Abstract
OBJECTIVES: The main aim of this study was to consider the association between water fluoride levels and caries prevalence in three Brazilian populations.
METHODS: A total of 457 6-12-year-old lifetime residents from three economically deprived groups with 2-3, 0.7, and less than 0.01 ppm F in their water supplies were examined. Dental caries was recorded on permanent upper central incisors and first molars and all primary teeth (dmft).
RESULTS: There was a significant trend (P < 01) for the mean dmft to decrease with increasing levels of fluoride in the drinking water. Caries experience in the six permanent teeth was significantly lower (P < 01) in the area with 0.7 ppm F than in the other two groups For the 2-3 ppm F group significantly more caries was found in subjects with higher TF scores (P < 05).
CONCLUSION: Optimization of fluoride levels in the drinking water remains a valuable dental public health measure in Brazil.

Considerations on optimal fluoride intake using dental fluorosis and dental caries outcomes--a longitudinal study
Objectives: The "optimal" intake of fluoride has been widely accepted for decades as between 0.05 and 0.07 mg fluoride per kilogram of body weight (mg F/kg bw) but is based on limited scientific evidence. The purpose of this paper is to present longitudinal fluoride intake data for children free of dental

The effects of a break in water fluoridation on the development of dental caries and fluorosis.
Durham, NC, fluoridated since 1962, had an 11-month cessation of fluoridation between September, 1990, and August, 1991. The purpose of this study was to assess the effects of this break on the development of caries and fluorosis in children. Study participants were continuously-resident children in Kindergarten through Grade 5 in

Higher fluorosis severity makes enamel less resistant to demineralization
Fluorotic teeth could either be more resistant or more susceptible to the caries process than sound ones due to their higher enamel fluoride concentration and higher porosity (subsurface hypomineralization), respectively; however, there is no consensus on this subject. In this study, a total of 49 human unerupted third molars presenting

Caries and dental fluorosis in a 0.25 and a 2.5 ppm fluoride area in the Sudan
The purpose of this study was to assess the caries prevalence of children living in areas with either 0.25 or 2.5 ppm fluoride in the drinking water, and to relate caries experience to the severity of dental fluorosis. The children, aged 6-16 years (mean 11.3 years), were lifelong residents of their rural

Dental caries and endemic dental fluorosis in rural communities, Minas Gerais, Brazil
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

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.

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

Dental Fluorosis Is a "Hypo-mineralization" of Enamel
Teeth with fluorosis have an increase in porosity in the subsurface enamel ("hypomineralization"). The increased porosity of enamel found in fluorosis is a result of a fluoride-induced impairment in the clearance of proteins (amelogenins) from the developing teeth. Despite over 50 years of research, the exact mechanism by which fluoride impairs amelogin

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.

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
