Background:
A competent dental undergraduate at the preclinical level will ensure a confident transition into clinics and quality treatment for patients. Cavity preparation of a tooth is one of the key competencies in dentistry. A preclinical training module was introduced to enhance the skill training and improve students' learning.
Aim:
This study aims to develop and implement a preclinical operative dentistry module to enhance Class-II cavity preparation training.
Methodology:
Feedback was taken from the 3rd year undergraduate batch regarding the preclinical operative dentistry training. Based on the feedback, a training module was developed and implemented for Class-II cavity preparation for 2nd year dental students. The three-stage intervention included a preparatory intervention with a Prebrief PowerPoint presentation, followed by a live demonstration of the Class-II cavity preparation and access to a video demonstration. In the third stage, formative assessments were conducted with the help of an assessment rubric. At the end, student and faculty perceptions were gathered using a feedback survey.
Results:
Most students (98%) were satisfied with the training. All the faculty strongly agreed that the module should be part of future training. Video demonstration and rubric-based assessments were testified by 93% of students as the most helpful element of the module. Major themes after thematic analysis were a better understanding of the procedure, enhanced visualization, the ability to identify areas for improvement, and boosted confidence for final exams.
Conclusions:
The preclinical training module successfully met the needs of the participating undergraduate students. Video demonstration proved a beneficial digital learning resource.
