Cytokeratin 19 Expression Patterns of Dentigerous Cysts and Odontogenic Keratocysts
BACKGROUND Although numerous investigators have studied the pattern of keratin expression in different odontogenic cysts, the results have been variable. AIM The present study was conducted to determine the pattern of expression of cytokeratin 19 (CK 19) in the epithelial lining of odontogenic keratocysts and dentigerous cysts. MATERIALS AND METHODS The epithelial layers showing expression ...
متن کاملExpression of Matrix Metalloproteinases 2 and 19 in Odontogenic Keratocysts and Dentigerous Cysts
Background and Aim: Odontogenic keratocyst (OKC) and dentigerous cyst (DC) are two common developmental cysts involving the jaws. The role of matrix metalloproteinases 2 (MMP2) and 19 (MMP19) in progression and invasion of some cysts and tumors has been documented. This study sought to assess the expression of MMP2 and MMP19 in OKCs and DCs. Materials and Methods: In this descriptive analyti...
متن کاملExpression of cytokeratin in the epithelium of dentigerous cysts and odontogenic keratocysts: an aid to diagnosis.
Sections of tissue embedded in paraffin wax from 18 selected odontogenic cysts were studied both histologically and immunohistochemically with antibodies to cytokeratins using the indirect peroxidase technique. The cysts were divided on a clinical and histological basis into two equal groups comprising dentigerous cysts and odontogenic keratocysts. It was possible to differentiate the two cyst ...
متن کاملOdontogenic Keratocysts: a Clinical and Radiographic Study
This descriptive study was carried out, at Khyber College of Dentistry, Peshawar from Sept 2005 to Jan 2007, on 40 patients having histopathologically confirmed odontogenic keratocysts.. Maximum patients (62.5%) presented in the 2nd and 3rd decades. 21 were male while 19 were female. Seventy five percent cases occurred in the mandible, with the posterior region involved in maximum number of cas...
متن کاملAngiogenesis: A Critical Role in Locally Aggressive Behavior of Keratocystic Odontogenic Tumor
Introduction: Odontogenic cysts are osteodestructive lesions affecting the jaws. Odontogenic keratocyst is an odontogenic cyst with highly aggressive features. Multicystic ameloblastoma is a benign epithelial odontogenic tumor with more aggressive behavior than dentigerous cyst and odontogenic keratocyst. Invasion and metastasis of tumors require increased blood vessels during tumorigenesis. Th...
متن کاملExpression of Epidermal Growth Factor Receptor by Odontogenic Cysts: A comparative Study of Dentigerous Cyst and Odontogenic Keratocyst
Abstract: Background and Aim: Compare with Dentigerous cyst, Odontogenic Keratocyst is one of exclusive developmental cyst with unique clinical and histopathologic features. Considering the determining role of epidermal growth factor receptor (EGFR) in cell proliferation and survival, and the controversial results of previous studies regarding the expression of this marker by the odontogenic cy...
