A map of natural fluoride in drinking water in Sudan

Fluoride is present in most natural elements, in particular in water, with the level being different depending on the region. The level theoretically ideal at 1 mmg/l, is in regions of the Sudan, either surpassed or not attained. After looking at the geography of the country, the levels of fluoride in water was established for each region. It would be ideal, in the case where fluoride was absent, to use an artificial fluoridation scheme.
