BACKGROUND Odontogenic cysts are those which arise from the epithelium associated with the development of teeth. Some odontogenic cysts were found to have special biological features that make them distinct from other lesions. This study was conducted to detect the immunoepxression of laminin-1 and Ki-67 in both radicular cysts (RCs) and keratocystic odontogenic tumors (KCOTs) and to examine th...

The cysts that originate in the remnants of dental lamina or enamel organ are known as odontogenic cysts. They are of great interest to otolaryngologists due to their proximity to the maxillary sinus and adjacent areas.1 Radicular cysts represent 72.5% of all odontogenic cysts, followed by dentigerous cysts (DC) (22.2%), and residual cysts (RC) (4.26%).2 The options for treatment of cystic lesi...

Sacral perineurial (Tarlov) cysts are rare lesions. Over a seven year period 4000 patients underwent surgery for lumbar disk herniation. In three patients neurological symptoms were caused by large sacral perineurial cysts. Methods of choice for diagnosis of Tarlov cysts are lumbosacral magnetic resonance imaging and computerized tomography myelography. The majority of Tarlov cysts are asymptom...

Among the odontogenic cysts, there are radicular cysts or also called periapical most common cyst. They develop at apex of a tooth with pulp necrosis, which may be consequence dental caries trauma. they asymptomatic, grow slowly, and discovered on routine radiographs. With proliferation ERM its activation, is an increase in osmotic pressure, causing cyst to expand, normally this not activated, ...

background and aims. accurate differential diagnosis between radicular cysts and periapical granulomas cannot be made from radiographs alone. histological prevalence studies, therefore, assume special importance and may aid the clinician in making judgments regarding therapy. the incidence of radicular cysts has ranged with wide discrepancies in data. the purpose of this study was to evaluate r...

Radicular cysts are the most common odontogenic cystic lesions of inflammatory origin which can be managed by marsupialisation specially if the cyst is large and is in relation to the vital structures. This article presents a case in which a radicular cyst was present in association with grossly carious deciduous molars and has been treated by marsupialisation. Postoperatively a surgical splint...

Odontogenic cysts of the jaws are one most common tumour-like neoplasms maxillofacial region in children. Today, there various methods treating cysts, but childhood, problem choosing a treatment method is relevant and at same time difficult, as some authors prefer cystectomy, while others cystotomy. Purpose - to analyze management jaw children depending on type cyst. Materials methods. A retros...

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...

BACKGROUND Interleukin-1 (IL-1) is one of the cytokines produced by macrophages, monocytes and dentritc cells. Macrophages are present in apical granuloma and the wall of the radicular cyst. This cytokine causes the cyst expansion and is involved in proliferation of fibroblasts in the cyst wall and stimulate the fibroblasts to produce more prostaglandin. Radicular cyst is the most common cyst o...
