Introduction: Endodontic retreatment consists in removing the filling material to disinfect the root canal system. Conventionally, files have been used, however, the material cannot be completely removed. Objective: To evaluate the efficacy of remove filling using the operating microscope, Clearsonic® ultrasonic tip and an experimental remove filling system (ERFS) composed of Infiniteeth® microexplorers and Dentsply® spreaders as an adjuvant to Reciproc Blue® files. Materials and methods: 32 distal roots of mandibular molars were used. The samples were filled and evaluated by radiography and cone beam computed tomography to measure the initial filling volume, then deobturated with Reciproc Blue® R40 files, the residual filling material was evaluated by radiography and measured with cone beam tomography. The samples were divided into 2 groups: remove fillings with an operating microscope (n=16) and deobturation without an operating microscope (n=16). Both groups were treated on a phantom head to achieve indirect vision. Both groups had 2 subgroups that evaluated the remove fillings using Clearsonic® and the ERFS with a total of 4 subgroups (n=8), the time was counted in minutes and the volume of residual material was measured with cone beam tomography. Results: The subgroups of remove fillings with an operating microscope with Clearsonic® and the ERFSwere those that left the least amount of residual material with 18.85% and 13.9% respectively without significant difference (Anova p=0.174) but they were the ones that took the longest to perform it with 7.10 and 8.63 minutes respectively (Tukey p<0.05). Conclusion: The operating microscope reduces the amount of residual filling material significantly compared to not using it, but makes the proceduretly slower. SDE and clearsonic® reduce residual material without significant difference.
