Association of Self-Perceived Oral Health and Function with Clinically Determined Oral Health Status among Adults Aged 35–54 Years: A Cross-Sectional Study

Abstract

This study aimed to analyse the association of self-perceived oral health status (OHS) and functions with clinical OHS in Korean adults aged 35–54 years. The study was designed as a cross-sectional study using data from the Fourth Korea National Health and Nutrition Examination Survey (2007–2009). A total of 6605 subjects aged 35–54 years who completed the oral examination and questionnaires were included. An association of self-perceived OHS and functions with clinically determined OHS was confirmed by a complex-samples general linear model. Data on socioeconomic variables, i.e., household income and education level, self-perceived OHS and functions, such as chewing and speaking, were collected by trained interviewers. The clinical OHS was determined by trained dentists and included the number of untreated decayed teeth (DT); decayed, missing, and filled teeth (DMFT); prosthetic and periodontal status. The combined score was estimated as the sum of self-perceived OHS and functions. Based on the estimation coefficient, the clinical variables that were most strongly associated with self-perceived OHS and functions were, in order, periodontal status, prosthetic status, DT, and DMFT. In addition, the combined score for self-perceived OHS and functions was associated with household income, education, and clinically determined OHS.

Did the Expansion of Insurance Coverage for Oral Health Reduce Self-reported Oral Health Inequalities in Korea? Results of Repeated Cross-Sectional Analysis, 2007–2015

“…4 In previous studies, SROH has shown a high reliability with clinical oral health outcomes. 32 Thus, SROH is regarded as a practical and easily interpreted measure to assess inequalities in the oral health of a population. 11,12,33,34 We confirmed the same patterns of the outcome variable through a sensitivity analysis and robustness check.…”

Subjective oral health status in an adult Korean population with asthma or allergic rhinitis

“…[ 9 ] In a study from the KNHANES IV, self-perceived oral health status and function were strongly associated with clinical oral health status, which included the number of untreated decayed teeth (B = 0.405, P < .001); number of decayed, missing, and filled teeth (B = 0.126, P < .001); prosthesis scores (B = 0.691, P < .001); and periodontal scores (B = 0.700, P < .001), as determined by trained dentists. [ 10 ] Using self-rated oral health in population surveys is a more valid, reliable, and cost-effective measure than carrying out examinations, as it can quickly identify the state of the populations oral health and associated factors.

<p>Self-Reported General and Oral Health in Adults in the United States: NHANES 1999-2014</p>

“…In the last 2 decades, studies have reported on the relationship between oral and general health as well as identified factors associated with reported health status. [1][2][3][4][5] An analysis of available new data on the topic provides an opportunity to expand the literature by providing more current evidence on this relationship, given its importance for policy and program development, and dental public health practice. In addition, measures of general and oral health have the potential to demonstrate a linear change when oral and general health are measured directly with other closely related variables.…”
