Palatogingival groove (PGG) is an anomaly in the maxillary anterior teeth, often accompanied by the area of bony destruction adjacent to the teeth with no carious or traumatic history. The hidden trap in the tooth can harbor plaque and bacteria, resulting in periodontal destruction with or without pulpal pathologic change. Related diseases can involve periodontal destruction, combined endodontic-periodontal lesions, or separate endodontic and periodontal lesions. Disease severity and prognosis related to PGG depend on several factors, including location, range, depth, and type of the groove. Several materials have been used and recommended for cases of extensive periodontal destruction from PGG to remove and block the inflammatory source and recover the health of surrounding periodontal tissues. Even in cases of severe periodontal destruction, several studies have reported favorable treatment outcomes with proper management. With new options in diagnosis and treatment, clinicians need a detailed understanding of the characteristics, treatment, and prognosis of PGG to successfully manage the condition.
腭龈沟（PGG）是上颌前牙区的一种异常情况，常伴有牙齿相邻区域的骨质破坏，且无龋齿或外伤史。牙齿中的隐蔽陷阱可藏纳菌斑和细菌，导致牙周破坏，伴或不伴有牙髓病理改变。相关疾病可包括牙周破坏、牙髓-牙周联合病变或单独的牙髓和牙周病变。与PGG相关的疾病严重程度和预后取决于多个因素，包括沟的位置、范围、深度和类型。对于因PGG导致广泛牙周破坏的病例，已使用并推荐了多种材料来清除和阻断炎症源，恢复周围牙周组织的健康。即使在严重牙周破坏的病例中，多项研究也报道了通过适当管理可取得良好的治疗效果。随着诊断和治疗的新选择出现，临床医生需要详细了解PGG的特征、治疗和预后，以便成功处理该病症。
