Comparative evaluation of canal transportation and Centring ability of Protaper (NT), Reciproc and Oneshape file systems using cone beam computed tomography- An- In vitro study
Journal Title: INTERNATIONAL JOURNAL OF CURRENT RESEARCH - Year 2016, Vol 8, Issue 8
Abstract
The purpose of this in-vitro study was to compare the canal transportation and centring ability of Protaper Next (NT), Reciproc and OneShape (OS) file system. Materials and Methods: Thirty human extracted mandibular molars having non-calcified roots with mature apices, minimum length of 18 mm and an apical curvature of 15-30 degrees (according to Schneider’s method), were selected for this study. Samples were randomly divided into three groups (n=30) and canal preparation with Protaper NT, Reciproc and OS was performed according to manufacturer’s instruction. Pre- and post-instrumentation cone-beam computed tomography (CBCT) images were captured and the extent of canal transportation and centering ability of the files were calculated, using the NNT Viewer software and Photoshop CS5, at levels of 3, 6, and 9 mm from the apex. The One-way analysis of variance (ANOVA) with Tukey’s honestly significant difference (HSD) were used to analyze the statistical significance between the three groups. Conclusions: The canal preparation with Reciproc file system showed lesser transportation and better centering ability than Protaper NT and One Shape file system.
