BACKGROUND Odontogenic cysts are defined as those cysts that arise from odontogenic epithelium and occur in the tooth-bearing regions of the jaws. Cystectomy, marsupialization or decompression of odontogenic cyst are treatment approach to this pathology. The aim of this study was to evaluate the effectiveness of the decompression as the primary treatment of the cystic lesions of the jaws and th...

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...

Cement-osseous dysplasia is a disease of localized fibrotic connective tissue proliferation accompanying cementum or bone-like hard at the tooth apex, while simple bone cyst specific featuring cavity without epithelial lining. Here, we report case cement-osseous associated with multiple cysts resembling cavities. A 60-year-old woman was referred to our hospital due complaint recurring pain and ...

Tarlov (perineural) cysts of the nerve root are common and usually incidental findings during magnetic resonance imaging (MRI) of the lumbosacral spine. There are a few case reports where symptomatic thoracic perineural cysts have been described in the literature. We report a case of a high thoracic nerve root perineural cyst that failed conservative therapy, requiring surgical intervention. Ou...

Separate antisera were raised against keratocyst, dentigerous cyst, and radicular cyst fluids and used to analyse a range of fluids from cysts of known type. Samples were subjected to crossed immunoelectrophoresis into homologous antiserum through an intermediate gel containing antibody to whole human serum to screen out serum derived components. A major antigen, designated X, which seems to be...

Purpose: Odontogenic cysts and tumors comprise a major component of lesions the oral maxillofacial region. The pathogenesis these involves interaction between odontogenic epithelium ectomesenchyme. However, clinical behavior biological entities is unpredictable. aim this study was to evaluate role Cyclooxygenase 2 (COX-2) in prognostication lesions.Material method: : In formalin-fixed paraffin-...

Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare lesion that almost exclusively occurs in the jaws. Most PIOSCCs originate from epithelial lining of odontogenic cysts, especially from radicular, residual, and dentigerous cysts. A few cases have been shown to arise from keratocystic odontogenic tumors (KCOTs). This is a report of a case of PIOSCC that arose from an untreated kerat...

The presence of perineural cysts within the sacral spinal canal was initially described in the literature as early as 1938, when Tarlov had identified a similar lesion during one of his autopsies [1]. These rare cerebro-spinal fluid-filled lesions arising from the nerve root sheaths of the dorsal root ganglion, have thence, been described by various authors with diverse clinical and radiologica...

Introduction: The development of radicular cysts in primary dentition is an unusual occurrence. A relation with pulp treatments has been reported and represent issue to be considered on follow up. Case description: seven-year-old female child had a necrosed mandibular right second molar pulpectomized zinc oxide eugenol paste. At the nine-month radiographic evaluation, there was image compatible...
