Abstract
1.1 Aim: The aim of the present study was to compare the canal transportation and centering ability of Rotary Wave One gold, True Shape using cone beam computed tomography (CBCT) in root canals to find better instrumentation technique for maintaining root canal geometry.
1.2 Materials and Methods: Total 10 freshly extracted premolars having Straight root canals were divided into two groups of 5 teeth each. All teeth were scanned by CBCT to determine the root canal shape before instrumentation. In Group 1, the canals were prepared with the True Shape file system,in Group 2 the canals were prepared with Rotary Wave One Gold files . After preparation and post-instrumentation scan was performed. Pre-instrumentation and post-instrumentation images were obtained at three levels, 3 mm apical, 3 mm coronal and 8 mm apical above the apical foramen were compared using CBCT software. Amount of transportation and centering ability were assessed. The two groups were statistically compared with analysis of variance and Tukey honestly significant.
1.3 Results: All instruments maintained the original canal curvature with significant differences between the different files. Data suggested that True Shape files presented the best outcomes for the variables evaluated. True Shape files caused lesser transportation and remained better centered in the canal than Rotary Wave One Gold files.
1.4 Results:
1.5 Conclusion: The canal preparation with True Shape files showed lesser transportation and better centering ability than Wave One Gold filing system
