Orthokeratinized Odontogenic Keratocyst: Report of Nine Cases with Review of Literature.

Formerly believed to be a subtype of odontogenic keratocyst (OKC), orthokeratinized odontogenic cyst (OOC), a rare developing odontogenic cyst, is now believed to be distinct. The clinical, radiographic, histological data are included in this report, along with a review of the literature to aid in comprehending the cyst. A retrospective search in the oral pathology department between 2018 and 2022 was conducted to recover all cases reported as OOC in SRM Dental College, Ramapuram. Radiographs and Haematoxylin and Eosin stained histological slides were re-examined. Overall, there were nine cases in which men were engaged in 80% of the instances and the group's ages varied from 20 to 35. The primary symptoms of all of the patients were pain and edema. The vast majority of cases had an impacted tooth in the jaw. All of the lesions showed clearly visible radiolucency on orthopantomographs [OPG], with the exception of one specific case. Additionally, histological examination of each patient revealed the characteristic microscopic traits and enucleation was done to treat all the cases. OOC has a more favourable outcome than OKC due to variations in prognosis, management and must be considered distinct from OKC. Most of our cases-a large majority-involved adolescent males' mandibles and involved pain and edema. Most were unilocular and all were radiolucent. The literature-recommended histopathological findings were present and all cases were enucleated.
