Background: To measure and compare canal transportation and centering ratio of WaveOne GOLD, Reciproc Blue and TwoShape file systems using Cone Beam Computed Tomography and exporting images into Adobe photoshop software. Materials & Methods: Sixty tooth samples were randomly divided into three groups. Wave One Gold Group, Reciproc blue Group and Two-Shape Group containing twenty tooth samples in each group. Wave One Gold and Reciproc blue group operated in reciprocating motion. Two-Shape group operated in continuous motion. All the observed values were noted and statistical analysis was done using IBM SPSS Version 20 software (IBM Corp., Armonk, NY, USA). Results: The comparison of canal transportation between the study groups at various levels and the results are statistically insignificant. There were no significant differences in canal transportation between groups at any of the levels studied. At level 7, less canal transportation was observed in the 2 Shape group (0.091) compared to Wave One Gold (0.093) and Reciproc Blue (0.1). Conclusion: WaveOne Gold showed better centering and less canal transportation than Reciproc blue and 2 Shape. Least centering and more transportation was observed with 2 Shape file system.
Keywords: Waveone gold, Twoshape, Reciproc blue.
