Abstract
Abstract Introduction: Removal of root canal filling from the root canals is important to allow effective irrigation flow inside the root canals, and adaptation of new root canal filling. Aim To evaluate and compare the efficacy of two rotary retreatment systems (D-Race retreatment kit, Neolix kit) on removal of gutta-percha and bond strength of obturation using Totallfill BC sealer. Materials and methods :Sixty single rooted teeth were decoronated and shaped using Protaper universal system to size F3, then obturated using cold lateral condensation. Roots were divided into two groups according to the type of retreatment kit used. After retreatment, half of the samples were examined under Scanning Electron Microscope (SEM) and the remaining half were reobturated using Totallfill Bioceramic sealer and tested by pushout bond strength test. Data was statistically analyzed by one- and two-way of variance (ANOVA) followed by Tukey’s HSD multiple comparison tests to compare between sub-groups. Results: Results showed that D-race system is more effective in removing root canal filling material compared to Neolix system. The results also showed that the adaptation of bioceramic sealer is affected by the amount of remaining root canal filling material after retreatment. Conclusions: This study suggested that D-race system is more effective in removing root canal filling material compared to Neolix system. The adaptation of bioceramic sealer is affected by the amount of remaining root canal filling after retreatment.
