Abstract

Introduction: The main aim of mechanical instrumentation during root canal treatment is to remove the inner layer of dentin to facilities removing all bacteria and smear layer from the canal. New rotary files designs allow more contact to canal walls to improve canal cleaning and shaping.
Aim of study: The goal of this study was to assess the shaping ability of EdgeFile X-7, XP-Endo shaper and TruNatomy rotary files in mesiobuccal root canals of mandibular molars using cone beam computed tomography (CBCT).
Methods: Thirty extracted roots of human mandibular molar teeth of moderate root curvature were selected for this study. The teeth prepared chemo-mechanically using three different systems of Nickel Titanium) Ni-Ti) rotary files. The teeth were divided randomly into three groups (n=10 each) according to the rotary files used in preparation procedure as follows: Group I: EdgeFile X-7, Group II: XP-endo shaper, Group III: TruNatomy. The incidence of canal transportation and canal centering ability by these rotary files before and after instrumentation were assessed using CBCT preoperative and postoperative scanning.
Results: Variation in canal transportation and canal centering ability between groups were compared using Kruskal Wallis test and Freidman test at three mm, six mm, and nine mm levels within all groups. Significance level was set at P value equal 0.05. Showing no significance difference between the three rotary files including canal centering ability and canal transportation.
Conclusion: All the three rotary systems were proved to prepare root canals with minimal canal transportation and good canal centering ability.
