Objective: The extent to which periodontitis is attributable to smoking in Korea has been examined rarely. The aims of this study are to investigate the association between smoking and periodontitis and to estimate the public health impact of smoking on periodontitis in Korea.
Methods: The Korean National Oral Health Survey 2006 collected nationally representative oral epidemiologic data for the Korean population. Examiners measured periodontal health status using the community periodontal index (CPI). Moderate-to-severe periodontitis was defined as a CPI of 3 or 4. Severe periodontitis was defined as a CPI of 4. Smoking status was defined as never-, former-, or current smoker. Age, gender, educational level, monthly income, and diabetes were examined as potential confounders.
Results: Among the total population, former smokers were 15.2% and current smokers were 19.7%. Adjusted Odds ratio for moderate-to-severe and severe periodontitis were as follows; current smokers 1.4 for moderate-severe periodontitis and 1.9 for severe periodontitis. The population attributable fraction of smoking for moderate-to-severe periodontitis was 7.6% and for severe periodontitis was 14.5%.
Conclusion: Smoking has a significant impact on periodontal health of the Korean adults.
