Smoking, with its destructive effects, can induce oxidative stress in the body cells. The present study aimed to evaluate the level of salivary vitamins C and E in smokers and nonsmokers. </span></span></span></span><br> <span style="unicode-bidi:embed"><span style="line-height:115%"><b><span style="line-height:115%"><span style="color:black">Methods and Materials:</span></span></b><span style="line-height:115%"><span style="color:black"> In this experimental research, 28 heavy-smoker men (more than one cigarette pack per day), 28 light male smokers (less than one cigarette pack per day), and 28 nonsmoker men aged 25-40 years old were included. Unstimulated saliva was collected using the spitting method. The salivary Vitamin C and E amounts were measured using the Colorimetry method. Data were analyzed by SPSS21 statistical software. ANOVA, Tukey tests, and descriptive statistics analyzed the data. </span></span></span></span><br> <span style="unicode-bidi:embed"><span style="line-height:115%"><b><span style="line-height:115%"><span style="color:black">Results:</span></span></b><span style="line-height:115%"><span style="color:black"> The mean salivary vitamin C in nonsmoker, light smoker, and heavy smoker men was 2.17 &plusmn; 0.39, 2.14 &plusmn; 0.37, and 1.97 &plusmn; 0.252 mg/dl, respectively. There were no significant differences among the three groups in salivary Vitamin C (<i>p</i> > 0.05). The mean salivary vitamin E in nonsmoker, light smoker, and heavy smoker men was 1.2 &plusmn; 0.48, 0.659 &plusmn; 0.363, and 0.42 &plusmn; 0.25 mg/dl, respectively. There were significant differences among the three groups in salivary vitamin E (<i>p</i> = 0.05). Salivary vitamin E of light and heavy smoker men was lower than nonsmokers. </span></span></span></span><br> <b><span style="line-height:115%"><span style="color:black">Conclusion and Discussion: </span></span></b><span style="line-height:115%"><span style="color:black">The results of this study demonstrate that, despite the reduction in Vitamin C, smoking does not significantly affect salivary vitamin C levels in non-stimulated saliva. However, smoking does reduce the amount of vitamin E in non-stimulated saliva.</span></span><br> <br> <img alt="" src="./files/site1/images/888.jpg" style="width: 1000px; height: 36px;" ></span></span></div> Cigarette smoking, Saliva, Vitamin E 232 232 http://ibj.pasteur.ac.ir/browse.php?a_code=A-10-4696-239&slc_lang=other&sid=1 Majid Jafari No Mahdiyeh Zarabadipour Yes Sajad Irandoost No
