Coincidence of nasopalatine duct cyst and dentigerous cyst: a rare case report

Abstract

Dentigerous cyst is one of the most common odontogenic cysts of the jaw that slowly grows around an unerupted tooth crown. Nasopalatine duct cyst is a non-odontogenic common jaw cyst. Co-oc- currence of nasopalatine duct cyst and dentigerous cyst in the same location of the same jaw is ex- tremely rare. Odontogenic and non-odontogenic cysts occurring simultaneously in non-syndromic patients is rare. The lesions must be fully extracted by surgery. We report the treatment procedure of a patient suffering from this rare phenomenon.
