SPECIFIC ASPECTS OF ORAL FLUID COMPOSITION OF SMOKERS

Resume. The condition of the oral mucosa, gums and periodontal tissues is largely determined by the quantity and quality of the oral fluid content. Many researchers have noted quantitative and qualitative changes in saliva in chronic tobacco intoxication. Thus, when smoking, there is an increase in the concentration of excess nitrites and thiocyanate in mixed saliva. When smoking, the concentration of thiocyanate in the blood serum is 2-3 times higher than its normal values. Thiocyanate is considered a strong catalyst of endogenous nitrosation of amines, in which process carcinogenic nitrosamines are formed. The presence of thiocyanate in saliva accelerates the nitrosation process
