【摘要】：目的评价联合使用Pathfile和Mtwo预备弯曲根管的临床效果。方法选择2013年12月至2014年2月期间因牙髓炎或根尖周炎需进行根管治疗的90颗患牙,313个根管,随机分为3组。A组联合使用Pathfile和Mtwo镍钛锉进行根管预备,B组联合使用Pathfile和ProTaper进行根管预备,C组单独使用ProTaper进行根管预备。3组均采用热牙胶连续波垂直加压充填。记录3组在根管预备时间、器械分离数、根尖偏移和充填效果方面的差异。结果 A组预备时间最短,为(6.01±1.12)min,未见器械分离和根尖偏移,恰填率高。与B组及C组比较,差异均有统计学意义(均P0.05)。结论 Pathfile和Mtwo联合应用于预备弯曲根管快速安全,根管充填效果佳,适合临床推广应用。
[Abstract]:Objective to evaluate the clinical effects of combined use of Pathfile and Mtwo for the preparation of curved root canals. Methods 90 teeth and 313 root canals which needed root canal therapy for pulpitis or periapical periodontitis from December 2013 to February 2014 were randomly divided into 3 groups of.A groups combined with Pathfile and Mtwo nickel titanium files for root canal preparation, and group B combined with Pathfile and Pro. Taper was used for root canal preparation, group C was used separately for root canal preparation in group.3, and group.3 was filled with hot tooth glue continuous wave. The difference between the 3 groups in the preparation time of root canal, the number of apparatus, the excursion of root tip and the effect of filling were recorded. Results the preparation time of the A group was the shortest, which was (6.01 + 1.12) min, and no instrument separation and root excursion was found. Compared with group B and group C, the difference was statistically significant (P0.05). Conclusion the combined application of Pathfile and Mtwo to the preparatory curved root canal is fast and safe, and the root canal filling effect is good. It is suitable for clinical application.
