Aim: The study attempted to evaluate the shaping ability of One Curve single file in comparison to ProTaper Next multiple-file NiTi in terms of transportation and centering ability in curved mesiobuccal canals of human extracted mandibular molars using CBCT scanning.

Materials and Methods: Mesiobuccal canals of thirty extracted mandibular first and second molars with the angle of curvature ranging 20-45 ͦ (according to Schneider) were randomly allocated into two equal groups; One Curve (OC) and ProTaper Next (PTN) groups. Pre- and post-instrumentation CBCT imaging was performed to assess the centering ability and canal transportation of the tested instruments at 3, 5 and 8 mm from the apex.

Results: Regarding the results of canal transportation and centering ability, there was no statistically significant difference mesiodistally among the two groups at 3, 5, and 8mm (P > 0.05).

Conclusion: The canal transportation values of the two tested rotary systems are considered acceptable. Both of One Curve and ProTaper Next systems were not able to achieve perfect centering ability during root canal preparation.
