Selected AbstractsTwo-year follow-up of fractured anterior teeth restored with direct composite resin: report of three casesDENTAL TRAUMATOLOGY, Issue 5 2008Emre Ozel Fractures of maxillar central incisors including enamel and dentin were diagnosed. Beveling with diamond bur was performed in all four cases. Dentin was cleaned with tungsten carbid bur. The teeth were etched with 37% phosphoric acid, restored with an adhesive system and microhybrid composite. Finishing and polishing procedures were performed by discs (Sof-Lex) and burs. Restorations were found successful according to modified United States Public Health Service (USPHS) criteria after 2 years in terms of retention, color match, marginal discoloration, secondary caries, marginal adaptation, and surface texture. [source] Clinical and SEM evaluation of all-ceramic chair-side CAD/CAM-generated partial crownsEUROPEAN JOURNAL OF ORAL SCIENCES, Issue 2 2003Andreas Bindl The effect of hardware and software on the quality of Cerec all-ceramic partial crowns was investigated in this cross-sectional study. Partial crowns (n = 818) had been adhesively placed in 496 patients between 1993 and 1997 using Cerec 1 and Cerec 2 units (groups 1 and 2) as well as Cerec 2 with wall-spacing software (group 3). From each group, 25 randomly selected partial crowns were evaluated using modified United States Public Health Service (USPHS) criteria. Of these, 12 were randomly selected in each group, replicas taken and examined in a scanning electron microscope for marginal interfacial width and for continuous margin adaptation. Interfacial width of group 1 (308 ± 95 µm) was significantly larger than those of groups 2 (243 ± 48 µm) and 3 (207 ± 63 µm). Continuous margin adaptation at the tooth,luting composite and luting composite,restoration interfaces showed only minor differences in groups 1 (94.5 ± 8% and 95.5 ± 2%), 2 (98.1 ± 1% and 97.5 ± 1.4%) and 3 (96.8 ± 3% and 96.8 ± 2%). Pooled clinical rating was excellent or good at 97% for all groups, indicating acceptable restoration quality except for one breakage in group 1. [source] Defining a National Health Research and Practice Agenda for Older Adults with Intellectual DisabilitiesJOURNAL OF POLICY AND PRACTICE IN INTELLECTUAL DISABILITIES, Issue 1 2004Philip W. Davidson Abstract With the increasing number of adults with intellectual disabilities (ID) surviving into old age governments, provider agencies, and practitioners are recognizing the insufficiencies of available information related to the interaction of the aging process with lifelong disability, the incidence of disease and secondary conditions with advancing age, and the means to provide quality medical and health care. These insufficiencies were noted by a World Health Organization report that identified a need for more research on the health of older adults with IDs and reports from two meetings held by United States Public Health Service and the United States Surgeon General that examined health disparities among adults with ID. This paper reports the process and results of the Tampa Scientific Conference on Intellectual Disabilities, Aging, and Health, a meeting held in 2002 specifically to examine health issues germane to older adults with ID. The meeting produced a long-term research agenda for determining more effective physical and mental health outcomes for aging and older persons with ID and recommendations for aging-related medical and health surveillance practices that would improve the overall health status of adults with ID. [source] Marginal Adaptation of Cerec 3 CAD/CAM Composite Crowns Using Two Different Finish Line Preparation DesignsJOURNAL OF PROSTHODONTICS, Issue 3 2006Jaber Hussain Akbar DDS Purpose: The purpose of this study was to compare marginal discrepancies of Cerec 3 CAD/CAM composite crowns, fabricated on human prepared teeth with two different finish line designs, chamfer and shoulder. Materials and Methods: Sixteen human molar teeth were used to prepare full crowns. Eight teeth were prepared with a 1-mm-wide chamfer finish line and the other eight with a 1.2- to 1.5-mm circumferential shoulder. Cerec 3 crowns were fabricated from optical impressions using Paradigm MZ100 composite polymer. Marginal adaptation was evaluated in two ways: (1) using modified United States Public Health Service (USPHS) criteria to evaluate eight preselected sites on each crown margin, and (2) using scanning electron microscopy (SEM) to measure marginal gaps on all four axial walls with 15 measurements on each wall (60 measurements per crown). An evaluation of the number of acceptable crowns, determined by having all measured sites per tooth with margin gap size less than 100 ,m, as a function of finish line design was also conducted. Results: In both chamfer and shoulder groups, there were only two crowns (out of eight) with clinically acceptable ratings for all eight measurement sites according to USPHS criteria. Fisher's chi-square analysis showed that there was no statistically significant difference in marginal adaptability as a function of finish line design ( p > 0.05). With SEM imaging, overall mean marginal gaps for the chamfer group were 65.9 ± 38.7 ,m (range 35.0 to 130.0 ,m), and for the shoulder group were 46.0 ± 9.2 ,m (range 26.3 to 55.6 ,m); this difference was not found to be statistically significant ( p > 0.05). While crown assessment based on mean marginal discrepancy measurements indicated that both the chamfer and shoulder groups were considered clinically acceptable (<100 ,m); crown acceptability based on all measurement sites being less than 100 ,m indicated that in the chamfer and shoulder groups there were four and three acceptable crowns out of eight, respectively. The Fisher's chi-square test indicated no statistically significant difference between the groups ( p > 0.05). An agreement rate of 81.2% was calculated between the two evaluation methods, modified USPHS criteria and SEM measurements. Conclusions: Based on mean marginal discrepancy measurements, the typical marginal assessment technique, Cerec 3 Paradigm MZ100 crown restorations appear to have acceptable marginal adaptability (mean discrepancies <100 ,m). Thus, the evidence from this investigation would suggest that the finish line preparation design had no effect on marginal adaptation for Cerec 3 composite crowns. [source] One-year clinical evaluation of a two-step self-etch adhesive with and without additional enamel etching technique in cervical lesionsAUSTRALIAN DENTAL JOURNAL, Issue 2 2010E Ozel Abstract Background:, The aim of this study was to determine the clinical performance of a two-step self-etch adhesive with and without additional enamel etching technique to advanced non-carious cervical sclerotic lesions. Methods:, Twenty-two patients (mean age = 51.5) having at least two pairs of non-carious cervical erosion/attrition/abfraction lesions with incisal or occlusal margins in enamel and gingival margins in dentine/cementum were included in the study. The two-step self-etch adhesive (AdheSE; Ivoclar-Vivadent) was either applied following the self-etch approach on both enamel and dentine (AdheSE non-etch), or a similar application including additional acid-etching of the enamel cavity margins with 37% phosphoric acid (AdheSE etch). Resin composite Point 4 was used for all 104 restorations. Restorations were evaluated at baseline and at one year according to the modified United States Public Health Service (USPHS) criteria. Data were analysed by using McNemar's test (p <0.05). Results:, There were no significant differences in the marginal adaptation both at the cervical and enamel margins between AdheSE non-etch and AdheSE etch groups (p >0.05). At one year, marginal discolouration was evident in the AdheSE non-etch group but it was not statistically significant from the AdheSE etch group (p = 0.12). Postoperative sensitivity was 5% at baseline and reduced to 2% at one year. Conclusions:, At one year, the two-step self-etch adhesive with and without additional enamel etching technique showed excellent clinical results to advanced non-carious cervical sclerotic lesions.
