  • The oral microbiome: Role of key organisms and complex networks in oral health and disease.

    7.2. Toothpaste The effects of toothpaste on the oral microbiota have been investigated more thoroughly than the effects of toothbrushes. In the same study as previously described,33 the researchers also compared the oral and toothbrush microbiotas of participants who used either traditional Chinese medicine toothpaste or antibacterial toothpaste. While both types of toothpaste effectively reduced […]

  • Dose dependence of prenatal fluoride exposure associations with cognitive performance at school age in three prospective studies.

    Fluoride exposure from the Odense Child Cohort (OCC) While the addition of fluoride to drinking water is not legal in Denmark, elevated fluoride concentrations up to 1.5 mg/l naturally occur in groundwater in parts of the country,13 and some types of tea, especially black tea, constitute an additional source of exposure.14 In Odense municipality, the […]

  • Irish get teeth into man-made fluoride

    IRISH activists and MEPs have called upon Environment Commissioner Margot Wallstrom to remove wording from an EU drinking-water directive that allows a type of fluoride classified as an ‘industrial waste chemical’ to enter local water supplies in Ireland and the UK. Hexafluorosilic acid has been added to certain regional water supplies in both member states […]

  • Letter from MEP: Say no to fluoride

    The call from Britain’s top dental body for Holyrood to add fluoride to Scotland’s water must be strongly resisted. The British Dental Association (BDA) claims adding this chemical to our water would help to fight the appalling tooth decay still prevalent in some parts of Scotland. However, even by its own admission, the dental health […]

  • Hydrogen fluoride is ubiquitous throughout the Milky Way

    ESA’s Herschel infrared space observatory has found that hydrogen fluoride molecules are everywhere in interstellar gas clouds. They betray hidden reservoirs of gas, and may ultimately become a key tracer of star-forming gas clouds in distant galaxies. Hydrogen is the most abundant element in the Universe, making up three-quarters of the normal matter. But at […]

  • Guernsey: Anglers at St Saviour’s reservoir warned over eating fish

    Anglers in Guernsey have been asked to limit the number of fish they eat from St Saviour’s reservoir, after a chemical was detected in the water. Environmental Health said the chemical was known as PFOS, and was a component of fire-fighting foam. It stressed that while anglers were unlikely to be eating enough fish to […]

  • Toxic ash threatens Iceland animals

    Farmers in southern Iceland have been racing to protect their animals from being poisoned by volcanic dust. The animals are at risk of fluoride poisoning if they inhale or ingest the ash, leading to internal bleeding, long-term bone damage and teeth loss. Sheep, cattle and horses were rushed to shelter after they got lost in […]
