The pattern of distribution and expression of laminin and type IV collagen was studied in ten radicular cysts, ten dentigerous cysts and ten odontogenic keratocysts, by means of the streptavidin-biotin method. The purpose of this study was to investigate changes in the distribution of components of the basement membrane in an attempt to contribute to the understanding of the differences, as to ...

Odontogenic keratocysts (OKCs) are epithelial developmental cysts. It occurs Mainly in the second and third decades, with a slight predilection for males Usually, OKCs solitary lesions. They may occur mostly Mandible; most commonly posterior body Ascending ramus. Radiographically, present as A well defined radiolucent lesions smooth corticated margins. Multilocular or unilocular lesion. In of c...

Calcifying epithelial odontogenic tumors (CEOTs) and ghost cell odontogenic tumors (GCOTs) are characteristic odontogenic origin epithelial tumors which produce calcifying materials from transformed epithelial tumor cells. CEOT is a benign odontogenic tumor composed of polygonal epithelial tumor cells that show retrogressive calcific changes, amyloid-like deposition, and clear cytoplasm. Differ...

actinomycosis is an anaerobic infection that involves the craniofacial region and its colonization has rarely been reported in the developmental odontogenic cysts. in the present report, a case of odontogenic keratocyst (which is now called keratocystic odontogenic tumor) with the colonization of actinomyces is introduced and its significance is discussed.

This was a retrospective study of dentigerous cysts in people from the Singapore-Malaysian region. The purpose of this study was to present the clinicopathologic features of dentigerous cysts in the Oriental population and to compare these data with those from other reported studies. Biopsy records from 1981 to 1993 of 119 cases of dentigerous cysts from patients in Malaysia and Singapore showe...

Median palatine cysts are rare, non-odontogenic fissural cysts of the hard palate. These cysts occur in the midline of the hard palate, behind the incisive canal. Only two case reports have documented these cysts on multi-detector computed tomography (MDCT), neither giving detailed descriptions of the cysts. Knowledge of their existence is important and should not be confused with malignant tum...

The aim of this study was a comparative statistical analysis three categories maxillary odontogenic cysts, evaluating frequency in relation to localization (mandibular or region), age and gender patients. retrospective cohort conducted at the University Hospital Messina. Three hundred fifty-six cysts were classified into 283 inflammatory, 43 developmental 30 neoplastic cysts. Female patients ar...
