[Overfilling into the mandibular canal as an endodontic complication. A review].

As a consequence of traumatic and toxic injury of the inferior alveolar and the mental nerves, disturbances of sensibility may develop during and after root canal treatment. Several reasons are possible. In most cases, however, such disturbances are the result of root canal filling materials that have been pressed into the mandibular canal. Based on all cases reported in the literature, this review summarizes and discusses symptoms, therapy, prognosis and prophylaxis of such sensibility changes following endodontic overfilling into the mandibular canal.
