Abstract
The aim of this study was performance of different rotational speed of XP-endo finisher R for root canal filling removal on mandibular premolar regarding the amount of debris extrusion, completeness of removal and operation time. Thirty-six extracted human mandibular premolars were prepared and filled. Then, the root canal filling was first removed with pilot file system until reached the working length. After that, samples were divided into three groups according to the speed of XP-endo Finisher R, 800, 900, 1,000 rpm, respectively. During root canal filling removal, vial was used to collect apically extruded debris. The radiographs before and after using of XP-endo Finisher R were taken and compared for evaluating the completeness of root canal filling removal while operating time for root canal filling removal was record. Statistical analysis was performed by using Kruskal-Wallis test with statistical significance level at 0.05. Debris extrusion and root canal cleanliness were not different among the 3 groups. However, there was a statistically significant difference regarding the operating time. Rotational speed at 1,000 rpm demonstrated less operation time than 800 rpm. In conclusions, Different rotational speed of XP-endo finisher R did not influence Debris extrusion and root canal cleanliness. During retreatment, at 1,000 rpm rotational speed use less operation time than 800 rpm.
