The Detroit Dental Health Project (DDHP)aims to promote oral health and reduce disparities within the community of low-income African-American children (0-5 years) and their main caregivers (14+ years), living in the City of Detroit. The driving theme of the Project is to identify determinants and design interventions to answer the following question: why do some low-income African-American children and their main caregivers have better oral health than others who live in the same community? The Project has 3 support cores, 4 research core projects and 1 pilot study. The Project has selected a multistage random sample of African-American families living in the poorest 39 Census Tracts in the City of Detroit. A total of 1,022 families were recruited and interviewed at a community center in Detroit during the year 2 (2002). We have collected data about the social characteristics of parents, families, and neighborhoods that are associated with disparities in oral health; lead levels in saliva and blood of the caregivers; and dietary intake. All these families will be recalled in the year 4 (2004) and year 6 (2006) for longitudinal data collection. We are currently developing a tailored multi-media educational intervention (Project #3), based on data collected in the first phase (2002). The educational intervention will be administered using a randomized controlled design in year 4 (2004). Additionally, the Project is evaluating the impact on access to dental care of a state-funded experiment on utilization where Medicaid children are managed like privately insured patients (Project #4).

Primary Outcome Measures:
  • Carious lesions [ Time Frame: Measures at baseline (2002-03); wave 2 (2004-05); wave 3 (2007) ]
    The carious process was measured using the International Caries Detection and Assessment System (ICDAS). The codes range from measurement of the first visible carious change in enamel (Code 1) to extensive cavitation (Code 6). Both primary carious lesions and lesions adjacent to restorations and sealants (CARS) were recorded,.

Enrollment: 2042

Arms Assigned Interventions
Experimental: Motivational Interviewing plus DVD
Caregivers watched a 15-minute educational video designed for the project emphasizing the importance of good oral health in children, and how the caregiver can keep children free from tooth decay. The MI interviewer engaged the parent in a discussion of their thoughts and concerns regarding their child's oral health and what changes they wished to make regarding monitoring their child's oral health. Feedback from the child's dental exam was also reviewed. MI+DVD caregivers received a brochure displaying a photo of their child and for those who chose to set specific goals for their child's oral health, those goals were listed on the brochure. Caregivers choosing not to set specific goals were offered a list of 10 project recommendations regarding dietary intake, oral hygiene, and dental check-ups. The session ended with a dialogue regarding possible barriers to implementing the personal plan and how the caregiver planned to overcome those barriers.
Behavioral: Motivational Interviewing
Active Comparator: DVD only
Caregivers watched the same educational video. At the end of the video, caregivers were given a glossy-printed brochure displaying the project developed recommendations as well as the child's photograph. The brochure was not re-mailed, as it was for the MI+DVD group and caregivers in this condition did not receive any feedback from the dental examination regarding their child's oral health status.
