Introduction: Cigarette smoking has been recognized to be a risk factor for progression of periodontal disease . Due to less inflammation and bleeding in the presence of clinical signs of periodontal disease in smokers than in nonsmokers and given the conflicting results of studies on changes in the epithelium and gingival connective tissue by smoking, this study was performed to evaluate the t...

Background and Objective: Smoking can be associated with the decreasing gingival blood flow and epithelial changes. The aim of this study was to evaluate the histopathological changes of gingival epithelium and connective tissue in smokers. Methods: The study was case-control. Sixty male patients (28 smokers and 32 nonsmokers) suffering chronic periodontitis were participated...

OBJECTIVE To compare the serum thiocyanate levels in smokers, passive smokers and never smokers. METHODS Serum thiocyanate was analyzed on 135 self reported smokers, never smokers and passive smokers by UV-Spectrophotometry (Manual method of Bowler). RESULTS The mean serum thiocyanate concentration (112 +/- 36.6 micromol/L) of smokers was significantly higher (p value < 0.001) as compared t...
