Selected AbstractsA continuing education programme for general practitionersEUROPEAN JOURNAL OF DENTAL EDUCATION, Issue 2 2000Status report after 5 years of function In 1992, following newly issued university regulations, the board of the School of Dental Medicine of the University of Geneva decided to establish a structured continuing education course programme for practising dentists in an effort to better meet the school's continuing education mandate. The programme started in January 1994 and was structured so that regular courses would be offered in each discipline of dentistry. The course contents were aimed at satisfying the demands of practising dentists, but it was also established that basic science issues and theoretical concepts should be included. Possible course formats were ,conference', ,hands-on', ,clinical' and ,seminar'. The courses were meant as a form of knowledge transfer from the school to the practising community, but also as a means to generate revenue for research and teaching programmes. Operative aspects were supervised by a small staff which was assisted by computer software designed to handle all procedural steps of course administration, participant registration, accounting, communication. The dentists' responses were rewarding in that attendance was very satisfactory. Closer scrutiny of our data, however, indicates that our impact is still low since at best only 20% of the course-hours required by the Swiss dental association are actually taken. Both course and programme evaluations were satisfactory and are discussed using the Harden and Laidlaw CRISIS criteria. [source] Oral disease experience of older adults seeking oral health servicesGERODONTOLOGY, Issue 2 2010Kavita P. Ahluwalia doi:10.1111/j.1741-2358.2009.00311.x Oral disease experience of older adults seeking oral health services Objective:, The objective of this investigation was to describe the dental disease (dental caries and alveolar bone loss) experience in a sample of community-dwelling older adults who regularly utilize dental services in New York City. Background:, Public financing for dental care directed at older adults in the United States is minimal. Improved preventive methods, primarily the use of fluorides, have resulted in declines in tooth loss, and concomitant increase in risk for dental diseases among older adults. While the oral disease burden in institutionalized elderly and those unable to access services is well-documented, the dental care needs of older adults who access dental services are not well documented. Materials and Methods:, Radiographic and record review were used to determine prevalence of dental caries, alveolar bone loss, frequency of service utilization, and medical status in this cross-sectional investigation of a sample of older adults (N = 200) using dental services at Columbia University College of Dental Medicine. Results:, Only 9% of the sample was completely edentulous, the mean DMFT was 19.9 and mean alveolar bone loss was 3.6 mm. Missing and Decayed Teeth accounted for 57.8% and 6.5% of the total caries burden respectively. Missing Teeth and alveolar bone loss increased with increasing age, but there was no increase in Decayed Teeth. Conclusions:, While access to and utilization of dental services may result in improved tooth retention, older adults who use dental services continue to have dental care needs, especially periodontal care needs. [source] Forensic Dental Training in the Dental School CurriculumJOURNAL OF FORENSIC SCIENCES, Issue 3 2007Daniel C. Stoeckel D.D.S. ABSTRACT: This article reviews the literature regarding forensic education in the dental school curriculum and describes an exercise in forensic identification of victims of a mass casualty. Radiographs were made of dentate human cadavers in the gross anatomy laboratory at the Southern Illinois School of Dental Medicine. The jaws were then removed to provide "wet specimens" for the exercise. Several restorations were performed on the cadaver teeth, after which radiographs of the dissected jaws were made. One author wrote up mock dental records for each of the victims. These records included the first set or "premortem" radiographs. Students participating in the exercise were provided with a plane crash scenario, the dental records of the passengers on the manifest, the dissected jaws, and the second set or "postmortem" radiographs. Students were expected to form three teams. The first two teams evaluated the ante-mortem and postmortem dental records. The third team compared the ante-mortem and postmortem records to arrive at identification. The purpose of the exercise was twofold. It introduced dental students to forensic dentistry and emphasized the need