Evaluation of the Canal Transportation and Centering Ability of Different Rotary NiTi Systems in Simulated Curved Canals (A Comparative Study)

Abstract

Background: Creating a continuous tapered shape while preserving the original root canal geometry particularly in the narrow and curved root canals represents a significant challenge for clinicians.New Niti instruments have been established with new metallurgical and heat treatment, these may play an important role in retaining the original shape of the canal with less mishaps.The study wasaimed to assess and compare the transportation of thecanal and centering ability of three Niti rotary instruments:, EdgeOne Fire,ProTaper Next and TruNatomy filesat different points of simulated curved canals.
