Abstract
With the expansion of certain types of industrialization into agricultural areas, fluorosis in livestock has become an important toxicologic problem in some places in the United States and many other countries. Fluorine has beneficial effects when ingested in small amounts, but toxic and adverse effects when ingested in excessive amounts. Many sources may contribute to the total fluorine intake of animals. Various factors influence biologic responses of livestock to ingested fluorides. Fluorosis can be correctly diagnosed and evaluated by qualified individuals. Some methods and procedures are helpful in alleviating fluorine toxicosis. Several programs may be used for settlements and solutions of fluorosis problems. Standards and a comprehensive guide for use in diagnosing and evaluating fluorosis in livestock has been compiled.

The onset of chronic fluorosis is insidious and may be confused with chronic debilitating diseases such as osteoarthritis . . .

Skeletal fluorosis with neurological complications
A case of skeletal fluorosis with spinal cord compression from Kekirawa following consumption of water with high fluoride content for about 20 years is described. The observations of other workers and the present case report show that more extensive field studies among vulnerable populations is indicated in this region. The need to

Skeletal fluorosis among Indians of the American Southwest
Presented are 20 cases of Southwestern American Indians having characteristic sclerotic bone changes caused by the ingestion of drinking water containing excessively great quantities of fluoride salts. The changes of skeletal fluorosis are described, and it is pointed out that the degree of change does not seem to correlate well

Involvement of Bmal1 and circadian clock signaling in chondrogenic differentiation of ATDC5 cells by fluoride.
Highlights Fluoride inhibited chondrocyte viability and delayed chondrocyte differentiation. Fluoride disrupted the circadian clock signaling pathway in ATDC5 cells. Overexpression of Bmal1 reversed the delayed chondrogenic differentiation induced by fluoride. Skeletal fluorosis causes growth plate impairment and growth retardation during bone development. However, the mechanism of how fluoride impairs chondrocyte

Fluoride toxicosis in immature herbivorous domestic animals living in low fluoride water endemic areas of Rajasthan, India: An observational survey
Susceptibility to fluoride toxicosis in the form of osteo-dental fluorosis was observed among 435 immature herbivorous domestic animals living in areas with less than 1.5 ppm fluoride in the drinking water. These animals included 78 buffaloes (Bubalus bubalis), 89 cattle (Bos taurus), 30 donkeys (Equus asinus), 21 horses (Equus caballus),

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.
