TESTLET G
A local dental hygienists' association and a local faith-based organization collaborate to target a school in a nonfluoridated area for a comprehensive oral disease prevention program. The school serves a population that consists of 50% Medicaid-eligible children, and 75% of them are on the school lunch program. The ethnic group representation is 15% Hispanic American, 5% African American, and 80% non-Hispanic white. The community water supply naturally contains 0.3 ppm F. Children in grades 2 and 6 are screened annually by a public health dentist who uses a mirror, an explorer, and dental light. Preschool and grade K children are screened twice a year with a tongue blade and light. Data for 2011 indicate a 20% urgent decay rate across all ages. A sealant program is conducted in grades 2 and 6, and a fluoride varnish program is conducted with the preschoolers and grade K, including two applications annually. A pizza party is planned for each classroom that has a 100% return rate of parental consent forms for the sealant and fluoride varnish programs. Educational presentations are made in classrooms and with parent groups twice a year. Three portable dental units are borrowed from the regional office of the state health department to conduct the program. The program is funded with a grant and staffed with volunteer hygienists and students from a local dental hygiene program.
