EDTA輔助C型先鋒銼疏通鈣化根管的臨床效果觀察
[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.
