Infected dentigerous cyst on a totally impacted mesiodens

Abstract

Dentigerous cyst is a developmental odontogenic cyst which originates through alterations of reduced enamel epithelium in an unerupted tooth or a developing tooth bud. These cysts rarely associate with supernumerary teeth. Supernumerary teeth accounts for 5% of all dentigerous cysts. The most common supernumerary teeth are mesiodens. The case study aimed to present a rare case of infected dentigerous cyst on a totally impacted mesiodens. This case report describes a rare case of infected dentigerous cyst associated with mesiodens in a 33 year old female who presented with a slow growing swelling in the palatal. Dentigerous cyst was treated with cyst enucleation with extraction of the mesiodens. Mesiodens should be diagnosed at the earliest possible time and its management should be conducted to prevent development of dentigerous cyst and damage to adjacent teeth and vital structures.
