[Prevalence of enamel defects and the relationship to dental caries in deciduous and permanent dentition in Indaiatuba, São Paulo, Brazil].
The aim of this study was to determine the prevalence of hypoplasia, demarcated opacity and dental fluorosis among schoolchildren with deciduous and permanent dentition. The association between enamel defects and dental caries was also verified. The sample consisted of 624 schoolchildren aged 5 and 309 aged 12. The dmft and

Drinking water fluoride levels, dental fluorosis, and caries experience in Brazil
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.

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

Systematic review of water fluoridation.
Objective: To review the safety and efficacy of fluoridation of drinking water. Design: Search of 25 electronic databases and world wide web. Relevant journals hand searched; further information requested from authors. Inclusion criteria were a predefined hierarchy of evidence and objectives. Study validity was assessed with checklists. Two reviewers independently screened

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

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: The "Cosmetic" Factor
Any condition that can cause children to be embarrassed about their physical appearance can have significant consequences on their self-esteem and confidence. Researchers have repeatedly found that "physical appearance [is] the best predictor of self-esteem" in adolescents, (Harter 2000) and that facial attractiveness, particularly the appearance of one's teeth, is a

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
-
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
