  • The effects of protein deficiency and fluoride on bone mineral content of rat tibia

    This study examined the effects of chronic protein deficiency and fluoride administration (10 mg/kg/day), separately or in combination, on rat tibia properties. Protein deficiency increased the bone fluoride concentration and reduced the bone mineral content (BMC) especially at the proximal or growing end which contains mainly cancellous bone. Fluoride administration

  • Addition of monofluorophosphate to estrogen therapy in postmenopausal osteoporosis: a randomized controlled trial

    INTRODUCTION: Treatment of osteoporosis with high-dose fluoride alone does not reduce fracture risk. We hypothesized that the antifracture efficacy of fluoride could be optimized by its use in low doses combined with an antiresorptive agent. EXPERIMENTAL SUBJECTS: Subjects included 80 women with postmenopausal osteoporosis who had been taking estrogen for at least 1

  • Effect of sodium fluoride on bone biomechanical and histomorphometric parameters and on insulin signaling and insulin sensitivity in ovariectomized rats

    Osteoporosis is a systemic disease characterized by bone degradation and decreased bone mass that promotes increased bone fragility and eventual fracture risk. Studies have investigated the use of sodium fluoride (NaF) for the treatment of osteoporosis. However, fluoride can alter glucose homeostasis. The aim of this study was to evaluate

  • Fluoride exposure may accelerate the osteoporotic change in postmenopausal women: animal model of fluoride-induced osteoporosis

    Carbonic anhydrase is a key enzyme for initiating the crystal nucleation, seen as “the central dark line” in the crystal structure in calcified hard tissues such as tooth enamel, dentin and bone. Both estrogen deficiency and fluoride exposure adversely affected the synthesis of this enzyme in the calcifying hard tissues.

  • The effects of fluoride on the bones and teeth from ICR-derived glomerulonephritis (ICGN) mice and ICR mice after subacute exposure

    Dental fluorosis and osteofluorosis from using drinking water contaminated with the fluoride ion (F) have been reported from many countries including the People’s Republic of China and India. Because fluoride is excreted by the kidney and the toxic effects of F are more severe when renal failure is present, Imprinting

  • 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.
