Conservative management of a large dentigerous cyst in a 6-year-old girl: a case report.

Dentigerous cysts are benign odontogenic cysts that are associated with the crowns of permanent teeth. They are usually characterized as unilocular radiolucent lesions and are rarely seen during childhood. The purpose of this article was to report the case of a 6-year-old girl with a dentigerous cyst associated with the tooth buds of premolars. The therapeutic approach included extraction of the primary molar involved and marsupialization of the lesion. After 21 months of follow-up, spontaneous eruptions of the impacted premolars were noticed. In conclusion, marsupialization might be the first treatment option for conservative management of dentigerous cysts in children.
