Abstract

Purpose: To evaluate the canal transportation and centering ability of the WaveOne Gold® (WOG) system with a mechanical glide path carried out in continuous rotation and with a reciprocating motion using Cone Beam Computed Tomography (CBCT). Methods: 54 extracted mandibular incisors with canal curvature <35° were divided into 3 groups (n= 18). Each group was randomly assigned to manual K and H-files (MF/WOG), Proglider (PG/ WOG) of WaveOne Gold Glider® (WOGG/WOG) for glide path preparation. Each canal was then shaped with WOG to working length. The teeth were scanned before and after instrumentation and CBCT images were superimposed by using the Romexis software. Canal transportation and centering ratio were then calculated at 3 levels (4 mm, 7 mm and 11 mm from the apical end). Data were analyzed using 2 tests: Kruskal-Wallis test and Mann-Whitney test (P<0.05). Results: At 7 mm (middle section) the groups PG/WOG and WOGG/WOG showed significantly less transportation and better centering ratio compared to the group (MF/WOG). Conclusion: The mechanical glide path improved shaping ability of WaveOne Gold® and led to less canal transportation. Although no difference was observed between continuous rotation and reciprocating motion glide path, the reciprocating motion represents a reliable approach for glide path preparation.
