Three questionnaire surveys were conducted with teachers and principals in the National Preventive Dentistry Demonstration Program. The questionnaires were mailed toward the end of the first, second, and fourth years of the program. About 75 percent of the teachers and 90 percent of the principals returned questionnaires each year. Analyses of their responses indicated they understood the program's protocols for providing dental health lessons, brushing, and fluoride mouthrinse and tablets. Grade level was inversely related to the time teachers said it took to deliver these procedures and their willingness to continue using them. However, most respondents had positive attitudes about the program. Their chief complaints centered on the time required to provide the program and the inconveniences caused by having it in the school.
