Abstract
About 99% of the Norwegian population are supplied with surface water with very low fluoride levels. Accordingly, they need to use fluoride preparations to prevent dental caries. Groundwater with excess fluoride is a problem mainly in a few areas of South-Eastern Norway, where in some samples of borehole water the fluoride concentration has even exceeded 10 ppm. A warning is given against the use of high-fluoride water when preparing drinks and foods for children. Infants given dried milk formulas diluted with water are at particular risk of developing fluorosis. The recommended daily meals for a three month-old child contain 900 ml water. At a level of 2 ppm, the fluoride content of this volume will exceed the upper limit of the safe and adequate intake for a child this age by 3-4 times. Water used for this purpose should preferably not contain more than 0.5 ppm fluoride. While only few Norwegians are at risk of being exposed to high-fluoride water this problem affects many persons in other parts of the world. With reference to a joint Kenyan-Norwegian research project, the paper is illustrated by cases of dental fluorosis from a Kenyan village supplied with 9 ppm fluoride water. Dental fluorosis of such severity has never been encountered in Norway.

Characteristics of epidemiology of dental caries in children from regions with high and optimum fluorine content in drinking water.
Objective: Introduction: Prevention of dental diseases in children is the priority item on the modern dentistry agenda. Among the undeniable factors known as contributing into caries incidence, there is fluoride content in the external environment, especially in drinking water, which is the main source of fluoride intake. The aim: This

Dental Fluorosis Trends in US Oral Health Surveys: 1986 to 2012
Introduction: Dental fluorosis has been assessed only 3 times in nationally representative oral health surveys in the United States. The first survey was conducted by the National Institute of Dental Research from 1986 to 1987. Subsequently, the National Health and Nutrition Examination Survey (NHANES) conducted fluorosis assessments from 1999 to 2004

Assessing Fluorosis Incidence in Areas with Low Fluoride Content in the Drinking Water, Fluorotic Enamel Architecture, and Composition Alterations.
There is currently no consensus among researchers on the optimal level of fluoride for human growth and health. As drinking water is not the sole source of fluoride for humans, and fluoride can be found in many food sources, this work aimed to determine the incidence and severity of dental

Spatial distribution of fluoride in drinking water and health risk assessment of children in typical fluorosis areas in north China.
Highlights Fluoride content in drinking water for fluorosis areas in Tianjin was investigated. MWS system has a better effect on reducing water fluoride concentration. Younger children (1–4 years old) are more vulnerable to high fluoride exposure. Special attention should be paid to health education strategies against fluorosis. Abstract China has been suffering

Dental Fluorosis in the U.S. 1950-2004
Before the widespread use of fluoride in dentistry, dental fluorosis was rarely found in western countries. Today, with virtually every toothpaste now containing fluoride, and most U.S. water supplies containing fluoride chemicals, dental fluorosis rates have reached unprecedented levels. In the 1950s, it was estimated that only 10% of children in

Community Fluorosis Index (CFI)
The current Community Fluorosis Index for U.S. adolescents as a whole (from both fluoridated and non-fluoridated areas) is roughly 5 times higher than the CFI health authorities predicted for fluoridated areas when fluoridation first began. It is also higher than the CFI that the NIDR found in fluoridated areas back in the 1980s. It is readily apparent, therefore, that children are ingesting far more fluoride than was the case in the 1950s, and even as recently as the 1980s.

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.
