The National Environmental Engineering Research Institute, Nagpur has developed a technique for renewing fluoride by chemical treatment, ka Nalgonda technique. It involves the addition of two chemical viz lime and alum in sequence followed by flocculation, sedimentation and f i Iteration. c Other measures Fluoride toothpastes are not recommended for children in areas of endemic fluorosis. Fluoride supplements should not be prescribed for children who drink fluorinated water.
