AIM To determine the immunocytochemical pattern of expression of transforming growth factor (TGF) alpha, epidermal growth factor (EGF), and TGF beta in the three most common types of odontogenic jaw cyst. METHODS Growth factor expression was detected in paraffin wax sections of odontogenic cysts (27 odontogenic keratocysts, 10 dentigerous cysts, and 10 radicular cysts) using a streptavidin-bi...

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...

background and aims. the aim of this study was to investigate the relative frequency of developmental odontogenic cysts in an iranian population. materials and methods. in this study 245 cysts from both jaws, treated in the faculty of dentistry at tabriz university of medical sciences during a 10-year period from 1998 to 2008, were analyzed in order to evaluate the incidence of such cysts. we h...

BACKGROUND Cysts of the jaws constitute an important pathology in the oral and maxillofacial region and are broadly classified as odontogenic and non-odontogenic. Objective of this study was to document the clinical and radiographic presentation of odontogenic cysts at a tertiary care centre. METHODS In this descriptive case-series, patients presenting with features of suspected cystic lesion...

introduction calcifying odontogenic cyst (coc) is a unique and uncommon odontogenic cyst classified into four groups of cystic, odontoma producing, ameloblastomatous proliferating and neoplastic ones. case presentation a 34-year-old iranian man complaining of a painless facial and palatal swelling of the left side of the maxilla persisted for approximately three years was referred to the depart...

Orthokeratinized odontogenic cyst (OOC) is a developmental cyst that occurs in the jaw. it was initially defined by the world health organization as the orthokeratinized variant of odontogenic keratocyst (OKC). However, studies have shown that OOC has a peculiar clinicopathologic aspects when compared with other developmental odontogenic cysts, especially OKC's. The orthokeratinized odontogenic...
