Abstract

The Dentigerous cyst is reported to be one of the most common lesions of the jaw. It is derived from reduced enamel epithelium that surrounds the crown of an unerupted tooth. Dentigerous cysts usually remains asymptomatic and presents as well-circumscribed radiolucencies surrounding the crown of a tooth. Most dentigerous cysts are treated by surgical enucleation or marsupialization of the cyst to allow eruption of the permanent tooth. The nasopalatine duct cysts derived from the islands of epithelium remaining after closure of the embryonic nasopalatine duct. The cyst presents as a well-circumscribed oval or heart-shaped radiolucency located in the midline of the anterior maxilla between the roots of the central incisors. Treatment is by surgical enucleation, employing a palatal approach. This report present two cases. One case was diagnosed with dentigerous cyst and treated by enucleation. 12 Months later, affected second premolar was erupted normally. The other case was diagnosed with nasopalation duct cyst. Histological examination of the enucleated cyst confirmed a nasopalatine duct cyst. There was no recurrence during follow up period.
