BACKGROUND The aim of this study was to determine the range of all histologically diagnosed odontogenic cysts along with age range, sex distribution and site of presentation over a 30-year period. METHODS All entries for odontogenic cysts occurring during 1975-2004 inclusive were retrieved and analysed for demographic data. RESULTS A total of 55,446 specimens were received, of these 7121 (1...

STATEMENT OF THE PROBLEM Odontogenic cysts and tumors are the most frequent osseous destructive lesions of the jaws; however, there is little information regarding the relative frequency of these lesions among the Iranian population. PURPOSE The purpose of this study was to determine the distribution of clinically and histologically- diagnosed odontogenic cysts and tumors during a period of 1...

OBJECTIVE The aim of this study is to evaluate the caveolin-1 expression in a group of odontogenic cysts and tumors. MATERIAL AND METHOD In this cross-sectional study, the expression of caveolin-1 was evaluated immunohistochemically in 75 samples including 18 cases of dentigerous cyst, 18 odontogenic keratocysts, 3 orthokeratinized odontogenic cysts, 2 calcifying odontogenic cysts and 34 amel...

Dentigerous cysts are developmental odontogenic jaw cysts, commonly manifesting in the second and third decades of life. Very few of these cysts have been reported in children younger than 10 years of age. This article describes a rare case of dentigerous cyst in a 1-year-old boy, the youngest case to be documented. The clinical, radiographic and histopathologic features are discussed; the incr...

BACKGROUND AND OBJECTIVE: Glandular odontogenic cyst is a rare developmental odontogenic cyst which most frequently occures in mandible. According to low incidence and unusual shape and location of this case, we decided to report the case. CASE REPORT: Here we present an asymptomatic case in anterior part of maxilla that  radiographically was small and unilacular mimicking as a nasopalatine du...

Odontogenic keratocysts (OKCs) are developmental cysts which occur typically in the jawbones. They present more commonly in the posterior mandible of young adults than the maxilla. OKCs have been reclassified under odontogenic tumours in 2005 by the WHO and have since been termed as keratocystic odontogenic tumours (KCOTs). Here we report a case of a recurrent buccal lesion in a 62-year-old man...

The purpose of this study was to evaluate the prevalence of 680 odontogenic cysts diagnosed in Porto Alegre, RS, Brazil, and to compare results with findings in the literature. Data of odontogenic cysts diagnosed from 1985 to 2005 were collected from the files of the Oral Pathology Laboratory of Pontifícia Universidade Católica do Rio Grande do Sul, Porto Alegre, RS, Brazil, and entered in a st...

Background & Objectives: Odontogenic cysts are among the most frequent destructive lesions of jaws which their pathogenesis and growth mechanism are not cleared. With respect to different roles of mast cells, they may play a role in the pathogenesis and growth of odontogenic cysts. The aim of present study was to evaluate mast cells in the most common odontogenic cyst. Methods:</e...

background. the aim of this study was to investigate myofibroblast (mf) density in a broad spectrum of odontogenic cysts and tumors and the relation between the density of mfs and the clinical behavior of these lesions. methods. a total of 105 cases of odontogenic lesions, including unicystic ameloblastoma (uam), solid ameloblastoma (sa), odontogenic keratocyst (okc), dentigerous cyst (dc), rad...
