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.

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

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

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

Review of the Bartlett-Cameron survey: a ten year fluoride study.
Analysis of the data produced the following conclusions: 1. As was expected, dental fluorosis was significantly greater in Bartlett than in Cameron (all of the participants born and in continuous residence in Bartlett during the tooth formative period exhibited positive evidence of dental fluorosis). 2. The incidence of cardiovascular disease was higher

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.

"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 & 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

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

In Vitro Studies on Fluoride & Bone Strength
The "in vitro" research on fluoride and bone strength confirms what has repeatedly been found in animal and human studies: the more fluoride a bone has, the weaker the bone becomes. In an in vitro bone study, the researcher directly exposes a human or animal bone to a fluoride solution
