Pulpal vitality is important for the tooth to maintain its physiological function and preserve its structure. The aim of this study was to evaluate the clinical and radiographic 6- and 12-month treatment success of calcium hydroxide (CH) and calcium silicate materials in indirect pulp treatment (IPT) and direct pulp capping (DPC) in teeth with deep dentin decay. The study included 143 teeth of patients aged 17-69 years with no systemic disease. The study is grouped under 3 main groups (Dycal, Biodentine, TheraCal PT). Direct pulp capping was applied to 65 teeth and IPT to 66 teeth. All teeth were restored with Universal adhesive system and Universal composite (G-Premio Bond; GC Corp., Tokyo, Japan). In the statistical evaluations of the data obtained, 0.05 was accepted as the level of statistical significance. The general success rate in the IPT group was found to be 95.2% for Biodentine (Septodont, SaintMaur-des-Fossés, France), 91.7% for Dycal (Dentsply/Caulk, International Inc. Milford, USA) and 90.1% for TheraCal PT (Bisco Inc., Schaumburg, USA) at both 6 and 12 months. When the clinical and radiographic success was compared at 6 months and 12 months, no statistically significant difference was determined between the materials (p > 0.05). In the clinical and radiographic evaluations at the end of 6-month follow-up in the DPC group, the success rates were determined to be 96.0% for Biodentine, 81.8% for Dycal and 63.2% for TheraCal PT. At 12 months, these rates were 96.0% for Biodentine, 68.2% for Dycal and 63.2% for TheraCal PT. DPC Biodentine was found to be the most successful material (96.0%). At the end of the 12-month follow-up period, it was considered that the 3 materials (Biodentine, Dycal, TheraCal) can be selected for IPT. In DPC, Biodentine was found to be more successful than both calcium silicate containing resin and CH.

Background: Bruxism may cause increased alveolar bone thickness and density and irregular enlargement of the periodontal space. Aim: This study aimed to evaluate the mandibular bone quality using radio-morphometric indices and Fractal Dimension (FD) analysis in orthopantomography (OPG). Material and Methods: OPGs of 100 patients, 50 bruxers and 50 non-bruxers, were included in this study. Values, such as mental index (MI), panoramic mandibular index (PMI), gonial index (GI), antegonial notch depth (AND), mandibular cortical index (MCI), and antegonial index (AI), were calculated in OPG. Eight bilateral areas of interest (ROI) were selected on ort for FD analysis: ROI 1, mandibular condyle; ROI 2, mandibular ramus; ROI 3, mandibular angulus; and ROI 4, mandibular mental area. Results: MI, PMI, and AND values were higher in bruxers than in the control group (p0.05). As a result of the calculations, the FD values of the left condyle (p=0.02) and left angulus (p=0.03) areas showed a statistically significant difference between individuals with and without bruxer. No statistically significant difference was found in the FD measurements calculated from the ramus and mental areas on the right and left sides (p>0.05). The relationship between FD values and gender in these areas was examined, and no statistically significant difference was found (p<0.05). Conclusion: In dentistry, bruxism can be diagnosed and treated by measuring MI, PMI, and AND values. No difference was found in mandibular cortical bone thickness in bruxers and non-bruxers, according to AI and MCI. The mean GI measured on the right side differed between groups. FD values of the mandibular trabecular bone were affected by bruxism in the right condyle and right angulus areas.

Background: Researches on motivation of students to choose dentistry as a profession has been conducted for many years. Students may choose to become dentists for reasons such as serving, being independent, working with their hands, gaining prestige, and financial security. Purpose: The aim of this study is to evaluate the factors in the career preferences of dental students, their expectations and opinions in the education process. Methods: 1,007 participants who answered the web-based questionnaire were included in this study. Obtained data were analysed using SPSS version 23.0 (Inc., Chicago, IL, USA). The Independent t test was used for intergroup comparisons in the data were normally distributed. Variables in more than two groups were compared using the one-way ANOVA test. Statistical significance was accepted as p<0.05 in all analyses. Results: A total of 1007 dentistry students, 370 (36.7%) male and 637 (63.3%) female, with a mean age of 21.15 ± 1.96 participated in the survey study. 236 (23.4%) of the participants were in the first grade, 236 (23.4%) in the second grade, 192 (19.1%) in the third grade, 261 (25.9%) in the fourth grade, and 82 (8.1%) in the fifth grade. 44% of the participants chose the option 'they want to be medicine or dentistry, but gaining dentistry because of their score in the university entrance exam' as the reason for choosing dentistry. Conclusion: Such studies will be useful for the procedures to be followed in eliminating stress and anxiety in students and in the pre-detection of problems.
