Abstract

It was aimed to investigate the presence and amount of debris in isthmuses of mesial root canals of mandibular molar teeth after use of XP-endo Shaper (XPS), One Curve (OC), and Reciproc Blue (RPC Blue) single-file systems histologically. In total, 36 roots having isthmuses between mesial canals were instrumented using XPS, OC, and RPC Blue files (n=12 isthmus/group). Specimens were examined histologically, and the percentage of debris was measured in all canal thirds. Twoway analysis of variance and post-hoc Tukey test were used to analyze the data at 5% significance level. The percentage of debris was significantly lowest in the RPC Blue group at all root canal levels (P<0.05). There was no significant difference between XPS and OC groups (P>0.05). More debris was found in the apical third than other thirds in all groups (P<0.05). Debris in isthmuses after using RPC Blue files was significantly lower than XPS, and OC groups. Final debris in isthmus can negatively alter the prognosis of endodontic treatment. Hence remaining debris after using different instruments should be known.
