Abstract
Clinical trials of dietary fluoride supplements began in the 1940s in an effort to bring the benefits of fluoride to those who did not receive it through their drinking water. Following the early success of these trials, the Council on Dental Therapeutics of the American Dental Association (ADA) published its first recommendations for fluoride supplementation in 1958. The American Academy of Pediatrics (AAP) followed with its own recommendations in 1972. During the 1970s a variety of alternative schedules appeared in the literature, most in reaction to the findings of unexpectedly high levels of enamel fluorosis in children being supplemented with the AAP schedule. In 1979 the ADA and AAP agreed on essentially identical schedules. During the 1980s, however, the prevalence of enamel fluorosis continued to increase, and fluoride supplements were found in some studies to be a risk factor for fluorosis. This finding prompted another round of dosage schedule recommendations in the early 1990s. This paper presents a history of fluoride dosage recommendations and reviews the recent proposals for reducing supplement dosage.

Fractional urinary fluoride excretion and nail fluoride concentrations in normal, wasted and stunted 4-5 year-old children in Nepal.
Highlights It is suggested that undernourished children may be more likely develop dental fluorosis. Fluoride intake and excretion were measured in normal, wasted and stunted children. Proportion of ingested fluoride excreted via urine was not related to nutritional status. Nutritional status affected fingernail- but not toenail- fluoride concentration. Abstract Introduction It has

Unsuitability of World Health Organisation guidelines for fluoride concentrations in drinking water in Senega
A survey was done of the prevalence of dental fluorosis among children aged 7-16 years and the occurrence of skeletal fluorosis among adults aged 40-60 years living in regions in Senegal where fluoride concentrations in the drinking water ranged from less than 0.1 to 7.4 mg/l. In the area where the fluoride concentration

Biomarkers for the Assessment of Fluoride Exposure in Children.
Due to practical difficulties in quantifying fluoride exposure, the ability of various biomarkers to predict exposure has been investigated previously. However, the results are inadequate for validation of their application and usefulness. This study aimed to investigate the association between contemporary/recent biomarkers of fluoride exposure and total daily fluoride intake

Dental Fluorosis over Time: A comparison of National Health and Nutrition Examination Survey data from 2001-2002 and 2011-2012.
Purpose: Excessive fluoride ingestion has been associated with dental fluorosis. The purpose of this study was to determine if there was a difference in dental fluorosis prevalence comparing National Health and Nutrition Examination Survey (NHANES) trend data for adolescents, aged 16 and 17 years, when compared to data collected in

Fluoride toxicosis in immature herbivorous domestic animals living in low fluoride water endemic areas of Rajasthan, India: An observational survey
Susceptibility to fluoride toxicosis in the form of osteo-dental fluorosis was observed among 435 immature herbivorous domestic animals living in areas with less than 1.5 ppm fluoride in the drinking water. These animals included 78 buffaloes (Bubalus bubalis), 89 cattle (Bos taurus), 30 donkeys (Equus asinus), 21 horses (Equus caballus),

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

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.

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.

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
