A six-year prospective randomized study of a nano-hybrid and a conventional hybrid resin composite in Class II restorations

Dental Materials
Volume 29, Issue 2 , Pages 191-198, February 2013



The objective of this 6 year prospective randomized equivalence trial was to evaluate the long-term clinical performance of a new nano-hybrid resin composite (RC) in Class II restorations in an intraindividual comparison with its well-established conventional hybrid RC predecessor.


Each of 52 participants received at least two, as similar as possible, Class II restorations. The cavities were chosen at random to be restored with an experimental nano-hybrid RC (Exite/Tetric EvoCeram (TEC); n=61) and a conventional hybrid RC (Exite/Tetric Ceram (TC); n=61). The restorations were evaluated with slightly modified USPHS criteria at baseline and then annually during 6 years.


Two patient drop outs with 4 restorations (2TEC, 2TC) were registered during the follow-up. A prediction of the caries risk showed that 16 of the evaluated 52 patients were considered as high risk patients. Eight TEC (2 P, 6M) and 6 TC (2P, 4M) restorations failed during the 6 years. The main reason of failure was secondary caries (43%; including the failure fracture+secondary caries it increases to 57.1%). 63% of the recurrent caries lesions were found in high caries risk participants. The overall success rate at six years was 88.1%. No statistical significant difference was found in the overall survival rate between the two investigated RC.


The nano-hybrid RC showed good clinical performance during the 6 year evaluation, comparable to the well-established conventional hybrid RC.

For the strongest temporary crowns and bridges: Kettenbach adds Visalys® Temp to its portfolio

Huntington Beach, CA, January 21, 2013 – Dental products specialist Kettenbach LP ( has introduced new Visalys® Temp. With this development, Kettenbach sets new materials standards for provisional crowns and bridges. Visalys® Temp ensures demonstrably stronger temporaries that are highly aesthetic and more fracture-resistant and manufactured without BPA. Scientific studies at the University of Erlangen and extensive user testing have confirmed these properties.

A dental laboratory needs one to four weeks to fabricate a permanent bridge or crown. Temporary crowns or bridges are made for this period so the patient is not impaired in terms of dental health or appearance. For these provisional solutions, stability and aesthetic result are top priorities for both patient and dentist.

Kettenbach’s new product Visalys® Temp is a two-component BPA free resin based on a multifunctional acrylic composite. It can be used to make highly aesthetic temporary crowns, partial crowns, bridges, inlays, onlays, and veneers including long-term provisionals. Now dentists can make provisional restorations with Visalys® Temp that are remarkably stable and fracture resistant due to its unique, new monomer structure.

Tests demonstrate a particularly strong, aesthetic and comfortable result
Scientific studies at the University of Erlangen, as well as extensive clinical practice tests, prove that Visalys® Temp has excellent mechanical properties in comparison with leading competitor products. The stability and fracture resistance of a crown and bridge material are defined by six main parameters: bending strength, impact strength, diametral tensile strength, elastic modulus, fatigue factor, and Barcol hardness. In an independent in vivo market study, dentists rated provisional restorations made of Visalys® Temp as being clearly more break-resistant than other manufacturers’ temporaries; 90 percent of those surveyed said they would switch to Visalys® Temp.

In addition, the material is easy-to-use and guarantees superior aesthetic results in addition to stability. The smooth surface ensures a pleasant feeling in the mouth and impedes plaque formation. Visalys® Temp can be precisely milled and minimizes dust formation. Its natural fluorescence and translucency are optimal for restorations of front teeth. Visalys® Temp also contains no bisphenol A, a substance suspected of impairing health.

Internet Access Plan- PACE?

I was listening to a Podcast the other day and there was a discussion about Internet access. Now for me, Internet access is something I take for granted except when I don't have it. Recent examples are after Hurricane Sandy I lost both my house and office Internet service along with my primary cell phone service and data. At this point in time data is more important to me then telephone service. So what is PACE in regards to Internet Access.  Pace stands for






So it got me to thinking, what is my PACE?

For me it is my primary Internet Providers

At Home:
P- Cablevison
A- iPad mini Hot Spot (Verizon) 4G
C- iPhone as a  Hot Spot  (Sprint) 3G
E- Activate old iPhone as a Hot Spot (AT&T) 3G

During the hurricane I did not have this protocol thought out. I lost my primary Internet and Sprint service disappeared across my entire county. So I was roaming on Verizon but frequently drove to places to try and get access.

