Abstract
This paper deal in the regressive analysis on the basis of fluorine content of supply water and morbidity of enamel fluorosis. The morbidity sharp increased with increase of the fluorine content in the range of 0.4-1.0 mg/l. Furthermore, the relationship between the prevalence rate of skeletal fluorosis and the [fluorine] content became linear regression, so that the safe threshold values of fluorine content in supply water are regarded as less than 0.5 mg/l, it seems better.

Fluoride contamination of groundwater and its threat to health of villagers and their domestic animals and agriculture crops in rural Rajasthan, India.
In India, Rajasthan is the largest state and has seven divisions, namely Ajmer, Bharatpur, Bikaner, Jaipur, Jodhpur, Kota and Udaipur. Villagers of these regions, generally, used groundwater for drinking and irrigation purposes. The basic sources of groundwater in rural areas are hand pumps, step wells and borewells. Water of most

Clinical symptoms of dental and skeletal fluorosis in Gadag and Bagalkot Districts of Karnataka.
An investigation was undertaken in six endemic villages of Mundargi taluk of Gadag district and two of Hungund taluk of Bagalkot district to assess the clinical symptoms of both dental and skeletal fluorosis and in turn to find out the severity of the disease. A check list developed with the help of

A Brief and Critical Review of Chronic Fluoride Poisoning (Fluorosis) in Domesticated Water Buff aloes (Bubalus bubalis) in India: Focus on its Impact on Rural Economy.
In the rural areas of India, fl uoridated drinking water, industrial fluoride pollution and fluoride rich feed phosphate supplements are the major sources of fluoride exposure for domesticated water buffaloes (Bubalus bubalis). However, the fluoridated drinking groundwater is the commonest and principal source of fluoride exposure for these ruminants. Chronic

Efficacy of Calcium-Containing Eggshell Powder Supplementation on Urinary Fluoride and Fluorosis Symptoms in Women in the Ethiopian Rift Valley.
Dietary calcium binds Fluoride (F), thus preventing excess F absorption. We aimed to assess the efficacy of supplementing calcium-containing Eggshell Powder (ESP) on F absorption using urine F excretion and on fluorosis symptoms. In total, 82 women (41 Intervention Group, IG; 41 Control Group, CG) were recruited; overall, 39 in

Distribution of fluoride contamination in drinking water resources and health risk assessment using geographic information system, northwest Iran.
Highlights Fluorosis is a considerable health problem worldwide. High concentrations fluoride above 3 mg l?1 may cause dental and skeletal fluorosis. HQ indicated health risk assessment in relation to F- concentration for children and adults were significant. The fluoride contamination must be reduced in this study area to decrease endemic

"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.

Racial Disparities in Dental Fluorosis
In 2005, the Centers for Disease Control published the results of a national survey of dental fluorosis conducted between 1999 and 2002. According to the CDC, black children in the United States have significantly higher rates of dental fluorosis than either white or Hispanic children. This was not the first time that black children were found to suffer higher rates of dental fluorosis. At least five other studies -- dating as far back as the 1960s -- have found black children in the United States are disproportionately impacted by dental fluorosis.

Fluoride Magnifies Impact of Repetitive Stress on Joints
Research has repeatedly found that fluoride's effect on the skeleton is most pronounced in the bones and joints that undergo the greatest strain. Indeed, both the symptoms of fluorosis (i.e., joint pain and stiffness) as well as the radiological findings (e.g., exostoses, interosseuous membrane calcification) have been found to occur earliest, and most severely, in the joints
