Abstract
We report a case of spinal cord compression in a Mexican immigrant due to vertebral osteosclerosis from chronic fluoride intoxication. Endemic fluorosis is acquired through drinking water. Groundwater sources with high fluoride content occur worldwide. The epidemiology, metabolism, and clinical features of fluorosis are reviewed. Greater physician awareness of this entity is important to identify correctly patients with this unusual and potentially devastating clinical disorder.

Equine dental and skeletal fluorosis induced by well water consumption.
Two horses that consumed well water with high fluoride content exhibited clinical signs of chronic dental and skeletal fluoride toxicosis and were later euthanized and autopsied. Both horses had degenerative disease of multiple joints and multiple dental defects. Elevated fluoride concentrations were found in bone and tooth samples of both

Combined effects of diets with reduced calcium and phosphate and increased fluoride intake on vertebral bone strength and histology in rats
Ingested fluoride is incorporated into bone apatite and can affect the structural integrity of bone. Fluoride absorption in the gut and incorporation into bone is affected by the presence of other ions, including calcium. We hypothesized that a low calcium phosphate diet combined with high fluoride intake would have independent

Fluoride Contamination Studies in Belchampa- Pratappur Villages of Garhwa District Jharkhand.
Belchampa-Pratappur villages about 8 Kms towards East from district head-quarter Garhwa has been undertaken to study the groundwater quality, especially fluoride contamination. These places are situated on the border of the Garhwa and Palamu district. Bishrampur is the prominent place lying to about 11 km east of area under consideration.

Multiple painless masses: periostitis deformans secondary to fluoride intoxication
Diagnosis The differential diagnosis based on the imaging findings included ossification of subperiosteal hematomas, ectopic calcification in the setting of a connective tissue disorder, and periostitis deformans secondary to fluoride intoxication. Laboratory assays were requested by the patient’s rheumatologist, which were notable for a mildly elevated alkaline phosphatase level (216 U/L,

Effects of smoking, use of aluminum utensils, and tamarind consumption on fluorosis in a fluorotic village of Andhra Pradesh, India
A field study was undertaken to determine effects of tamarind, the use of aluminium (Al) cooking utensils, and smoking on dental and skeletal fluorosis in the randomly selected fluoride (F) endemic village of Buttlapally in the Nalgonda District, Andhra Pradesh, India, where the F level in the drinking water is

"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.
