Background and Aims: Cleaning and shaping is one of the most important stages in endodontic treatment. Single-file systems save time and reduce the risk of transmission of pathogens. This in vitro study was aimed to compare the rate of canal transportation after the preparation of the stimulated resin root canal with two single-file systems, namely Waveone and Reciproc.
Materials and Methods: Thirty stimulated resin root canal blocks with size 8/0. 02 K file were randomly divided into two study groups. The preparation in Group A and Group B was performed using Reciproc and Waveone files, respectively. Pre and post- preparation photographs were taken and the images were superimposed to evaluate the inner and outer wall’s curvature tendency at three points (apical, middle and coronal) using AutoCad pragram. Data were analyzed using T-test.
Results: Based on the results, the degree of transportation in the inner and outer walls of the canal was less at the level of 3 millimeters (P<0.001) and there was no significant difference between the two groups regarding the deviation at the levels of 1 and 5 millimeters (P>0.05).
Conclusion: Waveone showed better performance in the middle third of canal and this system maybe recommended.
