The Department has commissioned and funded two research studies on fluoridation and health. "A Systematic Review of Public Water Fluoridation" published by the University of York in 2000 identified two studies, which found no significant association between thyroid disorders and water fluoridation, and one study with a positive association. However, the positive study looked at combined fluoride/iodine intakes and has not been published in a peer review journal.
"Water Fluoridation and Health" published by the Medical Research Council (MRC) in 2002 endorsed York's recommendation on the need for further research into fluoridation, but accorded low priority to further research on thyroid disorders. This was because the MRC judged the scientific plausibility of an association between water fluoridation and thyroid disease to be low.
We are committed to a continuing programme of research on the effects of fluoridation on health.
