ABSTRACT
Orthokeratinized odontogenic cyst (OOC) is a relatively uncommon developmental cyst, thought to be arising from the cell rests of the dental lamina. Orthokeratinized odontogenic cyst (OOC) was first described by Schultz in 1927 and in 1945 Philipsen considered it to be a variant of Odontogenic keratocyst (OKC). OOC exhibits distinctive clinical, pathologic, and behavioral features that varied substantially from KCOT and hence now it is considered as a separate entity. We present a rare case of OOC occurring in a female patient which was attached to the lateral aspect of the root apex of the impacted third molar giving a false gross and radiographic appearance of lateral variant of dentigerous cyst.. The clinical, radiological, and histopathological features of this cyst and its surgical management are discussed.
Key words: Odontogenic keratocyst, dentigerous cyst, orthokeratinization, granular cell layer
