Assessment Of Apical Transportation and Volume Increase After Glide Path Using Three Different Canal Preparation Systems In-Vitro Study

Introduction: The preparation of root canals is one of the most critical steps of endodontic treatment; anatomical curves in root canals usually consider a confront for the medical practitioner, making a glide path in endodontic treatment became a basic principle to obtain as safe preparation. Objectives: The research aims to assess the effectiveness of the R-Pilot system in creating the glide path with in the simulated S-shaped canal. Material and Methods: A laboratory study to assess the efficiency of three single-file preparation system in preparing 60 transparent resin S-shaped artificial canal, the following preparation systems were used: One Curve, Hyflex EDM, XP Endo Shaper, and manual K-Files and R-Pilot mechanical patency system. Results: No significant difference between the three preparation systems was found in terms of Apical Transportation incidence (P>0.05). Also, there was no difference between the two glide path creation systems used (P>0.05). Evaluating The amount of the removed resin using the two Glide Path systems found a significant difference at all bends between the two groups (P<0.05). Conclusions: There was no difference in Apical Transportation with in all three-preparation systems. The volumetric changes in the removed resin amount have increased when using the R-Pilot system to create the glide path in the middle and the coronal area compared to a manual file.
