Simodont虚拟仿真系统在龋病学实验课教学中的应用

摘要

目的：研究在龋病学实验课中运用Simodont虚拟仿真系统的教学效果。方法将Simodont系统运用于口腔医学五年制学生的龋病学实验课教学。步骤如下：①编写《Simodont操作手册》《龋病临床技能考核手册》和《龋病学实验教学问卷》。②通过随堂测验的方式要求学生在规定时间内回答《龋病学实验教学问卷》中龋病临床知识的相关问题，对学生龋病临床知识的掌握情况进行评价。③指导学生在规定时间内分别使用Simodont数字化虚拟仿真培训系统和Kavo仿真头模系统进行临床训练，并预备改良型II类洞和改良型V类洞。由实验课教师根据《龋病临床技能考核手册》中的标准进行评分。④运用《龋病学实验教学问卷》，要求学生在规定时间内完成对Simodont数字化虚拟仿真培训系统评价。结果经过Simodont系统培训后学生预备改良型II类和V类龋洞的评分较培训前有明显提升（P＜0．05）。但Simodont系统培训后，学生预备改良型II类和V类龋洞的评分仍较使用Kavo仿真头模系统培训的评分低（P＜0．05）。教学问卷结果表明：Simodont数字化虚拟仿真培训系统具有节省培训时间、安全、可重复性好等优点，可弥补Kavo仿真头模的一些不足。学生对联合应用Simodont系统和Kavo仿真头模系统具有高度认同。结论在龋病学实验课中单独使用Simodont系统有助于提升学生的操作技能，但其教学效果较Kavo仿真头模系统弱。%Objective To study the outcomes of Simodont Virtual Simulation System in cariology experiment teaching.Methods We applied Simodont System in cariology experiment teaching for five-year students of stomatology.Four steps were followed:① We prepared Simodont Operating Manual, Caries Clinical Skills Assessment Handbook and Cariology Experiment Teaching Questionnaire.②In in-class quiz the students were asked to answer caries-related questions in Cariology Experiment Teaching Questionnaire,and their clinical knowledge was evaluated.③ We guided the students to use Simodont Virtual Simulation Training System and Kavo Head Phantom System within a specified time,and then prepare modified Class II and Class V caries cavities.A cariology experiment teacher scored the operation results according to the criteria of Caries Clinical Skills Assessment Handbook.④ The students were asked to complete Cariology Experiment Teaching Questionnaire to evaluate the training system.Results The operation scores of students in preparing caries class II and V cavities were significantly improved (P<0.05 )after Simodont training,but the training results were not as good as those of Kavo Head Phantom Training System (P<0.05).The teaching questionnaire results showed that Simodont Digitized Virtual Simulation Training System is time-saving,safe and repeatable,which may make up for some deficiencies of Kavo head phantom. Students showed high acceptance for combined application of Simodont system and Kavo Head Phantom System in cariology operation training.Conclusion In cariology experiment class,Simodont system is effective in improving students'clinical skills,but its training effect is not as good as that of Kavo Head Phantom System.
