. Orthokeratinized Odontogenic Cyst OOC is a rare developmental odontogenic cyst which was considered in the past to be a variant of keratocystic odontogenic tumor KCOT. In 1981 Wright identified it owing to its different histology and relatively low recurrence rate as Orthokeratinized variant of odontogenic keratocyst OKC. A clinicopathologic study of 159 cases and molecular evidence for the absence of PTCH1 mutations.
Orthokeratinized odontogenic cyst OOC is an odontogenic cyst was initially termed as the uncommon orthokeratinized type of odontogenic keratocyst by the World Health Organization. The databases searched were the PubMed interface of MEDLINE and LILACS. The orthokeratinized odontogenic cyst OOC is a rare developmental odontogenic cyst that has been considered as a variant of the keratocystic odontogenic tumour KCOT until Wright 1981 defined it as a different entity.
Only those reports of OOCs that occurred. Journal of Contemporary Dentistry 2012. All cysts were treated by enucleation or enucleation after decompression.
To demonstrate the clinicopathological and radiological features of orthokeratinized odontogenic cysts OOCs and analyze the epithelial cell proliferative activity between OOCs and odontogenic keratocysts OKCs. Author links open overlay panel Qin Zhou a 1 Ling Xu b 1 Hui Li a Rong-Hui Xia c. Clinicopathological and radiological analyses were performed in all OOC cases.
Clinicopathological and radiological features of a series of 48 Cases. However they have been redefined as a distinct entity. Orthokeratinized Odontogenic Cyst OOC is a rare developmental odontogenic cyst which was considered in the past to be a variant of Odontogenic keratocyst OKC later renamed as keratocystic odontogenic tumor KCOT.
The expression of cell proliferation markers Ki-67. The aims of the review were to evaluate the principal clinical and conventional radiographic features of orthokeratinized odontogenic cyst OOC by systematic review SR and to compare the frequency of OOC between four global groups. The average follow-up time was 32502758 months ranging from 6 to 65.
However there had been controversy because the histological and clinical features. It usually occurs in mandible. Orthokeratinized odontogenic cyst OOC is a rare developmental odontogenic cyst characterized by orthokeratinized stratified squamous epithelial lining.
The aim of this study was to report a large series of OOC to substantiate its clinicopathologic profiles and to investigate PTCH1 mutations in OOCs. OOC should be histopathologically differentiated from OKC which has a higher recurrence rate and lower malignant potential. Orthokeratinized odontogenic cyst OOC is a developmental cyst of odontogenic origin and was initially defined as the uncommon orthokeratinized variant of odontogenic keratocyst OKC.
Orthokeratinized odontogenic cyst OOC is an uncommon odontogenic cyst. Orthokeratinized odontogenic cyst OOC a newly designated entity of odontogenic cysts is an intraosseous jaw cyst that is entirely or predominantly lined by orthokeratinized squamous epithelium. A benign developmental odontogenic cyst mostly unilocular with a fibrous tissue wall lined predominantly or entirely by orthokeratinized stratified squamous epithelium Essential features Cystic bone lesion in mandible or maxilla with compatible radiological features.
These cysts were originally classified as a subtype of odontogenic keratocysts. OOCs were first described in 1927 by Schultz 2 as a variant of odontogenic keratocysts now known as keratocystic odontogenic tumours KCOTs 3. It has been categorized as a subtype of odontogenic keratocyst OKC.
OOC has been designated as a dis- choice for OOCs and DCs. In 2005 it was classified as a distinct entity. Orthokeratinized odontogenic cysts are a rare type of odontogenic cyst which are identified by an orthokeratinized stratified squamous epithelium.
1 In 1981 it was Wright who specified its clinicopathological aspects and suggested that it be called odontogenic keratocyst- Orthokeratinized variant2 With the new World Health. The treatment of OOC is by enucleation and the prognosis following enucleation is excellent with a recurrence rate of less than 2. Orthokeratinized odontogenic cyst OOC.
Surgery is the usual treatment and recurrence or association with Gorlin-Goltz syndrome has rarely been described. OOC had been previously coded as odontogenic keratocyst OKC and was termed as orthokeratinized variant of OKC. Orthokeratinized odontogenic cyst OOC is a rare intraosseous cyst characterized by an orthokeratinized epithelial lining and minimal clinical aggressiveness.

Orthokeratinized odontogenic cyst OOC is a relatively uncommon developmental cyst comprising about 10 of cases that had been previously coded as odontogenic keratocysts OKCs16 In 1981 Wright2 reported 59 cases of what he then termed orthokeratinized variant of OKC which showed little clinical aggressiveness.
