Description

Extrusion of endodontic sealer into the mandibular canal caused by overfilling root canals during endodontic treatment has a negative effect on the prognosis of endodontically treated teeth. Chemical neurotoxicity and mechanical compression may injure the inferior alveolar nerve (IAN), resulting in sensory disturbances such as pain or paresthesia. This paper briefly reports our experience and reviews the literature pertaining to the treatment of overfilled root canals with extrusion of material into the mandibular canal. In our patient, endodontic filling material extruded from the root apex of the left mandibular first molar and invaded the mandibular canal on that side, causing spontaneous pain in the affected region. A surgical procedure for removal of the material and decompression of the IAN is most effective. A piezoelectric device was used for effective and safe clinical management, providing relief from pain and resolving IAN injury.
