摘　　要：目的:评价联合使用Pathfile和Protaper预备磨牙弯曲根管的临床效果。方法:选择需进行根管治疗的磨牙102颗,376个根管,随机分为2组。根管预备过程中,A组联合使用Pathfile和Protaper镍钛锉,B组仅使用Protaper镍钛锉。2组均采用连续波热牙胶充填。比较2组在根管预备时间、器械分离率、根尖偏移率、根管恰填率以及预备后疼痛发生率等方面的差异。采用SPSS 16.0对数据进行x2检验。结果:在根管预备时间方面A组与B组差异无统计学意义;A组在器械分离率、根尖偏移率、根管恰填率及预备后疼痛发生率等方面均较B组为优,且差异具有统计学意义(P<0.05)。结论:Pathfile和Protaper联合使用预备磨牙弯曲根管具有安全、快速、根尖偏移率低、充填效果好、术后疼痛少等特点。Objective：To evaluate the clinical effect of the use of Pathfile and Protaper nickel-titanium instruments for preparation of curved root canal of molars. Method：A total of 102 teeth,376 root canals from patients that need root canal treatment were randomly divided into two groups. The root canals were prepared with Pathfile and Protaper nickel-tita-nium instruments in group A and only Protaper nickel-titanium instruments in group B. All root canals of both groups were filled by continuous wave of condensation technique. The root canal preparation time,the ratios of equipment separation,api-cal transportation,adequate filling,and post-operative pain of both groups were compared between the two groups. Result：There were no significant difference of the preparation time between group A and group B;the ratios of equipment separa-tion,apical transportation and post-operation pain in group A were significantly less than that in the group B （P ＆lt;0.05）. Conclusion：Combined Application of Pathfile and Protaper nickel-titanium instruments for preparation of curved root canal of molars are safe, fast, have low apical transportation, better filling effect, and less post-operative pain.
