Abstract
On the basis of 29 cases observed during 1948 to 1968, the author reports a disease termed periostitis deformans which was caused in alcoholics by sodium fluoride added to wine in concentrations of the order of 8 to 72 ppm. Four difference phases of the disease are described which are associated with osteosclerosis and osteoporosis. They lead to marked disability and may terminate fatatality.
Excerpt:
Fluoric Arthropathies: Around joints, thick marginal osteophytes develop. In some instances, they grow to such an extent as to block joint movement (‘blocking arthrosis’). The joint block can also be induced by calcification of the periarticular ligament. The most common sites of articular involvement are the hips, the sacroiliac, elbow and knee joints. In older persons, the vetebral column is commonly affected. Advanced stages of the disease show atrophy and ulceration of joint cartilage.

FRZB1 rs2242070 polymorphisms is associated with brick tea type skeletal fluorosis in Kazakhs, but not in Tibetans, China.
Skeletal fluorosis is a metabolic bone and joint disease caused by excessive accumulation of fluoride in the bones. Compared with Kazakhs, Tibetans are more likely to develop moderate and severe brick tea type skeletal fluorosis, although they have similar fluoride exposure. Single nucleotide polymorphisms (SNPs) in frizzled-related protein (FRZB) have

Dose-response relationship between skeletal fluorosis and fluoride in brick-tea
The dose-response relationship between fluoride in brick-tea and the prevalence of skeletal fluorosis (SF) in adults was studied to determine a safe upper limit for fluoride intake from brick-tea. In brick-tea drinking endemic fluorosis areas of the Tibetan pastoral areas of Sichuan province, cluster sampling was conducted of residents above age

Phosphorus supplements and fluorosis in cattle--a northern Australian experience.
Chronic fluoride toxicosis caused lameness, dental lesions and illthrift in an extensive beef cattle herd in northern Australia. Up to 15% of the herd was lame and the disease forced the culling of large numbers of cows. The source of fluoride was fertiliser-grade monoammonium and diammonium phosphate fed as part

Skeletal fluorosis in relation to drinking water, nutritional status and living habits in rural areas of Maharashtra, India
The present study was carried out during May 2010 to December 2011 in three villages which were randomly selected from Warora tehsil of Chandrapur district which is one of the endemic district of Maharashtra. . . . All the presently available ground water samples were collected and the mean fluoride concentration

"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.
