The aim of this study was to assess the efficacy of lasers in removing filling remnants from oval-shaped canals after retreatment procedures with rotary instruments using micro–computed tomographic imaging.The root canals of 42 mandibular canines were prepared and obturated using the warm vertical compaction technique. Retreatment was performed with rotary instruments, and the specimens were distributed...
AimTo evaluate the bond strength of a resin‐based sealer (AH Plus) to root canal dentine after the removal of a zinc oxide‐eugenol–based sealer (Endofill), using different retreatment techniques.
MethodologyThe root canals of sixty‐four maxillary incisors were prepared with ProTaper and filled with Endofill/gutta‐percha. After thermocycling, the roots were randomly assigned according to the retreatment...
