Case report of dentigerous cyst of the lower incisor

ABSTRACT

This paper reviews the pathogenesis; clinical features and the behaviour of dentigerous cyst. A case of mandibular dentigerous cyst involving the incisor tooth (an unusual site) is presented to illustrate this pattern of behaviour. A recurrent pyogenic granuloma in the region of the lower incisors prevented the eruption of the lower left incisor with subsequent cystic formation around the tooth. The histological and radiological presentation is consistent with that of a dentigerous cyst. The significance of the potential of the cyst lining is stressed. The cyst was enucleated with the associated tooth as the latter was not in a favourable position to erupt. There was no recurrence after one year of treatment
