Abstract
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 no difference. The free ionized fluoride levels in the plasma of the fluoride-treated group were still twice as high two months after treatment ended. Fluoride treatment in the prophylaxis of osteoporosis is not recommended unless there is simultaneous measurement of plasma ionized fluoride levels.

Environmental Fluoride 1977 by Rose & Marier
The Associate Committee on Scientific Criteria for Environmental Quality was established by the National Research Council of Canada in response to a mandate provided by the Federal Government to develop scientific guidelines for defining the quality of the environment. The concern of the NRC Associate Committee is strictly with scientific

Long-term fluoride therapy of postmenopausal osteoporosis
The benefit of sodium fluoride (NaF) in the therapy of osteoporosis is still controversial. For 3 years we monitored patients with postmenopausal osteoporosis subjected to a continuous treatment with 80 mg NaF/day and patients without fluoride treatment. Every 3 months peripheral total and trabecular bone densities were evaluated with high-precision

Total knee arthroplasty in a patient with skeletal fluorosis
Published reports on patients with skeletal fluorosis undergoing total knee arthroplasty are rare. Skeletal fluorosis is a chronic condition that occurs secondary to the ingestion of food and water that contain high levels of fluoride. Although fluorosis may be described as osteosclerotic and marble-like in appearance, features may also include

The effects of fluoridation on degenerative joint disease (DJD) and hip fractures
Fluoride strengthens bone, yet makes it more susceptible to fracture. If mechanical factors are important in DJD, an increased risk for DJD in communities where fluoride is consumed is also expected. Hip fractures and knee DJD joint replacements among those >65 years for 1991-1996 were compared between one community with

Bone mineral structure after six years fluoride treatment investigated by backscattered electron imaging (BSEI) and small angle x-ray scattering (SAXS): a case report
NaF, a bone formation stimulating agent, is used for the treatment of osteoporosis. Controversy exists concerning the quality of the newly formed bone and the antifracture effectiveness. We report about a 70 years old woman, who had received 50 mg NaF/d for about 6 years. Calcium or Vit D supplements

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.

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

Clinical Trials: Fluoride Treatment & Bone Fracture in Osteoporosis Patients
Due to its ability to increase bone mass, fluoride has been used as an experimental treatment for osteoporosis. The results, however, have generally been disastrous. Rather than prevent bone fractures in osteoporosis patients, fluoride therapy (at doses of 20-34 mg/day) was repeatedly found to increase fracture rates. One of the most

Fluoride Content of Bone Impairs Bone Quality
Water Fluoridation Increases the Fluoride Content of Bone "Fluoride analyses of the cadaver material from Kuopio revealed that fluoridation of drinking water increases the fluoride concentration in bone. In some individual cases the amount of fluoride in trabecular bone may rise to relatively high levels, notably in patients with impaired renal

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.
