BACKGROUND Odontogenic cysts (OC) are the most frequent lesions of the jaws and their constant epidemiological update is necessary and indispensable. Therefore the principal objective of this report was To determine prevalence and clinical-demographical characteristics of OC in a Mexican sample. MATERIAL AND METHODS 753 cases of OC coming from the archive of a head and neck histopathological ...

p53 and pcna expression in keratocystic odontogenic tumors compared with selected odontogenic cysts summary: the aim of this study was to evaluate p53 and pcna expression in different odontogenic lesions regarding their different clinical behaviors. slices prepared from 94 paraffin-embedded tissue blocks (25 radicular cysts (rc), 23 dentigerous cysts (dc), 23 keratocystic odontogenic tumors (kc...

introduction calcifying odontogenic cyst (coc) is an uncommon odontogenic lesion, classified in two variants: the cystic variant and neoplastic (solid) variant. case presentation this case report presents multiple coc, which involved the maxillary bone and sinus in a 30-year-old man. several of these lesions were cystic, while the others were neoplastic in type, and the lesions were removed sur...

although aneurysmal bone cysts and calcifying odontogenic cysts accompanied with other lesions are reported in the literature, the simultaneous occurrence of these two distinct lesions has not been reported. to the best of our knowledge, this is the first report describing co-occurrence of these two lesions located in the left mandibular ramusin a 36-year-old woman.

The aim of this study is to investigate the proliferative potential of rests of odontogenic epithelium found in follicles of unerupted teeth, epithelium of oral mucosa and epithelial linings of various odontogenic cysts. MIB-1 expression was studied in the rests of odontogenic epithelium (n=10), healthy oral mucosa (n=10), odontogenic keratocysts (n=10) and other odontogenic cysts (n=10) using ...

Odontogenic keratocyst (OKC) accounts for 3-11% of all odontogenic cysts. OKC is a benign intra-osseous tumor, but what makes this cyst special its aggressive behavior and high recurrence rate. relatively compared to other cysts, malignant transformation considered extremely rare. Squamous cell carcinoma associated with keratocysts have rarely been reported in the medical literature. We recentl...

abstract introduction. p53 has been known as a tumor suppressor gene and also ki-67 is a cell cycle regulator. the aim of present study was to investigate p53 and ki-67 protein expression in the epithelial lining of odontogenic cysts and its correlation with their biologic behavior and the degree of inflammation within the cyst wall. methods. p53 and ki-67 immunoreactivity in 58 odontogenic cys...

A survey of oral biopsies performed in an oral surgical centre in Singapore from 1993 to 1997 was carried out to determine the relative frequency of oral pathologies encountered. A total of 2057 reports were reviewed, of which 1986 separate diagnoses were counted. The great majority of patients were Asian. The 20 most common diagnoses were: fibrous epulis (10.3%), periapical granuloma (8.8%), m...
