Dentigerous cyst is a type of odontogenic cyst, characterized by a unilocular radiolucent lesion that encloses permanent tooth buds or, under certain circumstances, displaced tooth buds. 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.. The majority of these lesions are usually a radiological finding and are capable of quite large before being diagnosed. The standard treatment for these cysts is the enucleation and the extraction of the affected tooth. However, if the patient is a child and the affected tooth is not developed, a more conservative attitude should be considered. This case report presents a mandibular dentigerous cyst in a 10-year-old boy. Marsupialization was the treatment of choice and orthodontic correction was provided. Long-term follow-up revealed good healing of the bony lesion. Keywords: Dentigerous cyst, Enucleation, Marsupialization, Decompression.
