BACKGROUND: A positive association has been reported between alcohol and periodontal disease. Therefore, this study is conducted to assess the relationship between alcohol intake and severity of periodontal disease in a large probability sample of the Korean population using the Korea National Health and Nutrition Examination Survey (KNHANES). METHODS: Data from KNHANES, conducted between 2008 and 2010 by the Division of Chronic Disease Surveillance under the Korea Centers for Disease Control and Prevention and the Korean Ministry of Health and Welfare, were used for this study. The presence of periodontal treatment needs according to demographic variables and anthropometric and hematologic characteristics of the participants are presented as means with their standard errors. Multivariate logistic regression analyses were used to assess the associations of periodontal treatment needs with the amount of alcohol intake and other variables including smoking and the number of times of toothbrushing per day. RESULTS: An association between drinking alcohol and periodontal treatment needs could be seen in men after adjustment for variables. Adjusted odds ratios (ORs) and their 95% confidence intervals (CIs) in males were 1.271 (1.030 to 1.568) for heavy drinkers after controlling for age, smoking, body mass index, exercise, education, income, white blood cell count, diabetes, hypertension, metabolic syndrome, and number of toothbrushing episodes per day (model 3). Adjusted ORs and their 95% CIs in males were 1.569 (1.284 to 1.916) for alcohol use disorders identification test (AUDIT) level ≥20 in model 3. ORs increased with the increase in alcohol consumption levels and AUDIT levels. Statistically significant correlations between drinking and periodontal treatment needs could not be seen in female heavy drinkers or female drinkers with AUDIT levels ≥20. CONCLUSIONS: Men with higher alcohol intake were more likely to have a higher prevalence of treatment needs regardless of their age, socioeconomic factors, systemic conditions (including diabetes, hypertension, and metabolic syndrome), and number of times of toothbrushing per day in multivariable adjusted models. By contrast, in women, alcohol intake was not independently associated with periodontal treatment needs. Alcohol consumption was discovered to be a potential risk indicator for periodontal treatment needs in men in this study.
