The dental utilization patterns of Chicanos and Anglos were compared using several socio-demographic variables to explain any differences or similarities existing between the two groups. Data for this study were part of an extensive household survey conducted in Pima County, Arizona, to obtain information on various health indicators concerning utilization, delivery systems, access, satisfaction of health consumers, and demographic characteristics of consumers. During December 1972 and from January to March 1973, personal interviews were conducted in 1,681 households. Of these, 1,581 were used for this study. Variables used were: family income, family size, age, sex, education, residence, socioeconomic status, and cultural variation. Sex and residence were dummied in the regression analysis. Findings included: Chicanos not only underutilized dental services, but the services they did use were primarily those of a "symptomatic" nature; for Chicanos, socioeconomic variables played a negligible role in explaining dental utilization, although they were more important for Anglos; a substantially larger proportion of Chicanos had not seen the dentist in the past year, and of those who had, the pattern of frequency of visitations was a lesser number of visits for Chicanos than Anglos; and Chicanos had a higher proportion of tooth extractions and dentures.
