Background: Several rotary Ni-Ti and reciprocating have been evolved with variable tapers, variable pitch diameters, M-wire technology and non cutting tip that are claiming to maintain original canal shape with emphasis on centering ability. Aim: To compare the centring ability, apical third canal transportation and change in canal curvature of different rotary and reciprocating systems, in vitro. Materials & Method: Fifty mesial canals of freshly extracted molars with completely formed apices, angles of curvature 15° - 25° and radii of curvature <10 mm were selected. Teeth were decoronated with a standard length of 15mm and randomly assigned into five groups, which include K3, ProTaper Next, WaveOne, Reciproc and stainless steel hand K-files. Pre–instrumentation and post–instrumentation CBCT were taken. Centring ability, apical third canal transportation and change in angle of curvature were calculated for each group and compared. Statistical Analysis: One way ANOVA and Post Hoc Tukey-B tests were used to analyze the data. Results: With regards to centring ability ProTaper Next showed the maximum centring ability and the least was for Hand K-files. Apical third canal transportation was found to be maximum in Hand K-files and minimal in ProTaper Next. Reciproc produced the least change in canal curvature followed by ProTaper Next, K3 and Hand K-files respectively. Conclusion: Within the limitation of this study, it may be concluded that ProTaper Next has the best centring with least canal transportation. Reciproc proved to be as good as ProTaper Next.