At my Office
P- Comcast
A- Verizon DSL
C- iPad mini as a hot spot (Verizon) 4G
E- iPhone as a  Hot Spot  (Sprint) 3G

So think about your Internet access plan in the event of an emergency or service disruption.

What's Your PACE ?

Evaluation of marginal and internal fit of ceramic crown copings

Dental Materials
Volume 29, Issue 2 , Pages 174-180, February 2013



(1) To measure the marginal and internal adaptation of different prosthetic crowns infrastructures (IS); (2) to analyze two types of methodologies (replica and weight technique) used to evaluate the adaptation of indirect restorations.


Ceramic IS were fabricated using CAD/CAM technology and slip-casting technique, and metal IS were produced by casting (n=10). For each experimental group, the adaptation was evaluated with the replica (RT) and the weight technique (WT), using an impression material (low viscosity silicon) to simulate the luting agent. Cross-sectional images of the silicon replica were obtained and analyzed with Image J software to measure the low viscosity silicon layer thickness at pre-determined points. The silicon layer was also weighted. Results were statistically analyzed with ANOVA and Tukey's test (α=0.05). Pearson correlation was used to analyze the relation between the two types of evaluation methods.


All IS evaluated showed clinically acceptable internal and marginal adaptation. Metal IS showed the best adaptation, irrespective of the measuring technique (RT and WT). The IS produced by CAD–CAM showed greater gap values at the occlusal area than at other evaluated regions. The IS produced by the dental laboratory technician showed similar gap values at all evaluated regions. There is no correlation between RT and WT (p>0.05).


Different levels of adaptation were found for the different experimental groups and for the different evaluation methods. However, all IS evaluated showed clinically acceptable values of marginal and internal adaptation.

All on Four® Fixed Implant Support Rehabilitation: A Masticatory Function Study

De Rossi, M., Santos, C. M., Migliorança, R. and Regalo, S. C. H. (2013), All on Four® Fixed Implant Support Rehabilitation: A Masticatory Function Study. Clinical Implant Dentistry and Related Research. doi: 10.1111/cid.12031



Fixed implant-supported prostheses according to All-on-Four® (Nobel Biocare, Goteborg, Sweden) principles have become an accepted treatment modality in totally edentulous patients, whereas the functional effect of this therapy is limited.


The purpose of this study was to evaluate the muscular function of patients totally rehabilitated with All-on-Four.

Materials and Methods

This study evaluated 63 patients. Twenty-one patients were successfully rehabilitated with maxillary and mandibular All-on-Four (no dropout implants, satisfactory aesthetic and function demands prosthesis), 21 patients were dentate, and 21 were rehabilitated with double complete dentures. Electromyography was carried out during clenching, nonhabitual and habitual chewing, and rest. All values were standardized as percentage of a maximum voluntary contraction. Data were analyzed by ANOVA to compare groups and paired t-test was used for comparison between sides within each group.


All groups presented symmetric muscular activity. The All-on-Four and dentate groups had a similar muscles surface electromyography (sEMG) contraction pattern, that is, a higher sEMG activity of masseter than temporalis muscles, differing (p ≤ .05) from those of denture group. Not one statistical difference was found between All-on-Four and dentate groups.


The muscular function similarity of All-on-Four and dentate patients shows that this treatment concept may be considered as a good option for oral rehabilitation in edentulous patients.

Shear bond strength of one-step self-etch adhesives to enamel: effect of acid pretreatment

Poggio, C., Scribante, A., Della Zoppa, F., Colombo, M., Beltrami, R. and Chiesa, M. (2013), Shear bond strength of one-step self-etch adhesives to enamel: effect of acid pretreatment. Dental Traumatology. doi: 10.1111/edt.12027



The purposes of this study were to evaluate the effect of surface pretreatment with phosphoric acid on the enamel bond strength of four-one-step self-etch adhesives with different pH values.

Material and methods

One hundred bovine permanent mandibular incisors were used. The materials used in this study included four-one-step self-etch adhesives with different pH values: Adper Easy Bond Self-Etch Adhesive (ph = 0,8-1), Futurabond NR (ph = 1,4), G-aenial Bond (ph = 1,5), Clearfil3S Bond (ph = 2,7). One two-step self-etch adhesive (Clearfil SE Bond/ph = 0,8-1) was used as control. The teeth were assigned into two subgroups according to bonding procedure. In the first subgroup (n = 50), no pretreatment agent was applied. In the second subgroup (n = 50), etching was performed using 37% phosphoric acid for 30 s. After adhesive systems application, a nanohybrid composite resin was inserted into the enamel surface. The specimens were placed in a universal testing machine (Model 3343, Instron Corp., Canton, Mass., USA). After the testing procedure, the fractured surfaces were examined with an optical microscope at a magnification of 10× to determine failure modes. The adhesive remnant index (ARI) was used to assess the amount of adhesive left on the enamel surface.


