Abstract

Nonsurgical treatment of root canal failure entails thorough removal of root canal filling material. The objective of this study was to analyze the difference in cleaning of root canal filling material with use of continuous rotary motion (ProTaper Universal Retreatment System) and reciprocating motion (Reciproc® Blue). Forty-two mandibular premolars extracted post-endodontic treatment were divided into two equal groups. Group 1, R25 (reciprocating system, n = 21) and group 2, ProTaper Universal Retreatment System (rotary system, n = 21). Samples were scanned using micro-computed tomography; data were reconstructed and analyzed by CTAnalyser (Bruker). Volume of residual filling material was calculated. Differences between the groups were assessed using Mann-Whitney test (p < 0.05). All examined teeth had remnant filling material within the canal. There were no significant differences between the groups with respect to residual volume of filling material. The reciprocal motion instrument removes more filling material from the root canal than the rotary motion instrument, especially from the 1/3 apical area.
