Conclusions
Although it is well known that the ingestion of high levels of fluoride can give rise to severe lesions in the skeletal tissues, such effects have never been found radiographically in persons using a water supply, containing less than 4 p.p.m fluorlde throughout life.
A histological study of thirty ribs taken from deceased residents of a region where the drinking water contained 1.9 p.p.m. fluoride revealed no changes characteristic of skeletal fluorosis.
Although even at a level of 1 p.p.m. fluoride in the drinking water, the concentration of the element in bone increases with age, the level reached after lifelong ingestion of water containing 1 p.p.m. fluoride would be appreciably lower than that associated with the condition of skeletal fluorosis.

Non-Endemic Skeletal Fluorosis: Causes And Associated Secondary Hyperparathyroidism (Case Report and Literature Review).
Highlights Fluorocarbon “huffing” is an under-appreciated cause of skeletal fluorosis (SF) We present a SF case with hyperparathyroidism, osteosclerosis, and osteomalacia SF may go undetected due to variation in symptoms, radiology, and biochemistry Dietary calcium, prior bone health, and skeletal F exposure influence SF features SF is common in

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

Effects of fluoride on bone in Finland. Histomorphometry of cadaver bone from low and high fluoride areas
In three different areas of Finland, fluoride in bone and its effect on the histomorphometry of trabecular bone was studied. Bone samples were taken from cadavers from a low-fluoride area (fluoride concentration under 0.3 ppm), an area with fluoridated drinking water (1.0-1.2 ppm) and a high-fluoride area (over 1.5 ppm).

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

Normal age-related changes in fluoride content of vertebral trabecular bone--relation to bone quality
In several clinical osteoporosis studies, fluoride treatment has been shown to have a positive effect on bone mass but without a concomitant decrease in vertebral fracture rate. In contrast, some studies have shown that increases in spinal BMD are also paralleled by decreased vertebral fracture incidence. We have previously demonstrated,

"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.

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 Magnifies Impact of Repetitive Stress on Joints
Research has repeatedly found that fluoride's effect on the skeleton is most pronounced in the bones and joints that undergo the greatest strain. Indeed, both the symptoms of fluorosis (i.e., joint pain and stiffness) as well as the radiological findings (e.g., exostoses, interosseuous membrane calcification) have been found to occur earliest, and most severely, in the joints
