Abstract
Endemic fluorosis is a systematic disease. We investigated the serum free fluoride, thyroid hormones and TSH concentrations in 37 cases. Significantly lowered serum T4 and T3 and increased TSH were found in patients. Patients’ serum rT3 concentrations were not significantly different from the controls. Significant negative correlations were found between serum free fluoride concentrations and T3 concentrations or T3/T4 ratios. We proposed that fluoride intoxication might decrease the thyroid function and suggested the method of prevention and treatment of this condition.

Effects of protein and calcium supplementation on bone metabolism and thyroid function in protein and calcium deficient rabbits exposed to fluoride
This study was conducted to determine whether feeding a diet containing excess crude protein (CP) or calcium (Ca) for up to 120 days can ameliorate the effects of fluoride (F) intake on bone health and thyroid function observed in rabbits fed a CP- and Ca-deficient diet. Treatment with F increased serum bone Gla

Prevention & control of fluorosis & linked disorders: Developments in the 21st Century - Reaching out to patients in the community & hospital settings for recovery.
The review on fluorosis addresses the genesis of the disease, diagnostic protocols developed, mitigation and recovery through nutritional interventions. It reveals the structural and functional damages caused to skeletal muscle and erythrocytes, leading to clinical manifestations in fluorosis. Hormonal derangements resulting in serious abnormalities in the health of children and

Analysis on TSH and intelligence level of children with dental fluorosis in a high fluoride area.
Fluoride is one of the indispensable elements for the living being. Excess amounts of fluoride, however, may damage the teeth and bones. Fluoride may also injure the body’s soft tissues, resulting in nonskeletal fluorosis. To further investigate the influence of endemic fluorosis on childhood thyroid function and intelligence, we have selected school-aged children inflicted with dental fluorosis

Effects of chronic fluorosis on thyroxine, triiodothyronine, and protein-bound iodine in cows
This study was conducted to evaluate the effects of chronic fluorosis in cows on their blood serum levels of thyroxine (T4), triiodothyronine (T3), and protein-bound iodine (PBI). Data collected from twenty cows with chronic fluorosis in the Tendurek Mountain region (altitude about 2000 m) in East Anatolia, Turkey, were compared

Fluoride-induced thyroid dysfunction in rats: roles of dietary protein and calcium level.
To assess the roles of dietary protein (Pr) and calcium (Ca) level associated with excessive fluoride (F) intake and the impact of dietary Pr, Ca, and F on thyroid function, 144 30-day-old Wistar albino rats were randomly allotted to six groups of 24 (female:male = 1:1). The six groups were

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

Fluoride Aggravates Thyroid Damage Caused by Excess Iodine Intake
Chinese researchers have found that the combination of excess fluoride with excess iodine caused greater reductions in IQ, or greater increases in goitre than either scenario by itself.

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.

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.

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
