Abstract:
Objective:To develop a standardized training model incorporating feedback from a digital assessment tool and to evaluate whether the model provides effective training in tooth preparation.Methods:The study was based on the training data of 53 trainees enrolled between February and June 2018 from multiple institutions in China. The trainees were trained in a standardized training unit on the preparation of right maxillary mesial incisors (11 #) for metal ceramic crowns. Three sessions of practice-assessment-feedback before examination were performed in one day. A digital assessment system was used to obtain total and component scores for the preparation as indicators of observation. The scores of three practice sessions and examination were subjected to analysis of variance. Results:The mean total scores before training, after the first training session, after the second training session, after the third training session, and in the examination were (60.53±12.73), (60.12±12.98), (71.25±13.70), (70.70±11.84), and (69.67±12.85), respectively; the overall difference was statistically significant ( F=19.06, P<0.001). Compared to the total scores before training and after the first training session, the total scores after the second and third training sessions and in the examination were significantly increased ( P<0.001, P<0.001). The score deductions for cutting amount and shoulder were similar, with overall significant differences (score deductions for cutting amount, F=16.20, P<0.001; score deductions for shoulder, F=1.45, P=0.032). Compared to before training and after the first training session, the second and third training sessions and the examination showed significant decreases in score deductions for cutting amount and shoulder ( P<0.001, P=0.048). Conclusions:The feedback-based standardized training process established on a digital evaluation system can rapidly enhance the skills of dentists in tooth preparation through immediate and effective feedback and targeted improvements. The training process enables an independent practice mode and optimizes teaching outcomes.
