Abstract
26 women were treated for osteoporosis with 40 mg of sodium fluoride twice a day (equivalent 36 mg of fluorine) for a longer period. Mostly by reason of incompatibility, a reduction to half of the dose was necessary in six of these patients. The control of plasma fluoride concentration indicated that only 10 patients took their medicine regularly. Before treatment as well as three and six months after beginning of treatment the patients were examined. In these examinations bone density was measured across the middle phalanx of the middle finger with a I-125-profile scanner. Size and function of the thyroid gland were evaluated by clinical aspects and with in vivo- and in vitro-methods for thyroid diagnostic. The program includes also a check up with a 12 canal-serum-autoanalyzer. In 10 patients with warranted regular intake of the drug the increase of bone density was significant after three months already. In all 26 patients a considerable increase of the alkaline phosphatase after three months was evident. Under the influence of sodium fluoride no change was seen in function and size of thyroid gland. This result verifies the efficiency of sodium fluoride in osteoporosis-therapy without any measurable influence on thyroid function.

Studies of relationships between the polymorphism of COMT gene and plasma proteomic profiling and children’s intelligence in high fluoride areas
Part I – Effect of high F drinking water on children’s IQ Objective: To investigate the relationships among the children’s serum F, urine F, thyroid hormone levels and children’s IQ in the high fluoride areas. Methods: We collected the samples of the drinking water, urine and blood and measured the F concentrations,

Excess fluoride ingestion and thyroid hormone derangements in children living in Delhi, India
SUMMARY: Ninety children with dental fluorosis, aged 7–18, living in fluoride endemic, non-iodine deficient areas of the National Capital Territory of Delhi, India, where iodized salt has been promoted for over a decade, were investigated, along with 21 children in two control groups without dental fluorosis living in non- endemic

Elevated serum fluoride concentrations in women are not related to fractures and bone mineral density
Epidemiologic studies of the relations between drinking-water fluoride levels and bone mineral density (BMD) and fracture are characterized by disparate conclusions and an absence of information about individual circulating fluoride levels. This study relates serum fluoride concentrations, which reflect individual fluoride exposures, to BMD and bone fractures. Data are from

Effects of fluoride on bone metabolism in patients with hemodialysis
The maior pathway of fluoride elimination from the human body is the kidney. The discharge of fluoride into urine depends on the clearance of the kidney. Fluoride in serum of hemodialysis patients is higher than that of healthy subjects. Fluoride is not reduced sufficiently with hemodialysis. Those patients are in

Fluoride & Goiter
Goitre (aka goiter) is an enlargement of the thyroid gland that in some cases can produce visible swelling in the neck. The main cause of goitre is iodine deficiency. Goitre can also be caused by other things, including hypothyroidism and substances that cause goitre (goitrogens). Since as far back as the

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.

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

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.

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.
