Abstract
Introduction: In this study OneShape file (OS) was compared to R-endo file (RE) in retreatment of endodontically treated teeth in terms of time required for completion of retreatment procedure and amount of remaining gutta percha on root canal dentin. Methods: Sixty mandibular mesio-buccal canals with angles of curvature between 15 and 45 were prepared using protaper universal rotary files then obturated using guuta-percha and AH-plus sealer. Canals were then divided equally into 2 groups according to the retreatment system. Time required to reach the full working length and for complete removal of gutta-perha were meaured during retreatment procedure using a digital stopwatch. Also the amount of remaining guuta-percha on the root canal dentin was measured using Stereomicroscopic images analyzed by Image J software
