Aim: To compare the dentinal damage induced by stainless steel hand and rotary nickel-titanium instruments using K files, ProTaper Universal, Neoniti A1 and iRaCe files. Materials and Methods: Sixty single rooted premolars were collected and randomly divided into four groups of 15 teeth each. Group 1- Stainless steel K Files, group 2–ProTaper Universal, group 3- Neoniti A1 file and group 4 - iRaCe rotary instruments. Cleaning and shaping was done with the respective files. The roots were then cut horizontally at 3mm, 6mm and 9 mm from apex and were examined under stereomicroscope. The sections were checked for dentinal defects. Statistical analysis: Groups were analysed with the Fishers exact test. Results: It was found that all instruments examined caused dentinal defects with maximum defects in the apical third. Neoniti A1 file showed least number of dentinal defects compared to other file systems. Conclusion: The present study revealed that all the instruments could result in an increased chance for dentinal defects.
