A survey was conducted in the remote area of Laxmisagar village of Simlapal Block, Bankura District, West Bengal, India, of the fluoride (F) concentration in ground water and dental fluorosis in children, 66 boys and 83 girls, aged 6 – 10 yr. The ground water F concentration range was 0.25-9.30 mg F/L and the mean 2.02 mg F/L. Using Dean’s Index, the severity of dental fluorosis tended to increase with age, particularly for girls but the result was not significant (boys: r=0.474, p=0.893; girls: r=0.949, p=0.146). In the >10 yr groups, severe dental fluorosis was present in 15.79% of boys and 35% of girls. Copyright © 2013 The International Society for Fluoride Research Inc.
