections: correlations among sem evaluation, clinical features, and radiographic findings

Razera Baldasso, F. E., Stürmer, C. P., Luisi, S. B., Rodrigues Petruzzi, M. N. M., SCARPARO, R. K. and Figueiredo, J. A. P. D. (2012), Microflora associated with primary endodontic infections: correlations among sem evaluation, clinical features, and radiographic findings. Microsc. Res. Tech.. doi: 10.1002/jemt.22100

Abstract

The aim of the present study was to characterize, by means of SEM, primary endodontic infections and to correlate with clinical and radiographic findings. Twelve (12) human extracted teeth (19 roots) presenting primary endodontic infection were examined. SEM qualitative observations of bacterial and defense cells, their features and distribution within the root canal lumen and root dentine were recorded for association with clinical and radiographic tabled data. Although a direct correlation between biofilm composition and clinical/radiographic findings was not established, structural organization and distribution of the biofilm, as well as the characteristics of host response, could be easily related to those features. Bacterial biofilm was predominant at the apical third. Symptomatic apical periodontitis was related to presence of bacterial biofilm all thirds. Defense cells could be seen in the apical third of some samples. These cells were present in all thirds in some of the cases with open cavities. The correlations performed in this study allowed a better understanding of the picture of primary endodontic infection, host response and relevant clinical features. The combined use of scanning electron microscopy with clinical and radiographic evaluation has the potential to overcome some limits of the current knowledge related to pulpal and periapical diseases, providing important insights for improving treatment strategies.

Carestream Dental Announces New Version of Logicon Caries Detector™ Software is Now Available

  Software’s Update Includes PreScan Feature 
that Further Automates the Caries Detection Process

ATLANTA – Carestream Dental today announced the availability of Logicon Caries DetectorTM Software version 5.0.22.4. Logicon Software is a computer-aided detection tool that helps dentists identify and treat more interproximal caries at an early stage for improved patient care. The software’s new PreScan feature streamlines the analysis process and interface to improve practice efficiency.

Exclusively designed to work with images captured by Carestream Dental’s best-in-class RVG sensors, Logicon Software is clinically proven to help dentists find more interproximal carious lesions than with traditional methods such as visual examinations of radiographs or oral examinations.*

Using detection and classification algorithms, Logicon Software automatically highlights possible abnormalities in dental radiographs, calculates the probability that decay is present and recommends whether a restoration should be considered. Results are displayed based on a database of histological validated caries. The software extracts image features and correlates them with a database of known caries problems.

New for Logicon Software is the addition of a PreScan feature that further automates caries detection and improves practice efficiency. With a single click, practitioners can use the PreScan feature to automatically scan all interproximal surfaces in a bitewing radiograph and immediately display the results, instead of having to scan one interproximal surface at a time. Dentists then have access to an index of the results that correlate to each interproximal surface. This provides practitioners with an initial assessment of the state of caries.

“The PreScan feature is intended to focus dentists’ attention on the interproximal surfaces they should evaluate further for treatment or monitoring,” said Dr. David Gakenheimer, Logicon Software product line manager for Carestream Dental. “The software makes it easy for dentists to explore sensitive sites in patients’ mouths by saving detailed results for each PreScan surface that they can view and adjust if necessary to find the deepest extent of the caries.”

Additional features of Logicon Software include a region of interest (ROI) adjustment tool that automatically searches to find maximum caries depth, as well as a zoom tool that allows practitioners to focus on specific regions. The software also makes working with third parties easier, as information and screenshots can be quickly sent via the software’s email function.

Logicon Software is fully integrated with CS Dental Imaging Software, and the new PreScan feature is designed for use with RVG 6100 and RVG 6500 bitewing images. This latest version of the software is now available for sale.

“While there is no substitute for personal care and regular dental checkups, our Logicon Software makes examinations more efficient and effective,” said Edward Shellard, D.M.D., chief marketing officer and director of business development for Carestream Dental. “Logicon PreScan provides practitioners with an electronic second opinion. The tool offers a more precise method of determining the presence of caries, streamlines the analysis process and includes an easy-to-understand display that helps dentists better communicate patient conditions and treatment recommendations, which ultimately leads to greater case acceptance.”

