Data was analyzed using descriptive and analytical statistical methods and SPSS.16 software.Īverage total antioxidant capacity in smokers' saliva was 1.87 ± 0.49 mol/dL and the mean vitamin C was 1.60☐.30 mg/dl. These antioxidants are as follows: total antioxidant, Vit.C. Then the levels of salivary antioxidants in smokers and non-smokers were assessed separately. In this descriptive analytical study that was done in Tabriz, 5 ml unstimulated saliva by spitting method from 50 smokers and 50 healthy non smokers was collected. With consideration of the importance of saliva and it`s defense system such as antioxidants and minerals in creation of different disease and destructive effects of cigarette smoking and lack of researches about this topic, we have assessed the effect of cigarette`s smoking on saliva`s antioxidants. Decreased antioxidant`s level can be one of the etiologic factors of oral Mucosal lesions. Few studies have shown the role of oxidative stresses in smokers. The aim of this study was to evaluate salivary antioxidant`s levels in smokers in comparison to non-smokers.