Descriptive statistics of the shear bond strength and frequency distribution of ARI scores were calculated.


Enamel pretreatment with phosphoric acid significantly increased bond strength values of all the adhesives tested. No significant differences in bond strength were detected among the four different one-step self-etch adhesives with different pH. Two-step self-etch adhesive showed the highest bond strength.

Comparison of caries detection methods using varying numbers of intra-oral digital photographs with visual examination for epidemiology in children

I use photography as part of every new patient exam and believe it is an excellent method for detecting caries. MJ

BMC Oral Health 2013, 13:6 doi:10.1186/1472-6831-13-


This was a method comparison study. The aim of study was to compare caries information obtained from a full mouth visual examination using the method developed by the British Association for the Study of Community Dentistry (BASCD) for epidemiological surveys with caries data obtained from eight, six and four intra-oral digital photographs of index teeth in two groups of children aged 5 years and 10/11 years.


Five trained and calibrated examiners visually examined the whole mouth of 240 5-year-olds and 250 10-/11-year-olds using the BASCD method. The children also had intra-oral digital photographs taken of index teeth. The same 5 examiners assessed the intra-oral digital photographs (in groups of 8, 6 and 4 intra-oral photographs) for caries using the BASCD criteria; dmft/DMFT were used to compute Weighted Kappa Statistic as a measure of intra-examiner reliability and intra-class correlation coefficients as a measure of inter-examiner reliability for each method. A method comparison analysis was performed to determine the 95% limits of agreement for all five examiners, comparing the visual examination method with the photographic assessment method using 8, 6 and 4 intra-oral photographs.


The intra-rater reliability for the visual examinations ranged from 0.81 to 0.94 in the 5-year-olds and 0.90 to 0.97 in the 10-/11-year-olds. Those for the photographic assessments in the 5-year-olds were for 8 intra-oral photographs, 0.86 to 0.94, for 6 intra-oral photographs, 0.85 to 0.98 and for 4 intra-oral photographs, 0.80 to 0.96; for the 10-/11-year-olds were for 8 intra-oral photographs 0.84 to 1.00, for 6 intra-oral photographs 0.82 to 1.00 and for 4 intra-oral photographs 0.72 to 0.98. The 95% limits of agreement were -1.997 to 1.967, -2.375 to 2.735 and -2.250 to 2.921 respectively for the 5-year-olds and -2.614 to 2.027, -2.179 to 3.887 and -2.594 to 2.163 respectively for the 10-/11-year-olds.


The photographic assessment method, particularly assessment of 8 intra-oral digital photographs is comparable to the visual examination method in the primary dentition. With the additional benefits of archiving, remote scoring, allowing multiple scorers to score images and enabling longitudinal analysis, the photographic assessment method may be used as an alternative caries detection method in the primary dentition in situations where the visual examination method may not be applicable such as when examiner blinding is required and in practice based randomised controlled trials (RCTs).

nfluence of mouthguards on the physical performance of soccer players

Queiróz, A. F. V. R., de Brito Jr, R. B., Ramacciato, J. C., Motta, R. H. L. and Flório, F. M. (2013), Influence of mouthguards on the physical performance of soccer players. Dental Traumatology. doi: 10.1111/edt.12026



To evaluate the influence of different types of mouthguard (MG) on physical performance of female soccer players.

Material and methods

The sample was composed of 25 female soccer players from ‘Guarani Futebol Clube’, age range 18–22 years. For data collection, two tests were performed: agility test (shuttle run) and aerobic capacity and VO2 (Cooper test), in addition to application of a perception questionnaire after wearing mouthguards during the tests.


Data analysis showed that mouthguard type III presented better results in the VO2 and aerobic capacity tests (< 0.05). In relation to difficulties experienced when wearing MGs, there were no reports of pain, discomfort, or nausea. However, 100% of athletes affirmed that it was not possible to speak with MG type I, 80% (= 20) with type II, and no athlete found difficulty in speaking when wearing MG type III. Distractions were reported by 35% (= 6) only when athletes wore MG types I and II.


Among the three types evaluated, the customized MG (type III) presented better results in the athletes' physical performance evaluation, even taking into account physical tests performed without the use of mouthguards.

Implant and Prosthodontic Survival Rates with Implant Fixed Complete Dental Prostheses in the Edentulous Mandible after at Least 5 Years: A Systematic Review.

