Dentigerous cyst enucleation

Abstract

Dentigerous cyst is a type of odontogenic cysts and generally occurs in the ages of twenties or thirties. Dentigerous cyst always includes a tooth which cannot complete the eruption process and occurs around the crown by the fluid accumulation between the layers of enamel organ. In rare cases, dentigerous cyst occurs in the first decade of life and develops in an immature permanent tooth as a result of a chronic inflammation of overlying nonvital primary tooth. In this report, a case of dentigerous cyst in primary dentition in a 9-year-old child patient and its treatment were presented. The standardized treatment for a dentigerous cyst is enucleation and extraction of the involved tooth. In cases of larger cysts, an initial marsupialization to diminish the size of the osseous defect, followed by enucleation and tooth extraction, has been advocated. However, if the patient is a child and the cyst is small, removal of cystic lining followed by extraction of deciduous tooth usually results in disappearance of the cyst and preservation of the permanent tooth. When dealing with larger lesions, enucleation and tooth extraction have been favored. This can lead to functional, cosmetic, and psychologic consequences for the child.
