Abstract
Despite improvement, dental caries is still the main public oral health problem worldwide and the major cause of pain, tooth loss and chewing difficulties in children and adolescents; and it impacts negatively on oral health-related quality of life. A cross-sectional study of a multistage representative sample of 8-12-year-old Brazilian school children was carried out in order to investigate the association between enamel defects and dental caries. Children’s mothers completed a questionnaire about socio-demographic and behavioural characteristics at home. Firth’s bias reduced logistic regression models were undertaken to assess the association between the main exposure (enamel defects) and caries experience. The prevalence of any enamel defect was 64.0%; the prevalence of diffuse opacities, demarcated opacities and enamel hypoplasia was 35.0%, 29.5% and 3.7%, respectively. The prevalence of dental caries was 32.4%, with mean DMFT of 0.6 (SD, 1.2). Dental caries experience was more common among children who had enamel hypoplasia in their posterior teeth (OR=2.79; 95% CI: 1.05, 6.51) than among those with none. In anterior teeth, there was no association. Enamel hypoplasia appears to be an important risk factor for dental caries.

ENAM Gene Variation in Students Exposed to Different Fluoride Concentrations.
The ENAM gene is important in the formation of tooth enamel; an alteration can affect the lengthening of the crystals, and the thickness in enamel. The objective was to determine the presence of the single nucleotide variant (SNV) rs12640848 of the ENAM gene in students exposed to different concentrations of

The relationship between dental caries and dental fluorosis in areas with moderate- and high-fluoride drinking water in Ethiopia
OBJECTIVE: The aim of the study is to assess the relationship between caries and dental fluorosis in Ethiopian children living in Rift Valley areas known for endemic fluorosis. METHOD: A total of 306 children (12-15 years old), selected from areas with moderate (0.3-2.2 mg/l), or high (10-14 mg/l)fluoride concentration in the

Evaluation of Eruption Pattern and Caries Occurrence among Children Affected with Fluorosis.
AIM: The aim of this study was to evaluate eruption pattern and occurrence of caries in children affected with fluorosis. MATERIALS AND METHODS: One hundred and fifty subjects (75 each with/without fluorosis) with age group of 7-8 years were selected. Dental fluorosis assessed on the buccal surfaces of the permanent incisors

Some Epidemiological Aspects of Chronic Endemic Dental Fluorosis.
Excerpt THE endemic hypoplasia of the permanent teeth known in this country as mottled enamel was first reported by Eager in 1901. The first investigation in the United States was the extensive one of Black,2 and McKay,3 published in 1916. At present in this country alone there are more than 200

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

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

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
