Estimation and correlative study of salivary nitrate and nitrite in tobacco related oral squamous carcinoma and submucous fibrosis.

[oral submucous fibrosis]

Oral cancer is one of the ten leading cancers of the world. In India, it is one of the common cancers and is an important public health problem. Tobacco plays significant role in etiology of oral squamous carcinoma. Tobacco which is chewed or smoked contains many alkaloids which are known carcinogens. Oral submucous fibrosis (OSMF) is a disease of the Indian subcontinent, which through immigration has a worldwide distribution. Betel nut chewing plays significant role in etiology of OSMF. The nut alkaloids have been shown experimentally to result in stimulation of collagen synthesis by fibroblasts in vitro, which can induce precancerous conditions.The present study was undertaken to detect nitrate and nitrite factor in saliva of cases with oral carcinoma, OSMF and normal individuals without any habits and to determine whether increased salivary nitrate and nitrite level is significant in oral carcinoma and submucous fibrosis using biochemical parameters.We conclude that the major inducer of oral squamous cell carcinoma (OSCC) is exposure to tobacco. Recent studies have demonstrated that oxidative and nitrosative stress contributes to the development of oral carcinogenesis through deoxyribonucleic acid (DNA) damage. Salivary composition of OSCC patients is substantially altered with respect to free radical-involved mechanisms.
