Abstract
Earlier observations and a review on endemic fluorosis in the Bhatinda District of Punjab were published in 1961 [this Bulletin, 1962, v. 37, 243] and the object of the present paper “is to summarize our epidemiological work done over three years and to emphasize the importance of this work from the social and preventive aspects”.
The physiography of the Bhatinda District is described with the inclusion of a map. The method of survey is shortly stated. The district has an approximate population of 58, 000 in which 2, 282 persons over the age of 30 were critically examined for the presence of skeletal fluorosis. This condition was diagnosed in 63 persons and of these 27 showed neurological complications. In addition a high incidence of dental fluorosis in children was found. Much detail is given of the patients with skeletal fluorosis-their symptoms, clinical signs and the results of laboratory investigations of the cerebrospinal fluid and serum chemistry. There are X-ray photographs of some of the advanced cases of skeletal fluorosis.
A table presents data on the fluorine content of soil, water, blood and bone in relation to individual cases of skeletal fluorosis.
The social and preventive aspects are discussed briefly.

[Relationship between fluoride exposure, orthopedic injuries and bone formation markers in patients with coal-burning fluorosis].
Chronic exposure to fluoride is a public health problem worldwide. We explored the relationship between fluoride exposure, orthopedic injuries and bone formation markers alkaline phosphatase (ALP), bone Gla protein (BGP) in participants with coal-burning fluorosis in Hehua Village (coal-burning fluorosis endemic area) in Zhijin County of Guizhou Province and Zhangguan

Studies on fluorosis in Mehsana District of North Gujarat.
A survey was conducted in eighteen fluoride endemic villages in Mehsana District of North Gujarat (India). The individuals afflicted with fluorosis were examined for apparent mottled teeth and skeletal complications. Samples of urine and blood of these individuals along with drinking water were collected and compared with samples obtained from

Fluoride exposure altered metabolomic profile in rat serum
Highlights 58 NEG and 73 POS metabolites were altered in F-treated 3 weeks rat serum. 126 NEG and 70 POS metabolites were altered in F-treated 11 weeks rat serum. Four significantly different metabolites, nicotinamide, adenosine, 1-Oleoyl-sn-glycero-3-phosphocholine, and 1-Stearoyl-sn-glycerol 3-phosphocholine were shared by two models. Urea, N2-Acetyl-l-ornithine, and betaine were

A national cross-sectional study on effects of fluoride-safe water supply on the prevalence of fluorosis in China
OBJECTIVE: To assess the effects of provided fluoride-safe drinking-water for the prevention and control of endemic fluorosis in China. DESIGN: A national cross-sectional study in China. SETTING: In 1985, randomly selected villages in 27 provinces (or cities and municipalities) in 5 geographic areas all over China. PARTICIPANTS: Involved 81 786 children aged from

Effects of water improvement and defluoridation on fluorosis-endemic areas in China: A meta-analysis.
Highlights The first analysis of the effect of improving water quality and reducing fluoride in China over 40 years. Analysis of the effect of water improvement and fluoride reduction in different provinces of China. We analyzed the effect of water improvement on dental fluorosis, skeletal fluorosis, and fluoride content

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.

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.

Tea Intake Is a Risk Factor for Skeletal Fluorosis
A number of recent studies have found that heavy tea drinkers can develop skeletal fluorosis - a bone disease caused by excessive intake of fluoride.

Mayo Clinic: Fluoridation & Bone Disease in Renal Patients
The available evidence suggests that some patients wtih long-term renal failure are being affected by drinking water with as little as 2 ppm fluoride. The finding of adverse effects in patients drinking water with 2 ppm of fluoride suggests that a few similar cases may be found in patients imbibing 1 ppm, especially if large volumes are consumed, or in heavy tea drinkers. The finding of adverse effects in patients drinking water with 2 ppm of fluoride suggests that a few similar cases may be found in patients imbibing 1 ppm, especially if large volumes are consumed, or in heavy tea drinkers and if fluoride is indeed the cause. It would seem prudent, therefore, to monitor the fluoride intake of patients with renal failure living in high fluoride areas.
