Abstract

Abstract

Objective: The aim of this study was to compare canal aberrations promoted by three nickel-titanium (NiTi) rotary systems in simulated S-shaped canal.
Methods: Glide paths were prepared in thirty simulated S-shaped canal blocks. The blockswere then randomly assigned into three groups (n=10): ProTaper Universal (PTU), ProTaper NEXT(PTN) and iRace (IRA) and prepared per its manufacturer’s recommendation up to apical size #25. Pre-operative images were taken as baseline. Post-operative images were magnified to identify canal aberrations. Intra-operative images were investigated for aberrations occurred between each file used.
Results: PTN produced the least number of canal aberrations, followed by IRA and PTU respectively. The incidences of aberration between PTN and PTU were significantly different (p<0.05).
Conclusion: The ProTaper NEXT system should be the choice for S-shaped canal preparationbecause of the least canal aberrations.
