The Effect of Smoking on Mineral and Protein Compositionof Saliva

INTRODUCTION To assess the salivary composition of proteins and minerals in smokers compared with non-smokers. MATERIALS AND METHODS In this study we compared the total protein and Ca, Na, K, Mg, Pb of whole saliva in two groups of men (28 smokers and 31nonsmokers) aged between 29-41years. RESULTS Fifty-nine participants were evaluated. The mean age was 33.14±5.32 years among smokers and 32.15±5.12 years among non-smokers (P>0.05). The mean concentration of total protein, Ca, Pb, and Zn of whole saliva in smokers was lower than that in non-smokers, but the difference was not statistically significant (P>0.05). The mean concentration of Na, K, Mg in whole saliva was not significantly different between smokers and non-smokers (P>0.05). CONCLUSION We specified that smoking reduced the value of total protein, Ca and Pb of saliva, however it did not have an impact on Na, K, and Mg of saliva.
