Clinical study of radicular cysts arising in deciduous teeth

Abstract

A radicular cyst is the most common odontogenic jaw cyst in adults. However, this cyst rarely occurs in children. Radicular cysts originating from deciduous teeth are particularly rare. We clinically analyzed 9 radicular cysts arising in deciduous teeth that were diagnosed by pathological examination at our department between 1971 and 1998. The ratio of boys to girls was 1.25: 1. The average age on presentation of this cyst was 9.9 years, with a range of 7 to 12 years. Extraction of the affected tooth and marsupialization of the cyst was performed to treat most of the deciduous teeth. The prognosis of all patients was favorable, and no recurrence has occurred.
