Abstract

Aim: The purpose of this study was to compare the canal transportation, centering ability, canal curvature, dentin removal, the volume of the curved root canals, and time taken during and after instrumentation with Wave One, Reciproc, F360, and One shape (OS) by using cone-beam computed tomography (CBCT). Materials and Methods: According to the file systems used for canal preparation, eighty mesiobuccal canals of mandibular molars were distributed into four groups (20 samples each): OS (Group 1), F360 (Group 2), Wave One (Group 3), and reciproc (Group 4). According to the manufacturer's instructions, all groups were prepared until size 25 taper. Canals were scanned using CS three-dimensional CBCT scanner (Carestream) before and after preparation at 2 mm, 5 mm, and 8 mm from the apex. The data collected were evaluated using SPSS software with ANOVA and post hoc for a significant difference. Results: Significant difference was found between the entire group at 2 mm and 5 mm (P = 0.021) and at 8 mm (P = 0.037), where F360 showed the least canal transportation. The mean values for centering ability were not found significant at 2 mm and 5 mm. OS proved to remain more centered than the other groups. Curved canals were instrumented better with minor canal straightening by using Reciproc. The dentin was removed more by using Wave One, whereas least dentin was removed by F360. During pre- and post-instrumentation scans the change in volume of the root canal were not found statistically significant. Wave One showed the maximum increase in the volume of the canal after instrumentation. For the preparation of the canal, the time taken was less with reciproc as compared to other groups. Conclusion: Therefore, according to the study single-file rotary instrument like F360 used in the continuous rotation is suitable instrument for the root canal preparation followed by Reciproc, OS, and Wave One.
