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.

Fluoride and Oral Health.
In 1993, the World Health Organization convened an Expert Committee to provide authoritative information on the role of fluorides in the promotion of oral health throughout the world (WHO TRS 846, 1994). This present publication is a revision of the original 1994 document, again using the expertise of researchers from

Use of Toothpaste and Toothbrushing Patterns Among Children and Adolescents - United States, 2013-2016.
Fluoride use is one of the main factors responsible for the decline in prevalence and severity of dental caries and cavities (tooth decay) in the United States (1). Brushing children's teeth is recommended when the first tooth erupts, as early as 6 months, and the first dental visit should occur

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

Evaluation of dental fluorosis in relation to DMFT rates in a fluorotic rural area of Turkey
The purpose of this study was to determine the fluoride concentration of drinking water and any correlations between the severity, and discoloration level of dental fluorosis and decayed/missing/filled permanent teeth (DMFT) values in the rural fluorotic village of Deregümü, Isparta, Turkey. Intraoral examination of 293 individuals (150 women, 143 men)

Fluorosis and dental caries in Mexican schoolchildren residing in areas with different water fluoride concentrations and receiving fluoridated salt
OBJECTIVE: To explore the association between fluoride in drinking water and the prevalence and severity of fluorosis and dental caries in children living in communities receiving fluoridated salt. MATERIAL AND METHODS: Participants were schoolchildren (n = 457) living in two rural areas of the State of Morelos, Mexico, where the water

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 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

Mechanisms by Which Fluoride Causes Dental Fluorosis Remain Unknown
When it comes to how fluoride impacts human health, no tissue in the body has been studied more than the teeth. Yet, despite over 50 years of research, the mechanism by which fluoride causes dental fluorosis (a hypo-mineralization of the enamel that results in significant staining of the teeth) is not

Diagnostic Criteria for Dental Fluorosis: The TSIF ("Total Surface Index of Fluorosis")
The traditional criteria (the "Dean Index") for diagnosing dental fluorosis was developed in the first half of the 20th century by H. Trendley Dean. While the Dean Index is still widely used in surveys of fluorosis -- including the CDC's national surveys of fluorosis in the United States -- dental

"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.
