Abstract
This study aims to determine the association between UpH (<5.5), Community Periodontal Index (CPI), and the number of remaining teeth—cumulative indicators of oral health—using data from the 7th Korea National Health and Nutrition Examination Survey (KNHANES, 2016–2018), which represents the Korean population. Data from 12,689 adults aged 19 years and older who had periodontal examinations were analyzed. Logistic regression analysis was performed after adjusting for demographic, health, and health-related behavioral factors as covariates to determine the association between UpH, CPI, and the number of remaining teeth. This study found that UpH (<5.5) was associated with CPI and the number of remaining teeth. For UpH (<5.5), the odds ratio for CPI (≥4 mm) was 1.19 times (95% CI: 1.06–1.33). The risk of tooth loss was 1.25 times (95% CI: 1.06–1.48) for those with 0–19 remaining teeth and 1.20 times (95% CI: 1.07–1.34) for those with 20–27 teeth. The results revealed an association between UpH, CPI, and the number of remaining teeth. However, further longitudinal research on UpH and oral status is necessary.
