复合树脂充填术虚拟仿真实训系统在口腔专业本科教学中的应用研究

目的 本研究旨在评估复合树脂充填术虚拟仿真实训系统对口腔医学专业本科生知识获取、技能发展和整体学习体验的影响。方法 2019级口腔医学专业41名本科生在进入实习前分为两组进行临床前培训：试验组使用复合树脂充填术虚拟仿真实训系统；对照组观看复合树脂充填术操作视频。对比两组学生临床实习时首次复合树脂充填操作的考核情况和教学反馈。采用SPSS 20.0进行t检验和卡方检验。结果 试验组学生在反复使用复合树脂充填术虚拟仿真实训系统训练后能掌握该复合树脂充填术的操作要点，均获得较高的分数（平均达91.77分），平均用时10.39 min。在实习阶段，试验组和对照组学生在器械选择（85.71% vs.40.00%）、粘接剂涂布（76.19% vs.45.00%）和分层充填（100.00% vs.75.00%）操作正确率方面差异有统计学意义（P<0.05）。所有学生一致认可该虚拟仿真系统的使用价值，并表示愿意在实习前使用该系统进行岗前练习，19名学生（90.48%）对此虚拟仿真实训系统的学习体验表示满意。结论 复合树脂充填术虚拟仿真实训系统可以使学生在临床实习前提升对复合树脂充填术的理解和熟练度，有助于更好地过渡至实习阶段。

Application of virtual training system for composite resin filling technique in undergraduate stomatology teaching

Objective To assess the influence of a virtual simulation-based training system for composite resin filling on the knowledge acquisition, skill development, and overall learning experience of undergraduate stomatology students.Methods Forty-one undergraduate students of grade 2019 majoring in stomatology were divided into two groups for preclinical training before their internships: the experimental group used a virtual training system for composite resin filling, while the control group watched instructional videos of the procedure. The two groups were compared for their first performance in composite resin filling during the internships and teaching feedback. The t-test and chi-square test were conducted for data analysis using SPSS 20.0.Results After repeatedly using the virtual training system for composite resin filling, the students in the experimental group were able to master the key operational points of the procedure, all achieving high scores (an average of 91.77 points) with an average time of 10.39 minutes. During the internship phase, the experimental group and control group showed significant differences in the accuracy rates of instrument selection (85.71% vs. 40.00%), adhesive applying (76.19% vs. 45.00%), and layered filling (100.00% vs. 75.00%; all P<0.05). All the students unanimously recognized the value of the virtual simulation system and expressed their willingness to use it for preclinical training before internships. Nineteen students (90.48%) were satisfied with the learning experience with the virtual simulation training system.Conclusions The virtual simulation training system for composite resin filling can improve students'' understanding and proficiency levels of the technique before clinical internships, facilitating a smoother transition to the internship phase.
