§ Mr. BradyTo ask the Secretary of State for Health what estimate he has made of the percentage of the population affected by dental fluorosis in areas where the water supply is(a) fluoridated and (b) not-fluoridated. [94248]
§ Mr. LammyThe report, "A Systematic Review of Water Fluoridation", published by the University of York in October 2000, estimated that the prevalence of dental fluorosis at a water fluoride level of 1.00 parts per million was 48 per cent. for all grades of fluorosis, including those which can only be identified by close professional examination and 12.5 per cent. for fluorosis of aesthetic concern.
36WIt should be noted that these figures include all enamel marks, whether from fluoride or not. Information is not held centrally on the prevalence of dental fluorosis in areas where the water supply is not artificially fluoridated.
