Background: Teachers have conventionally been using different teaching methods to educate dental students by blackboard and slide projectors. It is very important for any dental teacher to meet the educational need of the students regarding their knowledge, attitude and skills. Audiovisual (AV) aids help the conventional teaching methods like a Blackboard (BB), overhead projector (OHP), power point presentation (PPT), audiotapes and film loops. The present study was an attempt to assess the student’s perceptions for the use of AV aids in teaching dental subjects. Materials and Methods: A questionnaire based analytical cross-sectional study was carried out among 500 dental students attending lectures in a regional dental college, Bhimavaram, A.P. Students were made familiar with all the dental subjects and exposed to different AV aids like blackboard, OHP and PPT, used for lecture delivery. Various parameters were included in the questionnaire forms to evaluate the student’s perception for AV aids during teaching dental subjects. The data collected was analyzed using Statistical Package for Social Sciences (SPSS) version 20. Results: The questionnaire provided was found to be reliable with Cronbach’s α value of 0.774. 70.6% of students showed interest in taking notes rather than taking handouts [29.4%]. Students reported that all the dental subjects were effectively taught using PPT followed by BB except for Biochemistry and Pharmacology. The perception of diagrams, flowcharts and note taking was best accepted with a PPT followed by BB, lectures were clear, understandable, well-organized and students were stimulated by PPT for further reading. Conclusion: Our study showed that lectures delivered using PPT were more appreciated by the students followed by BB and narration. OHP was the least preferred method by the dental students.
