Abstract
The Assam region of NE India has been recognized only recently as a fluoride-affected area. Surveys indicate that one-seventh of the 700,000 people in the Karbianglong district of Assam have either dental or skeletal fluorosis. The high concentration of fluoride in the water resources in some localities such as the Ramsapathar (>20.6 mg/L) and Lungnit (>15.4 mg/L) areas of the district are of great concern. In this report we present available information concerning the waterborne fluoride scenario of Karbianglong.

Fluorosis and osteomalacia
Clinical history A 30-year-old taxicab driver presented with a 1-year history of low back pain radiating into the posterior aspect of both legs, stiffness during inactivity, and proximal upper and lower limb myalgia. Symptoms were poorly controlled with acetaminophen. The medical history was unremarkable. The patient was a vegetarian, smoked 5

Endemic fluorosis: a study of the factors involved in the production of mottled enamel in children and severe bone manifestations in adults
Summary and Conclusions A detailed study of the factors involved in the production of "mottled enamel" in children and severe bone manifestations in adults; as a result of the ingestion of fluorides in drinking water, has been made during the last three years. This study revealed: 1. "Mottled enamel" in children was

Spirometry changes due to prolonged exposure to high level of fluoride in drinking water
Introduction: fluorosis is dental and skeletal tissue changes due to increase fluoride exposure this can also result in systemic and biochemical changes. Pulmonary involvement is established as a result of toxic exposure to inhaled fluoride however animal studies have shown that chronic fluorosis causes by ingested fluoride can cause marked

Skeletal Fluorosis: A Case of Inhalant Abuse Leading to a Diagnosis of Colon Cancer.
Abstract Skeletal fluorosis is a long-term bone disease that develops when prolonged fluoride toxicity leads to osteosclerosis and bone deformities that result in crippling pain and debility. The disease is endemic to many countries due to environmental or industrial exposures. However, rare cases in the United States have been reported from

Vitamin D deficiency, rickets, and fluorosis in India
Data on the vitamin D status of the populations in a tropical country like India have seldom been documented. Vitamin D deficiency is presumed to be rare. Population studied by the author and others in the country has proved otherwise. Studies were carried out to document the dietary habits, serum

"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.

Fluoridation, Dialysis & Osteomalacia
In the 1960s and 1970s, doctors discovered that patients receiving kidney dialysis were accumulating very high levels of fluoride in their bones and blood, and that this exposure was associated with severe forms of osteomalacia, a bone-softening disease that leads to weak bones and often excruciating bone pain. Based on

Fluoride & Spinal Stenosis
Spinal stenosis is a narrowing of the spaces in the spine that results in pressure being placed on the spinal cord and/or nerve roots. Although stenosis can develop without symptoms, it may produce numbness, tingling, pain and difficulty in walking, as well as a heavy/tired feeling in the legs. It is estimated that 250,000 to 500,000 Americans currently have symptoms of spinal stenosis. Skeletal fluorosis is one cause of stenosis.
