Simodont系统辅助照明条件对口腔临床技能训练的影响

目的探讨Simodont虚拟仿真系统中虚拟涡轮机机头的辅助光照对实际操作的影响,为口腔临床技能训练提供指导。 方法选取四川大学华西口腔医学院口腔医学专业本科生56人为研究对象,按随机数表法随机分为两组,实验组（虚拟仿真牙科训练机的涡轮机头的辅助灯处于打开状态）和对照组（虚拟仿真牙科训练机的涡轮机头的辅助灯处于关闭状态）的学生分别使用Simodont虚拟仿真系统在不同辅助光照情况下进行练习和考核,并在临床冷光灯条件下使用玻璃板模拟临床操作,采用t检验对比分析两组的得分。并通过问卷调查了解学生的使用体验。 结果不同辅助光照条件下,Simodont虚拟训练机操作总分（t = 1.342,P = 0.181）和临床冷光灯条件下玻璃板的操作结果（t = -0.585,P = 0.561）差异均无统计学意义;但Simodont总分构成项中"Leeway sides（洞缘偏差）"项有光组学生分数为5.38 ± 4.69,大于无光组分数（4.32 ± 2.92）,差异有统计学意义（t = 2.252,P = 0.025）。 结论尚不能认为Simodont系统在有辅助灯的条件下可以影响医学生的培训效果,但在有辅助照明的情况下操作可能更容易误碰到规定区域边界的侧方。问卷结果显示,Simodont虚拟仿真系统是一种值得推广的教学模式。

Effect of auxiliary illumination of Simodont dental trainer on oral clinical skill training

ObjectiveTo investigate the effect of the auxiliary illumination of virtual turbine head on operation in Simodont Dental Trainer and to help instruct oral clinical skill training. MethodsFifty-six undergraduates majored in stomatology in West China School of Stomatology were randomly distributed into two groups according to the method of random number table. Students in the experimental group (with auxiliary illumination of virtual turbine head on operation in Simodont Dental Trainer) and the control group (without auxiliary illumination of virtual turbine head on operation in Simodont Dental Trainer) were practiced and tested under different auxiliary light conditions through Simodont, and glass plates were used to simulate clinical operations under clinical cold light. The scores of the two groups were compared by t-test. Students′ perception of use experience was analyzed through questionnaires. ResultsThere was no significant difference in the total score of Simodont (t = 1.342, P = 0.181) and the result of glass plate (t = -0.585, P = 0.561) , but the score of Leeway sides in the light group was higher than that in the non-light group (t = 2.252, P = 0.025) . ConclusionsIt was not yet believed that the auxiliary illumination of Simodont Dental Trainer can affect the training effect of dental students, but it may be easier to mistakenly touch the boundary of the prescribed area when operating with auxiliary illumination. The result of the questionnaire showed that the Simodont Dental Trainer was of high recommendation in the dental preclinical teaching.
