Background: Effective management of an emergency situation in the dental office is ultimately the dentist’s responsibility. Lack of good training and the inability to cope with these medical emergencies can lead to tragic consequences and sometimes legal action. Aims: Dental students have little understanding about medical emergencies, and there is very little in-depth data about the importance they place on this important area, i.e., fundamental to their professional training. A survey of 50 students from a dental college was carried out to evaluate the amount of awareness about the emergency drugs of the dental office. Materials and methods: The survey was conducted for the students of S Nijalingappa Dental College and Hospital, Gulbarga, India, who were undergoing 1-year mandatory internship. The number of students involved in this pilot survey was 50. A questionnaire was designed to obtain relevant information on the list of emergency drugs a dentist is supposed to know. The responses to the questionnaire so obtained were analyzed. Results: The results showed that undergraduate dental students perceive a need for more intensive education in medical emergency drugs as more than 70% of students were not aware of most of the emergency drugs of choice required in situations like hypotension, anaphylactic shock, allergic reaction, etc.

Purpose In spite of best available impression materials and advanced techniques, we still come across imperfect fit of a dental prosthesis. Selection of impression material is based on the results from the research carried out, hence the accuracy of this research needs to be at the topmost priority, hence a proper research model and methodology has to be followed. The purpose of this paper was to highlight on technique and the device made to meet these requirements. Method An in vitro study was done to evaluate the linear dimensional accuracy of commercially available polyvinyl siloxanes of varying viscosities using different impression techniques. A standardized experimental procedure is required to provide identical direction of insertion and removal of the trays that contained the impression material. An impression tray positioning device has been designed and machined in an attempt to meet these requirements. Conclusion It was found that putty-wash 2-step techniques with controlled bulk in stock tray found to be as accurate as multiple-mix technique, utilizing heavy viscosity and low viscosity combination in a custom tray and single-mix technique, utilizing medium viscosity in a custom tray.
