Effect of educational intervention on computer-aided-design and computer-aided-manufacturing technology to preclinical dental students.

Introduction: This study evaluated the effectiveness of a video presentation instruction compared to the prevailing traditional lecture provided in the preclinical classroom when introducing computer-aided design/computer-aided manufacturing (CAD/CAM) technology.

Materials And Methods: This study was conducted as a controlled educational trial (single-blind) on 120 first-year dental students. Students were assigned to two learning groups: the control (n = 60, traditional lecture) and the intervention (n = 60, video presentation).
