摘要:Studies conducted in Iran indicated dissatisfaction of many students of dentistry in acquiring sufficient skill to carry out therapeutical procedures. The present study was aimed to analyze the effect of short lectures on promoting the knowledge of interns in Endodontic course. In this quasi-experimental study, the knowledge and skill of the experimental group (teaching via short lectures) and control group (traditional teaching method) were compared in Endodontic course. Totally 20 students were included in each experimental and control group. Data were collected by a questionnaire consisting of two sections: demographic information and self-evaluation of the endodontics’ knowledge and skill (30 questions). The means of scores in the pre-test and pot-test in control group were 99±11.2 and 102±11.7, respectively (P=0.13) and the means of scores in experimental group were 100±9.4 and 119±13.7 indicating a significant difference (P<0.05). Short lecture as a simple, inexpensive and less time-consuming method is an efficient method to promote the knowledge in Endodontic course.
