The Evaluation of the Effect of Educational Videos and Time of its Application on Practical Learning of Dental Anatomy and Morphology

Computer technology has been started since 1960 and the presentation of electronic education in Dental Schools has been initiated since 1980-1990. Considering the importance of practical course in dental morphology and presence of learning problem issues and lack of information in Iranian society، this research was conducted on dental students. This study was conducted on 66 fourth semester dental students consisting of 3 groups of 22 each. Three practical courses (carving of maxillary canines and first premolar and mandibular second premolar)، were selected. Each of the topics was taught in two ways: traditional (control) and film (before and after the traditional teaching). At the end of the semester، final assessment and test scores of the practical Dental morphology course were analyzed by generalized estimating equations (GEE) and factors related to learning practical morphology lessons were analyzed using Wald test. According to the results of the Generalized Estimating Equations، no statistically significant differences among the groups in learning practical lessons of dental morphology were observed in the intervention and control groups (P=0. 15 and P=0. 3). Wald test showed that the number of children، the economic situation and interest to the dental morphology department was different between the groups (P=0. 025، P=0. 021، P=0. 04). Other variables examined did not have statistically singificant relationship with the learning of the teeth morphology (P>0. 05). Finally، among the three techniques implemented traditional method gained the highest score compared to the two other techniques. Traditional mothels seem to be the most suitable technique as compared to the other 2 mothels.
