the term calcifying odontogenic cyst (coc) was first introduced by gorlin in 1962. coc occurs mainly as an intra-osseous lesion in mandible or maxilla but the peripheral variation of coc has also been reported. the confusion about coc nature as cyst or tumor has not been resolved and a vast diversity has been shown in clinicopathologic aspects of coc. the purpose of this study was the review an...

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...

Osteoporosis is a systemic disease in which the skeletal condition is characterized by a decreased mass of normally mineralized bone, due to an augmentation of bone resorption processes. Bone biomarkers serum are used for the diagnosis. On the other hand the main cause of the resorption in the bone jaws are periodontitis, inflammatory cysts, developmental cysts, odontogenic neoplasms. Periodont...

Orthokeratinized odontogenic cysts (OOCs) are relatively uncommon developmental cysts lined with orthokeratinized epithelium consisting of a prominent granular layer and a basal layer of low cuboidal flattened cells that show no tendency for nuclear palisading. These cysts have been considered a distinct entity from odontogenic keratocysts since they exhibit a less aggressive behavior and a ver...

BACKGROUND AND AIM: Intra-osseous pathologic lesions of the jaw bones have different radiological and clinicopathological features from benign to malignant lesions. The aim of this study was to determine the prevalence of jaw lesions in Isfahan, Iran, during 1992-2017. METHODS: In this descriptive-analytical study, all re...

Background: KAI-1/CD82 is a tumor suppressor gene with decreased gene expression being associated with increased invasive ability of Oral Squamous Cell Carcinoma (OSCC) and as hypothesised for various odontogenic cysts and tumors. p53 protein functions in G1-S phase of the cell cycle to allow the repair of damaged DNA. In the present study, p53 and KAI-1 expression was investigated by using mon...

Objectives: To focus on distribution of different histologic types of odontogenic cysts (OCs), patient gender and age, and cyst location in an Iranian population and compare results with others studies in different geographic locations and/or racial populations. Materials and Methods: A 40-year retrospective study of 1189 patients with OCs that were diagnosed from 1971 to 2011 in the Department...

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.
