Abstract
Background: This study is aimed to evaluate and compare the occurrence of dentinal cracks after root canal preparation with three different single-shape rotary file-systems using a stereomicroscope. Materials and Methods: Sixty extracted single rooted teeth were selected and divided into three experimental groups and a negative control group of 15 each. The canals were prepared in the experimental groups. Group I - TruNatomy, Group II - HyFlex EDM, Group III - XP-endo Shaper. No preparation was done in the control group (Group IV). The roots were sectioned at 3, 6, and 9 mm from the root apex, and the surfaces were examined under a stereomicroscope. The data were analyzed using the Chi-square, and Fisher's Exact tests. Results: No cracks were seen in the control group. XP endo shaper files showed significantly fewer cracks (P > 0.05) at 3, 6, and 9 mm. No significant difference was observed among TruNatomy and XP endo shaper groups at 6 mm (P > 0.05). The HyFlex EDM files produced higher cracks when compared with the other groups (P > 0.05) at 3, and 9 mm. Statistically, no significant difference was present in dental crack scores among various groups at coronal, middle, and apical portions. Conclusion: All rotary instruments cause dentinal microcracks; with increased frequency in the apical root dentin. XPS caused significantly less dentinal damage than TRN and HEDM systems. TRN caused fewer microcracks than HEDM in the coronal and apical thirds.
