Abstract
OBJECTIVE: The purpose of this study was to determine the prevalence and severity of dental fluorosis in Mexican adolescents.
MATERIALS AND METHODS: A cross-sectional epidemiological study was carried out in 1,024 adolescents 12 and 15-years-old residing in three naturally fluoridated locales at high altitudes above sea level (> 2,000 m or > 6,560 ft) in Tula de Allende, Hidalgo, Mexico. Participants had lived in those communities from birth to their sixth birthday. Both the Modified Dean Index and the Community Fluorosis Index were calculated.
RESULTS: The overall fluorosis prevalence was 83.8 percent. Fluorosis prevalence in El Llano (3.07 ppmF), San Marcos (1.38 ppmF), and Tula Centro (1.42 ppmF) was 94.7, 89.8, and 81.9 percent, respectively. Overall, the Community Fluorosis Index was 1.85. We observed a high prevalence of dental fluorosis–mostly very mild (35.9 percent), but also uncommonly severe (20.6 percent).
CONCLUSIONS: At least 8 out of 10 adolescents had some level of fluorosis, and such prevalence is considered to be a dental public health problem. A relationship between fluoride concentration in water in each community and fluorosis was observed. The high fluorosis prevalence and severity might possibly be associated with the high altitude of the communities.

The impact of developmental defects of enamel on young people in the UK
OBJECTIVES: To explore the impact of developmental defects of enamel (DDE) on young people, through their experiences of the condition and it's meaning to their everyday lives. METHODS: The theoretical framework chosen to guide the study was symbolic interactionism. Qualitative interviews with a purposive sample of people aged 10-15 years

LS8 cell apoptosis induced by NaF through p-ERK and p-JNK - a mechanism study of dental fluorosis
OBJECTIVE: To investigate the possible biological mechanism of dental fluorosis at a molecular level. MATERIAL AND METHODS: Cultured LS8 were incubated with serum-free medium containing selected concentrations of NaF (0???2?mM) for either 24 or 48?h. Subcellular microanatomy was characterized using TEM; meanwhile, selected biomolecules were analysed using various biochemistry techniques. Transient

A comparison of dental fluorosis in adult populations with and without lifetime exposure to water fluoridation.
OBJECTIVES: There is a lack of evidence on the proportion and severity of fluorosis in adult populations exposed and not exposed to fluoridated water over their lifetimes. The aim of this study was to compare the proportion and severity of fluorosis in adults with lifetime exposure to water fluoridation with

Parents' satisfaction with children's tooth color: fluorosis as a contributing factor
The authors surveyed parents of 708 patients in a pediatric dental practice about their satisfaction with the color of their children's teeth and factors associated with their level of satisfaction. Overall, 43 percent of parents were dissatisfied with their children's tooth color, and 78 percent of children had a Tooth

Chronic endemic fluorosis (with bone affections) in the Punjab.
First Page of Study Since the investigation of Black an,d McKay in 1916 into the problem of mottled enamel, and the definite association of this anomaly with the fluorine content of drinking waters by Churchill (1931, 1932), the matter of fluorine intoxication has been studied in detail by different workers in

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 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

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.

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: 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
