Brief 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.

Primary Outcomes (2)
Proficiency in Crown Preparation after instructional Videos and Live Demonstrations i
Proficiency in Crown Preparation: Assessed by a standardized scoring chart evaluating key areas such as preparation axis, axial reduction, anatomic reduction, occlusal convergence, occlusal reduction depth, morphology, quality of axial/occlusal line angles, finish line location, form, continuity, and surface texture. Each area is scored to give a total proficiency score out of 20. Measurements will be taken immediately following the intervention period."

students perception about the demonstration techniques of the three groups
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. Specifically, the questions addressed stress levels during preparation, the duration of preclinical training, the effectiveness of lectures and training, and readiness for clinical practice. Responses were recorded using a Likert scale ranging from 1 to 5, where 1 represented "strongly disagree" and 5 represented "strongly agree".

Interventions
Participants in Group A received access to a specially prepared pre-recorded instructional video detailing the step-by-step process of porcelain-fused-to-metal tooth preparation for molars.
Participants in Group B were provided with live demonstrations of the same procedure conducted by the same experienced Prosthodontist to ensure consistency in teaching quality and technique
Group C received a dual approach, combining instructional video guidance with live demonstrations.
