  • Marked decrease in trabecular bone quality after five years of sodium fluoride therapy--assessed by biomechanical testing of iliac crest bone biopsies in osteoporotic patients

    Sodium fluoride has for more than 2 decades been a commonly used therapeutic agent for established osteoporosis because of a repeatedly documented anabolic effect on trabecular bone mass. Recently, however, three controlled trials have failed to demonstrate any therapeutic advantage of NaF over placebo with respect to vertebral fracture rate.

  • Mechanical properties and density of bone in a case of severe endemic fluorosis

    Mechanical properties of 25 standardized specimens of compact bone from a 45-year-old man with extreme endemic fluorosis were compared with similar specimens of nonfluorotic bone. Data from dry and wet tested specimens were compared. Tensile strength, strain, energy absorbed to failure, and modulus of elasticity were reduced in fluorotic specimens

  • Well water fluoride, dental fluorosis, bone fractures in the Guadiana Valley of Mexico

    In the Guadiana Valley (the city of Durango and its surroundings in northwestern Mexico), the drinking water supply comes from underground wells and is characterized by a high content of fluoride. In this study, a quantitative assessment of dental fluorosis was made in the school age (6-12 years) and adult

  • [Generalized osteopathy with pathological fractures in a patient with long-term exposure to fluorine-containing plastics].

    In a 68-year-old man with a painful syndrome of the lower extremities which began at the age of 64 years, workup revealed a generalized osteopathy with sclerosis of the axial skeleton and osteopenia at the extremities associated with pathologic fractures. The occupational history showed exposure to several synthetics such as

  • Industrial Fluorosis [Carnow et al.]

    SUMMARY: In 1242 apparently healthy and actively employed workers of a Canadian aluminum facility, the history of musculoskeletal symptoms, of the incidence of fractures, of neck and back surgery, as well as the x-ray findings were reviewed. A highly significant relationship of exposure to fluoride was established with the frequency

  • The Relationship Between Fluoride, Bone Density, and Bone Strength

    Although fluoride has generally been found to reduce the bone density of cortical bone, it is well documented that fluoride can increase the density of trabecular bone (aka cancellous bone). Trabecular  bone is the primary bone of the spine, whereas cortical bone is the primary bone of the legs and arms. While increases in

  • Fluoride & Spontaneous Hip Fractures in Osteoporosis Patients

    Due to its ability to increase vertebral bone mass, fluoride has been used as an experimental treatment for osteoporosis (doses > 20 mg/day). Fluoride treatment, however, proved far more harmful than beneficial. Not only was fluoride therapy shown to increase fracture rates among the treated patients, it was also found to

  • 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.

  • 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.

  • Fluoride Reduces Bone Strength Prior to Onset of Skeletal Fluorosis

    The majority of animal studies investigating fluoride's impact on bone strength have found that fluoride has either no effect, or a detrimental effect, on bone strength. Importantly, several of the animal studies that have found fluoride reductes bone strength have reported that this reduction in strength occurs before signs of skeletal fluorosis
