Effect of fluoride on thyroid gland: Clinical study.
No significant differences in protein-bound iodine levels and thyroid gland abnormalities were found when two population groups, one group of 106 persons who used water that naturally contained fluorides (3.48 ppm) and one control group of 109 persons who used essentially fluoride-free water, were compared. All subjects has been residents

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.

[Thyroid gland pathology in children population exposed to the combination of iodine deficiency and fluoride pollution of environment].
The article presents results of study of the impact of iodine deficiency and technogenic fluoride on the state of the thyroid gland in children. On the example of two districts of the city of Bratsk there were executed dynamic investigations (2002 and 2012), including the estimation of the pollution of

The relationship of fluoride and iodine in drinking water in the occurrence of goiter.
In 4 settlements in Israel girls, 2685 in all and aged 7 to 18 years included 17, 30, 4.7 and 2.6% with goitre. In the corresponding water supplies I was, <2, 4 5 to 65, 8 to 100 and 20 µg and F, <0.1, 0 to 0.3, 0.65 to 0.9

[A preliminary approach to the relationship of both endemic goiter and fluorosis in the valley of Manasi River, Xin-Jiang to environmental geochemistry].
According to the geographical features of the inland basins and the motion law by which a variety of chemical elements move along the rivers and deposit in the bottom of the basins in Xinjiang,the author made a series of investigations to find out the effects of the factors of environmental

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, Water Hardness, and Endemic Goitre
Variations in goitre prevalence were found to correlate closely with the fluoride content (p=0-74; P<0-01) and with the hardness (p=0.77; P<0-01) of the water in each village. The effects of fluoride and water hardness seem to be independent.

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.

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

Fluoride's Impact on Thyroid Hormones
Up through the 1950s, doctors in Europe and South America prescribed fluoride for this purpose in patients with hyperthyroidism. (Merck Index 1968). Fluoride was selected as a thyroid suppressant based on findings dating back to the mid-19th century that fluoride is a goitrogen (a substance that can cause goiter). When used as
