LARGE ODONTOGENIC INFLAMMATORY CYST ASSOCIATED WITH IMPACTED TEETH: DIAGNOSIS AND TREATMENT

Radicular cysts are defined as a cavity lined by epithelium and with development related to an inflammatory stimulus. We will approach, through a clinical case report, the method of diagnostic evaluation based on histopathologic criteria, as well as the surgical treatment choice of an inflammatory cyst with clinical characteristics of aggressive lesions. A male patient with an intra-osseous lesion associated with impacted teeth was evaluated. Due to the extension of the lesion, 2 surgical stages were chosen. At the first moment, aspiration, marsupialization, and incisional biopsy were performed. The result was compatible with a radicular cyst. In the second surgical stage, the cyst was enucleated and elements 37 and 38 removed, and intermaxillary block was performed with the purpose of preventing jaw fracture. The material was sent to histopathology study, with a final diagnosis of inflammatory cyst. Especially in extensive lesions, the definitive diagnosis must be made before performing more radical surgical procedures.
