Radicular cysts or periapical cysts are the most common cystic lesions in the jaws. They arise from the epithelial remnants in the periodontal ligament as a result of the stimulus from periapical infection following pulpal necrosis. They are found mostly near apex of the teeth. Most radicular cysts are of smaller size of around 1.5 cm, but they can even extend up to 5-6 cm. In the maxilla, sometimes, a cyst may involve the entire maxillary sinus. Radiographically most radicular cyst appears as a pear shaped unilocular radiolucent lesion in the periapical region attaching the affected tooth root. This case report presents the successful surgical and endodontic management of large infected radicular cyst involving over half of the palate in anterior maxilla region. Pathogenesis, clinical features, and treatment options are discussed.
