摘要/Abstract

摘要： 目的：评价联合使用Pathfile和Reciproc预备弯曲根管的临床效果。方法：选择2012年12月—2013年1月期间就诊需进行根管治疗的88颗患牙273个根管，随机分为3组。A组联合使用Pathfile和Reciproc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组均采用连续波热牙胶充填。记录每个单根管的预备时间，器械分离数、术后疼痛例数，X线评价根管预备效果。采用SPSS 17.0 软件包对数据进行χ²检验。结果：A组预备时间短，无器械分离，无根管偏移，无台阶形成，能维持根管的弯曲度和走向，预备后疼痛率少，充填效果好。与B组和C组相比，均有显著差异(P<0.01)。结论：Pathfile和Reciproc联合应用于弯曲根管预备快速、安全、成形效果好，并发症发生率低，值得临床推广。

Abstract: PURPOSE: To evaluate the effect of cured molar root canal preparation using Reciproc and Pathfile rotary instruments. METHODS: From December 2012 to January 2013, 88 teeth with 273 root canals were randomly divided into three groups. In group A, root canals were prepared with Reciproc and Pathfile. In group B, root canals were prepared with ProTaper and Pathfile. In group C, root canals were prepared with rotary ProTaper. All root canals were filled with continuous wave condensation. The operating time for each root canal, the incidence of instrument separation and postoperative pain were recorded. The efficiency of reparation was analyzed with radiograph. The data was analyzed with SPSS17.0 software package. RESULTS: In group A, the mean operation time was significantly shorter without instrument separation, transportation and ledge. The technique could keep the curvature and flow of curved canals. Postoperative pain was significantly lower, and appropriate filling of root canals was significantly higher than in other groups (P<0.01). CONCLUSIONS: Curved root canal preparation with Reciproc and Pathfile is less time consuming and more convenient with fewer side effects. It is an efficient instrumentation for curved canals and can be used widely.
