Management of a root fracture in an immature permanent tooth.

A 9-year-old girl with trauma to the maxillary right permanent central incisor is reported. Clinically the tooth appeared extruded with one third of the root visible. The radiographic examination revealed a root fracture. The extruded tooth was repositioned and splinted with a heavy wire and adhesive resin, after which a resorbable collagen tissue was placed to cover the buccal region. Subsequent to the injury, swelling was observed and the patient complained of pressure pain in the periapical region of the tooth with no response to electric pulp testing. It was treated successfully with periodontal therapy and endodontic therapy with Vitapex.
