Abstract
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 to four years and seven months. No excessively high concentrations of fluoride was found in any of these specimens.
From residents of a nonfluoridated area 15 various bone samples of 11 patients with different forms of arthritis and 2 patients who did not have arthritis were analyzed for fluoride content expressed in parts per 1,000,000 of ash. The fluoride concentration value in bone of the resident and nonresident fluoridated water areas was not statistically different.
A careful review of the radiograms of both these groups, along with the bone fluoride studies, fails to reveal any relation between various forms of arthritis and the ingestion of fluoridated water as recommended by the health authorities.

Fluoride in synovial fluid, bone marrow, and cartilage in patients with osteoarthritis.
The aim of this study was to comp are the concentrations of fluoride (F) in cartilage, bone marrow, and synovial fluid taken from patients with osteoarthritis (OA). We also determined the correlation between OA risk factors, including age, sex, obesity, and hypertension, and F concentrations in the studied materials. The

Industrial fluorosis [Franke et al.]
This is a review of findings on workers in an aluminum plant with industrial fluorosis. Early signs of the disease are nocturnal back pains and restriction of the rotation of the trunk. Stage I of the disease usually occurs after 10 years, stage II after 15 years and stage III

Human vertebral bone: relation of strength, porosity, and mineralization to fluoride content
Radiographically normal vertebral bone cylinders from 80 male subjects were tested mechanicallly by static compression and analyzed for porosity, fluoride and ash content. As a group, they had low fluoride content, suggesting little prior intake, consonent with this geographic area. Nevertheless, increasing levels of fluoride were associated with bulkier bone,

The effect of drinking water fluoridation on the fluoride content, strength and mineral density of human bone
The effect of drinking water fluoridation on the fluoride content of human bone, on cancellous bone strength and on the mineral density of bone was studied by analysing 158 autopsy samples of the anterior iliac crest from persons from two different areas. In the samples from the town of Kuopio,

Hip fracture incidence not affected by fluoridation. Osteofluorosis studied in Finland
Iliac crest biopsies were taken from patients with hip fracture from a low-fluoride area (less than 0.3 ppm), from an area with fluoridated drinking water (1.0-1.2 ppm), and from a high-fluoride area (greater than 1.5 ppm). Fluoride content analysis and histomorphometry of bone were performed. The hip fracture incidence during

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.

"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 & 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.
