The Use of Video Demonstration in Teaching Restorative Dentistry
Objectives: This study determined the effectiveness of video demonstration as a method of instruction in teaching restorative dentistry.
Methods: The pre-test, post-test control and experimental group design was utilized in this study. The study involved all the 30 preclinical Dentistry students enrolled in the course Restorative Dentistry 1 for the First Semester, Academic Year 2019-2020 at the University of Baguio School of Dentistry. The level of performance of students were recorded before any lecture and intervention made (Pre-test), after which utilization of traditional face-to-face lecture and live demonstration were implemented to the control group while face-to-face lecture and video demonstration were implemented to the experimental group. Both groups performed a practical examination and were assessed in relation to their performance on their cavity preparation (Post-test). The scores of the experimental and control groups were compared using t-test for independent samples.
Results: The pre-test level of performance of students in the control group and experimental group were both poor. This indicates that they cannot execute proper cavity preparation for Class II and that they are in need of thorough knowledge about the different features as to outline form, resistance form, retention form, and finishing of the cavity walls. The post-test level of performance of students in the control group was poor and the experimental group was fair. The experimental group got a higher mean difference than the control group. This means that considering the mean differences between the pre-test and post-test of the two groups, the experimental group performed better.
Conclusions: The use of video demonstration as a means of instruction in cavity preparation in restorative dentistry is effective in enhancing students' performance.
