Critical Evaluation of the Composition and Use of Topical Fluorides.

This report reviews the current status of various topical fluoride systems commonly used for caries prevention; these systems include professional fluoride applications, prophylaxis pastes, varnishes, rinses, gels, and dentifrices. Although the cariostatic benefits of professional applications are well-established from early studies, the magnitude of benefit relative to other preventive measures needs to be re-assessed under current conditions. Significant cariostatic benefits from fluoride prophylaxis pastes remain to be established, as does the relative efficacy of fluoride varnishes in comparison with other fluoride measures. The established cariostatic activity of fluoride rinses with supervised usage needs confirmation under normal home usage conditions. There is inadequate evidence to justify either increasing or decreasing the concentration of fluoride in conventional dentifrices whose efficacy is well-established. Based on limited clinical data and supportive laboratory data, fluoride appears to be effective for preventing root-surface caries. [ABSTRACT FROM PUBLISHER]
