Background and Aim: Maintaining the original central canal path during cleaning and shaping of the root canal system plays an important role in the success of endodontic treatment. This study sought to compare canal transportation and centering ability of WaveOne and SafeSider rotary files using cone-beam computed tomography (CBCT).
Materials and Methods: This in-vitro, experimental study was conducted on 40 mesiobuccal canals of extracted human mandibular first molars with 20° to 40° of curvature. The teeth were randomly divided into two groups (n=20) and mounted in putty. Next, preoperative CBCT scans were obtained. Root canals were prepared using primary file of WaveOne in group A and SafeSider system up to file #25/0.04 taper in group B. Postoperative CBCT scans were taken and cross-sectional images at 1, 3, and 7 mm distances from the anatomic apex were compared. Data were analyzed using t-test and two-way analysis of variance (ANOVA).
Results: WaveOne was significantly superior to SafeSider regarding the canal centering ability and caused significantly less canal transportation (P<0.001). The canal centering ability of both systems was higher at the coronal and middle thirds of the root compared to the apical region (P<0.05).
Conclusion: WaveOne, in contrast to SafeSider, has optimal canal centering ability and less transportation in curved root canals.
