Shaping Ability of Different Rotary and Reciprocating File Systems in Stimulated S- Shaped Root Canals

Abstract

Objective: In order to recreate S-shaped root canals, this study looked at the shaping capabilities of six rotary and reciprocating file systems as well as hybrid techniques.

Methodology: 20 S-shaped blocks of thermosetting epoxy resin that are radiopaque were grouped based on the biomechanical preparation technique. Using TruNatomy, Procodile, VDW Rotate, Hyflex CM, OneCurve, and WaveOne Gold, six groups of fifteen canals each were created. Following an assessment of the performance of the separate systems, two further hybrid groups (n=15 each) were added: Procodile/Hyflex CM and Procodile/TruNatomy.  All groups were statistically compared with analysis of variance and Tukey honest significant difference test (p<0.05).

Results: The greatest and most cautious diameter increase was produced by Hyflex CM in all three thirds (coronal, middle, and apical; p<0.001). In the coronal and middle thirds, Procodile had the best centering ability (p0.001), whereas TruNatomy produced the least amount of canal transportation and the greatest amount of centering preparation in the apical third (p0.001). In the middle third, hybridization of Procodile and Hyflex CM resulted in a small amount of canal transit and the best centering ability (p0.001). Throughout canal preparation, no ledge, elbow, or apical zip formation was seen, and no tool failure happened.

Conclusion- The middle section of the canal exhibited the least amount of canal transportation and the best centering capability.
