Abstract:

Invasive oral cavity treatment is associated with the risk of inferior alveolar nerve injury. Root canal therapy as the root cause of this injury is rare but may lead to severe neurologic complications. This report presents two patients who complained of neurologic complication after overextension of canal filling material during endodontic treatment. Clinical manifestations, X-ray imaging, and prevention and treatment measures were discussed with the aid of available literature to provide references for avoiding such risks in clinic.

Key words: root canal therapy, complication, mandibular canal, never injury, cone beam computed tomography
