Palatogingival Groove: A Plaque Trap Leading to Bone Loss in a Maxillary Lateral Incisor – A Rare Case Report

Palatogingival grooves are one of the most important anatomical anomalies, typically appearing as indentations on the palatal aspects of maxillary incisors. These grooves are excellent harbor for dental plaque accumulation as they act as a plaque-retentive factor, leading to the development of periodontal diseases. Treatment options for palatogingival grooves include curettage, saucerization, sealing the groove using GIC cement, and endodontic and periodontal therapy. In this case report, we describe a groove located in the palatogingival area of the left maxillary lateral incisors in a male patient and discuss its regenerative management using both nonsurgical and surgical approaches.
