The purpose of this study was to assess novice student perception of haptic-based manual dexterity training. The short-term impact of haptic training in the early phase of preclinical operative dentistry education was also investigated.
Dental students performed a class II amalgam and a class III resin tooth preparation in a typodont model at baseline. The experimental group performed exercises on the manual dexterity module of the IDEA™ software using a haptic device. The exercises required removing the maximum amount of three-dimensional geometric shapes within a predetermined width and depth. Tooth preparations were repeated 2 weeks later. A questionnaire survey was given to assess the subjective evaluation of the haptic simulation exercise.
Tooth preparations were scored regarding external outline, internal form, and integrity of adjacent tooth. Improvement of overall tooth preparation scores post-haptic use was not statistically significant compared to controls (P > 0.05). However, students found the game-feature of the haptic device made the learning experience more fun and interesting.
The haptic exercises with the manual dexterity module software were not superior in improving the dexterity of students for tooth cavity preparations in short-term. Benefits of ease of use and fun learning experience can be further investigated in future studies.
本研究旨在评估新手学生对基于触觉的手动灵巧性训练的认知。同时还调查了触觉训练在临床前口腔手术教育早期阶段的短期影响。
牙科学生在基线时在牙模型上进行II类汞合金和III类树脂牙齿预备。实验组使用触觉设备在IDEA™软件的手动灵巧性模块上进行练习。这些练习要求在预定的宽度和深度内去除最大量的三维几何形状。两周后重复牙齿预备。进行问卷调查以评估对触觉模拟练习的主观评价。
根据外部轮廓、内部形态和邻牙完整性对牙齿预备进行评分。与对照组相比，使用触觉后整体牙齿预备分数的提高在统计学上不显著（P>0.05）。然而，学生们发现触觉设备的游戏功能使学习体验更加有趣。
使用手动灵巧性模块软件进行的触觉练习在短期内提高学生制备牙腔的灵巧性方面并不优越。在未来的研究中可以进一步研究其易用性和有趣学习体验的益处。
