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...

Odontogenic cysts and tumors originate from remnants of odontogenic epithelium and have a wide spectrum of histopathologic and clinical characteristics, ranging from benign non-invasive to locally invasive or malignant lesions. Histopathologic similarities between these lesions may challenge the correct diagnosis, especially in small size specimens, and may also lead to unnecessary broad surger...

Odontogenic cysts, which showed cystic radiolucency in the jaw bone by radiographic examination and computed tomography, were enucleated by operation in 3 dogs. One dog had a odontogenic keratocyst in the incisive bone of the right maxilla and another 2 cases revealed dentigerous cysts in the mandible. These cyst walls were enucleated or transpired by semiconductor laser. Afterwards, osteogenes...

The aim of this study was to analyze the files of 695 consecutive patients operated on under general anesthesia for odontogenic cysts in an adult French teaching hospital for comparison with findings in world surveys. A retrospective survey of cysts of the jaws was undertaken at the Maxillofacial department, Pitié-Salpêtrière University Hospital, Paris, France. Data were retrieved from case not...