Papaspyridakos, P., Mokti, M., Chen, C.-J., Benic, G. I., Gallucci, G. O. and Chronopoulos, V. (2013), Implant and Prosthodontic Survival Rates with Implant Fixed Complete Dental Prostheses in the Edentulous Mandible after at Least 5 Years: A Systematic Review. Clinical Implant Dentistry and Related Research. doi: 10.1111/cid.12036



The treatment of mandibular edentulism with implant fixed complete dental prostheses (IFCDPs) is a routinely used treatment option.


The study aims to report the implant and prosthodontic survival rates associated with IFCDPs for the edentulous mandible after an observation period of a minimum 5 years.

Materials and Methods

An electronic MEDLINE/PubMED search was conducted to identify randomized controlled clinical trials and prospective studies with IFCDPs for the edentulous mandible. Clinical studies with at least 5-year follow-up were selected. Pooled data were statistically analyzed and cumulative implant- and prosthesis survival rates were calculated by meta-analysis, regression, and chi-square statistics. Implant-related and prosthesis-related factors were identified and their impact on survival rates was assessed.


Seventeen prospective studies, including 501 patients and 2,827 implants, were selected for meta-analysis. The majority of the implants (88.5% of all placed implants) had been placed in the interforaminal area. Cumulative implant survival rates for rough surface ranged from 98.42% (95% confidence interval [CI]: 97.98–98.86) (5 years) to 96.86% (95% CI: 96.00–97.73) (10 years); smooth surface implant survival rates ranged from 98.93% (95% CI: 98.38–99.49) (5 years) to 97.88% (95% CI: 96.78–98.98) (10 years). The prosthodontic survival rates for 1-piece IFCDPs ranged from 98.61% (95% CI: 97.80–99.43) (5 years) to 97.25% (95% CI: 95.66–98.86) (10 years).


Treatment with mandibular IFCDPs yields high implant and prosthodontic survival rates (more than 96% after 10 years). Rough surface implants exhibited cumulative survival rates similar to the smooth surface ones (p  > .05) in the edentulous mandible. The number of supporting implants and the antero-posterior implant distribution had no influence (p  > .05) on the implant survival rate. The prosthetic design and veneering material, the retention type, and the loading protocol (delayed, early, and immediate) had no influence (p > .05) on the prosthodontic survival rates.

Noda, K., Arakawa, H., Maekawa, K., Hara, E. S., Yamazaki, S., Kimura-Ono, A., Sonoyama, W., Minakuchi, H., Matsuka, Y. and Kuboki, T. (2013), Identification of risk factors for fracture of veneering materials and screw loosening of implant-supported fixed partial dentures in partially edentulous cases. Journal of Oral Rehabilitation. doi: 10.1111/joor.12029


This retrospective study identified the risk factors for fracture of veneering materials and screw loosening of implant-supported fixed partial dentures in partially edentulous cases. The study group included a total of 182 patients who were installed 219 suprastructures at the Fixed Prosthodontic Clinic of Okayama University Dental Hospital between February 1990 and March 2005 and were subdivided in two subgroups: 120 patients (149 facing suprastructures) were included in the subgroup to investigate the risk factors of fracture of veneering materials, and 81 patients (92 suprastructures) were included in the subgroup to identify the risk factors of abutment screw loosening. Each patient was followed up from the day of suprastructure installation until March, 2005. A Cox proportional hazards regression model was used to identify the risk factors related to technical complications, and eight factors were regarded as candidate risk factors. Screw retention was the significant risk factor for fracture of veneering materials, whereas connection of suprastructures with natural tooth was the significant risk factor for screw loosening. It was suggested that screw retention was a significant risk factor for the fracture of veneering materials, and connection of suprastructures with natural tooth was a significant risk factor for screw loosening. Future studies, involving dynamic factors (e.g. bruxism) as predictors as well, are more helpful to discuss the risk factor of fracture of veneering materials and screw loosening.

