Abstract

Although there were two oral health status surveys of the disabled in Korea, not enough subjects were surveyed for each type of disability in their 40s or older. The purpose of this study is to identify oral health status by disability type in 40s or older using NHIS-HEALS (National Health Insurance Service-National Health Screening Cohort) data. The definition of periodontitis was defined as a patient in cases where periodontal surgery was required in the Health Examination (HEALS) DB, or where subjects who received subgingival curettage, tooth extraction due to periodontitis, or severe periodontal treatment, such as periodontal flap operation with subgingival curettage, bone graft for alveolar bone defects, or guided tissue regeneration, were classified into the severe CP group. The number of toothbrushes per day was investigated by HEALS. The qualification DB excluded deaths from 2002 to 2005, and investigated age, gender, income quintile, disability severity classification and disability type classification. Dental area disability rating was defined based on disability severity and disability type classification. As a result of this study, the following conclusions were obtained. The prevalence rate of chronic periodontitis was 42.5% for non-disabled persons, 48.8% for mild disabled cases in dental areas, and 47.6% for severely disabled. Men with disabilities, like non-disabled people, had a higher prevalence rate than women. Non-disabled people had a higher percentage of those who had less than a toothbrush twice a day than those with disabilities. For a more accurate investigation in the future, a sampling study is required considering the disability type, age, gender, and region of the disabled.