Mechanisms of action of systemic antibiotics used in periodontal treatment and mechanisms of bacterial resistance to these drugs

J. Appl. Oral Sci. vol.20 no.3 Bauru May/June 2012


ABSTRACT
Antibiotics are important adjuncts in the treatment of infectious diseases, including periodontitis. The most severe criticisms to the indiscriminate use of these drugs are their side effects and, especially, the development of bacterial resistance. The knowledge of the biological mechanisms involved with the antibiotic usage would help the medical and dental communities to overcome these two problems. Therefore, the aim of this manuscript was to review the mechanisms of action of the antibiotics most commonly used in the periodontal treatment (i.e. penicillin, tetracycline, macrolide and metronidazole) and the main mechanisms of bacterial resistance to these drugs. Antimicrobial resistance can be classified into three groups: intrinsic, mutational and acquired. Penicillin, tetracycline and erythromycin are broad-spectrum drugs, effective against gram-positive and gram-negative microorganisms. Bacterial resistance to penicillin may occur due to diminished permeability of the bacterial cell to the antibiotic; alteration of the penicillin-binding proteins, or production of β-lactamases. However, a very small proportion of the subgingival microbiota is resistant to penicillins. Bacteria become resistant to tetracyclines or macrolides by limiting their access to the cell, by altering the ribosome in order to prevent effective binding of the drug, or by producing tetracycline/macrolide-inactivating enzymes. Periodontal pathogens may become resistant to these drugs. Finally, metronidazole can be considered a prodrug in the sense that it requires metabolic activation by strict anaerobe microorganisms. Acquired resistance to this drug has rarely been reported. Due to these low rates of resistance and to its high activity against the gram-negative anaerobic bacterial species, metronidazole is a promising drug for treating periodontal infections.

The Challenges Of Improving The Oral Health Of Adults With Special Needs

A comprehensive study using electronic dental records to profile the oral health status of adults with intellectual and developmental disabilities (I/DD) has concluded that access to specialized dental care alone is not sufficient to meet the community's substantial oral health needs. The findings, published as the cover article in the August issue of The Journal of the American Dental Association, provide a foundation for further investigation into the significant oral health needs of adults with I/DD and the development of preventive oral health strategies.

The study of dental records of 4,732 people, led by dentists and public health professionals at Tufts University School of Dental Medicine (TUSDM) and Tufts University School of Medicine (TUSM), was conducted at the Tufts Dental Facilities Serving People with Special Needs (TDF), a network of Massachusetts dental clinics that provides oral health care to people with disabilities.

Each year, Tufts' program, which is recognized by the Association of State & Territorial Dental Directors as a national model, serves more than 7,000 patients at seven clinics in Massachusetts. The findings released today are the first of a three-part study conducted by principal investigators John Morgan, D.D.S., associate professor in the department of public health and community service at TUSDM, and Paula Minihan, Ph.D., M.P.H., assistant professor in the department of public health and community medicine at TUSM.

"People with intellectual and developmental disabilities are more likely to have poor oral hygiene, periodontal disease and untreated tooth decay than the general population," said Morgan. "Our findings highlight the need for greater awareness of the unique and complex dental health care needs of this population. The roles of the patient, care giver and dental provider are all vital in developing preventive strategies to improve oral health."

Morgan and colleagues analyzed clinical and demographic data documented in electronic dental records over a one-year period. They investigated oral health conditions (e.g. dental caries (cavities), periodontal (gum) disease, etc.), age, gender, ability to receive dental examinations and procedures, level of disability, and type of residence. Of the 4,732 patients whose records were reviewed, 61% were reported to have a mild to moderate disability, and 39% were assessed as having a severe disability. Dental records revealed a high burden of oral disease, including dental caries (cavities), periodontitis (gum disease) and missing teeth.

Nearly 25% of the patients had a limited ability to accept any dental intervention and required specialized resources, such as general anesthesia. Almost 40% of all patients able to accept dental treatment required some form of behavioral assistance. These behavioral challenges pose difficulties for dental staff when providing diagnostic and therapeutic procedures. "Behavioral challenges present barriers to good oral health and overall health," Morgan said. "Often patients with significant developmental disabilities cannot tolerate complex and time consuming dental treatments."

"From a public health perspective, our findings signal the need for the development of best practices for dental treatment guidelines that promote and protect the oral health of this vulnerable population," said co-investigator Aviva Must, Ph.D., professor and dean of public health and professional degree programs at TUSM. "Further research is required to identify and develop risk-based preventive interventions to manage oral diseases for people with intellectual or developmental disabilities and maximize the role of the dental professional, patient, and caregiver in promoting oral health."

ELEVEN YEAR SURVIVAL OF BRIDGES PLACED IN THE GENERAL DENTAL SERVICES IN ENGLAND AND WALES

Patients are always asking this question, so now here is the latest research to answer the question. MJ
Available online 2 August 2012

Aim

It is the aim of this paper to consider the factors associated with the need for re-intervention on a conventional or resin-retained bridge, excluding recementation.

