This case report describes the occurrence and treatment of an adenomatoid odontogenic tumor (AOT) presenting as a periodontal intrabony defect on a upper lateral incisor. Following incision and flap reflection, a solid, rubbery specimen was enucleated in one piece leaving a wide moat-like intrabony defect. A bioabsorbable membrane of glycolide and lactide copolymer was sutured over the defect to maximize regeneration and the flaps then sutured over the membrane. Microscopic analysis of the biopsied specimen revealed dental hard tissue interspersed in a field of odontogenic epithelium in a glandular configuration, consistent with a diagnosis of AOT. AOT is a rare odontogenic tumor usually associated with unerupted teeth or dentigerous cysts, not periodontal defects. Clinical evaluation 6 months postoperatively revealed restoration of clinical attachment and periodontal health.
本病例报告描述了一例发生在上颌侧切牙处表现为牙周骨内缺损的腺样牙源性肿瘤（AOT）的情况及治疗过程。切开并翻开黏膜瓣后，完整摘除了一个质地坚实、似橡胶的标本，留下一个宽的护城河样骨内缺损。将乙交酯和丙交酯共聚物的生物可吸收膜缝合覆盖在缺损处，以最大限度促进再生，然后将黏膜瓣缝合在膜上。对活检标本的显微镜分析显示，牙硬组织散在于呈腺管状结构的牙源性上皮区域内，符合AOT的诊断。AOT是一种罕见的牙源性肿瘤，通常与未萌出牙齿或含牙囊肿相关，而非牙周缺损。术后6个月的临床评估显示临床附着和牙周健康得以恢复。
