Abstract

Background and objective: Gingival bleeding reduction in smokers has been associated with decreased blood vessel density. The mechanism of suppressive effect of cigarette Smoking on blood vessel density is not precisely defined. The aim of this study was to evaluate the impact of Smoking on Angiogenesis by assessing Mast cells density and VEGF expression in Chronic periodontitis. Materials& Methods: 52 paraffin embedded block of gingiva tissues with periodontitis obtained from 30 nonsmokers and 22 smokers undergoing flap surgery were examined immunohistochemically for VEGF expression. Mast cell counts was completed on toluidine blue stained slides. Exposure to cigarette Smoking was calculated by the number of packs × year. Patients were classified into 4 groups based on the number of smoked cigarettes. The correlation between VEGF expression and Mast cell counts was evaluated and compared in nonsmokers and smokers. Results: The mean number of Mast cells (p=0. 004) and average value of VEGF expression (p = 0. 000) in nonsmokers was significantly higher than smokers. No correlation was noted between VEGF expression / Mast cell counts and number of smoked cigarettes in four groups of smokers (p=0. 29, 0. 12, 0. 20 and 0. 11, respectively). Conclusion: Mast cells and VEGF expression may account for suppressive effect of cigarette Smoking on blood vessels in periodontitis.
