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.

A pilot study of esthetic perceptions of dental fluorosis vs. selected other dental conditions
The prevalence of fluorosis has increased over the past fifty years, and with this increase, esthetic concerns pertaining to fluorosis should also be taken into consideration. Canadian, Australian, and British studies have explored perceptions concerning enamel fluorosis, but no studies in this area have been published from the United States.

Dental fluorosis, dental caries, and quality of life factors among schoolchildren in a Colombian fluorotic area
OBJECTIVE: To assess dental fluorosis, dental caries and quality of life factors associated with dental fluorosis among schoolchildren living in a Colombian endemic dental fluorosis area. METHOD: 110 12-year olds were visually examined for dental caries (ICDAS) and dental fluorosis (TF) and a self-administered quality of life and fluorosis questionnaire

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

A pilot study of dental students' esthetic perceptions of computer-generated mild dental fluorosis compared to other conditions
OBJECTIVES: Few studies have considered people's opinions about the esthetics of dental fluorosis. Assessments of fluorosis esthetics can be confounded by differences in a number of clinical factors, including tooth shape, color, contour, and gingival status. This pilot study compared esthetic perceptions of mild fluorosis and other conditions using computer-generated

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

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.

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

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

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 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
