The purpose of this paper is to present two cases of dentigerous cyst associated to permanent teeth in children treated by conservative techniques.
Dentigerous cyst is the most common developmental cysts of the jaws.
Conservative treatment is very effective to this entity and aims at eliminating the cystic tissue and preserving the permanent tooth involved in the pathology.
Two techniques are described as conservative treatment for these cysts, marsupialization and the decompression. Two children presented with dentigerous cysts.
A female child was affected by a large lesion at the right side of the mandible associated to tooth 45. The other lesion arose at the left maxilla associated to tooth 21 of a male child. Each dentigerous cyst promoted severe tooth displacement.
The first patient was treated with decompression and the second with marsupialization.

Dentigerous cyst is the most common odontogenic development cyst. It can involve any included tooth, although molars and canines are the most affected ones. Cystic formation involving the crown of premolars and incisives is rare.
The classic treatment for dentigerous cysts is enucleation and extraction of the involved tooth. In large cysts, an initial marsupialization can reduce the size of the bone defect before definitive enucleation.
Since this cyst has a large prevalence in children, marsupialization can be advisable as definitive treatment to allow the eruption of the permanent tooth involved.
