Abstract

The study contains the results of fluoride testing done on 31 fetal specimens. It demonstrates that fluoride can pass through the placenta into the fetus, that bone tissues shows the highest levels of fluoride while brain tissue shows the lowest, and that overall level of fluoride increases with the fluoride burden of the mother and the age of the fetus.

  • The fractional urinary fluoride excretion of adults consuming naturally and artificially fluoridated water and the influence of water hardness: a randomized trial

    AIMS:  To assess whether there was any significant difference in the average fractional urinary fluoride excretion (FUFE) values among adults consuming (NaF) fluoridated Ca-free water (reference water), naturally fluoridated hard water and an artificially (H2SiF6) fluoridated soft water. DESIGN:  Sixty adult females (N=20 for each treatment) participated in this randomized, double-blind

    1) The low incidence of dental caries observed in mongoloid patients led to an investigation of the role of fluorine in this condition. 2) A statistical study of the geographical distribution of mongolism in Wisconsin, Illinois, Idaho, North and South Dakota (U.S.A.) shows a parallelism between the prevalence of this condition

    OBJECTIVE: To observe the impacts on skeletal fluorosis pain, joint motor dysfunction and urine fluoride excretion in the treatment with fire needle therapy, electroacupuncture and calcium carbonate D3. METHODS: The randomized controlled trial was adopted. Ninety-five patients were randomized into a fire needle group (31 cases), an electroacupuncture group (33 cases) and a

    The results of a recent study by Whitford et al. [Caries Res 2002;36:256-265] with subjects whose drinking water was fluoridated led to two major conclusions: (1) Compared to the use of a placebo dentifrice, plaque fluoride concentrations ([F]) throughout much of the day are not significantly increased by the use

    A case-controlled study has compared urinary, blood plasma, and serum fluoride (F) levels of people living in endemic areas of the Thar Desert, Sindh, Pakistan, consuming groundwater with F concentrations as high as 4.00–10.00 mg/L with those consuming groundwater with low F levels of 0.30 mg/L. A total of 121

  • Fluoride's Effect on Fetal Brain

    The human placenta does not prevent the passage of fluoride from a pregnant mother's bloodstream to the fetus. As a result, a fetus can be harmed by fluoride ingested pregnancy. Based on research from China, the fetal brain is one of the organs susceptible to fluoride poisoning. As highlighted by the excerpts
