Abstract:
There are many risks factors leading to periodontitis. Smoking, especially cigarette smoking has been questioned to be one of them. It is interesting to investigate whether smoking habit among Thai population attributed to the occurrence of periodontitis. A cross -sectional study was carried out at a health centre in Bangkok. 190 males and females aged 35-55 years old, both males and females, were assessed their periodontitis status (ie pocket depth and attachment loss) using Community Periodontal Index (CPI), and using Plaque Index (PlI) and Simplified Calculus Index (CI-S) for plaque and calculus deposits Their smoking habits were also interviewed simultaneously. The results showed that the likelihood of having periodontitis among smokers was 1.8 times more than non-smokers (CI = 1.01-3.47, p <0.05), Among smokers those having smoked for more than 10 years were 4 times more likely to have periodontitis than those having smoked less than 10 years (CI = 1.57-10.22, p < 0.01). Regarding to the number of cigarette smoke per day, those subjects smoke > 10 cigarettes per day was 3 82 times more likely to have periodontitis than those smoke S 10 cigarette per day (CI = 1.53-9.56, p <0.01) Significant difference of plaques and calculus deposits between smokers and non- smokers were not found in this study. Thus it is concluded that cigarette smoking is likely to play a significant role in higher prevalence of periodontitis in Thai adults population as studies in other populations have shown
