Abstract
This reaction time study assessed the valence and strength of evaluations of people with differing levels of fluorosed teeth. Eighty participants rated photographs of smiling faces with four levels of digitally manipulated fluorosed teeth. Faces were presented on a computer screen for a period of 2000 ms followed by a single word descriptor. Participants quickly indicated whether the descriptor applied to the preceding face using a response key. Descriptors included health, aesthetic, and personal judgments. Logistic and linear regressions revealed that participants were significantly more likely to make negative judgments involving health, aesthetic, and person attributions about faces with high levels of fluorosis, and to make negative judgments more quickly and positive judgments more slowly than those with lower levels of fluorosis. These data are consistent with the view that people use negative, easily accessible, stereotypes of individuals presenting with health problems.

Prevalence of dental fluorosis and treatment needs among 11-14 years old school children in endemic fluoride areas of Haryana, India.
Introduction: Dental fluorosis is a major endemic oral disease characterized by hypo mineralization of enamel caused due to consumption of water containing high concentration of fluoride during developmental stages of teeth. Aim: To assess the prevalence of dental fluorosis among 11-14 years old school children in endemic

Aesthetically objectionable fluorosis in the United Kingdom.
OBJECTIVES: A cross-sectional national survey to explore perceptions of dental fluorosis and to determine the proportion of people regarding fluorosis as aesthetically objectionable at differing levels of defect. METHODS: A survey using a multistage stratified random probability sample of 6,000 UK adult households. Face-to-face interviews were carried out using a structured

The aesthetic management of severe dental fluorosis in the young patient
The prevalence of dental fluorosis appears to be on the increase. Although in its mild form the condition is not considered to be of cosmetic significance, the more severe forms can cause great psychological distress to the affected individual. This article discusses the prevalence and mechanisms of dental fluorosis, and

The influence of various fluoride exposures on the prevalence of esthetic problems resulting from dental fluorosis
OBJECTIVES: This study sought to determine the prevalence of esthetic problems due to dental fluorosis, and determine the relationship of different fluoride exposure histories to the occurrence of these problems. METHODS: In 1993-94 2,715 children in grades 2 and 3 and 3,297 adolescents in grades 8 and 9 were examined

Aesthetic concerns of children and parents in relation to different classifications of the Tooth Surface Index of Fluorosis
Increasing prevalence of dental fluorosis for children both from fluoridated and non-fluoridated communities are now well documented. Along with recent studies purporting possible adverse health effects from fluorides, this proven public health intervention is again being challenged. This study was undertaken to determine the prevalence of dental fluorosis for children

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

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

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.

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 Thylstrup-Fejerskov (TF) Index
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
