目的：本研究旨在评估使用数字培训系统进行烤瓷牙冠制备的临床前培训与传统培训方法相比的有效性。材料和方法：将 66 名参与的四年级牙科本科生样本随机分配到两组中的一组进行烤瓷冠制备：实验组使用在线同行评审系统（OPRS）和实时牙科培训和评估系统（RDTES）的数字方法进行培训；实验组使用在线同行评审系统（OPRS）和实时牙科培训和评估系统（RDTES）的数字方法进行培训；对照组使用传统方法进行培训，并有讲师演示和评估。训练结束后，两组均进行左上中切牙烤瓷冠制备，并由经验丰富的导师根据预先设定的评估标准进行盲法评分。使用 Student t 检验或 Wilcoxon 符号秩检验对两者的结果进行比较。显着性水平为 P < .05。实验组学生回答了关于数字化培训系统的利弊的问卷。结果：数字化组的考核结果15个项目中，有5个项目明显优于传统组。对实验组学生的问卷调查结果表明，96.97%的学生同意或强烈同意使用数字化培训系统比传统方法更能提高实践能力。实践成绩总分与问卷分值呈显着正相关。结论：OPRS和RDTES的数字化培训系统可能是牙科临床前临床前课程中传统培训方法的良好替代方案。
Purpose: This study aimed to evaluate the effectiveness of preclinical training on ceramic crown preparation using digital training system compared with traditional training method.Materials and methods: A sample of 66 participating fourth-year undergraduate dental students were randomly assigned to one of two groups for ceramic crown preparation: experimental group as trained using digital method with Online Peer-Review System (OPRS) and Real-time Dental Training and Evaluation System (RDTES); control group as trained using traditional method with instructor demonstration and evaluation. At the completion of training periods, both groups performed the preparation of ceramic crown of upper left central incisor, which were blindly scored by the experienced instructors under the pre-defined assessment criteria. The results of both were compared using Student's t-test or Wilcoxon signed rank test. The level of significance was P < .05. The questionnaires regarding the benefits or drawbacks of digital training system were answered by the students of experimental group.Results: Five of 15 items in the assessment outcome of the digital group were significantly better than the traditional group. The questionnaire results from the students of the experimental group indicated 96.97% of the students agreed or strongly agreed that using digital training system could better improve the practical ability than traditional method. The total scores of practical results were significantly positively correlated with the points of the questionnaires.Conclusion: The digital training system with OPRS and RDTES might be a good alternative to the traditional training method in the preclinical course of dental practice.
