To investigate the accuracy of cone beam CT (CBCT) images obtained with and without artefact reduction (AR) in detecting simulated buccal peri-implant and buccal periodontal defects. 42 implants inserted into edentulous mandibles, and 38 teeth present in dry mandibles were used. Simulated buccal peri-implant defects (n = 22) and buccal periodontal defects (n = 22) were prepared. 20 implants and 18 teeth without simulated defects were the control group. Images of the mandibles were obtained using a Planmeca ProMax(®) 3D Max CBCT unit (Planmeca Oy, Helsinki, Finland). Image reconstructions were prepared without and with low, medium and high AR modes. Images were viewed randomly by six observers twice for the presence of defects. Kappa coefficient was calculated. F2_LD_F1 design for non-parametric analysis of longitudinal data was used. Area under curves (AUCs) were calculated for each observer. Significance level was taken as α = 0.05. Intraobserver kappa ranged from 0.140 to 0.792 for peri-implant and from 0.189 to 1.0 for periodontal defects. All factors were statistically significant (p < 0.001), except for image mode and implant brand. Pairwise interactions were found between periodontal defects and peri-implant defects (p < 0.001), observers (p < 0.001), observer and image mode (p < 0.001), defect model and observer (p < 0.001) and defect model, image mode and observer (p = 0.04). AUC values ranged from 0.39 to 0.52 for peri-implant and from 0.45 to 0.71 for periodontal defects. Higher AUC values were found for periodontal defects than for peri-implant defects. Buccal peri-implant defects were more difficult to detect than buccal periodontal defects. No difference was found among CBCT images obtained with and without AR modes.

Health care professionals including dentists can experience increased professional burnout. The aim of the study was to evaluate the association between depressive symptoms and burnout among Turkish dentists. This study was conducted among a Turkish dentist sample in Ankara (Turkey) between February 2015 and August 2015. From a total of 500 dentists, 337 were included. A self-structured questionnaire, Maslach Burnout Inventory (MBI), and Beck Depression Inventory (BDI) were completed by the participants. The Student t test or analysis of variance was used to compare the variables. A total of 337 dentists (162 female dentists; mean age of participants 36 ± 4.45 years) participated in this study. Age, sex, professional status, years in profession, sector, and number of patients seen/d were factors affecting level of burnout (P < 0.05); 29% of the participants showed burnout and 22.2% showed depressive symptoms. Participants showed increase in emotional exhaustion (38%), increase in depersonalization (22%), and decrease in personal accomplishment (12%). The mean score of BDI significantly correlated with those of the MBI subscales (P < 0.05). All items of BDI except weight loss, irritability, and loss of appetite significantly correlated with MBI subscores (P < 0.05). Dentists may face burnout and depressive symptoms during their professional life. Increased burnout level can give an idea on depressive symptoms, and may provide an opportunity to identify depression earlier. Creating and raising awareness about burnout are important to avoid and prevent depression among dentists. Further longitudinal studies analyzing the effects of interdisciplinary client-centered self-management programs for dentists on depressive symptoms and burnout must be planned.

To study the use of blood culture bottles for culturing vitreous specimens in acute-onset postoperative infectious endophthalmitis cases. Forty-eight eyes of 48 patients with mean age of 66.4 +/- 14.7 years with postoperative endophthalmitis that occurred within 6 weeks after ocular surgery, presenting from June 2001 to January 2005, were retrospectively studied. Vitreous fluid specimens of these patients were cultured in blood culture bottles. The measured outcome is the yield of positive culture. Vitreous specimens yielded positive in 34 of 48 (70.8%) eyes with blood culture bottles. The most common organism isolated was Staphylococcus epidermidis in 17.6% (6/34) of cases. The direct inoculation of vitreous specimens into the blood culture bottles is easy to perform, with a high yield positive rate (70.8%). It may be an alternative to conventional culture media for culturing vitreous specimen in infectious endophthalmitis especially in clinics or hospitals that are unable to have adequate microbiology laboratory facilities.

To evaluate occlusal splint type differences in patients with bruxism. Seventeen controls and 51 patients were divided into three subgroups, each assigned to use a different occlusal splint (hard, ...
