There have been reports of endemic fluorosis in Haryana but most of the areas reported have not been studied or screened. In a study conducted to assess fluoride levels in Gurgaon (now Gurugram) the fluoride concentration in water samples in Pataudi varied from 0.95 to 2.42 mg/L. In Mahendergarh district, in Narnaul block, 126 children were examined and 42 were found suffering from dental fluorosis which is (33.33%). In Sihma, 90 children were examined and 43 were found suffering from dental fluorosis which is (47.7%). This study was done as per the WHO oral survey method and was carried out during March–April 2019 in Gohana Block of Haryana. This study showed in a sample of 50 children about 5% of children surveyed in the age group of (3 to 15 years) showed evidence of Dental Fluorosis. Out of a sample of 50 children, 40 of these children had no or questionable fluorosis, 4 had mild fluorosis, one had moderate fluorosis and none had severe fluorosis. Since this is a preliminary study, further studies are warranted in this area, where water samples should be taken and analysed for fluoride content. This has already being planned and would be collected from this area. An established technique to remove fluoride from water is available is the Nalgonda technique. This would be applied in this area to defluoride water in subsequent phases of this study.