for complete and accurate record keeping in the dental office. Several factors lessened the realism of the exercise and made it difficult to reproduce in the future. These included the uniformity of the dental records and the destruction of cadaver material following the exercise. [source] Orofacial granulomatosis: presentation, pathology and management of 13 casesJOURNAL OF ORAL PATHOLOGY & MEDICINE, Issue 10 2003James J. Sciubba Abstract Background:, Orofacial granulomatosis (OFG) comprises of a group of conditions, all characterized histologically by the presence of granulomatous inflammation. Methods:, This diagnosis may be determined by exclusion from other conditions that may present with similar clinical and histopathologic features. These include Melkersson,Rosenthal syndrome (MRS), Miescher's cheilitis (an oligosymptomatic form of MRS), Crohn's disease, and sarcoidosis. Results:, A great deal of attention has been devoted to the similarity and overlap in clinicopathologic and histomorphologic features of these conditions, suggesting that they may actually represent a spectrum within a single overarching entity. In the review of the 13 cases of OFG retrieved from the files of the Long Island Jewish Medical Center, Department of Dental Medicine, we describe their presentation, clinicopathologic features, and management. These cases comprise examples of MRS (in its oligosymptomatic forms) and Crohn's disease. The similarity, kinship, and overlap between the cases presented are clearly demonstrated. Conclusion:, In addition, based upon our observations and review, we propose the notion that oral manifestations of Crohn's disease may be classified as an oligosymptomatic form of MRS. [source] Students' Perceptions of Prosthodontics in a PBL Hybrid CurriculumJOURNAL OF PROSTHODONTICS, Issue 6 2008Cortino Sukotjo DDS Abstract Purpose: A survey was distributed to the Harvard School of Dental Medicine (HSDM) predoctoral student classes of 2005 and 2006 to assess their perceptions regarding preclinical prosthodontics laboratory exercises. Prosthodontics curriculum clock hours, prosthodontics teaching participation, and plans for specialization were also analyzed. We hypothesized that reduced hours and perceived stress in the prosthodontics curriculum might impact students' choice of specialty at HSDM Materials and Methods: HSDM preclinical prosthodontics clock hours were compared with national means from published data. A survey was distributed to the HSDM classes of 2005 and 2006 (n = 70) at the end of their preclinical prosthodontics laboratory exercises, prior to students seeing their first patient in the clinics. Results: A 100% response rate was achieved. Results from this study show that HSDM preclinical prosthodontics clock hours are on average shorter than other schools. The majority of the students felt stressed during the laboratory exercises, and they felt they did not gain adequate knowledge from the lectures, resulting in low self-esteem (confidence) in treating patients in the clinic. Despite this perception, HSDM students do just as well, if not better, than other students, as judged by external and internal outcome measures. Graduate prosthodontics specialization is still a specialty of choice among the graduates when compared to national data. Conclusions: The shortened preclinical didactic and laboratory exercises in prosthodontics at HSDM affect student anxiety, but not their didactic and clinical performances or their decisions in choosing their graduate program. Problem-based learning (PBL) tutorials help the students to integrate preclinical and clinical knowledge and skills in prosthodontics. [source] Craniofacial skeletal deviations following in utero exposure to the anticonvulsant phenytoin: monotherapy and polytherapyORTHODONTICS & CRANIOFACIAL RESEARCH, Issue 1 2003HI Orup Jr Structured Abstract Authors , Orup Jr HI, Holmes LB, Keith DA, Coull BA. Objective , To identify and quantify the craniofacial effects from prenatal exposure to phenytoin monotherapy and polytherapy using cephalometric, hand-wrist, and panoramic radiographs and to determine if such deviations persist with age. Design , Craniofacial structures of 28 anticonvulsant-exposed individuals were evaluated using 20 landmarks in lateral cephalometric radiographs and 19 landmarks in frontal cephalometric radiographs. Skeletal maturity was assessed using hand-wrist radiographs. Dental maturity and the presence of dental anomalies were evaluated using panoramic radiographs. Eleven individuals were re-evaluated 7 years later, on average, to determine the persistence of any measured deviations. Setting and Sample Population , Department of Growth and Development, Harvard School of