ABSTRACT

Introduction: This Study Compared The Effect Of 2 Rotary Nickel-titanium (NiTi) Systems; WaveOne And ProTaper Universal On Transportation, Centering Ability And Volumetric Changes Of Curved Root Canals. Methods: Thirty-four Mesiobuccal Root Canals Of Mandibular Molars (with Angles Of Curvature Ranging From 25�-35�) Were Randomly Divided Into Two Groups (n=17); WO And PU Groups. Canals Were Scanned Using A Cranex� 3Dx Machine (Soredex, Tuusula, Finland) Before And After Preparation. Root Canal Transportation And Centering Ratio Were Evaluated At 3, 5, 8 Mm From The Apex. Amount Of Removed Dentin Was Evaluated As Well. The Significance Level Was Set At P ? 0.05.

Results: There Was No Significant Difference Between Both Systems In Canal Transportation, Centering Ability And Volumetric Changes.

Conclusions: Both Systems Can Effectively Shape Curved Root Canals, While Preserving Original Canal Curvature, And Without Excessive Removal Of Dentin.
