Context: The purpose of this study was to evaluate and compare the centering ability and canal transportation of TruNatomy, OneCurve, and Jizai file systems to assess their performance in oval-shaped canals using cone-beam computed tomography imaging.
Materials and Methods: Forty-two fully formed single-rooted mandibular premolars were selected with a buccolingual canal size 2–2.5 times the mesiodistal size at 5 mm from the apex, with 0°–10° canal curvature with a 5–6 mm radius, at 5 mm from the apex. The teeth were divided into three groups (n = 14) and prepared with TruNatomy, OneCurve, and Jizai files based on the manufacturer's instructions. Cone-beam computed tomographic images were taken before and after instrumentation. The canal transportation and centering ability was calculated at 3, 6, and 9 mm from the apex in both mesiodistal and buccolingual directions.
Statistical Analysis: Intergroup comparison was done using Kolmogorov–Smirnov test. Intragroup comparison was done using Freidman test. A comparison of categorical variables was done using the Chi-square test.
Results: The results obtained did not present any statistically significant difference between the three groups, with TruNatomy and OneCurve showing relatively lesser canal transportation and better centering ratio when compared to the Jizai file system.
Conclusions: It can, therefore, be concluded that all three systems used in the study are capable of safely preparing root canals with minimal errors.
