OBJECTIVE To determine the distribution of odontogenic cysts diagnosed histologically over a period of 38 years in a Brazilian population according to age, gender and site affected and to compare these data with previously reported studies from other countries. STUDY DESIGN A total of 1019 cases of odontogenic cysts diagnosed between 1970 and 2007 were studied. Clinical features obtained from...

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 ...

BACKGROUND This paper describes a quantitative analysis of the cyst lining architecture in radicular cysts (of inflammatory aetiology) and odontogenic keratocysts (thought to be developmental or neoplastic) including its 2 counterparts: solitary and associated with the Basal Cell Naevus Syndrome (BCNS). METHODS Epithelial linings from 150 images (from 9 radicular cysts, 13 solitary keratocyst...

Objective: To assess the thickness and color of collagen fibres in various odontogenic cysts for its possible role in expansion. Study design: 49 cases of 4 types of odontogenic cysts and 5 normal mucosal tissues were selected as the study and the control group respectively. All slides were stained with both Hemotoxylin and Eosin and the picrosirius red stain. The thickness of collagen fibres w...
