External control of fluoridation in the public water supplies of Brazilian cities as a strategy against caries: a systematic review and meta-analysis.

ABSTRACT:

Background

Among the methods currently available to provide fluoride in population levels, fluoridated water is the most successful for presenting high efficacy, safety and good cost-benefit. However, recent studies on external control have shown great variability of fluoride concentrations in the water from treatment stations in Brazilian cities, which must present concentration between 0.6 and 0.8 mg/L to be considered acceptable in most cities. Thus, this study aimed to perform a systematic review of the literature to assess the adequacy of fluoride concentration in the water in Brazilian cities using external control.

Methods

The protocol was registered in PROSPERO. Six databases were used as primary search sources and three databases were used to partially capture the "
