Abstract
The most frequent cystic lesions affecting the jaws are radicular cysts, which present radiographically as an oval or pear-shaped unilocular radiolucency in the periapical region. Radicular cysts are usually asymptomatic. This case study describes the surgical treatment of a radicular cyst involving two maxillary anterior teeth. The diagnosis of radicular cyst was confirmed through a clinical and radiographic evaluation. An apicoectomy was performed, and Mineral Trioxide Aggregate (MTA) was placed as the apical barrier. This case report illustrates the effective surgical management of an extensive infected radicular cyst.
