Exploring an integrated virtual simulation application of dental cavity preparation for training hand dexterity among stomatology undergraduates

目的探索Simodont虚拟仿真系统和进阶性仿真备牙教具模拟备洞实践训练在口腔医学专业学生手灵活性训练中的应用效果。方法2021年9月至2022年9月,选取空军军医大学2020级五年制口腔医学专业44名学生为研究对象,通过虚拟仿真系统和仿真备牙教具2种仿真实践训练提升其手灵活性。2种仿真实践训练分别进行2次操作,记录每次操作评分;统计学生训练前后的奥康纳镊子灵活性测试用时。采用配对t检验比较2次操作评分及灵活性测试的前后差异。采用问卷调查了解学生对训练的主观感受。结果学生虚拟仿真系统2次操作评分分别为(8.27±2.84)分和(8.89±2.90)分,仿真备牙教具评分分别为(8.29±2.45)分和(8.96±2.48)分,差异均有统计学意义(均P<0.05)。学生训练前后奥康纳镊子灵活性测试用时分别为(316.80±40.64)秒和(295.08±39.27)秒,差异具有统计学意义(P<0.05)。问卷调查结果显示,所有学生均认为2种仿真实践训练方法都具有较好的操作灵敏度,且2种方法各有侧重,可以实现优势互补。结论采用2种仿真实践训练方法进行教学,有助于提升五年制口腔医学专业学生的手灵活性,并获得了良好的满意度,为临床前训练学生手部技能提供了参考和借鉴。

Objective To explore an integrated virtual simulation application of dental cavity preparation trainings for improving hand dexterity among stomatology undergraduates.Methods 44 sophomores majored in stomatology in the Fourth Military Medical University were selected to use 2 kinds of simulated trainings including Simodont Dental Trainer Equipment(SDTE)and Advanced Simulation Dental Cavity Preparation Training Aid(ASDCPTA)from 2021 to 2022.The course was delivered in two training sessions.And all students′operation scores in each session were recorded,respectively.Meanwhile,the timespans of the O′Connor Tweezer Dexterity Test(OTDT)were separately recorded before and after training.And the questionnaire evaluated subjective training feeling of students.Paired t tests were used to analyze the differences in operation scores and paired OTDT results.Results The SDTE scores of the two training sessions were 8.27±2.84 and 8.89±2.90,respectively.The ASDCPTA of the two training sessions scores were 8.29±2.45 and 8.96±2.48,respectively.The timespans of OTDT were separately(316.80±40.64)seconds and(295.08±39.27)seconds.The training effectiveness was improved significantly(P<0.05).Questionnaire surveys showed that the sensitivities of two training applications were recognized by all students.and two methods could complement each other.Conclusions The application of two practical integrated virtual simulation training can effectively improve the hand dexterity of undergraduates,who have high level of satisfaction to these methods,which provided meaningful references for preclinical training of hand skills.
