Endodontic–periodontal management of a maxillary lateral incisor with a deep palatogingival groove
A case report
The existence of pulpal and periodontal disease can complicate the diagnosis and treatment planning and affect the sequence of care to be performed. A palatogingival groove is a developmental anomaly that often leads to the establishment of combined periodontal–endodontic lesions and can be an unidentified cause of endodontic failure. This case report describes a case of palatogingival groove in an upper right lateral incisor with endodontic failure. The diagnosis was confirmed with the help of spiral computed tomography and management included a combination of re-endodontic therapy and periodontal therapy.
