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.

  • Fluoride in synovial fluid, bone marrow, and cartilage in patients with osteoarthritis.

    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

  • Skeletal fluorosis from instant tea

    INTRODUCTION: Skeletal fluorosis (SF) can result from prolonged consumption of well water with >4 ppm fluoride ion (F(-); i.e., >4 mg/liter). Black and green teas can contain significant amounts of F(-). In 2005, SF caused by drinking 1-2 gallons of double-strength instant tea daily throughout adult life was reported in

  • Osteomalacia is associated with high bone fluoride content in dialysis patients

    Osteomalacia is now rarely observed in hemodialyzed patients since the prevention of aluminum intoxication and vitamin D deficiency. However, this disorder is still present and may be responsible for bone fractures. Fluoride overload is responsible for mineralization defects. We therefore prospectively measured the bone fluoride content in all dialysis osteomalacic

  • 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.

  • "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.

  • 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.
