Background: The most addictive constituent of tobacco is the alkaloid nicotine. Nicotine is said to have a considerable influence on the level of lipids in blood. Several studies have stated that alterations in lipid profile have been associated with development of OC and other premalignant lesions/conditions. Very little literature is available on lipid profile alterations at an early stage, i...

The betel nut (Areca catecu) is regarded by the World Health Organization as the fourth most prevalent human carcinogen. Our study aims to investigate whether habitual chewers show bias in their attention toward betel nut usage. In the current study, heavy and light betel nut chewers were instructed to respond to a probe presented immediately after either one of a pair of areca-related picture ...

This study was designed to investigate the association between long-term regular khat chewing and self-reported oral symptoms. METHODS A cross-sectional study was conducted on a sample of 1,255 university students in southern Ethiop...

OBJECTIVE To isolate, culture and characterize fibroblasts from the buccal mucosa of areca nut chewers with and without oral submucous fibrosis (OSF). MATERIALS AND METHODS Primary fibroblast cultures were established by the collagenase disaggregation technique and the phenotypic and growth characteristics were studied. RESULTS Cells cultured from OSF showed a statistically significant incr...

In the present study, variation among different bacterial strains was observed in the plaques of tobacco chewers (TC) as compared to those from normal persons (non tobacco chewers) (NTC). Bacterial strain J1 (dominant in the plaques of NTC) did not initiate the process of adhesion (biofilm formation) until it appeared to have reached a required population density necessary for the production of...

Oral premalignancies are also very common in betel quid chewers and about 10% of these undergo malignant transformation. Although education for cessation of the betel quid chewing habit is important, there are few adequate strategies and policies for primary prevention, health promot...
