Why I changed my mind about water fluoridation.

Former Advocate To explain how I came to change my opinion about water fluoridation, I must go back to when I was an ardent advocate of the procedure. I now realize that I had learned, in my training in dentistry, only one side of the scientific controversy over fluoridation. I had been taught, and believed, that there was really no scientific case against fluoridation, and that only misinformed lay people and a few crackpot professionals were foolish enough to oppose it. I recall how, after

Nail and bone surface as biomarkers for acute fluoride exposure in rats.

Finally, in our 48-h study, we found that bone surface fluo- ride concentrations increased sooner than those in the nails and that they did not decline as they did in nails. This suggests that fluoride accumulation on the periosteal surface of the femur is faster and less likely to change as a function of time. For these reasons, we believe that this region of the femur is probably a better biomarker to confirm exposure to large doses of fluoride.

  Results Of the 44 vendors who attended the farmers market, 40 (91 per cent) were contacted. Inclusion of their family members brought the total subjects to 82; of these, 22 (27 per cent) reported a characteristic illness on the day of the market. All had onset of symptoms between 8:30 and 10:30 am. Of those ill, nausea was reported by 16 and vomiting by 13. Other symptoms included headache (5), cramps (4), dizziness (3), and diarrhea (2). Duration of the illness ranged from 1-24 hou
