Differential diagnosis of endodontic‐related inferior alveolar nerve paraesthesia with cone beam computed tomography: a case report. International Endodontic Journal , 44 , 176–181, 2011. Abstract Aim To discuss the use of cone‐beam computed tomography (CBCT) in the differential diagnosis of a case of labiomandibular paraesthesia caused by extrusion of endodontic sealer into the mandibular canal. Summary A 59‐year‐old woman suffering from a paraesthesia on the left posterior mandible and numbness on the left side of the lower lip was referred to an endodontic specialist 1 month after multiple root canal treatments. A panoramic radiograph revealed the presence of extruded root filling material beyond the apex of the mesial root of the mandibular left second molar and also beyond the apex of the first premolar. A cone beam computed tomography examination was undertaken, which confirmed the presence of radiopaque root canal filling material in the periapical area of the second molar, and revealed that the material was inside the mandibular canal. No extruded filling material was found inside the mental foramen beyond the apex of the first premolar tooth. Key learning points • Small field of view CBCT (where possible) can be considered an effective radiographic diagnostic device when endodontic‐related inferior alveolar nerve or mental foramen paraesthesia are suspected. • CBCT is able to provide detailed three‐dimensional images of the tooth, the root canal system and the surrounding tissue.