Methods

A data set was established consisting of patients, eighteen years or older, whose birthdays were included within a set of randomly selected dates, one of which was chosen in each possible year of birth and whose restoration records contained the placement of one or more indirect restorations on courses of treatment with last date on the claim form after 31st December 1990, and with date of acceptance after September 1990 and before January 2002. For each patient treated with a bridge, the subsequent history of intervention on each tooth used as a bridge abutment was consulted, and the next date of intervention, if any could be found in the extended data set, was obtained. Thus a data set was created of bridge abutments which have been placed, with their dates of placement and their dates, if any, of re-intervention.

Results

Data for over 80,000 different adult patients were analysed, of whom 46% were male and 54% female. A total of 7,874 abutments (6,800 conventional and 1,074 resin-retained) were obtained from the data over a period of eleven years.
Factors which were found to reduce outcome of bridges included type of bridge, patient payment exemption status, patient attendance pattern and position of the bridge in the patient's mouth.

Conclusions

Survival of conventional bridge abutments has been shown to be 72% at 10 years, this being similar survival time to crowns. Various patient factors and bridge type were also found to influence survival.

Coalition of More Than 35 Leading Dental Organizations Joins Ad Council to Launch First Campaign on Children’s Oral Health

Campaign partners include Sesame Street, DreamWorks Animation, Cartoon Network, MyKazoo!, Grey Group and Wing

NEW YORK, NY, August 14, 2012 /PRNewswire/ — According to a survey released by the Ad Council today less than half (44%) of parents in the U.S. report that their child brushes their teeth twice a day or more. In time for back-to-school season, the Ad Council is joining The Partnership for Healthy Mouths, Healthy Lives, a coalition of more than 35 leading dental health organizations, to debut Kids’ Healthy Mouths, their first joint national multimedia public service campaign designed to teach parents and caregivers, as well as children, about the importance of oral health and the simple ways in which they can help prevent oral disease. The English and Spanish-language public service ads are being distributed to media outlets nationwide today.
Dental decay is the most common chronic childhood disease with more than 16 million kids suffering from untreated tooth decay in the U.S. The mouth is the gateway to a person’s overall health, and an unhealthy mouth can be associated with obesity, diabetes and even heart disease. In the U.S., oral disease causes kids to miss 51 million school hours and their parents to lose 25 million work hours annually. Additionally, oral disease disproportionately affects children from low-income families and these children have almost twice the number of decayed teeth that have not been treated by a dentist as compared to others in the general population.
Created pro bono by ad agencies Grey Group and Wing in New York, the new Kids’ Healthy Mouths public service campaign is aimed at parents and caregivers throughout the U.S., particularly low-income families, and stresses the importance of brushing for 2 minutes twice a day.
According to the Ad Council survey released today, 60% of parents with children ages 12 or younger report that they do not regularly help their child brush their teeth or check to make sure they’ve done a good job. Additionally, close to one-third (31%) report arguing with their kids at least once a week about brushing their teeth. Parents also report that, on average, their child wastes over two hours each day on things that are silly or unnecessary, such as playing video games, texting, or watching an online video. The new campaign notes that some of this time could instead be focused on improving their oral health.
“The messages in this campaign may seem simple, but their impact will be felt for years to come,” said Gary Price, Secretary and CEO of the Dental Trade Alliance Foundation. “Most mouth disease is preventable using steps that can easily become a part of every child’s life routine. We are proud to be a part of such a broad partnership to help parents and caregivers learn how easy it is to protect their children, give them healthy mouths and help them lead healthy lives.”
The English and Spanish-language TV, radio, print, outdoor and digital PSAs poke fun at the myriad of inane things children spend their time doing and highlight that it only takes 2 minutes, twice a day to help maintain a healthy mouth and prevent future oral pain. An additional English and Spanish-language PSA features Elmo from Sesame Street singing to kids, reminding them to “Brushy Brush” their teeth every day as part of Sesame Street’s Healthy Teeth, Healthy Me campaign. The new campaign also includes a PSA featuring “Tooth” – the Tooth Fairy from Rise of the Guardians, the upcoming film from DreamWorks Animation SKG Inc..
“This is a great opportunity for Sesame Street to continue to use its influence to help families and their children make healthy decisions about oral health,” said Dr. Jeanette Betancourt, Senior Vice President for Outreach and Educational Practices, Sesame Workshop. “We are excited to partner with the Ad Council when nurturing children’s overall development is so critical and the subsequent positive effects can last a lifetime.”
“We are thrilled to work with the Ad Council and support this campaign by helping to convey the importance of oral health,” said Susan Spencer, DreamWorks Animation’s Head of National Promotions and Marketing Services.
All of the PSAs direct parents and caregivers to a new website, 2min2x.org (which is available in English and Spanish, and includes a mobile version), where parents and children can watch entertaining videos and listen to music—all 2 minutes in length—while children are brushing their teeth. Campaign media partners, including Cartoon Network and My Kazoo!, donated snippets of videos and songs for the site. A series of social media strategies will also be implemented to engage parents and children, including messaging on Facebook and Twitter and a dedicated YouTube channel, www.youtube.com/2min2x, where the 2-minute content will be featured.
"Joining the Ad Council for this worthy public service campaign is a unique opportunity for Cartoon Network and other youth entertainment media to serve together in supporting parents and children wellness," said Alice Cahn, vice president of social responsibility, Cartoon Network.
“As providers of entertainment to young children at MyKaZootv (www.mykazootv.com), we are especially concerned about their health and well being. Kids love music, and we hope our music videos help get kids brushing every day, twice a day. All the participating artists are proud to be part of the Ad Council campaign, “ said Rick Dobbis, co-founder of myKaZootv.
“The prevalence of oral disease, and its impact on youth in our country, is astounding,” said Peggy Conlon, president and CEO of the Ad Council. “We are proud to join this wonderful collaboration to provide parents and children with simple and fun things they can do to improve children’s oral health, and I’m delighted that so many of our partners in the advertising, media and entertainment industries have come forward to lend their talent, support and resources.”
This campaign is the first in the Ad Council’s 70 year history to address oral health. The Ad Council is distributing the new PSAs to more than 33,000 media outlets nationwide and the ads will air and run in advertising time and space entirely donated by the media. Several media companies have committed to supporting the PSAs prior to their launch.
“We were honored to assist the Ad Council in identifying strategic content partnerships for this worthy campaign. The importance of a healthy and beautiful smile resonates with the entertainment community, and providing 2-minute content is a fun and easy way for many partners to make a difference,” said Amy Tunick, President of Grey Alliance, the activation and public relations division of Grey Group.
“Oral health is a serious subject. When it concerns mothers and their children, the best creative approach is light and fun,” said Renata Florio, Chief Creative Officer of Wing, the Hispanic marketing agency of Grey Group. “Each commercial was intended to highlight the necessary balance of children’s time: if your child spends hours on playtime, why shouldn’t they spend 2 minutes taking care of their teeth? Working on the Ad Council Oral Health campaign was a pleasure and an important challenge for the agency.”
About the survey: The Ad Council survey was conducted online by LightSpeed Research June 19-25 with a sample of 601 English-speaking parents of children ages 0-12, from across the nation.

