Apicectomy along with cyst enucleation is typically done as a retreatment strategy in case of failed non-surgical root canal therapy which has associated cyst. Several factors such as a complex root canal system or past procedural mishaps may hinder the accomplishment of non-surgical retreatment. Radicular cysts are generally symptomless unless infected and are diagnosed during routine radiographic examination. The treatment of radicular cyst includes traditional non-surgical root canal therapy when lesion is localized or surgical treatment like enucleation, marsupialization or decompression when the lesion is large.
This case report presents the successful surgical management of a large infected radicular cyst which was associated with maxillary central and lateral incisor.
