The prevalence of fluorosis-like lesions associated with topical and systemic fluoride usage in an area of optimal water fluoridation.


The frequency of using self-applied (over-the-counter) fluoride products and prescribed supplemental fluorides, and the prevalence of fluorosis-like enamel lesions in the permanent dentitions of children living in an optimally fluoridated urban community were investigated. Subjects were selected randomly, and consent forms and questionnaires concerning fluoride usage and residency status were provided to guardians prior to examination. After a supervised tooth brushing event, 300 consenting subjects were examined by the principal investigator using Dean's index to assess levels of fluorosis-like lesions. The principal investigator was standardized with another investigator prior to the examinations to obtain an interexaminer agreement level of 97%, and an intraexaminer agreement level of 96%. Portable dental equipment was used during all examinations. Chi-square analysis indicated no statistically significant difference between the frequency of tooth brushing with a fluoridated dentifrice at an early age and the prevalence of fluorosis-like enamel lesions. However, there was a significant difference (P less than 0.05) between the prevalence of fluorosis-like lesions, and the frequency of using prescribed fluoride supplements and gels, and over-the-counter rinses.
