目的：针对临床钙化阻塞根管预备中是否采用EDTA凝胶辅助C型先锋锉和手用ProTaper镍钛锉进行根管预备的临床效果比较，以其提高口腔根管治疗质量。方法制定严格筛选标准，选取根管细小钙化患牙50颗，钙化根管136个，随机分为两组，实验组采用EDTA凝胶辅助C型先锋锉和手用ProTaper镍钛锉预备根管70个；对照组不使用EDTA凝胶，只用C型先锋锉加手用ProTaper镍钛锉预备根管66个，根据X线片和临床指标等检查比较两组根管预备效果。结果实验组70个钙化根管有61个根管扩通，达到根管预备要求，成功率87.14%；对照组66个钙化根管有34个根管扩通，成功率51.52%，对比两者之间有显著差异。结论在临床钙化阻塞根管的机械预备中应用EDTA凝胶辅助，可极大提高钙化阻塞根管的疏通率，提高口腔根管治疗质量，有效保留患牙。

Objective To compare clinical effect of root canal preparation by ProTaper nickel titanium and EDTA gel preparation, to improve the quality of root canal therapy. Methods The strict screening criteria, selection of fine root canal calcification 50 teeth, calcified root canal 136, were randomly divided into two groups, the experimental group with EDTA gel assisted C pioneer file and hand ProTaper nickel titanium file in root canal preparation70;control group without the use of EDTA gel, only C pioneer file hand ProTaper nickel titanium file in root canal preparation 66, according to the X-ray and clinical examination were compared between the two groups of root canal preparation effect. Results 70 calcified root canals of 61 root canal expansion, to prepare for the root canal, the success rate was 87.14%;the control group 66 calcified root canals of 34 root canal expansion, the success rate was 51.52%, there was a significant difference between the two comparison. Conclusion The application of EDTA gel root canal blocking auxiliary mechanical preparation in clinical calcification, can greatly improve the calcified root canal occlusion of the dredging rate, improve the quality of root canal therapy, the effective teeth.
