Dentigerous cyst with ameloblastomatous proliferation as well as calcifications: An unusual presentation

Abstract

Dentigerous cyst is an odontogenic cyst that is of developmental origin associated with the crown of an impacted tooth usually the third molars and canines. This is one of the most common types of developmental odontogenic cysts. The prognosis of dentigerous cyst is excellent but this cyst might undergo neoplastic transformation into ameloblastoma/squamous cell carcinoma/mucoepidermoid carcinoma. In this case report, we have studied the lining wall of the dentigerous cyst which has shown ameloblastomatous transformation along with sporadic calcification in the deeper layers of the connective capsule. This type of calcification rarely occurs with the dentigerous cyst.
