Objective: Career choice, one of the most important process in a student's life, has an influence on his/her future life. Hence, it is important to understand student's motives behind choosing a specific career. Hence, the study was designed with an aim to evaluate the factors influencing dental students to choose dentistry as career. Methods: The present cross-sectional survey was conducted on 401 dental students from a dental institute. The data was collected using a structured questionnaire consisting of 13 reasons that possibly influenced students' decision to study dentistry. Data collected was analyzed using SPSS 20 software. Results: Majority of the students participating were female (77.1%). Top four reasons to choose dentistry as a profession were to help poor people (95.5%), to earn prestige and respect (95.0%) followed by self-interest (94.7%) and study of human parts especially teeth (92.8%). Making money was the reason reported by 77.8% of the students. Other reasons reported were inspiration from other dentists (63.3%), did not get admission to medicine (MBBS) course (52.1%), and no doctor in family (51.9%). Family members in medical/dental profession was the least reported reason (36.9%). There were no significant differences among males and females for reported reasons except for one reason, that is, did not get admitted to medicine (MBBS) course (60.9% male and 48.9% female; P = 0.031). Conclusion: Students were mostly influenced by own interest and altruistic nature to opt for dental profession.

Aim: Denture base materials were subjected to cigarette smoke for the purpose of determining their surface roughness. Materials and Methods: Polymethylmethacrylate and flexible denture base materials were used to manufacture 40 specimens for this study (20 for each). Each sample was randomly assigned to one of four groups: control, flexible, and heat-cured denture base material samples. The heat-cured denture material samples were the only ones that had been exposed to cigarette smoke (subgroup III). There was a control group for each group. For the smoke test groups, distilled water was utilised, whereas cigarette smoking was used for the water test groups. Each participant in the trial was exposed to six cigarettes in a specially created smoking area. Surface roughness differences between pre- and post-smoking samples were analysed using a profilometer. The data was analysed using a paired comparison and an independent comparison. Groupings differed significantly in their initial roughness and final roughness, according to results from a paired t-test. Conclusion: Surface harshness of tobacco-smoke-exposed specimens of both the intensity-restored and the adaptive dental replacement base materials was greater.

Aim:To establish an effective combination of drying time and drying method of the tray adhesive so that maximum bond strength can be achieved between impression tray and impression material.Materials and methods: Cylindrical specimens of autopolymerizing resin and addition silicone impression material were made. A total of 150 specimens were tested. They were divided into two groups Dentsply and GC. Each group was further divided into five subgroups:• Drying with compressed air for half the time as recommended by the manufacturer • Drying with air blower for half the time as recommended by the manufacturer • Open air drying as recommended by the manufacturer • Open air drying for 15 minutes • Open air drying for 1 hour The samples were tested for tensile bond strength using the universal testing machine. The results were subjected to statistical analysis.Result: Open air drying as recommended by the manufacturer was better than drying with a blower or compressed air. There was no significant difference between open-air drying for 5 minutes and open-air drying for 15 minutes or 1 hour. Conclusion:Open air drying as recommended by the manufacturer, i.e. 5min, showed good bond strength and drying for more than 5mins does not significantly increase bond strength.Clinical significance: Tray adhesive should not be dried with compressed air or air blower. Tray adhesive should be applied and kept to dry according to the manufacturer's recommended time.
