Abstract

1. Twenty-three cases of fluoride osteosclerosis are presented.

2. These cases were gathered from 170,000 roentgenographic examinations of the spine and pelvis of patients living in Texas and Oklahoma where many communities have excessive fluoride content in their drinking water.

3. In each case, adequate clinical examination failed to establish any relationship between the roentgenologic findings and clinical diagnosis of the patient’s condition.

4. Fluoride osteosclerosis developing in the patient exposed over a period of many years to fluorides as high as 8 ppm, causes no harmful changes.

5. Fluoride osteosclerosis is not evidenced roentgenographically in the patient drinking water with a fluoride content of less than 4 ppm.

6. In the patient presenting roentgen evidence of sclerosis of the bone, calcification of the sacrospinous and sacrotuberous ligaments is a distinct aid in the diagnosis of fluoride osteosclerosis.

  • [Two cases of skeletal fluorosis in the hand].

    Skeletal fluorosis is well known, particularly in the spine, pelvis and forearm. However, the hand may also be involved. The authors report two cases of this site in endemic areas in Senegal, after ingestion of large amounts of fluoride in the water. Fluorosis consisted of deforming metacarpal and phalangeal osteoperiotitis in one case

  • Excessive ingestion of fluoride and the significance of sialic acid: glycosaminoglycans in the serum of rabbit and human subjects

    The levels of sialic acid and glycosaminoglycans were explored in the sera of rabbit and human subjects who ingested fluoride and had clinical manifestation of fluorosis. Changes observed in the level of these chemical constituents in sera possibly reflect changes occurring in calcified and noncalcified tissues due to fluoride intoxication. The

  • Why did the ancient inhabitants of Palmyra suffer fluorosis?

    The skeletal remains uncovered from the 2nd and 3rd century underground tombs of Palmyra, Syria, retain traces of arthritis and mottled enamel. A brown discoloration was also observed in the teeth. In order to clarify that these facts can be related to fluorosis, the teeth excavated from Tomb C and

  • Bone and joint pathology in fluoride-exposed workers

    Clinical and radiological investigations were performed for 2,258 aluminum workers exposed to fluoride for an average of 17.6 yr (standard deviation = 7.6). Changes in bone and joints were presented in detail in three groups: (1) exposed up to 5 yr (135 cases), (2) exposed from 6-32 yr (1,463 cases),

  • Multiple myeloma-like spinal MRI findings in skeletal fluorosis: an unusual presentation of fluoride toxicity in human

    Endemic fluorosis is a worldwide environmental problem due to excessive fluoride, commonly due to increased drinking water fluoride levels but sometimes due to other sources such as food with high fluoride content. In India, 21 of the 35 states are known to have health problems associated with fluoride toxicity. The

  • 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.

  • 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.

  • Exposure Pathways Linked to Skeletal Fluorosis

    Excessive fluoride exposure from any source -- and from all sources combined -- can cause skeletal fluorosis. Some exposure pathways , however, have been specifically identified as placing individuals at risk of skeletal fluorosis. These exposure pathways include: Fluoridated Water for Kidney Patients Excessive Tea Consumption High-Fluoride Well Water Industrial Fluoride Exposure Fluorinated Pharmaceuticals (Voriconazole

  • Estimated "Threshold" Doses for Skeletal Fluorosis

    For over 40 years health authorities stated that in order to develop crippling skeletal fluorosis, one would need to ingest between 20 and 80 mg of fluoride per day for at least 10 or 20 years. This belief, however, which played an instrumental role in shaping current fluoride policies, is now acknowledged by the National Academy of Sciences (NAS) and other US health authorities to be incorrect.
