Introduction
Generally about half of the fluoride absorbed is deposited in bone. It was found in Finland (1) that the fluoridation of a water supply greatly increased the rate of fluoride accumulation in bone, from a mean of 11 ppm annually in low-fluoride areas to a mean of 44 ppm in the fluoridated people. In a warmer climate with a very 'soft' water supply the rate of increase may be more rapid. In a pilot study in Melbourne (2) the annual fluoride concentration increase in alveolar bone in
Introduction
In 1987, Moolenburgh (1) stated: 'I am absolutely convinced that fluoride is an immune suppressive substance.' He came to that conclusion following double-blind clinical tests which showed that there were many adverse reactions resulting from drinking fluoridated water.
In 1987, Sutton (2) advanced the hypothesis that, as a result of the normal resorption of bone containing a high concentration of fluoride (which forms in those who habitually drink fluoridated water) (3), the rele
"Fluoride is one of the most toxic inorganic chemicals in the Earth's crust, but it is believed that at a concentration of 1ppm, or 1m g/mL in public water supplies, and at the concentrations used in dental preparations, it is both safe and beneficial to teeth. However, with increasing experience, doubts about both safety and efficacy have arisen. While there is evidence of harm to the stomach, kidneys, thyroid, bones and teeth at higher concentrations, evidence for harm at concentrations around
