Introduction: An experimental study was carried out to compare the effect of the manual system and the rotary system on the conformation of curved conduits.
Methodology: A sample of 40 mesial roots of lower first molars was randomized into two equal groups: group manual system of K-files and group rotary system FGK Race®. The radius of the final curvature vs. the initial curvature was compared using the Autocat 2015 program. The t-test with a significance of 0.05 was used.
Results: The curvature radius varied significantly for both the manual system and the rotary FGK Race® (p = 0.0001 and p = 0.0013, respectively). In addition, the manual system produced greater variation in the radius of the curvature when compared to the rotary system 2.23mm vs. 1.27mm respectively; p = 0.13.
Conclusion: Both systems produced modification on the conformation of the conduits of the mesial roots; however, in the comparison between both systems said differences were not significant.
