title: Cavitational bone defect: a diagnostic challenge.
abstract: A patient with a history of trauma to the maxillary left anterior region presented with chronic pain of unknown etiology. Root canal therapy and periradicular surgery failed to resolve the persistent pain. A second surgical procedure revealed a bone cavity superior and distopalatally to the apex of the maxillary left lateral incisor. The suspected etiology was necrotic bone removed from the bone cavity.