Carestream Dental’s RVG Digital Radiography Celebrates 30 Years

 
Company Builds on World’s First Digital Intraoral Radiography Sensor;
Continues to Offer Practices Innovative Imaging Solutions
 
ATLANTA – The dental industry was changed forever with the advent of RadioVisioGraphy (RVG) in 1982, and now Carestream Dental is celebrating its 30th year of providing dental practitioners worldwide with unparalleled image quality. Invented and patented by visionary French dentist Dr. Francis Mouyen, RVG imaging delivers digital images instantly, creating a more efficient workflow for practices and improving patient communication.

Since its introduction, RVG has established a continuing tradition of innovation in digital radiography, including milestones such as offering the first sensor to provide >20 lp/mm resolution and a wireless sensor that can easily be shared between operatories. Today, Carestream Dental’s RVG family features three sensor options for practitioners.

Serving as entry point into digital dental radiography, the RVG 5100 provides practices with an ideal solution for basic intraoral imaging needs. With two sensor sizes available, this system is easy to use and delivers exceptional images (true resolution of 14 lp/mm) in seconds.

Introduced in 2006, the RVG 6100 offers the highest image resolution in the industry (>20 lp/mm) and delivers images in seconds. Perfect for multi-chair practices, this system is designed to streamline workflow with easy image capture, analysis and sharing. RVG 6100 sensors are available in three sizes, including a size 0 sensor for pediatric applications.

Delivering the same, best-in-class image quality as wired RVG 6100 sensors, the RVG 6500 system (introduced in 2010) uses proven Wi-Fi technology to eliminate the need for the sensors to have a wired connection to a computer. Offering unprecedented imaging flexibility, this system can be used in a variety of practice configurations, including multi-sensor and multi-computer environments. Available in three sizes, RVG 6500 sensors transfer images to operatory computers within seconds.

