ABSTRACT Children from low-income families face barriers to preventive dental care (PDC) and are disproportionately affected by dental caries. The Access to the Baby and Childhood Dentistry (ABCD) program of Washington State is targeted to Medicaid-insured children <6 years of age to improve their access to PDC.
To test the hypothesis that residing in an ABCD county improves the likelihood of receiving PDC and, to compare PDC use among young, Medicaid-insured children in Washington to national statistics.
We extracted 2003 Washington Medicaid dental claims for continuously enrolled children <or=6 years of age. Multivariable analysis was performed to identify variables independently associated with >or=1 preventive dental visit (PDV) in 2003. For national comparison, we used the 2003 Medical Expenditure Panel Survey (MEPS).
Among Medicaid-insured children <or=6 yrs of age from WA counties with ABCD program, 45% had at least 1 PDV compared with 36% from non-ABCD counties (P < .001) and 37% of US children with continuous private insurance (P < .001). There were significantly higher adjusted odds of a PDV for children from ABCD counties relative to non-ABCD counties (odds ratio: 1.30 [95% confidence interval: 1.05-1.60]).
We confirmed our hypothesis that residing in an ABCD county was associated with a higher likelihood of having >or=1 PDV in 2003. We also found that significantly more children in established ABCD counties received PDC compared with privately insured US children. These findings provide additional evidence that the ABCD program reduces disparities in dental care access among young, Medicaid-insured children in Washington and point to the importance of expanding the ABCD program to other states.

    ABSTRACT: The authors surveyed parent-leaders about aspects of a dental home for children with special health care needs (CSHCN). State leaders in two advocacy groups completed the survey; the response rate was 70.6% of all states. Two of the most highly rated aspects of a dental home, endorsed as "essential" by 89% of respondents, pertained to dentist-parent interactions: the dentist listens carefully to the family, and the dentist helps the family feel like a partner in treatment decisions. Likewise, 89% said it was essential that insurance coverage allows the child to see needed providers. Dentists' lack of knowledge or willingness to treat CSHCN and refusal of Medicaid insurance coverage were identified as major barriers to care. More than 84% of respondents reported that parents were unaware of the recommendation to establish dental care by 1 year of age. Establishing policy and educational strategies should help parents meet this dental health goal.

    ABSTRACT: The purpose of this study was to estimate age at first dental visit (FDV) and identify variables predicting earlier visits for Medicaid-enrolled children at Iowa Federally Qualified Health Centers (FQHC). Statewide Medicaid claims data were used to draw a random sample of children who received their FDV prior to six years old at a FQHC, were Medicaid-enrolled within the first two months of life, and remained continuously enrolled over the study period. Forty children from each of five FQHCs had their dental charts abstracted and merged with other Medicaid records and birth certificate data. The logarithmic age at FDV was regressed against several predictor variables. Mean and median ages for FDV were 25.6 and 23 months old, respectively. When controlling for other variables, there were differences in FDV age according to: mother's marital status (P=.04); whether the child had any medical well-child visits (MCVs) at a FQHC prior to the FDV (P<.001); and which FQHC the child visited. Only approximately 28 percent of these children, however, had any MCV at the FQHC. Medicaid-enrolled children who visited Federally Qualified Health Centers for their first dental visit were seen at an earlier age than previously recorded for such health centers (mean=four years old). Children who also received any medical well-child visits at FQHCs were more likely to have earlier FDVs.

    ABSTRACT: Pediatric dental caries is the most common chronic disease among children. Above 40% of the U.S. children aged 2-11 years have dental caries; more than 50% of them come from low-income families. Under dental services of the Medicaid program, children enrolled in Medicaid must receive preventive dental services. However, only 1/5 of them utilize preventive dental services. The purpose of this overview is to measure the impact of Medicaid dental benefits on reducing oral health disparities among Medicaid-eligible children. This paper explains the importance of preventive dental care, children at high risk of dental caries, Medicaid dental benefits, utilization of dental preventive services by Medicaid-eligible children, dental utilization influencing factors, and outcome evaluation of Medicaid in preventing dental caries among children. In conclusion, despite the recent increase of children enrolled in Medicaid, utilizing preventive dental care is still a real challenge that faces Medicaid.
