Abstract

OBJECTIVES
The aim of the study was to analyze the factors related to the illegal dental treatment experience (IDTX) among Korean adults.
METHODS
The raw data for the analysis of IDTX among Korean adults were obtained from the dataset of the Fourth Korea National Health and Nutrition Examination Survey conducted in 2007-2009. Stratified weighted subjects aged > or =45 years were selected according to region by using clustered sampling methods. In total, the data of 9,254 subjects, who participated in the interview and dental examinations related to the experience of illegal dental treatments, were analyzed using chi-square test, general linear model, and logistic regression analysis with complex sampling design by considering demographic and socioeconomic variables (age, gender, region, educational level, household income, and medical and dental delivery system) as well as oral status variables (prosthesis and number of natural remaining teeth).
RESULTS
IDTX rate was <10% among adults aged 35-44 years or below. However, it increased to 15% among adults aged 45-54 years and was >30% among adults aged > or =65 years. The age group with a high IDTX rate coincided with the age group with a high number of lost teeth. Most of the IDTX cases were presumed to be prosthetic treatments. The model comprising demographic, socioeconomic, and oral status variables had the highest explanation power. Significant variables were educational level, household income, prosthesis status, and number of remaining teeth. Women and persons under the medicaid system were more likely to undergo illegal dental treatments.
CONCLUSIONS
Comprehensive prosthetic treatments are suggested to be included in the care services of the national health insurance and medicaid system to reduce the number of illegal dental treatments.
