A palatogingival groove of the maxillary lateral incisor is an anatomic malformation, which always predisposes the tooth to pulpal and periodontal disease. The diagnosis and treatment planning become complicated, with uncertain prognosis. Herein, we present an effective interdisciplinary management of a case of combined periodontal-endodontic lesions caused by palatogingival grooves. A series of treatment modalities were undertaken to preserve the two teeth, including root canal treatment, periodontal initial therapy, splinting the mobile teeth, occlusal adjustment, apical microsurgery, grinding and sealing grooves, and guided tissue regeneration. An apparent healing of the lesions was visible after 12 months. Therefore, interdisciplinary management of combined periodontal-endodontic lesions with palatogingival grooves of the maxillary lateral incisors is necessary for a favourable long-term outcome.
