CAVITY, CARIES
For caries removal task on a mannequin, artificial teeth by Frasaco® (Frasaco dental model, ANKA-4 V CER, Tettnang, Germany) in the phantom head (similar to the phantom head used in VRHS) were used. The task involved caries removal mirroring the task on VRHS (2mm depth and 2mm width) in a #36 tooth with caries outlined on the occlusal surface of the tooth. Once students completed their tasks within the allocated time (40 min), feedback by calibrated, experienced supervisors were provided (blinded to study vs control group), and the first cavity preparation in the CSE was graded digitally on Blackboard (Blackboard Inc, US) The assessment rubric used a three-point scale (satisfactory, borderline, unsatisfactory) to evaluate cavity outline, depth, and efficacy of caries removal. The rubric was shared with the students on blackboard before the commencement of training and assessments.
