title: Repair of an intrabony defect from an adenomatoid odontogenic tumor.
abstract: 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.
