Damage to the inferior alveolar nerve(IAN) is a relatively infrequent complication in endodontic treatment. However, endodontic overfilling involving the mandibular canal may cause an injury of the inferior alveolar nerve resulting in sensory disturbances such as pain, dysesthesia, paresthesia or anesthesia. Two mechanism(chemical neurotoxicity and mechanical compression) are responsible for the IAN injury. When absorbent materials overfilled, it can be treated as a non-surgical procedure. But early surgical intervention required when mechanical, chemical nerve damage expected. We report surgical removal of overfilled gutta-percha and IAN decompression through sagittal split osteotomy in case of dysesthesia after overfilling of endodontic material into the mandibular canal. Dysesthesia recovered 3 months after surgical treatment.
