Abstract

PURPOSE: The purpose of this study was to estimate fluoride (F) intake from infant formulas prepared with different brands of bottled water.

METHODS: Fluoride concentrations in 4 samples of infant milk and soy-based formulas, commercially available in the United States, prepared with deionized water and 5 brands of bottled water, were determined after Hexamethyldisioxane (HMDS)-facilitated diffusion, in duplicate, using an F ion-specific electrode. Possible fluoride ingestion per killogram body mass was estimated, based on suggested volumes of formula consumption, for infants 1 and 12 months.

RESULTS: Fluoride concentrations ranged from 0.076 to 0.214 ppm and 0.092 to 1.053 ppm for formulas prepared with deionized and bottled water, respectively. When prepared with deionized water, none of the formulas provided an F intake above the suggested threshold for fluorosis (0.07 mg F/kg/day). However, when prepared with some brands of bottled water containing 0.623 and 0.839 ppm, all of them did provide it.

CONCLUSIONS: Some brands of bottled water usually marketed for infants and used to dilute infant formulas may increase fluoride concentrations beyond reccommended levels believed to lead to fluorosis.

    PURPOSE: The purpose of this study was to measure the fluoride concentration in the most commonly consumed, commercially available infant fruit juices and to determine if a significant difference existed among various juice flavors and brands. METHODS: Ninety samples of different flavors from three infant juice manufacturing companies were analyzed using

  • Dietary fluoride intake from infant and toddler formulas in Poland.

    Risk of enamel fluorosis associated with excessive fluoride intake during infancy and early childhood has been widely reported in literature. Results of several studies indicate that infant formula consumption, especially in the form of powdered concentrate, may appreciably increase children's fluoride exposure in optimally fluoridated communities. The aim of the

    BACKGROUND: This article presents evidence-based clinical recommendations regarding the intake of fluoride from reconstituted infant formula and its potential association with enamel fluorosis. The recommendations were developed by an expert panel convened by the American Dental Association (ADA) Council on Scientific Affairs (CSA). The panel addressed the following question: Is

  • Breastfeeding is protective against dental fluorosis in a nonfluoridated rural area of Ontario, Canada

    To determine the relationship between early infant feeding and dental fluorosis in a non-fluoridated area, 1367 children were examined for fluorosis and given a water sample vial and questionnaire. 752 families responded (55%). Breastfeeding was reported by 69% of respondents, with 53.6% breastfed < 6 months, 35.3% 6-12 months, and

  • Risk of enamel fluorosis associated with fluoride supplementation, infant formula, and fluoride dentifrice use.

    Eight hundred fifty 11- to 14-year-old residents of nonfluoridated communities in Massachusetts and Connecticut, who were born between 1972 and 1975, were investigated in a case-control study of the possible association between enamel fluorosis and exposure to fluoride supplements, infant formula, and/or fluoride dentifrice. The effect of median household income,

  • 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.

  • "Mild" Dental Fluorosis: Perceptions & Psychological Impact

    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.

  • 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

    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

  • 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
