Abstract
Background: Cleaning & Shaping is the most important aspect of successful endodontic treatment. Root canal curvatures pose a challenge to maintain its curvature with achieving adequate cleaning and shaping.
Aim of the work: Our study was conducted to evaluate the shaping ability of three rotary files: Endo plus files. M-Pro files. Protaper Universal; regarding change in canal curvature, canal transportation and centering ratio.
Materials and Methods: Thirty mesiobuccal canals in thirty mesiobuccal roots of mandibular permanent first molars were divided into 3 groups where each group will be instrumented by a file system; Group (A) shaped by Endo Plus Files, Group (B) shaped by M Pro files, Group (C) shaped by Protaper files. Teeth were scanned using CBCT before and after instrumentation, each group with its respective file system, where both scans are superimposed via software and measurements were extracted at 3 vertical levels and analyzed.
Results:
Data : Data was analysed using one-way ANOVA. P ≤ 0.05 was considered as the level of significance.There was no statistically significant difference between the three file file systems, in terms of evaluation of angle of curvature (P = 0.120), Canal Transportation (P = 0.112), Centring Ratio (P = 0.149).
Conclusion: Under the circumstances of this study, it can be concluded that there is no statistical difference between the overall shaping ability of the three file systems regarding the evaluation of change of angle of curvature, canal transportation and centering ability despite the minor difference in performance at different vertical levels.
