This study assessed the ability of a conceptual model of health-related behavior to predict preventive dental-related behaviors (brushing, flossing, and dental visits) and to explain race/ethnic differences in these behaviors in a probability sample of 787 adults aged 18-93 years living in the Detroit tri-county area. The Health Belief Model integrated with theory-related conceptual variables were used as the basis for the study. Multiple regression analyses determined variables predictive of behaviors. Race (p<.05), expectations of retaining natural teeth (p< .01), self-efficacy (p<.05), and education (p<.05) were significant predictors of brushing frequency (R2=0.11). Persons with higher expectations of retaining natural teeth, more education, higher self-efficacy and white race tended to brush more frequently. Education (p<.05) and self-efficacy (p<.001) were significant predictors of flossing frequency (R2=.35). Persons with more education and higher self-efficacy tended to floss more frequently. Frequency of flossing did not differ between race/ethnic groups in multivariate analyses. Race (p<.05), education (p<.01), expectations of retaining natural teeth (p<.001), self-efficacy (p<.01), and perceived barriers (p<.001) were significant predictors of dental visit frequency (R2=.29). Persons with higher expectations of retaining natural teeth, more education, higher self-efficacy, fewer barriers and white race had more dental visits. Income and private insurance were not significant predictors of these dental behaviors when behavioral variables were included in the model. Dental health promotion programs focused towards enhancing mutable factors, such as self-efficacy and expectations of retaining natural teeth, may benefit at-risk race/ethnic and economic subgroups.
