Jun 1, 2001 EDITOR-The systematic review by McDonagh et al indicates that the benefits and risks of water fluoridation balance each other in that a median of six people would need to receive ...fluoridated water for one to benefit while six people would have to be exposed to it for one additional person to develop dental fluorosis. 1 It also shows that in artificially fluoridated areas on average 48% of the population has this condition. Since dental fluorosis, whether of aesthetic concern or not, is the first visible sign of poisoning by fluoride, which is as toxic as arsenic and lead, this shows that about half the population in these areas is suffering from some degree of harm. Jun 1, 2001 EDITOR-Your comments in "This week in the BMJ" and the editorial by Hausen treated the study by Phipps et al on community water fluoridation, bone mineral density, and fractures, which you published alongside the systematic review of water fluoridation by McDonagh et al, as introducing new evidence that should alleviate remaining concerns about the safety of fluoridation. 1-3 The paper by Phipps et al, which seemed to show a slightly lower risk of fractures, had been fully accounted for in the systematic review by McDonagh et al, where it achieved the lowest rating (high risk of bias), in common with all but one of the studies on bone problems in the world literature.
