Our aim was to evaluate haptic virtual reality (VR) simulation with repetitive training as a tool in teaching caries removal (CR) and periodontal pocket probing (PPP) skills. For the CR simulation, multilayered virtual models composed of tooth substance, caries, and pulp were developed. Seven students completed three training sessions each, which were scored based on the volume of the cut region, the number of instances of handpiece overload, and total cutting time. For the PPP task, we developed a virtual periodontal disease model and 26 students received training in measuring pocket depth. Pocket probing force was measured and proficiency was evaluated. In the CR task, scores for the second and third training sessions were significantly higher than for the first training session. We likewise obtained effective repetitive training results for the PPP task. Our simulator was effective at teaching hand skills for both tasks within short-term evaluation.
我们的目的是评估将重复训练的触觉虚拟现实（VR）模拟作为一种工具，用于教授龋齿去除（CR）和牙周袋探查（PPP）技能。对于CR模拟，开发了由牙质、龋齿和牙髓组成的多层虚拟模型。七名学生每人完成了三次训练课程，根据切割区域的体积、机头过载的次数和总切割时间进行评分。对于PPP任务，我们开发了一个虚拟牙周疾病模型，26名学生接受了测量牙周袋深度的训练。测量了牙周袋探查力并评估了熟练程度。在CR任务中，第二次和第三次训练课程的分数显著高于第一次训练课程。我们同样在PPP任务中获得了有效的重复训练结果。在短期评估中，我们的模拟器在教授这两项任务的手部技能方面是有效的。
