Clinical evaluation on the preparation of cured root canals with Reciproc and Pathfile rotary instruments

Abstract

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.
