Abstract

The fluoride content in parts per 1,000,000 of ash was estimated in 18 various bone samples from 14 patients with different forms of arthritis and from 1 patient who did not have arthritis, all of whom had ingested fluoridated water for a period ranging from three years and five months to four years and seven months. No excessively high concentrations of fluoride was found in any of these specimens.

From residents of a nonfluoridated area 15 various bone samples of 11 patients with different forms of arthritis and 2 patients who did not have arthritis were analyzed for fluoride content expressed in parts per 1,000,000 of ash. The fluoride concentration value in bone of the resident and nonresident fluoridated water areas was not statistically different.

A careful review of the radiograms of both these groups, along with the bone fluoride studies, fails to reveal any relation between various forms of arthritis and the ingestion of fluoridated water as recommended by the health authorities.

    The aim of this study was to comp are the concentrations of fluoride (F) in cartilage, bone marrow, and synovial fluid taken from patients with osteoarthritis (OA). We also determined the correlation between OA risk factors, including age, sex, obesity, and hypertension, and F concentrations in the studied materials. The

    This is a review of findings on workers in an aluminum plant with industrial fluorosis. Early signs of the disease are nocturnal back pains and restriction of the rotation of the trunk. Stage I of the disease usually occurs after 10 years, stage II after 15 years and stage III

  • Effects of fluoride on bone in Finland. Histomorphometry of cadaver bone from low and high fluoride areas

    In three different areas of Finland, fluoride in bone and its effect on the histomorphometry of trabecular bone was studied. Bone samples were taken from cadavers from a low-fluoride area (fluoride concentration under 0.3 ppm), an area with fluoridated drinking water (1.0-1.2 ppm) and a high-fluoride area (over 1.5 ppm).

  • Fluoride and strontium accumulation in bone does not correlate with osteoid tissue in dialysis patients

    BACKGROUND: Osteomalacia is now a rare disease in dialysis patients in developed countries since the withdrawal of aluminium overload. The involvement of fluoride and strontium in the pathogenesis of the disease has been suggested. The aim of this study was to investigate a possible association between osteomalacia in dialysis patients

  • Effects of fluoride on bone metabolism in patients with hemodialysis

    The maior pathway of fluoride elimination from the human body is the kidney. The discharge of fluoride into urine depends on the clearance of the kidney. Fluoride in serum of hemodialysis patients is higher than that of healthy subjects. Fluoride is not reduced sufficiently with hemodialysis. Those patients are in

  • 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.

  • "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.
