Non-surgical management of paraesthesia and pain associated with endodontic sealer extrusion into the mandibular canal.

The aim of this report was to present a case of endodontic sealer extrusion into the mandibular canal in a 42-year-old woman. The patient was referred to the Endodontology and Stomatology Clinics, School of Dentistry, Estácio de Sá University, complaining of 5-day duration intense spontaneous pain and paraesthesia, both arising after an endodontic intervention. Conventional radiographs and computed tomography of the mandible showed the presence of radiopacities inside the right mandibular canal. History and these radiographs confirmed extrusion of endodontic sealer. Treatment included an anti-inflammatory drug, completion of endodontic treatment and follow up. The patient reported gradual improvement, becoming asymptomatic after 2 months. Radiographs 30 months after initial examination revealed partial resorption of the foreign material. In conclusion, iatrogenic extrusion of endodontic materials should be included in differential diagnosis of endodontic pain and can sometimes be managed through non-surgical interventions in some cases.
