The purpose of this study was to determine the prevalence of odontogenic cysts at the Pernambuco School of Dentistry - Universidade de Pernambuco (Brazil) and compare this prevalence with other international studies. Data for the study were obtained from reports of patients diagnosed with odontogenic cysts between 1992 and 2007. Case records of patients who fit the Histological Classification o...

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...

Among cysts of inflammatory origin, radicular and follicular are most often found in children. Follicular with a frequency 35.5-42% among all odontogenic between the ages 7 14 years. It was that localization cyst depends on age: children, lower premolars (20.8%) upper canines (10%) more causal, adults, third molars (23.3%) (18.3 %). Cysts from rudiments deciduous teeth quite rare [1].

OBJECTIVES To determine the relative incidence of odontogenic cysts and to identify the main clinicopathological features among patients treated in the Oral Surgery Department of the Dental Clinic of the University of Barcelona (Spain). STUDY DESIGN A retrospective observational study was made of 418 odontogenic cysts diagnosed in 380 patients included in the database of 1235 histopathologica...

The lining of an odontogenic cyst may show potential for neoplastic transformation to non odontogenic malignancies like squamous cell carcinoma and mucoepidermoid carcinoma and also odontogenic tumors like ameloblastoma and adenoamatoid odontogenic tumor (AOT). Unicystic ameloblastoma is a single cystic cavity lesion which shows ameloblastomatous differentiation in the lining. The clinical and ...

AIM To present the clinicopathological features of a series of four periapically located central giant cell granulomas (CGCGs) that were misdiagnosed and treated as being of endodontic origin. SUMMARY Four cases of periapical CGCGs were submitted with a clinical diagnosis of either radicular or residual cyst. In two cases, root canal treatment had been performed previously. The patients were ...
