摘　　要：目的使用Simodont虚拟仿真口腔培训系统对不同年级口腔学生手部灵巧度进行训练并对结果进行定量评估,探讨该系统的应用价值。方法汕头大学医学院口腔医学系2015至2018级共118名学生进行统一培训后,每位学生给予5个不同的手部灵巧度练习模块进行练习,每个模块有3个难度进阶,每个模块要求30 min内完成。系统自动记录每个学生的操作成绩,包括规定磨除量、底壁和侧壁磨除偏移量及误磨量,均以体积百分比为单位;同时评估操作时间(以秒为单位)、操作过程中口腔用手机位移和口镜位移(以米为单位)。应用SPSS 25.0软件进行统计分析。结果对于规定磨除量、底壁和侧壁磨除偏移量及误磨量,系统评估结果显示:已经经过专业课学习和仿真头模等临床前培训的学生(四年级学生)和未进入专业课学习、未经过培训的学生(一到三年级学生)之间差异具有统计学意义(P<0.001)。对于规定磨除量的完成情况,5个练习模块均能体现年级间差异性并具有统计学意义(P<0.001)。结论Simodont虚拟仿真口腔培训系统中圈形模块、隧道模块、甜甜圈模块和十字交叉模块具有对不同层次口腔医学学生手部灵巧度能力评估的敏感性,立体边缘模块对手部灵巧度能力评估的敏感性则需要通过进一步的评估。Simodont虚拟仿真口腔培训系统对手部灵巧度训练结果(如规定磨除量、底壁和侧壁偏移情况等)可进行定量评估,对口腔临床前教育的评价具有重要意义。Objective To explore the application of the Simodont dental trainer in preclinical manual dexterity training for dental students of different grades,and to discuss its effect by quantitatively evaluating their practice results.Methods The evaluation was conducted among 118 students in the Department of Stomatology,Shantou University Medical College from Batch 2015 to Batch 2018.Each student had five different manual dexterity modules for training.Each module had three levels of difficulty and was required to be completed in 30 minutes.The assessment index included Target,Leeway Bottom and Sides,Container Bottom and Sides,which was provided by the Simodont dental trainer.The operating time(in seconds),the displacement of the dental hand pieces and the dental mirrors(in meters)were simultaneously recorded.SPSS 25.0 was used for statistical analysis.Results For the index Target,Leeway Bottom and Sides,Container Bottom and Sides,the results showed that there was a statistical difference between students who passed pre-clinical training and who did not take the professional course(P<0.001).For the index Target,differences were showed among students from different grades in all modules(P<0.001).Conclusion The circle module,channel module,hollow-circle module and cross-module in the Simodont dental trainer have sensitivity to discriminate the manual dexterity of different levels of dental students.The further assessment of the discrimination of the manual dexterity is required for assume-block module.The Simodont dental trainer can quantitatively measure the manual dexterity of dental students,which is important for the quantitative evaluation of dental preclinical education.
