Objective: The designation of this study was to compare the knowledge attained by third-year dental students in three clinical exercises in the disciplines of periodontology, conservative dentistry and prosthodontics respectively through video and live demonstrations. Methods: The study was performed on 26 third-year dental students who were randomly segregated into two groups to view a video or live demonstration over three clinical demonstrations. Results: The results were evaluated by calculating the pre-test and posttest scores answered by the pupils of both video and live group before and after viewing either demonstrations respectively. Evaluation and comparison of live and video group showed that the scores obtained by students of the live group were statistically significantly higher than the video group. Therefore, the study resulted in students perceiving better learning outcomes in the live demonstration than the video group as it had the luxury of interaction and clarification with the demonstrator which was lacking in the video counterpart. Conclusion: In our study, the live demonstration had out-performed its video counterpart in all the three sessions. In addition, it must be emphasized that the effectuality of the live demonstration solely lies on the potentiality and the skill of the demonstrator
