| Popis: | Today it is more and more preferred to preserve teeth with promising prognosis rather than to extract them. The efficiency and the precision of retreatment files to remove filling material are important factors of successful treatment. The aim of this study was to evaluate the efficiency of MaxWire® alloy file in removing root canal filling material after retreatment with endodontic retreatment instruments. Distal roots of twenty human mandibular molars with single and straight canals were selected for this study. All canals were instrumented up to #40/.04 with Bio-race system and apical preparation was finished with Kfile #50/.02. Obturation was performed using lateral condensation technique with ADSEAL sealer. Radiographs were performed in buccolingual and mesiodistal directions with periapical X-ray after obuturation. Teeth were randomly divided into two groups with ten teeth in each. Group 1: removal of root canal filling material was performed using D-race system. Group 2: removal of root canal filling material was performed using D-race system following XP endo Finisher R instrument. Radiographs were performed after retreatment. Residual material was calculated in percentage left in canals. Statistical significance between the two groups were analyzed with t-test. Remnants of root canal filling material was observed in both groups: 38.90% in Group 1 and 13.71% in Group 2, respectively. There was a significant difference between the groups in term of the total root canal filling material (p |
