Radicular cysts are the most common cystic lesions affecting the jaws. They are most commonly found at the apices of the involved teeth. This condition is usually asymptomatic but can result in a slow-growth tumefaction in the affected region. The following case report presents the successful treatment of radicular cysts using autologous periosteum and platelet-rich fibrin with demineralized fr...

The purpose of this report is to document a case of unsuspected ameloblastoma involving the right man dibular subpontic region in a 38-year-old Cambodian female patient. This lesion was purportedly preceded by multiple radiolucencies which were diagnosed as radicular cysts and treated a few times in the past years by enucleation followed by endodontic therapy of the affected teeth. Bridgework r...

Glandular odontogenic cyst (GOC) is an uncommon developmental cyst. It accounts for 0.012% to 1.3% of all the jaw cysts; its prevalence is 0.17%. It was described by Gardner et al. in 1988 as a distinct entity. GOC has a slight predilection for mandible and affect more commonly in the middle-aged patients. Radiographic and clinical features of this cyst are not pathognomonic or specific. Only t...

Correspondence to: Luís Monteiro Rua António Moreira da Silva, 175 4475-457 Maia Portugal E-mail: [email protected] Abstract Odontogenic cysts are lesions that deserve every attention, mainly because of all complications they can cause. To study their characteristics, the authors did a retrospective clinicopathological analysis of 124 oral biopsies that were diagnosed as odontogenic cyst...

OBJECTIVE The present study investigated the expression of p53 protein and iNOS in odontogenic keratocysts (OKCs), dentigerous cysts (DCs) and radicular cysts (RCs) and determined the correlation of these 2 proteins within each cyst type. MATERIAL AND METHOD p53 and iNOS in epithelial lining cells were analyzed in 20 OKCs, 20 DCs and 20 RCs using immuno-histochemistry. The percentage of posit...

The maxillofacial region is affected by a greater number of cysts than any other part of the body. In this study, 90 odontogenic cysts were collected from 90 patients over a five-year period. Patients with radicular cysts, dentigerous cysts and odontogenic keratocysts were further analyzed with regard to age, sex and anatomical distribution. Using the histological classification of the World He...

Activation of the epithelial cell rests of Malassez by various means, results in proliferation of these cells and formation of apical periodontal cysts. Several theories for the genesis of apical periodontal cysts have been suggested which are not satisfactory. Available evidence indicates that development and destruction of these lesions are mediated by immunological reactions.