Dental Medicine and Massachusetts General Hospital. Patients were recruited from several sources. Outcome Measure , The evaluated dimensions included linear, angular, and proportional measures. Results , The most common deviations were decreased height and length of the maxilla, decreased length of the posterior cranial base, length of the mandible, cranial width and level of the cribriform plate, and a decrease in the Wits Appraisal assessment. The deviations were more significant in the polytherapy-exposed individuals than in the monotherapy-exposed individuals. These deviations, especially in the maxilla, persisted with age as revealed in a re-evaluation of 11 individuals. Conclusion , The craniofacial skeletal findings among individuals exposed in utero to phenytoin monotherapy or phenytoin polytherapy, when considered in aggregate, suggest a mild pattern of maxillary hypoplasia that becomes more pronounced with age. [source] The intermediate effect and the diagnostic accuracy in clinical case recall of students and experts in dental medicineEUROPEAN JOURNAL OF DENTAL EDUCATION, Issue 3 2009J. Eberhard Abstract Introduction:, The extensive knowledge of experts facilitates the solving of domain-specific problems. In general, this is due to the fact that experts recall more detailed information than do novices or even advanced students. However, if physicians of different expertise levels are asked to write down the details of a given case, advanced medical students recall more information than experts. This phenomenon was called the ,intermediate effect' and is considered to be a specific feature of medical expertise. The aim of the here presented study was to examine this observation in the domain of dental medicine. Materials and methods:, Sixty-one students and 20 specialised dentists participated in this study. Three clinical case descriptions were presented and afterwards the participants were told to write down all concrete information they remembered. Finally, they had to come up with a diagnosis. Interrater agreement, diagnostic accuracy and the recall explanation protocols were analysed statistically in comparison to state-of-the-art (canonical) explanations of the clinical cases. Results:, The mean interrater agreement was 96.2 ± 3.37%. It was shown statistically that the more experienced the participants, the more accurate their diagnoses were (P < 0.001). The statistical analysis using the Games-Howell test demonstrated significant more written recall of the 5th-year students compared with 3rd- and 4th-year students and experts (P < 0.05). Conclusion:, The results of this study suggest the existence of the intermediate effect in clinical case recall in dental medicine and thereby corroborate its importance and general applicability for different medical domains. [source] Modulation of platelet activation and initial cytokine release by alloplastic bone substitute materialsCLINICAL ORAL IMPLANTS RESEARCH, Issue 3 2010M. O. Klein Abstract Objectives: Platelet-derived cytokines play a crucial role in tissue regeneration. In regenerative dental medicine, bone substitute materials (BSM) are widely used. However, initial interactions of BSM and platelets are still unknown. The aim of this study was to evaluate the potential of platelet activation and subsequent initial cytokine release by different commercial alloplastic BSM. Material and methods: Eight commercial BSM of different origins and chemical compositions (tricalcium phosphate, hydroxyapatite, bioactive glass: SiO2 and mixtures) were incubated with a platelet concentrate (platelet-rich plasma, PRP) of three healthy volunteers at room temperature for 15 min. Platelet count, aggregation, degranulation (activated surface receptor CD62p) and cytokine release (Platelet-derived growth factor, Vascular endothelial growth factor) into the supernatant were quantified. Highly thrombogenic collagen served as a reference. Results: The investigated PRP samples revealed different activation patterns when incubated with different BSM. In general, SiO2 -containing BSM resulted in high platelet activation and cytokine release. In detail, pure bioactive glass promoted platelet activation most significantly, followed by hybrid BSM containing lower ratios of SiO2. Additionally, we found indications of cytokine retention by BSM of large specific surfaces. Conclusions: Platelet activation as well as consecutive storage and slow release of platelet-derived cytokines are desirable attributes of modern BSM. Within the limits of the study, SiO2 -containing BSM were identified as promising biomaterials. Further investigations on cytokine adsorption and cytokine release kinetics by the respective BSM have to be conducted.
