The potential for endodontically treated teeth to fracture increases proportionally to the amount of dentin removed. This risk is even higher in oval roots in which their M-D diameter is much narrower than the B-L, such as the maxillary and mandibular premolars and mesial roots of mandibular molars. The purpose of this paper is to evaluate importance of the centric ability in endodontics. Methods: 90 Mandibular teeth were taken and three groups of 30 each were made. Teeth with previous endodontic treatments, metal restorations, resorptions, incomplete apex formations and multiple visible foramina were excluded. Biomechanical Preparation was with Protaper Next and Protaper Rotary File system and Centric ability was compared. Results: There was a significant statistically difference between Protaper Next Group & Protaper Group and Wave One and Protaper Group. Conclusion: Under experimental conditions, Protaper Next has better centric ability than Wave One and Protaper.
