    CASE DESCRIPTION A 45-year-old white male was found to have radiographic findings of a diffusely dense appendicular skeleton, mild trabecular thickening, and multiple thoracic compression fractures indicating structural weakness. Bone mineral density was above the expected range for his age on the lumbar spine and femoral neck. Social history was significant

  • Prophylactic fluoride treatment and aged bones.

    In a double-blind trial with monofluorophosphate (25 mg fluoride per day) given to 460 aged persons (237 treated, 233 control) for eight months no difference was observed in height, admission to hospital, or mortality. Fractures and exacerbation of arthrosis were more frequent in the fluoride group. Vertebral x-ray films showed

  • Three-year effectiveness of intravenous pamidronate versus pamidronate plus slow-release sodium fluoride for postmenopausal osteoporosis

    All currently available and approved therapies for osteoporosis inhibit bone resorption. But, despite their great value, antiresorptive agents are generally not associated with dramatic increases in bone mass. In light of these data, the aim of our prospective, placebo-controlled, randomized clinical trial, with a 3-year follow up, was to examine

  • Effects of dialysate calcium and fluoride on bone disease during regular hemodialysis

    A previous study indicated that, in patients maintained by hemodialysis, clinically and roentgenographically apparent bone disease appeared almost exclusively when the dialystate calcium concentration was less than 5.7 mg per 100 ml. In the present study, bone biopsy specimens from the iliac crest were studied at the beginning and end

  • Elevated serum fluoride concentrations in women are not related to fractures and bone mineral density

    Epidemiologic studies of the relations between drinking-water fluoride levels and bone mineral density (BMD) and fracture are characterized by disparate conclusions and an absence of information about individual circulating fluoride levels. This study relates serum fluoride concentrations, which reflect individual fluoride exposures, to BMD and bone fractures. Data are from

  • 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 & 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

  • Fluoride Reduces Bone Strength in Animals

    Most animal studies investigating how fluoride effects bone strength have found either a detrimental effect, or no effect. Few animal studies have found a beneficial effect. In fact, one of the few studies that found a beneficial effect was unable to be repeated by the same authors in a later

  • 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 in Water & Bone Fracture

    Current epidemiological evidence indicates that the margin of safety between the level of fluoride in water that does, and does not, increase the risk of fracture is insufficiently large to protect all members of society from fluoride-induced damage to bone.
