Comparison of total antioxidant capacity of saliva in men based on daily cigarette consumption
Objective: Antioxidants play an important role in inhibiting free oxygen and nitrogen radicals and preventing their formation. There are contradictory results regarding the relationship between cigarette smoking and total antioxidant capacity of saliva. In this study, the total antioxidant capacity of saliva has been compared in normal smokers, heavy smokers and non-smokers. Material and methods: In this cross-sectional study, 28 heavy male smokers (more than one pack of cigarettes per day), 28 normal male smokers (less than one pack of cigarettes per day), and 28 male non-smokers aged 25 to 40 years old entered the study. Unstimulated saliva was collected by Spitting method. The total antioxidant capacity of saliva was measured using Ferric Reducing Antioxidant Power Assay. Descriptive statistics, ANOVA, and Tukey tests were used to analyze the data. Results: The mean total antioxidant capacity of saliva in male non-smokers was 0.0598 ± 0.08 ?mol / L, in normal male smokers was 0.049 ± 0.04 ?mol / L, and in heavy male smokers was 0.0388 ± 0.035 ?mol / L, which did not show any significant difference between the groups (P > 0.05). Conclusion: The results of this study indicate that smoking does not have a significant effect on total antioxidant capacity of saliva in smokers.