“The introduction of RVG imaging caused a significant shift in the oral health industry – a shift towards digital technology,” said Edward Shellard, D.M.D., chief marketing officer and director of business development for Carestream Dental. “Over the years, we’ve continued to develop and strengthen our offerings in the digital radiography category so our products meet clinicians’ diagnostic needs, integrate into practice workflows and are easy to use. From the invention of the digital sensor to the introduction of a wireless sensor that offers the highest image resolution, our line of RVG products has evolved to serve the ever-changing needs of our customers and their patients.”

Carestream Dental’s current RVG solutions integrate seamlessly with the company’s various imaging software programs. Additionally, Logicon Caries DetectorTM Software serves as a computer-aided diagnostic tool that helps practitioners locate and diagnose interproximal caries using a database of known caries problems.

In addition to unsurpassed image resolution and software integration, Carestream Dental’s RVG sensors are built with rounded corners and rear-entry cables to ensure patients are comfortable. All sensors are also built with shock-resistant casing, providing maximum durability for a long lifespan.

The Effect of Ozone alone and in combination with adjunct remineralisation products on Inhibition of Demineralisation of the Dental Hard Tissues. in situ

Available online 31 July 2012
In Press, Accepted Manuscript 

 Abstract

Objectives

In the United Kingdom Ozone therapy combines the use of ozone gas and adjunct products called reductant and the patient kit, which all contain fluoride. We studied the effect of these products with and without the use of ozone in inhibiting demineralisation of human enamel and dentine under a cariogenic challenge in situ.

Methods

A single-blind, randomised, three legs, cross-over study design was used. Fourteen volunteers were provided with a lower removable intra-oral appliance carrying one enamel and one dentine slabs. Baseline measurements of enamel and dentine hardness slabs were recorded. The study regime of 14 days of dipping into 10% sucrose solution five times a day was applied. The three legs were two test groups Ozone/Reductant/Patient Kit, Reductant/Patient Kit, and a Fluoride free toothpaste group as a control. At the end of the 2nd week the slabs were collected, microhardness measured and the differences from the baselines were calculated.

Results

There were statistically significant differences in the mean changes of enamel and dentine hardness when both test groups were compared individually with the control. However, no statistical significant differences in either parameter was found when Ozone/Reductant/Patient Kit group was compared with Reductant/Patient Kit treatment.

Conclusions

We conclude from these results that ozone had no additional effect on the inhibition of enamel and dentine demineralisation than when Reductant/Patient Kit, containing high concentrations of Fluoride, were used on their own.

The effects of light on bleaching and tooth sensitivity during in-office vital bleaching: A systematic review and meta-analysis

Journal of Dentistry
Volume 40, Issue 8 , Pages 644-653, August 2012

Abstract 

Objective

To evaluate the influence of light on bleaching efficacy and tooth sensitivity during in-office vital bleaching.

Data sources

We performed a literature search using Medline, EMBASE and Cochrane Central up to September 2011.

Study selection

All randomised controlled trials (RCTs) or quasi-RCTs comparing the light-activated bleaching system with non-activation bleaching system were included. Reports without clinical data concerning bleaching efficacy or tooth sensitivity were excluded.

Results

Eleven studies were included in the meta-analysis. A light-activated system produced better immediate bleaching effects than a non-light system when lower concentrations of hydrogen peroxide (15–20% HP) were used (mean difference [MD], −1.78; 95% confidence interval [CI]: [−2.30, −1.26]; P<0.00001). When high concentrations of HP (25–35%) were employed, there was no difference in the immediate bleaching effect (MD, −0.39; 95% CI: [−1.15, 0.37]; P=0.32) or short-term bleaching effect (MD, 0.25; 95% CI: [−0.47, 0.96]; P=0.50) between the light-activated system and the non-light system. However, the light-activated system produced a higher percentage of tooth sensitivity (odds ratio [OR], 3.53; 95% CI: [1.37, 9.10]; P=0.009) than the non-light system during in-office bleaching.

Conclusions

Light increases the risk of tooth sensitivity during in-office bleaching, and light may not improve the bleaching effect when high concentrations of HP (25–35%) are employed. Therefore, dentists should use the light-activated system with great caution or avoid its use altogether. Further rigorous studies are, however, needed to explore the advantages of this light-activated system when lower concentrations of HP (15–20%) are used.
