A Dentigerous Cyst (DC) is the most common developmental odontogenic cyst that mostly happens in patients between 10 to 30 years of age. It is usually completely asymptomatic and is discovered on a routine radiographic examination or to evaluate the reason for an erupted tooth. Radiographically, this cyst usually presents a well-defined unilocular radiolucency attached to CEJ of an unerupted tooth which can cause displacement of adjacent tooth or resorption.
This article reports a large infected DC in a 10-year-old male patient related to first and second premolar maxillary teeth, which did not erupt or even change their positions. DC was treated successfully by decompression. After 2 years follow up, there was no evidence of recurrence. In conclusion, marsupialization of cyst with no orthodontic intervention or tooth extraction is a conservative, efficient protocol that stimulates bone healing and promotes the eruption of unerupted teeth even if they are deeply crowded.
