Conservative Treatment by Marsupialization of Dentigerous Cysts in Children: Report of three Cases

Abstract

Dentigerous cyst is the most common developmental odontogenic cyst. The standard treatment is enucleation of the cyst and extraction of the involved tooth. However, if the patient is a child, marsupialization may be advisable to allow eruption of a cyst-associated unerupted tooth, as a conservative and definitive treatment. This case report presents three cases of dentigerous cysts in children.Two of the cases, lesions were detected at the right side of the mandible and associated with second primary molar and unerupted second premolar. One of the cases the lesion was detected at the right side of the maxilla and associated with first primary molar and unerupted first premolar. Patients were treated by extraction of the primary molars and marsupializing the cyst cavities. At 9 months follow up visits showed that the cystic lesions had resolved and the premolars were ready to erupt.Because of the children have a great regenerative potential in bony structure and the teeth with incomplete root development maintain the eruptive strength, marsupialization is a conservative approach for treating dentigerous cysts in children.
