Dentigerous cysts (DCs) are developmental cysts of odontogenic origin, which surround the crown of impacted or embedded teeth. The standard treatment for a DC is enucleation and extraction of the involved tooth. In large cysts, marsupialization is recommended to diminish the size of the osseous defect and to promote the eruption of the DC-associated teeth. However, cases reporting both of DC enucleation and preservation of the involved teeth are rare. This case report aimed to describe the management of an extensive DC in a 15-year-old Tunisian girl associated with the second right impacted premolar 15. The treatment instituted was cyst enucleation without extraction of the permanent teeth i.e we mixed both of the advantages of enucleation avoiding recurrence and marsupialization with preservation of the involved teeth. After one year of follow up, it positioned itself spontaneously without any orthodontic treatment.
