Abstract
Objective:To assess the differences of preparations in pre⁃clinical dental students before and after the comprehensive tooth preparation training through the PrepCheck 2�0 ( CEREC® ) software of the computer aided design ( CAD) . Methods:Forty junior dental students were randomly selected for participating the 14 days preclinical tooth prepara⁃tion training which contained the studies of a 3D video of tooth preparation,the application of the CAD system(SW 4�4,Prep⁃Check 2�0). Each student was required to prepare 2 teeth before and after training,respectively. The rates of overlap between the experimental tooth preparations and the master mold,including the shoulder and morphology,were calculated by the Prep⁃Check 2�0 software. The differences were compared between the rates of overlap in tooth preparation before and after training, respectively. Results:There was significant improvement after training in the rates of overlap between the prepared shoulder and the pre⁃defined shoulder,experimental preparation and the master preparation(P<0�05). Conclusion:The courses of pre⁃clini⁃cal comprehensive training can effectively improve the student’ s tooth preparation skill,and the quality of tooth preparations.关键词
