摘要/Abstract

摘要：

畸形根面沟(palatogingival groove,PGG)是一种位于根面的发育性解剖异常,多见于上颌侧切牙。PGG处牙周组织附着薄弱,易滞留菌斑,引起局部牙周炎症,感染可通过根面沟扩散至牙髓组织,最终导致牙周牙髓联合病变。本文报道了1例因畸形根面沟引起的左上颌侧切牙牙周牙髓联合病变,经显微根管治疗联合意向性牙再植术成功保留患牙,并进行文献回顾,探讨了PGG的诊断要点及治疗方案。

Abstract:

Palatogingival groove (PGG) is a developmental anatomical defect located on the lingual root surface, frequently observed in maxillary lateral incisors. The periodontal attachment in this region is delicate, which makes it vulnerable to plaque accumulation and increases the risk of periodontal inflammation, leading to combined periodontal-endodontic lesions. This article reports a case of a combined periodontal-endodontic lesion in a left maxillary lateral incisor caused by PGG. The tooth was successfully preserved through microscopic root canal therapy combined with intentional replantation. Additionally, a literature review was performed to highlight the key diagnostic features and treatment strategies for PGG.

Key words: intentional replantation, palatogingival groove, double root canals, maxillary lateral incisor
