Abstract
Objective To probe into X-ray, CT and MRI manifestations of bone turnover in skeletal fluorosis and diagnostic values of different examination technologies. Methods Comparisons and analyses were made on the imaging manifestations of bone turnover in 28 reported cases with skeletal fluorosis. Results All 28 cases had dental fluorosis of different degrees. The chief symptoms included arthralgia and aching muscle pains in four limbs; 13 cases had joint motion limitation and dysfunction, 28 cases had spinal pain and 26 cases (92.85%) had pain in the lumbar region and legs. As to the imaging manifestations, 17 cases mainly had hyperostosis and 11 cases mainly had osteopenia; 5 had fuzzy bone trabecula, 9 loosening of cortical bone and 19 sclerosis of cancellous bone; 7 cases were complicated by biconcave deformity of vertebral body and 6 cases by pelvic deformity; 4 cases manifested the formation of false fracture line, and 7 cases manifested disorder of bone growth and development. Conclusions: MRI may distinctly display early changes of bone turnover in patients with skeletal fluorosis with high diagnostic sensitivity.

[Ossification of ligament and tendon attached around the elbow joint in diagnosis of skeletal fluorosis].
Objective: To probe into the significance of osteosis of the junctions of ligaments and tendons around elbow joints for the diagnosis of skeletal fluorosis. Methods: Analyses were conducted on X-ray signs of elbow joints in 23 cases with skeletal fluorosis and fluoridated elbow joints identified in March 2011 in an

Industrial fluorosis [Boillat et al.]
43 potroom workers (aluminium industry) with fluorosis have been compared with 18 foundry workers of the same age, but who had never been exposed to fluorides. Clinical examination revealed a higher incidence of articular pain and limitation of motion in the exposed group. The diagnosis of fluorosis is not only

An epidemiological study of skeletal fluorosis in some villages of Chandrapur District, Maharashtra, India
Fluorosis is an important public health problem in certain parts of India. Chandrapur is one of the fluorosis endemic district of Maharashtra. An investigation was undertaken in three villages of study area to assess the clinical symptoms of skeletal fluorosis and in turn to find out the severity of the

Total knee arthroplasty in a patient with skeletal fluorosis
Published reports on patients with skeletal fluorosis undergoing total knee arthroplasty are rare. Skeletal fluorosis is a chronic condition that occurs secondary to the ingestion of food and water that contain high levels of fluoride. Although fluorosis may be described as osteosclerotic and marble-like in appearance, features may also include

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

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.

Skeletal Fluorosis Causes Bones to be Brittle & Prone to Fracture
It has been known since as the early as the 1930s that patients with skeletal fluorosis have bone that is more brittle and prone to fracture. More recently, however, researchers have found that fluoride can reduce bone strength before the onset of skeletal fluorosis. Included below are some of the

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.
