【摘要】 目的:应用计算机辅助根管形态测量系统评价学生的树脂透明牙模型根管预备效果,检验该测量系统的实用性和有效性。方法:2组学生按3种方式预备透明牙6(第1组:透预备;第2组:盲预备→后透预备)。透明牙在根管预备前、后做正、侧位的定位透扫,应用计算机辅助根管形态测量系统评价根管预备效果。SPSS10.0统计软件进行统计学分析。结果:将计算机辅助根管形态测量系统应用于根管治疗的临床前教学,可以清楚地反映根管预备前后的形态变化,突显各种根管预备缺陷。透预备组根管预备缺陷的发生率较低,后透预备组根管扩大量最大。结论:计算机辅助根管形态测量系统和透明牙的联合应用可定量反映根管预备效果,提高根管治疗的学习效果。

【Abstract】 Objective:To test the validity of the computer-added measure system in pre-clinical practice training of root canal treatment with resin transparent tooth models.Methods:Two groups of students prepared resin transparent tooth models in three ways.Transparent root canal preparation was conducted by the first group, blind root canal preparation and blind followed by transparent preparation were conducted by the second group. Resin transparent tooth models were scanned frontally and laterally before and after the preparation. The computer-added measure system was used to evaluate the effect of instrumentation. The data was analyzed by SPSS 10.0 software.Results:It was helpful to understand the change of root canal shape and the problems in instrumentation by using the computer-added measure system with resin transparent tooth models in pre-clinical practice training. The transparent preparation resulted in lower frequency of the preparation defects(P<0.05). The blind followed by transparent preparation resulted in the biggest enlargement of the root canals(P<0.05).Conclusion:Using the computer-added measure system with resin transparent tooth models can make trainees understand the preparation effect quantitatively, and improve the learning effect.
