Demographic and socioeconomic predictors of dental care utilization.

The authors analyzed a comprehensive, nationally representative data set from the 1989 National Health Interview Survey to determine what factors are related to dental care utilization. The authors estimated the percentage of low-income and minority adults who reported visiting a dentist in the past year by race, income, employment status, dental insurance coverage status, sex, health status, education, marital status, age and major activity. Data analyses focused on 49,687 18- to 64-year-old dentate respondents, who were black, Hispanic or white. The authors found large differences in dental care utilization between blacks, Hispanics and whites, when controlling for education, income, age and other variables.
