Root canal morphology can be changed after root canal preparation depending on the technique used. Therefore, the object of this study was to use micro-CT to investigate the shaping ability of the ProTaper rotary system and stainless steel manual files in permanent premolars. Material and methods Sixty extracted upper premolars were used for this study. They were divided into 2 groups of 30 teeth each. Before preparation, all samples were scanned by micro-computed tomography. Thirty teeth were prepared with the ProTaper system and the other 30 with stainless steel files. The root canal models before and after preparation were reconstructed and superimposed, and the volume, surface area and diameter changes were quantitatively measured in 3D analysis with SkyScan according to preparation techniques. F test and t test showed a statistically significant difference in the root canal diameter increase between the ProTaper group and the manual instrumentation group (P < 0.000001). The ProTaper system produced a greater volume change than the manual instrumentation technique (P < 0.001). The ProTaper system produced a greater change in surface area than the manual instrumentation technique (P < 0.00001). ProTaper system produced significantly increased root canal diameter, volume and surface area when compared with the manual instrumentation technique. [ABSTRACT FROM AUTHOR] |
