Feds: Lower Amount of Fluoride in WaterNEW YORK - The government is lowering the recommended amount offluoride in drinking water...Stobbe, Mike
Overall all water quality was found unsatisfactory for drinking purpose without any treatment. So an urgent need is to educate the people on the causes of flurosis, encouraging defluoridation technique for providing fluoride free water in the study ar...
Results: Prevalence of fluorosis in Maroon, Karoon and Karkheh branches was 62.2%, 34.9% and 57.3% respectively; and the average of DMFT was 1.33, 1.20 and 0.6. Increase in fluoride level caused increase in fluorosis prevalence (P Less than 0.001). Fluoride increment in drinking water and ...
