ABSTRACT
Introduction - Chewing tobacco in different forms causes tooth decay. Coarse and hard particles from tobacco product may damage the enamel making teeth more prone to cavities. In long-term tobacco users the changes in saliva can render oral mucosa vulnerable to various oral and dental diseases. Aims & Objectives - To know the effect of tobacco chewing on the concentration of salivary calcium, phosphorus, and activity of alkaline phosphatase in dental caries. Material & Methods – Study includes 21 tobacco chewers having dental caries (Study group) and 117 caries free non tobacco chewers (Control group). Stimulated saliva was collected from all subjects and analyzed for estimation of salivary calcium, phosphorous, alkaline phosphatase activity. Results – Analysis of data showed significantly lower concentration of calcium (p<0.024) and phosphorous (p<0.000) in the study group than the control group. There is lowering activity of alkaline phosphatase in study group than control though the difference is not significant. Conclusion – Decreased flow rate of saliva in tobacco chewers, fermentation of food particles cause decrease in the pH of saliva which may diminish the activity of alkaline phosphatase. Lowering in the activity of salivary alkaline phosphatase may not release the phosphorous and calcium to compensate the demineralization.
Keywords: Salivary calcium, phosphorous, alkaline phosphatase, dental caries, tobacco chewers.
