Aim: The aim is to determine the effectiveness of rotary instrumentation (ProFile 0.06 tapered rotary NiTi instruments) in conjugation with solvent (chloroform) in the removal of resilon compared to gutta-percha during root canal retreatment. Materials and Methods: Sixty recently extracted human mandibular permanent premolars with straight roots with single canals were used. Decoronation of samples done at cementoenamel junction using the diamond disk. The length of each canal was determined with a size 15 K file and canals were instrumented using a crown down technique with ProFile 0.06 tapered NiTi rotary instruments. Irrigation done followed by obturation. Result and Conclusion: Statistical evaluation was done using paired t-test (P < 0.05) which showed that the samples obturated with resilon showed significantly better results at the apical third when compared to samples obturated with gutta-percha and the time required for Group 2 is significantly less than Group 1.
