The effect of smoking on gingival crevicular fluid levels of myeloperoxidase.

Objectives : To compare the gingival crevicular fluid (GCF) myeloperoxidase (GM) levels in smokers and non-smokers. Materials and methods : This study comprised 45 subjects: (a) 12 smokers with periodontitis, (b) 10 non-smokers with periodontitis, (c) 11 smokers with healthy periodontium, and (d) 12 non-smokers with healthy periodontium were recruited for the study and their GM levels were analyzed. Results and conclusion : GM levels were significantly higher in smokers with periodontitis compared with others. Hence, more incidence of mutagenesis and cytotoxicity were noted at sites of inflammation mediated by GM in smokers compared with non-smokers.

Periodontal Disease and Coronary Heart Disease.

The epidemiological cohort randomized studies have demonstrated an association between periodontal disease and coronary heart disease. The study was conducted on 241 subjects with verified CHD from a Department of Cardiology and 50 subject without CHD from Govt. Dental College PGIMS, Rohtak. Information on diabetic states, smoking habits, alcohol consumption and lipid profile was obtained. Full month probing depth, clinical loss of attachment and bleeding on probing was performed.The CHD group had a significantly higher probing depth, clinical loss of attachment and bleeding on probing while lipid profile become opposite as compared to non-CHD group. Clinical loss of attachment increase with risk factors such as smoking, alcoholism, male,increasing age, triglycerides and HDL-C levels. The present study showed a positive association between periodontal disease&CHD in agreement with previous studies.
