ORTHOKERATINIZING ODONTOGENIC CYST: CLINICAL FEATURES, RADIOLOGY AND HISTOPATHOLOGY
Author: Sanketh DS, MDS
Orthokeratinized odontogenic cyst (OOC) was first described as an orthokeratinizing variant of odontogenic keratocyst (OKC) in 1981. The basis of this distinction was the difference in its histopathology and its reduced chances of recurrence as compared to OKC, although it was not given the status of a distinct odontogenic cyst. Later in 2005, OKC was classified as a tumor considering its aggressive behaviour and growth potential, and was renamed keratocystic odontogenic tumor (KCOT). However OOC was not considered to be a part of the tumor spectrum of KCOT.
