Abstract
(1) A population sample in the town of Watford, Hertfordshire, has been examined clinically, radiologically, and serologically to determine the prevalence of chronic rheumatic diseases. A comparison has been made with a population sample in Leigh, Lancashire. The water supply in Watford had been fluoridated during the previous 5 years, whereas in Leigh the water contained only negligible amounts of fluoride.
(2) There was no increased prevalence of rheumatoid arthritis, osteo-arthrosis, spondylitis, gout, or disk degeneration, and indeed, rheumatic complaints as a whole and incapacity due to rheumatism were significantly less in Watford than in Leigh.
(3) The prevalence of positive sheep cell agglutination titres and latex fixation titres in Watford was significantly lower than expected.
(4) There was a diminished prevalence of osteoporosis as judged from hand and cervical radiographs in the Watford females compared with those in Leigh, that in males being similar in each area.

A roentgenologic study of a human population exposed to high-fluoride domestic water; a ten-year study
As shown in Table 1, a limited number of participants from both Bartlett and Cameron showed some degree of roentgenographic bone change but, in general, these changes were minimal. There was a larger number with no observable change in the ten-year interval, a fact disregarded or unreported in most fluoride

Medical aspects of excessive fluoride in a water supply
A 10-year study of 116 persons in Bartlett and 121 in Cameron, Tex., was conducted to determine if prolonged exposure to fluoride in the water supply of Bartlett had produced detectable physiological effects. Bartlett's water contained about 8 p.p.m. F until 1952, when an experimental defluoridation unit was installed, reducing the

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

Long term effects of sodium fluoride in osteoporosis
Our results demonstrate that the bone response to NaF treatment is a phase process: an increase in bone turnover is combined with an osteomalacia-like reaction during the first year of treatment. These metabolic observations are in close agreement with the histomorphometric data of Olah, Reutter and Schenk. By comparing the

Fluoridation of public water supplies and its relation to musculoskeletal diseases
The fluoride content in parts per 1,000,000 of ash was estimated in 18 various bone samples from 14 patients with different forms of arthritis and from 1 patient who did not have arthritis, all of whom had ingested fluoridated water for a period ranging from three years and five months

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.

"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.
