This case report introduces the rare anatomical variation in a maxillary lateral incisor, known as the buccomesial groove (BMG). The BMG is rare and leads to endodontic-periodontal lesions. Due to its subtle presence, funnel-shaped form, and varying depth in the root, it facilitates microbial film adhesion, leading to pathology. A 25-year-old Asian male patient presented with pain in his maxillary left lateral incisor. After comprehensive clinical and radiographic assessments, the diagnosis of pulpal necrosis with symptomatic apical periodontitis associated with BMG in the maxillary left lateral incisor was confirmed. A cone-beam computed tomography preoperatively showed the groove extending from two-thirds of the buccal to the mesial side of the left lateral incisor. This case presents a new anatomical anomaly, highlighting the necessity for precise diagnosis and treatment.
本病例报告介绍了上颌侧切牙一种罕见的解剖变异，即颊近中沟（BMG）。BMG较为罕见，会导致牙髓-牙周病变。由于其存在细微、呈漏斗状且牙根深度各异，它便于微生物膜附着，进而引发病变。一名25岁的亚洲男性患者因上颌左侧侧切牙疼痛前来就诊。经过全面的临床和影像学评估，确诊为上颌左侧侧切牙牙髓坏死伴症状性根尖周炎，与BMG相关。术前的锥形束计算机断层扫描显示该沟从左侧侧切牙颊侧的三分之二处延伸至近中侧。本病例呈现了一种新的解剖异常，凸显了精确诊断和治疗的必要性。
