Odontogenic keratocyst mimicking dentigerous cyst: A case report

Impacted mandibular third molars are commonly associated with pericoronal radiolucencies. Dentigerous cysts is the most common developmental cyst of the jaw. Ameloblastoma, Dentigerous cyst and Odontogenic keratocyst have similar clinical and radiographic features but they differ in histopathological features and treatment modalities. This article presents the case of a 35year old male patient with complaint of mild pain and swelling, posteriorly in mandibular right quadrant. On clinical and radiographic examination the diagnosis was Dentigerous cyst but on aspiration cytology it was suggestive of Odontogenic keratocyst. Pericoronal radiolucencies are relatively common in most cases related to impacted mandibular third molars therefore it should be carefully evaluated with respect to clinical, radiographic and histopathological aspects.
