Abstract

This study aims to identify the differences in the determinants that influence self-rated oral health (SROH) among Korean and American adults aged 20 years or older and the differences in objective oral health status between Korea and the United States. It included 13,068 Koreans and 5569 Americans who participated in the seventh Korea National Health and Nutrition Examination Survey and the 2017–2018 National Health and Nutrition Examination Survey. All analyses were conducted using the SPSS 25 program. The 39% of Koreans and 27.7% of Americans rated their oral health as “poor”. The mean SROH score was lower in Korea (2.66) than in the US (3.15). Conversely, objective oral health was better among Koreans. Further, an analysis of the differences in the predictors of SROH between the two countries confirmed that there were significant differences in age, household income, education level, insurance type (none), type of smoking, self-rated health, and decayed teeth index. Government-led projects or policy-based changes that can improve objective oral health status are needed to boost SROH in Korea, and subsequent studies should examine other objective oral health indices (e.g., periodontal disease) as well as differences in sociocultural backgrounds between countries.