Broadened Definition for Porcelain/Ceramic Materials in the CDT Code Takes Effect January 1, 2013

New classification means 3M™ ESPE™ Lava™ Ultimate Restorative will receive same reimbursement as other porcelain/ceramic materials

ST. PAUL, Minn. – January 11, 2013 – Effective January 1, 2013, 3M™ ESPE™ Lava™ Ultimate Restorative will fall under the CDT Code’s broadened definition of porcelain/ceramic materials thus allowing Lava Ultimate restorative to be classified as a porcelain/ceramic. This classification is solely to aid selection of the appropriate procedure code to achieve uniformity, consistency and specificity in accurately reporting dental treatment.
Lava Ultimate restorative is an innovative new material formulated from a blend of approximately 80 percent nanoceramic particles embedded in a highly-cured resin matrix using a proprietary 3M manufacturing process. When the material was originally launched, the ADA’s CDT Code nomenclature did not yet reflect the advances in material science that Lava Ultimate restorative represents, resulting in challenges with selecting the proper dental procedure code for insurance reimbursement. With the broadened definition for indirect porcelain/ceramic restorations, Lava Ultimate restorative will fall under any CDT code defined for ceramics, allowing for the same rate of reimbursement as other ceramic materials.
"With this change, effective January 1, 2013, we want to ensure that all dentists know about the broadened definition of porcelain/ceramics and what it means for their practice,” said John Stefanick, director of industry & professional relations, 3M ESPE. “This broadened definition of porcelain/ceramics in the CDT Code helps to make the benefits of advanced material science accessible to more patients.”
The insurance reimbursement enabled by the revised definition of porcelain/ceramic materials will make it even easier for dentists to take advantage of Lava Ultimate restorative’s unique functionality, providing restorations that are strong as well as kind to opposing dentition. The restorations can be repaired intraorally if necessary, and are backed by a 10-year warranty from 3M ESPE. With the ability to code Lava Ultimate restorative like other porcelain/ceramic materials for insurance reimbursement, beginning January 1, 2013, even more dentists and patients can experience the outstanding qualities of this material.

Validity, reliability, and reproducibility of linear measurements on digital models obtained from intraoral and cone-beam computed tomography scans of alginate impressions

American Journal of Orthodontics Dentofacial Orthopedics
Volume 143, Issue 1 , Pages 140-147, January 2013


Digital 3-dimensional models are widely used for orthodontic diagnosis. The aim of this study was to assess the validity, reliability, and reproducibility of digital models obtained from the Lava Chairside Oral scanner (3M ESPE, Seefeld, Germany) and cone-beam computed tomography scans of alginate impressions for tooth-width measurements and the Bolton analysis.


A digital model, an intraoral scan, and a plaster model were made for each of 22 subjects. Tooth-width measurements on the digital model and the intraoral scan were compared with those on the corresponding plaster models (gold standard). Intraclass correlation coefficients were calculated to determine the interexaminer reliability of the measurements of each method. The anterior and overall Bolton ratios were calculated for each participant and for each method. The paired t test was used to determine the validity. The scanning time for the intraoral scanner was registered and analyzed.


Tooth-width measurements of each tooth on the digital models and the intraoral scans did not differ significantly from those on the plaster models (P >0.05). The overall and anterior Bolton ratios from the 2 types of digital models differed significantly from the gold standard (P <0 .05=".05" 1.5="1.5" as="as" be="be" clinically="clinically" could="could" decreased="decreased" differences="differences" exceeded="exceeded" however="however" insignificant.="insignificant." intraoral="intraoral" mm="mm" never="never" number="number" of="of" p="p" performed.="performed." regarded="regarded" scanner="scanner" scanning="scanning" scans="scans" significantly="significantly" the="the" this="this" times="times" with="with">


Both intraoral scanning and cone-beam computed tomography scanning of alginate impressions are valid, reliable, and reproducible methods to obtain dental measurements for diagnostic purposes.

Do the smiles of the world's most influential individuals have common parameters?

Orce-Romero, A., Iglesias-Linares, A., Cantillo-Galindo, M., Yañez-Vico, R. M., Mendoza-Mendoza, A. and Solano-Reina, E. (2012), Do the smiles of the world's most influential individuals have common parameters? Journal of Oral Rehabilitation. doi: 10.1111/joor.12027


The aim of this study was to determine – on the basis of the most recent yearly listings – whether there were any common measurable variables associated with the smiles of the world's most influential people. A total of 168 subjects were selected from the lists of Time magazine's 100 most influential people during the period 2006–2010. Smiling frontal view photographs were obtained. Thirty-six variables for each subject were traced and measured using photogrammetric analysis to obtain qualitative and quantitative proportions and measurements. Differences with respect to gender, occupation and year of listing were tested to 95% significance, using the Student's t-test and the Kruskal–Wallis test. The chi-squared test was used for qualitative variables. Irrespective of gender or occupation, the similar quantifiable characteristics of the smiles of the most influential subjects were the following: vertical upper lip proportion, smile width, incisor exposure, buccal corridor ratio, smile symmetry index and intra-dental proportions (P > 0·05). Other qualitative standards were as follows: smile symmetry, the buccal corridors and smile arc, direction of occlusal cant and the degree of deviation between maxillary and facial midlines. Differences were found for gingival display and smile height parameters (P = 0·001). The smiles of the world's most influential people revealed common standards, regardless of occupation or gender, which may play a decisive role in the expressions of influential faces.

