Change over a period of 9 years in self-reported oral health of a middle-aged population using 4-6th KNHANES data / 대한구강보건학회지

OBJECTIVES: To explore changes in self-reported oral health in middle-aged Koreans over a period of 9 years. METHODS: This study design was a cross-sectional analysis. This study analyzed the data of 18,845 middle-aged (45-64 years) subjects who participated in 4-6th Korea National Health and Nutrition Examination Surveys (KNHANES). A complex-sample chi-square test was used to analyze self-reported poor oral health according to sex, household income, and education. A complex-sample logistic regression analysis was used to identify the changes in the factors. SPSS 23.0 and the R ver. 3.5.1 statistical package were used for the analyses. RESULTS: Poor oral health have been decreased by 5.3% over the 9-year period. Middle-aged men were more likely to report their oral health as worse than women. The lower income and education groups reported their oral health as poor compared to the higher income and education groups. The factors affecting self-reported poor oral health over the 9-year period were sex, income, and education. CONCLUSIONS: More than half of the aged population reported their oral health as poor. Oral health policies should be established for the aged population, including the middle-aged population, for long-term plans.

A association between self-reported oral health and oral health status among Korean male soldiers aged 18-24 / 대한구강보건학회지

OBJECTIVES: This study is aimed to evaluate the correlation between self-reported oral health and caries experience, and to find out factors that affect perceived oral health status and treatment need in Korean male soldiers aged 18 to 24. METHODS: The cross-sectional oral health examination and questionnaire survey about the attitude of oral health were conducted (n=2,436). The survey contained self-reported oral health status, self-reported dental treatment need and associated factors. RESULTS: Caries experience like DMFT, DT, FT, and MT indices were significantly different by selfreported oral health status, as well as the self-perceived dental treatment need (P<0.005). Experience rates of 'tooth pain', 'periodontal pain', 'tooth hypersensitiveness', 'gingival bleeding', 'tooth cavity', 'oral malodor', 'need prophylaxis', 'former dental treatment', 'smoking' and 'scaling' were different by selfreported oral health status and self-perceived dental treatment need (P<0.05). CONCLUSIONS: Subjective oral health perception reflected objective oral health status and other oral health related factors.
