The purpose of this study was to examine the effects of an oral health educational intervention on knowledge and behavior-specific cognitions and affect in caregivers of children from 2 to 5 years of age. This was a descriptive study, with a convenience sample of 425 Head Start caregivers who attended one of 18 oral health educational programs throughout Miami-Dade County. Four research questions addressed the relationship between the oral health educational intervention and prior related behavior, personal factors, behavior-specific cognitions and affect, knowledge, and intent. The educational program was found to have a significant effect on caregivers' knowledge, cognition, affect, and intent to provide oral healthcare to their children. Educational programs have a positive impact on caregivers to increase oral health knowledge and intent to perform preventive oral health-promoting behaviors in this underserved population. Effective educational interventions are necessary in order to increase overall health in children and to decrease oral disease.
