Abstract
A case of extensive fluoride osteosclerosis is presented because of its roentgenographic similarity to carcinoma of the prostate with widespread bony metastasis. Roentgenographic manifestation of the effects of fluoride in human bones occurs only rarely and is infrequently recognized. Although no treatment is indicated in this condition, it should be acknowledged because of the previously mentioned similarity to carcinoma of the prostate and its benign clinical course.

[Study on determinationing the bone mineral content as diagnostic value for occupational fluorosis].
The results of determination of the bone density of 194 workers exposed to fluorine by SPA-III type osteodensimeter were compared with people unexposed to fluorine, and with the results of diagnosing the fluorosis by X-ray. (1) The abnormal bone cortex thickness and density rate in the people exposed to fluorine

Excessive ingestion of fluoride and the significance of sialic acid: glycosaminoglycans in the serum of rabbit and human subjects
The levels of sialic acid and glycosaminoglycans were explored in the sera of rabbit and human subjects who ingested fluoride and had clinical manifestation of fluorosis. Changes observed in the level of these chemical constituents in sera possibly reflect changes occurring in calcified and noncalcified tissues due to fluoride intoxication. The

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

Endemic fluorosis with neurological complications in a Hampshire man
We describe below a case of skeletal fluorosis occurring in a Hampshire man who presented with neurological complications, and whose condition was appreciably improved by operation. We believe that this is the first case of its kind to be reported from Britain, and also the first case of skeletal fluorosis

Radiological modifications of the skeletal system among aluminum smelter workers: A 15 year retrospective study
Previously by the time skeletal fluorosis among aluminum smelter workers due to high fluoride exposure was diagnosed numerous cases of bone fluorosis had already reached stages II and III according to Roholm. Today, as a result of improved working conditions and continuous health care, the picture has changed. This paper

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.

Fluoride & Rheumatoid Arthritis
The symptoms of skeletal fluorosis can closely resemble rheumatoid arthritis (RA), and thus individuals with fluorosis can "easily be mistaken" as having RA. In addition, clinical research on fluoride-treated osteoporosis patients has found that fluoride exposure can exacerbate pre-existing RA, and recent research shows that the levels of fluoride found in the blood of the general population (19-57 ppb) are sufficient to effect an enzyme (15-lipoxygenase) implicated in the inflammatory process of RA.

Symposium on the non-skeletal phase of chronic fluorosis: The Joints
Of 300 patients with endemic skeletal fluorosis 187 (110 children and 77 adults) showed evidence of arthritis. The spine, especially its cervical portion, appeared to be mainly involved; elbow, hip and knee joints followed next in order.
