“…The present study is consistent with the results of previous studies. 3,15,16 The elevated levels show the defensive system of the body occurring to reduce the free radicals produced by cigarette. GSH-Px acts as a powerful antioxidant defense system in our body, which converts H 2 O 2 produced by SOD into nonharmful molecular oxygen and water.…”

Background: Cigarette smoke contains various oxygen-free radicals which are considered as the main causes of damage to biomolecules when exposed to cigarette smoke. Saliva is the first biological fluid that encounters inhaled cigarette smoke (CS) and has an antioxidant defense system able to counter toxic activities of free radical species. So, the aim of this study was to compare the levels of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in saliva of smokers and nonsmokers.

Background and aims. Cigarette smoke can induce oral cancer by its free radicals and oxidative damage. Salivary anti-oxidants system is believed to have an important role in defense mechanisms against oxidative stress. This study was compared total antioxidant capacity (TAoC) of saliva in smokers and nonsmokers.Materials and methods. In this cross-sectional study, 30 male smokers with mean age of 45.23 years and 30 nonsmokers with mean age of 45.30 years participated. Unstimulated whole saliva samples were collected in the morning in two groups by spitting method. TAoC of saliva was measured with the special kit in two groups at the same time. Statistical analysis was performed by covariance test.Results. The mean salivary TAoC in nonsmokers (0.741±0.123 U/ml) was higher than that in smokers (0.529±0.167 U/ml). This difference was statistically significant (P<0.001).Conclusion. Smoking can alter salivary antioxidant capacity.

“…Antioxidant system of the body is attached by the cigarette smoking. [7][8][9] Literature quotes paucity in data, highlighting the changes occurring in antioxidative levels in smokers. Hence, we planned the present study to evaluate the impact of cigarette smoke on salivary antioxidant levels and cotinine levels in smokers and nonsmokers.…”

Introduction:One of the common practices observed in many parts of the world is smoking, of which tobacco forms an important constituent which is burned and inhaled. Smoking is known to have potential effect on body's immune system, antioxidants level, and salivary cotinine levels. Hence, we planned the present study to evaluate the impact of cigarette smoke on salivary antioxidant levels and cotinine levels in smokers and nonsmokers. Materials and methods:The present study included assessment of salivary parameters of smokers and nonsmokers. A total of 400 subjects were analyzed, of which 200 were active smokers and 200 were nonsmokers. Unstimulated salivary samples were taken and assessment of α-amylase levels was done using biochemical kit and spectrophotometer. Assessment of salivary catalase (CAT) activity was done using Luck method. For the determination of cotinine levels, Bioassay Technology Laboratory kit was used using enzyme-linked immunosorbent assay (ELISA) technique. After the assessment of levels of all the salivary parameters, all the data were recorded, compiled, and analyzed.Results: α-Amylase in smokers and nonsmokers group was found to be 206.25 and 169.85 U/mL respectively. Nonsignificant results were obtained while comparing the salivary α-amylase levels among the two study groups. Nonsignificant results were Assessment of Salivary
