Summary

finding the optimal balance between traditional live demonstrations and instructional videos remains a subject of ongoing discussion in dental education. Moreover, integrating a hybrid model that combines the strengths of both methods may offer a comprehensive approach to crown preparation training. Therefore, this study aims to address this ongoing discussion by investigating the relative effectiveness of traditional live demonstrations, instructional videos, and a hybrid model that merges both approaches. Through an evaluation of dental students' satisfaction and performance with video tutorials and hands-on demonstrations, this research endeavors to shed light on how different instructional methods influence knowledge acquisition within the practical environment.

Detailed description

A randomized controlled single-blind trial was conducted at the Department of Prosthodontics, Altamash Institute of Dental Medicine for a duration of 12 months from 12th Jan' 2023 till 11th Jan' 2024. Prior approval was obtained from the Ethical Review Committee of Altamash Institute of Dental Medicine (AIDM/ERC/01/2023/02). written consent was obtained from all participants, A simple random sampling technique was used for the recruitment of participants. . a total of ninety-six final-year BDS students were enrolled in the study. Before allocation, all participants attended a comprehensive lecture on crown preparation principles delivered via a PowerPoint presentation. Following the lecture, participants were randomly assigned to one of three groups: Group A (instructional video), Group B (live demonstrations), or Group C (hybrid) Participants in Group A will view an instructional video, group B will attend live demonstrations. Participants in Group C received a dual approach, combining instructional video guidance with live demonstrations. Before the intervention, all participants across the three groups underwent a pretest consisting of five questions. These questions were designed to gauge participants' readiness and perceptions regarding crown preparation training. Responses were recorded using a Likert scale ranging from 1 to 5, where 1 represented "strongly disagree" and 5 represented "strongly agree". Following the lecture and demonstrations, participants were provided with an assessment questionnaire comprising six questions aimed at evaluating their comprehension and knowledge regarding porcelain-fused-to-metal tooth preparation.
