ABSTRACT
Introduction:
Nickel-titanium rotatory systems should remove dentin during the root canal preparation to promote the enlargement and tapered shape with continuously narrowing towards the apex.Objective:
The aim of this study was to analyze the cutting ability of three NiTi rotatory systems (n = 12) ProTaper (group 1), Mtwo (group 2), and K3 (group 3). Material andmethods:
Thirty six maxillary molar teeth were weighted on an analytical balance before and after the rotatory preparation of the mesio-buccal root canal. Data was statistically analyzed by ANOVA and Tukeys test with a significance level of 5%.Results:
The results revealed the following mass differences (g) before and after the root canal preparation ProTaper (group 1 - 0.0159 ± 0.004), Mtwo (group 2 - 0.0125 ± 0.002), and K3 (group 3 - 0.007 ± 0.003).Conclusion:
ProTaper showed the highest cutting ability among the three tested nickel-titanium rotatory systems followed by Mtwo and K3.
