Management of large radicular cyst by conservative surgical approach: a case report.

Radicular cysts are the most common cystic lesions which affect the jaw. They are most common among all the jaw cysts and comprise about 52% to 68% of the entire cysts which affect the human jaw. They are generally symptomless and are diagnosed during routine radiologic investigations. The treatment of radicular cysts includes conventional nonsurgical root canal therapy when lesion is localized or surgical treatment like enucleation, marsupialization or decompression when lesion is large. This case report presents the successful surgical management of a large infected radicular cyst which was associated with maxillary central incisor with open apex.