Osteonecrosis associated with dental implants in patients undergoing bisphosphonate treatment.

Kwon T-G, Lee C-O, Park J-W, Choi S-Y, Rijal G, Shin H-I. Osteonecrosis associated with dental implants in patients undergoing bisphosphonate treatment. Clin. Oral Impl. Res. 00: 2012; 19.Abstract


Bisphosphonate-related jaw necrosis (BRONJ) associated with dental implants is a rare but continuously reported complication. To verify clinical and pathological characteristics of BRONJ around dental implants, the present study analyzed clinical, radiographic and histopathological findings of these lesions.

Patients and methods

Nineteen patients were diagnosed with osteonecrosis of the jaw associated with dental implants and treated at our institute from 2008 to 2011. The patients' medical history, demographic features, radiographic, and histopathological findings along with information on bisphosphonates (BP) administration were analyzed.


The majority of BRONJ patients associated with dental implants used oral BP for osteoporosis. The patients were divided into two groups: BP initiation before (n = 16) and after (n = 3) implant surgery. Only three patients (15.8%) could be regarded as “implant surgery-triggered” BRONJ. Many patients (n = 9) showed successful osteointegration after fixture installation to an average of 35 months (11–82 months) until the development of osteonecrosis. The histological features of the lesion showed that the necrotic bone with empty lacunae was infiltrated by inflammatory cells and bacterial colonies. Viable osteocytes were also observed in some areas of the bony specimens. Three types of bone destruction pattern were observed: (i) complete necrosis of the bone around the implant (frozen type), (ii) extensive osteolysis around the implant with or without sequestra (osteolytic type), and (iii) sequestration of bone with an implant maintaining direct implant–bone contact (en block sequestration type). These findings could be existed at the same lesions depending on the degree of local bone destruction and the severity of the infection.


These results and those of others suggested that already osseointegrated dental implants can also cause the osteonecrosis around the implant after BP administration. En block sequestration of bone with implant might be one of the characteristics of implant-related BRONJ, which is different from peri-implantitis-induced bone destruction. The possible role of microcracks in this type of bone destruction needs to be examined further.

Periodontitis and atherosclerosis: an observational study

Morado Pinho M, Faria-Almeida R, Azevedo E, Manso MC, MartinsL Periodontitis and atherosclerosis: an observational study. J Periodont Res 2012; doi: 10.1111/jre.12026. © 2012 John Wiley & Sons A/S


Poor oral health has been related with cardiovascular diseases. Specifically, periodontitis has been implicated in the pathogenesis of atherosclerosis. Our aim was to evaluate the relationship between the degree of carotid atherosclerosis and severity of periodontitis in a patient cohort.


Fifty adult patients receiving carotid duplex scans in a cerebral hemodynamics lab were included in the study. Ultrasound protocol included measurement of carotid intima–media thickness (IMT), which is a marker of atherosclerosis, and characterization of any atherosclerotic plaques in the cervical common and internal carotid arteries. Patients were divided into two main groups: the test group had IMT ≥ 1 mm or the presence of any carotid atherosclerotic plaque, and the control group had IMT < 1 mm and absence of atherosclerotic plaques. Periodontal evaluation was performed in all the teeth and characterized according to the clinical attachment level, which between 1 mm and 2 mm was classified as slight, 3 mm and 4 mm as moderate and ≥5 mm as severe.


The control group included 15 (30%), while the test group included 35 (70%) subjects. The most common diagnosis was severe periodontitis (40%); moderate and slight periodontitis were also frequent occurrences (32% and 28%, respectively). In the control group, 53.3% had slight, 33.3% had moderate and 13.3% had severe periodontitis. In the test group, those percentages were respectively 22.2%, 44.4% and 33.3%. Patients with atheroma plaque had the highest percentage of severe periodontitis (70.6%). More severe periodontitis was related to atherosclerosis (P = 0.007).


This study showed an association between periodontitis severity and carotid atherosclerosis, suggesting that periodontal disease might be a risk indicator for atherosclerotic disease.

