  • Fluoride exposure and indicators of thyroid functioning in the Canadian population: implications for community water fluoridation.

    BACKGROUND: There are concerns that altered thyroid functioning could be the result of ingesting too much fluoride. Community water fluoridation (CWF) is an important source of fluoride exposure. Our objectives were to examine the association between fluoride exposure and (1) diagnosis of a thyroid condition and (2) indicators of thyroid

  • Absence of effect of fluoride upon the incidence of thyroid enlargements in Wiltshire schoolgirls.

    From the survey by Kilpatrick et al. (p. 654, col. 1, Vol. 32) it was possible to classify 696 schoolgirls in 4 groups according to intake of I, which was higher in those taking school lunches than in those not doing so because iodised salt was used for cooking, and

  • The synergistic action of thyroid on fluoride toxicity

    Control rats on the basic diets employed developed normal or nearly normal incisor teeth. Rats on the same basic diets to which dried thyroid had been added developed incisor teeth that were markedly bleached due to a potentiation of the toxic action of the fluorine in the basic diet. Subcutaneous

  • Are fluoride levels in drinking water associated with hypothyroidism prevalence in England? A large observational study of GP practice data and fluoride levels in drinking water

    Background: While previous research has suggested that there is an association between fluoride ingestion and the incidence of hypothyroidism, few population level studies have been undertaken. In England, approximately 10% of the population live in areas with community fluoridation schemes and hypothyroidism prevalence can be assessed from general practice data.

  • The Relationship Between Fluoride Exposure & Goitre in South Africa

    As a general rule simple goitre, irrespective of the cause, can be very, or fairly, satisfactorily combated by an adequate increase in man's daily iodine intake, except when the enlargement of the gland is due to the ingestion of excessive amounts of fluorine. The only correct solution to fluorine-induced endemic goitre is the removal of this element from the drinking water.

  • Fluorine in the Aetiology of Endemic Goitre

    The distribution of endemic goitre in the Punjab and in England is related to the geological distribution of fluorine and to the distribution of human dental fluorosis (mottled enamel). Inquiry showed the presence of dental fluorosis among school-children in two areas of Somerset where two previous observers had recorded a high incidence of goitre, and the absence of dental fluorosis in an adjoining area selected as control where endemic goitre was absent.

  • Mikhailets (1996): Functional state of thyroid under extended exposure to fluorides

    Abnormalities in the thyroid function characterized by a decreased iodine absorption function of the thyroid, a low level T3 syndrome, and a slight increase of the TSH level are observed in cases of chronic fluorine intoxication in the industrial workers.

  • NRC (2006): Fluoride's Impact on the Thyroid Gland

    Several lines of information indicate an effect of fluoride exposure on thyroid function. It is difficult to predict exactly what effects on thyroid function are likely at what concentration of fluoride exposure and under what circumstances.

  • Fluoride Exposure Aggravates the Impact of Iodine Deficiency

    A consistent body of animal and human research shows that fluoride exposure worsens the impact of an iodine deficiency. Iodine is the basic building block of the T3 and T4 hormones and thus an adequate iodine intake is essential for the proper functioning of the thyroid gland. When iodine intake is inadequate during infancy and
