Introduction: Successful root canal therapy depends on effective debridement of the root canal by eliminating debris and microorganisms and shaping of the root canal system without deviating from the original anatomy. The ability to keep the instruments centered in curved canals and to deliver an accurate enlargement to the root canal without any unnecessary weakening to the root structure is crucial. Aim: This study aimed to compare the canal-centering ability of Protaper gold, WaveOne (WO), Wave one gold file systems using cone-beam computed tomography. Materials and Methods: In this in vitro study, forty extracted human single-rooted mandibular premolars were used. Pre instrumentation CBCT of all teeth were taken, canal curvatures were calculated, and the samples were randomly divided into two groups with ten samples in each group: Group 1–Protaper gold, Group 2–Wave one system, and Group 3- Wave one gold file system. Post instrumentation scans CBCT performed, analysed both the CBCT using DICOM software, to determine the canal-centering ability at 3 mm, 8 mm and 12 mm from the root apex. Statistical analysis: One-way anova and post hoc tests were used for statistical analysis in the present study. The mean and standard deviation values for canal-centering ratio was determined at the levels of 3, 8 and 12 mm between three groups, shaped with protaper gold, wave one and wave one gold file systems. Results: Using one way anova and post hoc, results were as follows: for canal-centering ability, Group 1 (Protaper gold), Group 2 (Wave one), Group 3 (Wave one gold) showed no statistically significant difference at 3 mm, 8 mm, and 12 mm (p>0.05) with slightly higher canal centering ability for the wave one file systems. Conclusion: Within the limitation of this study, Wave one file system has better canal-centering ability, maintains original canal curvature, and preserves more dentine as compared to wave one gold, protaper gold file systems.
