AIMS Prolonged production of the free radical, nitric oxide (NO) by the enzyme inducible nitric oxide synthase (iNOS) plays an important role in tumour progression by promoting angiogenesis, invasion and inducing mutation in tumour suppressor gene. The purpose of this study is to evaluate the expression and intensity of iNOS in normal oral mucosa, precancer(More)
Central odontogenic fibroma (COF) is an uncommon tumor that accounts for 0.1% of all odontogenic tumors; it has been defined as a benign neoplasm of the jaw. Clinically, the lesion grows slowly and leads to cortical expansion. Radiologically, the most common finding is multilocular radiolucency. The lesions are associated with the crown of an unerupted(More)
CONTEXT Inducible nitric oxide synthase (iNOS) is a cytoplasmic enzyme which plays a crucial role in the pathogenesis of oral carcinomas and sarcomas. AIMS The objective of this study was to analyze the immunohistochemical expression of iNOS in carcinomas and sarcomas affecting the oral cavity in order to understand the possible role of iNOS in their(More)
Odontomas are hamartomatous malformations of odontogenic origin. During tooth developmental stages any defect in the maturation phase of morpho-differentiation leads to such anomalies. Odontomas are benign, slow-growing and nonaggressive clinically asymptomatic and are diagnosed on routine radiological examination. In our case report an asymptomatic hard(More)
