E. BELTRAN, Centers for Disease Control and Prevention, Atlanta, GA, USA, and L. BARKER, U.S. Centers for Disease Control and Prevention, Atlanta, GA, USAObjective: To describe the prevalence of enamel fluorosis among adolescents aged 12 to 15 and 16 to 19 years using data from the three most recent cycles of the National Health and Nutrition Examination Surveys (NHANES) in the U.S: 1999-2000, 2001-2002, and 2003-2004. Methods: NHANES is an ongoing survey of representative samples of the civilian non institutionalized U.S. population. Intraoral examinations were conducted by seven trained dentists using standardized criteria, with no examiner serving in all three cycles. Enamel fluorosis was assessed in all permanent teeth using Dean’s Fluorosis Index (DFI). Data were analyzed in SAS and SUDAAN to account for the complex sample design. Results: Table below presents percentages (standard errors) and prevalence of fluorosis, including very mild or higher severity. Cycle: 1999-2000 2001-2002 2003-2004 1999-2004 Age: 12-15 16-19 12-15 16-19 12-15 16-19 12-15 16-19 Unaffected & questionable 60.63 (4.66) 66.25 (4.32) 65.95 (3.18) 70.57 (3.33) 51.58 (3.78) 55.10 (4.59) 60.12 (2.28) 64.55 (2.40) Very Mild 26.17 (2.99) 21.16 (2.94) 24.82 (2.62) 20.63 (2.32) 34.58 (2.65) 31.96 (3.75) 27.98 (1.61) 24.10 (1.76) Mild 8.67 (1.49) 6.98 (0.84) 6.57 (1.14) 6.47 (1.05) 10.31 (1.57) 9.67 (0.88) 8.34 (0.81) 7.58 (0.53) Moderate & severe 4.53 (1.22) 5.61 (1.44) 2.66 (0.40) 2.33 (0.61) 3.52 (0.85) 3.27 (0.94) 3.56 (0.51) 3.78 (0.64) Prevalence 39.37 (4.66) 33.75 (4.32) 34.05 (3.18) 29.43 (3.33) 48.42 (3.78) 44.90 (4.59) 40.60 (2.23) 36.29 (2.45) Conclusions: Between 1999 and 2004, approximately 41% of adolescents aged 12 to 15 and 36% aged 16 to 19 years had enamel fluorosis. Moderate and severe fluorosis was observed in less than 4% in both age groups. Considering the little historical change in fluoride sources and practices at the age these adolescents were at risk for fluorosis, differences among data cycles suggest inter-examiner variability.

    OBJECTIVES: The objectives of this study were to report on the prevalence of enamel opacities from seven European study sites using a standardized photographic method, and to investigate the importance of variables responsible for enamel fluorosis. METHODS: The sample comprised a randomly selected group of 300 8-year-old children in each

  • Dental fluorosis in the Australian adult population.

    Background: The use of fluoride involves a balance between protection against caries and risk of dental fluorosis. Prevalence and trend of dental fluorosis in the adult population are not frequently reported. Objective: To describe the prevalence of dental fluorosis in the Australian adult population. Method: Data

    About 99% of the Norwegian population are supplied with surface water with very low fluoride levels. Accordingly, they need to use fluoride preparations to prevent dental caries. Groundwater with excess fluoride is a problem mainly in a few areas of South-Eastern Norway, where in some samples of borehole water the

    OBJECTIVES:  To evaluate the role of partial recording protocols (PRPs) in reporting prevalence and severity of dental fluorosis and assess whether prevalence/severity estimates derived from PRPs differ by race/ethnicity. METHODS:  Data from the National Health and Nutrition Examination Survey (NHANES) for the years 1999-2004 were analyzed with Stata® v.11. Prevalence of

  • 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

  • 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.

    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.
