Abstract
The present study has examined the relationship between waterborne fluoride, dental fluorosis and skeletal maturity in two Danish areas containing less than 0.2 and 2.4 parts/10(6) F- in the drinking water. 12–14-year-old girls, 113 from the non-F- area and 122 from the F- area, born and raised in the areas, were examined. No relationship could be found between skeletal maturity and fluoride content of the drinking water. The association between the severity of dental fluorosis and skeletal maturity in the girls from the F- area was not statistically significant, but the tendency followed the same pattern as observed in tropical high and low fluoride areas.

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

The impact of fluoride in drinking water on oral health and skeletal system of school children
Modern life styles even among people in rural areas have created an increased demand for dental cosmetology. Dental fluorosis due to its cosmetic effect gains more public health importance today. In the scenario of increasing awareness of environmental health hazards, among people, the research into the biology of fluorosis conducted

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

Osteo-dental fluorosis in domestic horses and donkeys in Rajasthan, India.
Chronic fluoride (F) intoxication in the form of osteo-dental fluorosis was observed in 23 domestic equus animals, 9 to 23 years old, including 14 horses (Equus caballus), and 9 donkeys (E. asinus) living in F endemic areas of Dungarpur district, Rajasthan, India. The mean F concentration in the drinking water

Endemic Fluorosis. (An Epidemiológical, Biochemical and Clinical Study in the Bhatinda District of Punjab).
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

"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.

Mechanisms by Which Fluoride Causes Dental Fluorosis Remain Unknown
When it comes to how fluoride impacts human health, no tissue in the body has been studied more than the teeth. Yet, despite over 50 years of research, the mechanism by which fluoride causes dental fluorosis (a hypo-mineralization of the enamel that results in significant staining of the teeth) is not

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.
