Urinary Fluoride As A Monitoring Tool For Assessing Successful Intervention In The Provision Of Safe Drinking Water Supply In Five Fluoride-Affected Villages In Dhar District, Madhya Pradesh, India by R. Srikanth, Anil Gautam, Suresh Chandra Jaiswal & Pavitra Singh

Endemic fluorosis was detected in 31 villages in the Dhar district of Madhya Pradesh, Central India. Out of the 109 drinking water sources that were analyzed, about 67 % were found to contain high concentration of fluoride above the permissible level of 1.0 mg/l. Dental fluorosis among the primary school children in the age between 8 and 15 served as primary indicator for fluoride intoxication among the children. Urinary fluoride levels among the adults were found to be correlated with drinking water fluoride in 10 villages affected by fluoride. Intervention in the form of alternate safe water supply in five villages showed significant reduction in the urinary fluoride concentration when compared to the control village. Urinary fluoride serves as an excellent marker for assessing the effectiveness of intervention program in the fluoride-affected villages.
