Abstract

Purpose
A successful root canal preparation is to remove infected dentin and pulp tissue and to obturate the canal three-dimensionally. This study aimed to compare the centering ability of Protaper Ultimate and RevoS+ rotary file systems in curved canals of printed mandibular first molars by using micro-computed tomography (micro-CT).
Materials and Methods
In this in-vitro study, 16 mandibular molar teeth were printed from resin with 45° mesial root curvature. Root canal preparation was performed according to the specified groups, either Protaper Ultimate or RevoS+. The pre-and post-preparation images were repositioned in all three spatial planes by DataViewer. All images were imported into the CTAn software for the calculation of the centering ability and transportation values.
Results
The results showed no significant differences between the Protaper Ultimate and RevoS+ groups in terms of the centering ratio in the most inclined part of the canal. There were also no significant differences between the groups in canal transportation. (p>0.05)
Conclusions
Protaper Ultimate and RevoS+ rotary file systems showed similar ability in centering ratio and canal transportation in curved canals from printed mandibular molars.
