Convolutions of dentigerous cyst: An institutional experience

Statement of the Problem: Benign appearing dentigerous cyst (DC), also the most common developmental odontogenic cyst, shows various complications due to its pluripotent cell lining. The spectrum of diseases produced by conversion of its pluripotent cell varies from unicystic ameloblastoma, intraosseous epidermoid and central mucoepidermoid carcinoma. So, the need of the hour is to be acquainted with the etiopathogenesis of DC at molecular level and an attempt should be made to minimize its rate of tumor conversion.

To analyze the potential complications, their demographic profile, disease characteristics which can arise from the dentigerous cyst, and to be geared up for such situations in future.

Retrospective analysis was conducted and data was collected from the requisition forms during the time frame 2011- 2016 in the Department at Government Dental College, Haryana. Histopathologically diagnosed cases of dentigerous cyst were reviewed by three different observers and recorded, out of which DCs that showed potential complications were reviewed in detail.

Six cases of DC out of 26 showed transformation into central mucoepidermoid carcinoma, adenomatoid odontogenic tumor (two) and ameloblastoma (three) respectively.

The present research highlights the probable complications of DC encountered in our institute and conscientious vigilance should be exercised while histopathological examination of biopsied specimens. This study further unravels the enigma behind the emergence of neoplasms arising from DC.
