A case report is presented of a 14-year-old girl with a buccoapical fistula of tooth 22. The radiograph of the tooth revealed a periapical radiolucency and two roots. Endodontic treatment was conducted, followed by normal healing of the periapical area. Root division and additional roots of maxillary lateral incisors are rare phenomena.
