Dentigerous cyst as mid palatal swelling : a case report.

ABSTRACT

Dentigerous cyst is a developmental odontogenic cyst which originates through alterations of the reduced enamel epithelium in an unerupted tooth after the crown has been fully formed. Dentigerous cysts associated with supernumerary teeth are rare and constitute 5–6% of all dentigerous cysts. Supernumerary teeth should be examined very carefully to prevent possible effects on adjacent regular teeth and possible cystic development. We report a rare case of mid palatal swelling due to a dentigerous cyst associated with an impacted supernumerary in an elderly patient.
