Rapid economic development and population growth globally, in particular in cities, are hugely expanding expectat...

A comparative study of the conditions that place and those in the adjoining are^ would show that the sectional incidence mottled enamel can be correlated with ^ occurrence of fluorides in the drinking wa , supplies. Thus, the analysis of the drinkjj1^ water supply of the afflicted persons shows ^ presence of 0.4 to 0.5 parts (per 100,000) fluorine, whereas the water supplies for the otn section...
