Abstract

Dentigerous cyst is one of the common odontogenic cysts and they are associated with unerupted or impacted teeth. However, multiple dentigerous cysts are rare and they are usually associated with syndromes such as basal cell nevus syndrome, mucopolysaccharidosis (type VI) or cleidocranial dysplasia. Very few cases of multiple dentigerous cysts involving first permanent molars are reported. This report is of a rare case of bilateral dentigerous cyst involving mandibular first molars in a non- syndromic 7 year old male patient. A provisional diagnosis of a dentigerous cyst was given based on clinical finding of missing 36 and 46 with buccal cortical plate expansion and presence of a pericoronal radiolucency attached to the CEJ irt to 36 and 46 on panoramic image. The computed tomographic finding revealed a well defined expansile cystic lesion in right and left mandibular molar regions. Enucleation of the cyst with extraction of 36 and 46 was done and the specimen was sent for histopathological examination which confirmed the diagnosis of dentigerous cyst.
