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.

Epidemiological, clinical, and biochemical study of endemic dental and skeletal fluorosis in Punjab
The incidence of dental fluorosis in 46,000 children in the Punjab was assessed and compared with the fluoride content of their water supplies. Ten villages were selected for more detailed studies of skeletal as well as dental fluorosis. Factors other than the fluoride content of the drinking water which were found to influence

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

Dental and early-stage skeletal fluorosis in children induced by fluoride in brick-tea
Fluorosis from brick-tea was discovered during the last decade in western and northern parts of China. Dental fluorosis has a high prevalence among children in these brick-tea endemic areas, but skeletal fluorosis does not normally become apparent until adulthood. In July 2002 we examined 132 primary school children, age 8

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

Effect of fluoride ions on apatite crystal formation in rat hard tissues.
Fluoride is widely believed to be a useful chemical substance for preventing dental caries. However, the mechanism underlying crystal perforation in the tooth enamel and the effect of fluoride on hard tissues are unclear. To clarify the mechanism of the biological action of fluoride in the mineralization process, we examined

Moderate/Severe Dental Fluorosis
In its "moderate" and severe forms, fluoride causes a marked increase in the porosity of the enamel. After eruption into mouth, the porous enamel of moderate to severe fluorosis readily takes up stain, creating permanent brown and black discolorations of the teeth. In addition to extensive staining, teeth with moderate to severe fluorosis are more prone to attrition and wear - leading to pitting, chipping, and decay.

Dental Fluorosis Impacts Dentin in Addition to Enamel
Dental fluorosis is a mineralization defect of tooth enamel marked by increased subsurface porosity. The enamel, however, is not the only component of teeth that is effected. As several studies have demonstrated, dental fluorosis can also impair the mineralization of dentin as well. As noted in one review: "The fact that

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.

"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.

Severe Dental Fluorosis: Perception and Psychological Impact
[caption id="attachment_8879" align="aligncenter" width="550"] Severe fluorosis - Photograph by David Kennedy, DDS[/caption] In its severe forms, dental fluorosis causes highly disfiguring brown and black staining of the teeth, which can cause chronic embarrassment and social anxiety for the impacted child. In 1984, a panel from the National Institute of Mental Health (NIMH) warned
