Abstract
Odontogenic keratocyst (OKC) is an aggressive odontogenic lesion that has been the subject of continuous dispute about its biological activity and classification. 'Numerous studies are being conducted to see how much more or lower expression of the tumour-suppressing p53 protein is in the odontogenic cyst than in the dentigerous cyst (DC) or ameloblastic tumours. The aim was to find immunohistochemistry studies reporting on OKCs, DCs and ameloblastomas (AMBs); we searched MEDLINE, WEB of Science and SCOPUS. Effects may be shown to exist when the risk difference (RD) between lesions overexpressing and those without the p53 protein was a P value of less than 0.05. A total of 129 records were returned in the first hit. After the elimination of duplicates, there were 89 items, of which 18 were deemed eligible for inclusion. According to a meta-analysis of 13 studies including OKCs, DCs and AMB, the chance of p53 expression in OKCs is assessed to be 23 per cent higher (P = 0.003) than in DCs, whereas the probability is predicted to be 4 per cent lower (P = 0.028) than in AMBs. OKCs appear to act more like cancers than odontogenic sores as far as p53 articulation, and the order of this illness into the keratocystic odontogenic tumour (KCOT) ought to be rethought.
