Fluoride concentration relative to the acceptable range (electrometric ion-selective electrode measurement; acceptable range mostly 0.6-0.8 ppmF) vs None (descriptive proportion meta-analysis)
Water samples with fluoride concentration above the acceptable range · Artificially fluoridated public water supply in Brazilian cities (water samples under external control)
In the Southeast Brazilian region, a pooled 11.5% of water samples had fluoride above the acceptable range; ungraded.
