PURPOSE: Increasing awareness about the importance of preventive dental care among low-income families has been considered to be key to overcoming nonfinancial access to care barriers for children. The purpose of this randomized, controlled trial was to measure the impact of postcard mailings on dental utilization by low-income children through a dental society program designed to increase access to dental care. METHODS:Five thousand eight hundred and seven low-income2- to 4-year-olds were randomly assigned to 1 of 3 groups: (1) Group 1 (n=2,014) received postcards containing information on how to enroll in the Yakima County Access to Baby and Child Dentistry program; (2) Group 2 (n=2,014) received the enrollment information as well as additional information on the availability of fluoride varnish and the need to visit the dentist by the age of 1-year-old; and (3) Group 3 (n=1,779) did not receive postcards. RESULTS:Preventive services utilization rates were not different among the groups: 61% for Group 1, 62% for Group 2, and 60% for Group 3, although rates were high for a Medicaid population. CONCLUSIONS:Postcard mailings did not significantly increase utilization of preventive dental services. Other strategies to increase utilization of preventive oral health measures are needed.
