INTRODUCTION: To evaluate the shaping efficiency of WaveOne Gold (WOG; Dentsply Maillefer, Ballaigues, Switzerland) and One Curve (OC; Micro-Mega, Besancon, France) in J-shaped resin blocks.
METHODS: Forty simulated J-shaped root canals with 0.15 mm apical diameters and 2 % taper were divided into two groups (n=20) as follows; WOGG/WOG (25.07) group (glide path was created with WaveOne Gold Glider) and OneG/OC (25.06) (glide path was created with One G) group. The pre- and post-instrumentation images were taken, and the transportation value (TV), centering ability (CA) and the total amount of resin removed (TRR) were calculated by using the superimposition of the images. These parameters calculated with Image J Software Program based on 18 reference points with 1-mm intervals of the canal. The data were analyzed with Kruskal-Wallis and than Dunn's multiple comparison tests. The significance level was set at P ≤.05.
RESULTS: There was no statistically significant difference among OG/OC and WOG/WOGG groups' apical (points 1-3), middle (points 4-6), and coronal (points 7-9) sections in terms of both TV and TRR. The centering ability of the instruments was decreased in the curvature part (middle section) of the canals. While WOG group showed better centering ability at points 6- 7, OC group exhibited better result at point 2.
DISCUSSION AND CONCLUSION: Within the limits of this study, WaveOne Gold and One Curve, which are single-file systems, could be used safely in J-shaped root canals with their glide path files. Further investigations on the extracted tooth and clinical conditions are needed.
