ObjectiveThis study aimed to evaluate the effectiveness of video-based learning, live demonstrations, and brochures in teaching scaling and root planning (SRP) skills to third-year dental students in a preclinical periodontal education setting.MethodNinety third-year dental students who had not previously received theoretical or practical training in SRP were included in this randomized study. The students were equally assigned to three instructional groups: brochure, video, and live demonstration. To evaluate the initial effectiveness of these methods, all participants first performed SRP on standardized typodont models coated with simulated calculus, created using a consistent application of black nail polish. Each student performed 10 strokes per surface using identical instruments to ensure standardization. Pre- and post-procedure images of the models were taken for objective assessment. The extent of calculus removal was quantified through pixel area measurements using image analysis software. Following the practical sessions, a validated 10-item Likert-scale questionnaire was administered to assess students' perceptions of the instructional methods, focusing on clarity, engagement, satisfaction, and preferences for future learning.ResultsSignificant improvements in the quality of scaling and root planing were observed in all three groups after education. Video and live demonstration methods were significantly more effective than the brochure method. However, there were no significant differences between video and live demonstration groups. Student feedback showed that both the video and live demonstration methods received significantly higher scores than the brochure method; however, there was no significant difference between the video and live demonstration methods.ConclusionBoth video-based learning and live demonstrations are equally effective and superior to brochures for teaching critical periodontal skills. These results suggest that interactive teaching methods should be prioritized in dental education to enhance student outcomes and better prepare them for clinical practice.
