| مستخلص: | The aim of this study was to compare the effectiveness of a reciprocating file (Reciproc) and a rotary retreatment file (Mtwo retreatment [Mtwo-R]) for the removal of filling material during root canal retreatment. A total of 30 mandibular molars with a mesial root curvature between 20° and 40° were selected and prepared using a Reciproc R25 file. The canals were filled using the lateral condensation technique and a root canal sealer. The specimens were randomly allocated into 2 groups according to the retreatment technique used (n = 15): a Reciproc R25 file or Mtwo-R 15/.05 and 25/.05 files. After retreatment, the specimens were longitudinally sectioned and photographed with an operating microscope under ×10 magnification. The percentage of total remaining filling material and the percentages in the cervical, middle, and apical thirds of the specimens were calculated. The Student t test was used for statistical comparisons of the 2 groups, and the analysis of variance followed by Tukey test was used to verify differences among the root thirds within each group. No statistically significant difference between the 2 groups was detected in the percentage of total remaining filling material (P = 0.87) or the percentage in any of the thirds of the root canals (P > 0.05) after reinstrumentation. In both groups, there was a significantly greater amount of remaining material in the apical third (P < 0.05). The results suggested that there is no difference between the 2 systems in their effectiveness at removing filling material.