Oral health-related quality of life in patients with tooth wear. Journal of Oral Rehabilitation

Papagianni, C. E., van der Meulen, M. J., Naeije, M. and Lobbezoo, F. (2012), Oral health-related quality of life in patients with tooth wear. Journal of Oral Rehabilitation. doi: 10.1111/joor.12025


The aim of this study was to investigate the impact of tooth wear (TW) on patients' oral health-related quality of life. A total of 198 participants were included in the study. They belonged to the following four different diagnostic categories: 51 patients with TW, 46 patients with painful temporomandibular disorders (TMD), 43 complete denture wearers and 58 healthy controls. The Dutch version of the Oral Health Impact Profile (OHIP-NL) was used to assess the patients' oral health-related quality of life. The results of the study show that patients with TW have an impaired oral health-related quality of life compared with healthy controls (P < 0·001). Furthermore, the impact of TW and of edentulousness do not differ significantly, while both of these oral conditions seem to have a lower impact on quality of life compared with painful TMD (< 0·05). It was concluded that TW has a negative impact on patients' quality of life. This impact is comparable with that of edentulousness.

Athenahealth to acquire physician favorite mobile app Epocrates for $293M

Epocrates, a top mobile app among physicians, is joining athenahealth , a provider of Electronic Health Records (EHR) software and other online services to doctors and hospitals.
On Monday, athenahealth said it will pay $293 million for the mobile health company, which marks a 22 percent premium over Epocrates’ closing price on Jan. 4.
On a conference call with investors, analysts and journalists, athenahealth CEO and co-founder Jonathan Bush said that the company has long been looking for a way to gain awareness among physicians. In Epocrates, which says it reaches more than 330,000 doctors with its iOS, Android and BlackBerry apps, Bush said, “we believe we have found a breakthrough.”
“We have so much to give doctors,” Bush said. “And so few know who we are.”
Epocrates, which was founded in 1998, initially offered doctors a Palm Pilot-based free drug reference resource. When it transitioned to iOS, the app quickly became a hit, reaching 2,230 downloads per day, Bush said. Athena estimates that 90 percent of doctors are familiar with the app, with about half using it regularly.
Watertown, Mass.-based athenahealth was founded in 1997 and provides hospitals with cloud-based medical billing and patient records services.  Assuming the deal closes, athenahealth will look to Epocrates as a way to extend the company’s name recognition and give doctors a “light” entry point for the service, Bush said.  Beyond using the app for marketing, he said Epocrates will integrate with its electronic records service athenaClinicals so that doctors will be able look up Epocrates drug information straight from Athena’s software, initiate processing the prescription and complete other tasks.
Now, he said, Epocrates is like a “Yelp” for drugs, providing doctors with quick summaries on safety information, interactions and side effects. But, Bush said, in the future, it could be more like an interactive “OpenTable” for drugs, as well as other procedures.

 Richardson, TX, January 2, 2013 – A recent study by faculty and students at the Medical University of South Carolina College of Dental Medicine found clinically acceptable marginal fits — regardless of the quality of the preparation  — with restorations fabricated with the E4D System. There was a statistically significant correlation between the marginal fit and the quality of the preparation, however. Walter Renne, DMD,, reported on the study, which investigated the impact of deviations from the ideal preparation, in The Journal of Prosthetic Dentistry (November 2012)*.

The investigators used preparations placed in three categories (excellent, fair, or poor) and fabricated 75 ceramic crowns with the E4D Dentist system (D4D Technologies, Richardson, TX). They then examined the marginal gap values for each category. The results showed that the presence or absence of common preparation errors was a predictor of the quality of marginal fit.

Citing previous studies, the investigators state that “most authors agree that marginal openings of less than 120 µm are in the range of clinical acceptability with regard to longevity.” They go on to report that the mean marginal gap of the E4D fabricated crowns was significantly better in all categories: 38.5 µm for the excellent preparations, 58.3 µm for the fair preparations, and 90.1 µm for the poor preparations.

“Dr. Renne and his group have done a wonderful job of tying in the quality of the preparation to the ultimate fit of the restoration, as well as confirming the potential quality of chairside restorations produced with the E4D Dentist system,” said Gary Severance, DDS, Chief Marketing Officer of D4D Technologies. “Dental professionals using the E4D System (scan, design, mill) can be assured that they have a system that can produce great fitting restorations for their patients but at the same time know that the fundamentals of quality dentistry still prevail – better preparations lead to better restorations.”

Dr Severance added, “We continue to support the training and continuing education of dental students and professionals through our own educational programs at E4D University as well as with our leading edge E4D Compare adaptive learning technology that enables dental students and faculty to compare students’ preparations to the school’s ideal standard for learning and evaluation. Our initiatives along with those of the dental education community, such as this study that illuminates the importance of preparation design, make us confident that modern technology will empower informed dental professionals to achieve even higher standards of restorative care in the future.”

