title: Determinants of requests for water fluoride assay among North Carolina dentists.
abstract: Fluoride content of drinking water is an important criterion in prescribing fluoride supplements. The majority of practicing dentists and physicians prescribe fluoride supplements, yet many apparently are unaware of the fluoride levels in their patients' drinking water. Characteristics of North Carolina (NC) dentists, their practices, and their communities were investigated to determine factors associated with whether they requested fluoride assays of their patients' drinking water. Comparisons were made between dentists sampling (assaying) and those not sampling. Licensure renewal files provided characteristics of the 79 pedodontists and 1768 general practitioners (GP's) active in NC. Eighty-eight GP's (5%) and 26 pedodontists (33%) requested water fluoride analyses between December, 1982, and May, 1983. Significant predictors of fluoride assay request by GP's were the dentist's age, the geographic region of the state, the number of dentists in the practice, and an interaction between geographic region and the number of dentists in the practice. Younger GP's and those with fewer dentists in the practice were more likely to request fluoride assays of patients' water. For pedodontists, dentist's age and geographic region were significant predictors. Additional training concerning the need for water fluoride assay appears necessary, especially among older practitioners.
