摘　　要：目的:研究PREPassistant系统在洞形预备评估中应用的可行性。方法:使用PREPassistant系统对学生预备的65个盒状洞形的侧壁和底壁的角度以及洞形深度进行分析评估。结果:学生预备洞形的洞底基本与牙合平面平行;颊舌向固位形较理想,而在近中、远中方向洞形敞开,固位不佳;洞形深度预备不足的情况较多。结论:PREPassistant系统可以较准确客观反映学生洞形预备的情况,结合传统的教学评估方法,有助于实验课教学水平的提高。AIM： To study the effect of PREPassistant system in the training of caviy preparation.METHODS： Sixty-five box-shaped preparations on typodont teeth were prepared by students.The depths and angles of the preparations were evaluated by PREPassistant system.RESULTS： On the whole,the pulpal walls of students′ preparations paralleled to occlusal surface.On the facial-lingual plane,the convergent wall angulations benefited the retention of preparations.But on the mesial-distal plane,the angulations were divergent.There were insufficient reduction depth in most of students′ preparations.CONCLUSIONS： Combined with traditional visual evaluation,the kavo PREPassistant is a powerful tool in preclinical teaching.
