  • Fluoridation and the rheumatic diseases: a comparison of rhematism in Watford and Leigh

    (1) A population sample in the town of Watford, Hertfordshire, has been examined clinically, radiologically, and serologically to determine the prevalence of chronic rheumatic diseases. A comparison has been made with a population sample in Leigh, Lancashire. The water supply in Watford had been fluoridated during the previous 5 years,

  • A roentgenologic study of a human population exposed to high-fluoride domestic water; a ten-year study

    As shown in Table 1, a limited number of participants from both Bartlett and Cameron showed some degree of roentgenographic bone change but, in general, these changes were minimal. There was a larger number with no observable change in the ten-year interval, a fact disregarded or unreported in most fluoride

  • Medical aspects of excessive fluoride in a water supply

    A 10-year study of 116 persons in Bartlett and 121 in Cameron, Tex., was conducted to determine if prolonged exposure to fluoride in the water supply of Bartlett had produced detectable physiological effects. Bartlett's water contained about 8 p.p.m. F until 1952, when an experimental defluoridation unit was installed, reducing the

  • Fluoride pharmacokinetics and changes in lumbar spine and hip bone mineral density

    Debate about the use of fluoride for the treatment of vertebral osteoporosis has centered not only on whether fluoride treatment decreases vertebral fractures, but also the interindividual vertebral bone mineral density (BMD) response, the potential for nonvertebral fractures, as well as side effects and tolerability. These effects may be dose

  • Fluoride exposure and bone status in patients with chronic intestinal failure who are receiving home parenteral nutrition

    BACKGROUND AND OBJECTIVE:  Metabolic bone disease is frequent in chronic intestinal failure. Because fluoride has a major effect on bones, the status of both fluoride and bone was studied in long-term home parenteral nutrition (HPN) patients. DESIGN:  We studied 31 adults aged (x +/- SD) 56.3 +/- 15.1 y, mainly

  • "Pre-Skeletal" Fluorosis

    As demonstrated by the studies below, skeletal fluorosis may produce adverse symptoms, including arthritic pains, clinical osteoarthritis, gastrointestinal disturbances, and bone fragility, before the classic bone change of fluorosis (i.e., osteosclerosis in the spine and pelvis) is detectable by x-ray. Relying on x-rays, therefore, to diagnosis skeletal fluorosis will invariably fail to protect those individuals who are suffering from the pre-skeletal phase of the disease. Moreover, some individuals with clinical skeletal fluorosis will not develop an increase in bone density, let alone osteosclerosis, of the spine. Thus, relying on unusual increases in spinal bone density will under-detect the rate of skeletal fluoride poisoning in a population.

  • Fluoride & Osteoarthritis

    While the osteoarthritic effects that occurred from fluoride exposure were once considered to be limited to those with skeletal fluorosis, recent research shows that fluoride can cause osteoarthritis in the absence of traditionally defined fluorosis. Conventional methods used for detecting skeletal fluorosis, therefore, will fail to detect the full range of people suffering from fluoride-induced osteoarthritis.

  • Skeletal Fluorosis: The Misdiagnosis Problem

    It is a virtual certainty that there are individuals in the general population unknowingly suffering from some form of skeletal fluorosis as a result of a doctor's failure to consider fluoride as a cause of their symptoms. Proof that this is the case can be found in the following case reports of skeletal fluorosis written by doctors in the U.S. and other western countries. As can be seen, a consistent feature of these reports is that fluorosis patients--even those with crippling skeletal fluorosis--are misdiagnosed for years by multiple teams of doctors who routinely fail to consider fluoride as a possible cause of their disease.
