【摘要】：目的：观察EDTA辅助C型先锋锉疏通钙化根管的临床效果，探讨疏通钙化根管的有效方法，提高根管治疗成功率。方法：在2012年3月-2013年10月就诊于银川市口腔医院牙体科，因各种原因需行根管治疗的患牙中，选取符合纳入标准的患牙50例，钙化根管62个，采用C型先锋锉（C-Pilot files）与EDTA凝胶（乙二胺四乙酸）一次或多次联合应用，对钙化根管进行疏通，K锉逐步后退法预备根管，侧方加压充填技术完成根管充填。结果：62个钙化根管中，成功疏通41个，成功率为66.13％；术中2例发生根管偏移，，未发生根管壁侧穿及器械分离。结论：C型先锋锉与EDTA一次或多次联合应用，能够有效提高钙化根管的疏通率，值得在临床推广应用。
[Abstract]:Objective: to observe the clinical effect of EDTA assisted C-type vanguard file in the treatment of calcified root canal, to explore the effective method of dredge calcified root canal, and to improve the success rate of root canal therapy. Methods: from March 2012 to October 2013, 50 teeth with calcified root canal were selected from the dental department of Yinchuan Stomatology Hospital, which needed root canal treatment for various reasons. C-type pioneer file (C-Pilot files) and EDTA gel (ethylenediamine tetraacetic acid) were used in one or more times to dredge the calcified root canal. K file was used to prepare the root canal and the lateral pressure filling technique was used to complete the root canal filling. Results: of the 62 calcified root canals, 41 were successfully dredged, and the success rate was 66.13.The root canal deviation occurred in 2 cases, and no lateral perforation of root canal wall and separation of instruments occurred. Conclusion: the combination of C type avant-garde file and EDTA can effectively improve the rate of ossification of calcified root canal, and it is worth popularizing in clinic.
