Objectives: The purpose of this study was to evaluate the risk indicators of periodontal disease in a representative sample of Korean adults aged between 18 and 44 years.
Methods: Data of 6,485 adults were derived from the Fourth Korean National Health and Nutrition Examination Survey, which was conducted from 2007 to 2009. Demographic, socioeconomic, and oral health-related behavioral data were collected as independent variables. The Community Periodontal Index (CPI) was used as a dependent variable. The chi-square test and logistic regression analysis were performed to identify the relationship between the CPI and the other variables.
Results: Multiple logistic regression analysis revealed that periodontal pocket formation (4 mm or more) was related with sex, age, and income level, irrespective of whether the mother engaged in economic activities in childhood, smoking experience, dental flossing, and use of interdental brushes. The subjects in the lowest-income quartile and those who were current smokers had a higher risk of pocket formation (odds ratios, 1.43 and 1.74, respectively) than those in the highest-income quartile and those who had no smoking experience, respectively.
Conclusions: This study confirmed various risk indicators of periodontal disease in Korean adults, using Korean national survey data. Smoking cessation, dental flossing, and efforts to decrease socioeconomic inequality should be encouraged to decrease the risk of periodontal disease.
