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.

Skeletal fluorosis and instant tea
Tea drinking remains popular in the United States and increasingly is suggested to promote health. We caution that skeletal fluorosis can result from consumption of excessive amounts of instant tea because of substantial fluoride levels in some commercial preparations.

Diagnosis and treatment of deforming osteoarthrosis in subjects in contact with fluoride compounds
A comparative study is presented of 378 workers with osteoarthrosis deformans (OD) contacting with fluorine compounds and in 106 patients with primary OD. The diagnostic criteria in these two categories of patients coincided. But the pain syndrome in the joints in professional fluorosis (PF) was associated with ossalgias (85%), tenderness

[Epidemiology and clinical study of endemic fluorosis in a village that has improved water for 40 years].
Objective: To investigate the control effect of water improvement for endemic fluorosis over a long period of time, the health status of the residents in the disease area and the restoration to health of endemic fluorosis patients. Methods: It was investigated that the water improvement lasting for 40 years and the rate

Fluorosis in Aden
The cases to be described here occurred in the Aden Protectorate where for the last 12 years mass screening of the chest to exclude pulmonary tuberculosis has been carried out. The patients had all drunk the brackish water from the wells, and the analysis of the water from a well

Clinical and hygienic evaluation of the combined effect of vibration and fluoride in humans
By L. Ya. Tartatovskaya, G.N. Samokhvalova, A.G. Antropov Medical Science Centre of Prophylactics and Protection of the Health Workers in Industrial Enterprises, Ekaterinburg, Russia. The study of the combined action of vibration and intense noise, muscular loads and cooling has made it possible to assess the probability of the development of vibration

"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.

Estimated "Threshold" Doses for Skeletal Fluorosis
For over 40 years health authorities stated that in order to develop crippling skeletal fluorosis, one would need to ingest between 20 and 80 mg of fluoride per day for at least 10 or 20 years. This belief, however, which played an instrumental role in shaping current fluoride policies, is now acknowledged by the National Academy of Sciences (NAS) and other US health authorities to be incorrect.

Skeletal Fluorosis in the U.S.
Although there has been a notable absence of systematic studies on skeletal fluorosis in the U.S., the available evidence indicates that the consumption of artificially fluoridated water is likely to cause skeletal fluorosis and other forms of bone disease in people with kidney disease and other vulnerable populations.
