Aim: The present study was carried out to compare the periodontal status & pattern of attachment loss in periodontitis patients; who are current smokers, current tobacco chewers & non-smoker and non-tobacco chewers. Material and Method: 150 male subjects ranging from 18 to 60 years having periodontitis were selected. Smoking and tobacco consumption history was obtained through personal interview. Then patients were divided into 3 group current smokers, current tobacco chewers and non-smoker & non-tobacco chewer. Clinical parameters include loss of attachment, marginal gingival index, probing pocket depth. Female patients, patients of tobacco chewers and smokers (both), past smokers &/or tobacco chewers, patients who had undergone periodontal treatment in last 3 months, patients who have other forms of periodontitis & patients who have systemic history are excluded. Collected data will be analyzed statistically. Results: The current smokers and tobacco chewers exhibited higher level of attachment loss and probing pocket depth than nontobacco chewer and nonsmokers. The results of analysis showed that the attachment loss in smokers and chewers 1.3 mm and 0.7 mm more than nonsmokers and nontobacco chewers. Bleeding on probing was more in nonsmoker and nontobacco chewers than smokers and tobacco chewers. Conclusion: The overall pattern of attachment loss in smokers exhibited more than tobacco chewers, nonsmokers and non-tobacco chewers. Both tobacco smoke and tobacco components may reduce gingival blood flow and gingival bleeding. This could be either due to vasoconstriction of gingival vessels or to the heavier keratinization of the gingiva in smokers.
