Study population was selected by stratified cluster random sampling, About 250 children were randomly selected from the schools of villages in each hoblis. Subsequently the samples from the sources of drinking water were collected for the estimation of Fluoride ion concentration in the water. A pilot study was carried out on field settings on randomly selected 100 students and changes were implemented where ever required, during the study.
