Abstract
It is observational, analytical and cross-sectional aimed to evaluate the association between severity and prevalence of fluorosis and dental caries in rural communities with endemic dental fluorosis in the north state of Minas Gerais, Brazil, with fluoride concentrations in water up to 4.8 mg/L. Data were collected by one examiner (intra-examiner kappa, 0.96 to 0,95 for caries and fluorosis) after toothbrushing. The study included 511 individuals aged 7 – 22 years, categorized according to age: 7 – 9 years (n = 227), 10 to 12 years (n = 153), 13 to 15 years (n = 92), 16 to 22 years (n = 39). For the diagnosis of dental caries used the criteria of the World Health Organization to measure indices DMFT. For fluorosis used the index Thylstrup and Fejerskov (TF), dichotomized according to prevalence (TF = 0 and TF > 0) and severity (TF < 4 and TF > 5). In the two younger groups, the DMFT and its decay component were higher in the group with more severe fluorosis (p < 0.001). This association was not found among adolescents and adults (p > 0.05). The association was found between the conditions more severe fluorosis and caries in individuals under 12 years.

The association between enamel fluorosis and dental caries in U.S. schoolchildren.
BACKGROUND: The authors assessed the association between enamel fluorosis and dental caries to determine if there is any beneficial effect of enamel fluorosis in U.S. schoolchildren. METHODS: The authors used data from a National Institute of Dental Research survey of the oral health of U.S. children conducted in 1986 and 1987

Relationship of caries and fluorosis in adolescents from high- and low-fluoride areas in Iran
OBJECTIVE: The main aim of the study was to investigate the association between water fluoride concentration and caries as well as fluorosis occurrence in adolescents in Iran. As a secondary aim we studied the relationship between caries and fluorosis occurrence. BASIC RESEARCH DESIGN: We examined 12-16 year-olds (n = 373) in

Prevalence and severity of dental caries in adolescents aged 12 and 15 living in communities with various fluoride concentrations
OBJECTIVES: To determine the experience, prevalence, and severity of dental caries in adolescents naturally exposed to various fluoride concentrations. METHODS: A cross-sectional census was conducted on 1,538 adolescents aged 12 and 15 years living at high altitude above sea level (> 2,000 m or > 6,560 ft) in above-optimal fluoridated communities

Dental caries and developmental defects of enamel in relation to fluoride levels in drinking water in an arid area of Sri Lanka
The study was conducted to assess caries and developmental defects of enamel in relation to fluoride levels in drinking water and the association between caries experience and the severity of diffuse opacities in children living in Uda Walawe, an area with varying concentrations of fluoride in drinking water in Sri Lanka. A total of

Dental fluorosis and caries prevalence in the fluorosis endemic area of Asembagus, Indonesia
OBJECTIVES: The aim of this study was to determine the prevalence and severity of dental fluorosis and caries in a fluorosis endemic area, with fluoride content in drinking water ranging from 0.51 to 3.15 ppm. MATERIALS AND METHODS: Children (n = 474), aged 6-12 years, were randomly selected from one primary

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 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

"Mild" Dental Fluorosis: Perceptions & Psychological Impact
The vast majority of research has found that patients, parents, and the general public alike view mild fluorosis (TF score 3) as a significant blemish of the teeth, one that is likely to embarrass the affected child to a degree that cosmetic treatment would be warranted.

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.

In 1984, a panel from the National Institute of Mental Health (NIMH) warned
