Abstract
:
Aim of the study To compare incidence of dentinal cracks after using of XP-Endo Shaper (FKG Dentaire SA, Switzerland), TRUShape (Dentsply Sirona, OK), ProTaper Next (PTN) and ProTaper Universal (PTU) (Dentsply Maillefer, Switzerland) instruments in preparation of mandibular premolars teeth with oval canals using the micro CT evaluation method. Materials and Methods Thirty-six extracted human mandibular premolars with single oval root canals were distributed randomly to 4 experimental groups (n=9) for root canal preparation: group I, XP-Endo Shaper; group II, TRUShape; group III, ProTaper Next; and group IV, ProTaper Universal. The teeth were scanned using micro-CT with high resolution before and after mechanical root preparation. Then, cross-sectional images of pre-and post-scanning were visualized simultaneously to detect new dentinal cracks. The numbers of dentinal cracks were determined as percentage for each group and the result was statistically analyzed using Wilcoxon Signed Ranks Test and Kruskel Wallis Test. Result Total of 49,628 cross-sectional images were obtained from pre-and post-scanning with micro-CT. Dentinal cracks were viewed in 11,223 of the images (22.6%). No new dentinal cracks were formed after using of XP Shaper, TRUShape or PTN groups. New dentinal cracks were found in PTU group and significant difference was found between pre-and post-preparation dentinal cracks (20.9% vs 34%). Conclusion Under limitation of this study, mechanical preparation with XP Shaper, TRUShape or PTN groups did not induce cracks. Formation of cracks was found after preparation with PTU system. Heat treated files in this study was less likely to induce dentinal cracks than traditional NiTi (PTU).
