As a way of containing the soaring medical expenditure, a global budgeting scheme for dental services under the National Health Insurance (NHI) was launched in 1998. However, according to the statistics from the Department of Health, the use of dental services in Taiwan has steadily increased since then. Usually, an increase of dental use is an indicator for advanced stages in public health development, especially an increase of dental use among children. This study explores the factors associated with dental use among children 6 to 12 years old. Andersen’s Behavioral Model was used as a guideline for selecting variables to predict the likelihood of visiting a dentist during the past year. The study data were taken from the 2005 National Health Interview Survey. A total of 2187 children aged 6 to 12 were identified from the survey and logistic regression models were used to evaluate the importance of variables in predicting dental use. The results show that older children, number of teeth-brushing, preventive dental check, parents education levels, household income, density of dentists, and health status were significant predictors for dental use in the past year. Andersen’s behavioral model was developed to identify potential barriers of access to medical services. Our results showed that enabling factors, such as household income and density of dentists, had greater impact on the use of dental services, indicating that more policy efforts should be made to create a more equitable delivery system for dental services in Taiwan.
