Abstract

This study aimed to evaluate the effectiveness of the health insurance coverage of dental scaling (introduced in 2013) using the Community Periodontal Index of Treatment Needs parameter among Korean adults aged 20 years or older. We used the Korea National Health and Nutrition Examination Survey data from before and after 2013 to analyze the statistical significance and associations of the covariates with the prevalence of healthy periodontal tissues, prevalence of people in need of scaling, and prevalence of periodontal diseases. The results showed that the prevalence of healthy periodontal tissues increased by 4.9% (from 34.2% to 39.1%), the number of people in need of scaling decreased by 5% (from 65.9% to 60.9%), and the prevalence of periodontal diseases increased by 7.2% (from 23.4% to 30.6%). Moreover, after the scaling coverage policy, the odds ratio of the prevalence of healthy periodontal tissues was 1.10 times higher, the prevalence of the need for scaling was 1.5 times higher, and the prevalence of periodontal diseases was 0.90 times lower. Therefore, the state should formulate policies that provide dental biofilm management through a disclosing agent, impart education about oral hygiene, and develop a health management system that enables the concurrent management of periodontal diseases and systemic diseases.