McGill, DMD, Kaitlyn VanSickle Forshee, Michael R. DeFee, and Anthony S. Mennito, DMD, can be found in The Journal of Prosthetic Dentistry 2012;108:310-315.

ADA Scientific Study Finds Surgical Midlevel Providers Do Not Reduce Overall Rates of Dental Decay

A report published today in the Journal of the American Dental Association details a nearly year-long systematic review of scientific papers about the use of midlevel dental providers to perform such irreversible surgical procedures as restorations and extractions.

In addition to the report, entitled "A systematic review of oral health outcomes produced by dental teams incorporating mid-level providers," JADA also published commentaries by ADA President Dr. Robert Faiella and the study's principal author, Dr. J. Timothy Wright. The report and commentaries are available at the following links:
The analysis shows that the use of mid-level providers who provide surgical treatment does not result in reduced rates of dental caries in the population and that oral health disparities exist regardless of the provider workforce model.

The study's researchers followed the ADA systematic review process, adhering strictly to the Association's criteria for evidence-based dentistry. The workgroup called for "well-designed prospective cohort studies" to better evaluate the impact of midlevel providers on incidence and treatment of dental caries.

Obamacare's effect on your dental practice.

From the Academy of General Denistry

Medical Device Tax Regulations
On Dec. 5, 2012, the U.S. Department of the Treasury and the Internal Revenue Service (IRS) issued final regulations PDF on a new 2.3 percent medical device excise tax. Created by the Patient Protection and Affordable Care Act (PPACA) of 2010, the tax went into effect on Jan. 1, 2013. The IRS will tax manufacturers on the sales of certain devices MS Word, including dental cement and impression material. According to the Organized Dentistry Coalition, this tax will increase the cost of dental care in the U.S. by more than $160 million per year. The Academy of General Dentistry (AGD) continues to work with organized dentistry in attempts to repeal the excise tax, gain an exemption for dental devices, or delay enforcement.
Other Effects of the PPACA
The medical device excise tax isn’t the only way the PPACA could affect your practice. The House Committee on Small Business has released a guide to help small businesses, including dental practices, learn more about PPACA health care provisions that take effect in 2013 PDF and 2014 PDF.
The PPACA in 2013
Get a full timeline of PPACA updates. Updates effective Jan. 1, 2013, include new funding to state Medicaid programs that choose to cover preventive services at little or no cost, and a pilot program of “payment bundling,” which groups services associated with a medical event together for payment.
Upcoming Insurance Coverage Changes
The Centers for Medicare & Medicaid Services has issued an FAQ PDF about state insurance exchanges, which will become fully operational in January 2014. While each state has latitude in structuring its program, this information can help AGD members prepare for what’s to come. AGD members also should familiarize themselves with the proposed Essential Health Benefits guidelines, which outline the benefits insurers must offer in policies sold after 2014.
Dental Practice Compliance Reminders
The American Dental Association (ADA) and U.S. Food and Drug Administration recently updated their radiographic guidelines PDF. Additionally, the ADA’s CDT 2013 Dental Procedure Codes, which went into effect on Jan. 1, 2013, include 35 new codes, 37 revised codes, 12 deleted codes, and seven subcategory changes. The ADA also updated its claim form PDF in July 2012. There do not appear to be any updates yet to the Health Insurance Portability and Accountability Act or Occupational Safety and Health Administration requirements for 2013.

The Tooth Fairy- Malpractice???

Credit: Clark Dunbar/Corbis

In a new article, four London doctors warn of a professional who is committing malpractice and getting away with it: the tooth fairy. They report on an 8-year-old boy who was sent to an allergist because of his epic runny nose. Regular old medical treatment didn't work, so the next step was a CT scan. The scan showed signs of inflammation in the sinuses. But it also revealed something more surprising: a tooth in his left ear canal. It turned out that 3 years before, the boy had woken up "extremely distressed" because the tooth fairy had taken the tooth from under his pillow and jammed it in his ear. His parents thought that was pretty unlikely, although the tooth had indeed gone missing. Two doctors that looked in his ear over the years failed to see anything—but the boy was right, it turned out. An ear, nose, and throat surgeon removed the tooth, the authors report in the often goofy Christmas issue of BMJ. "The patient decided to keep the tooth for posterity rather than taking the risk of attempting a further pecuniary reward," they write. They also point out that there are no standard operating procedures for the tooth fairy, and doctors should be on the lookout for his or her shoddy work.
