Treatment of intrusive-luxated tooth, Report of a case

Abstract

A case of replantation of an intrusive-luxated tooth is reported. The patient was a 14-year-old boy, and he had knocked his maxillary anterior region against a desk at school. About 20 minutes after the injury he visited the dental clinic. Clinical and radiographic examinations revealed that his left maxillary incisor had completely intruded into the alveolar socket, but perforation of the nasal cavity, fructure of the alveolar bone or tooth-root was not noted. Under local anesthesia, the intrusive-luxated incisor was replanted and fixed by direct bonding method. Four days after the replantation, pulp extirpation and root canal filling were performed, since a clinical examination showed the replanted incisor was non-vital. Extirpated pulp tissue showed histopathologically necrobiotic or coagulation necrotic change with infection of the Gram-positive cocci. Two months after the replantation, the fixing appliance was removed, since the postoperative course was uneventful, and tooth movility of the incisor was in the normal range. In addition to the present case, treatment, prognosis and histopathology of luxated teeth are discussed.
