Abstract
During an 8-year period, 163 consecutive patients with spinal crush fracture osteoporosis started a 5-year treatment with a combination of sodium fluoride (60 mg/day), calcium phosphate (45 mmol/day) and vitamin D2 (18,000 IU/day), and were followed in the outpatient clinic every 3 months. Fourty-three patients completed the 5-year treatment. Mean observation time was 2.8 years, totalling 460 patient-years. Fifty-one percent of the patients experienced joint-related (37%) or gastrointestinal (25%) side effects at one time or another. All side effects subsided after a median 6-week withdrawal of fluoride. Six percent of the patients withdrew from treatment due to side effects. Mean serum calcium values slightly decreased during treatment and no hypercalcemic episodes were seen. Urinary excretion of calcium did not change during treatment. No changes in renal, bone marrow or thyroid functions could be detected. The liver function might be slightly affected as indicated by minute increases in serum bilirubin and decreases in serum coagulation factors and albumin, but no other changes in liver function were observed.

Fluoride in Drinking Water: A Scientific Review of EPA’s Standards.
Excerpts: Summary Under the Safe Drinking Water Act, the U.S. Environmental Protection Agency (EPA) is required to establish exposure standards for contaminants in public drinking-water systems that might cause any adverse effects on human health. These standards include the maximum contaminant level goal (MCLG), the maximum contaminant level (MCL), and the secondary

Early diagnosis and classification of professional fluorosis
On the basis of evaluating the clinical course and supplementary method of examination carried out in 132 patients suffering of professional fluorosis and in 200 workers in the premorbid state the author proposes criteria of early diagnosis. Considering Zislin's classification of professional fluorosis, literature data and own findings the author

Toxicology and Carcinogenesis Studies of Sodium Fluoride in F344/N Rats and B6C3F1 Mice (Drinking Water Studies)
CASRN: 7681-49-4 Chemical Formula: NaF Molecular Weight: 41.99 Report Date: December 1990 Sodium fluoride is a white, crystalline, water-soluble powder used in municipal water fluoridation systems, in various dental products, and in a variety of industrial applications. Toxicology and carcinogenesis studies were conducted with F344/N rats and B6C3F1 mice of each sex by incorporating

Clinical features of early stages of occupational fluorosis under the combined and joint effect of production factors
Over 1000 workers of hydrofluoric and cryolite enterprises and electrolysis shops of aluminium enterprises were examined. Subjects exposed to soluble hydrofluorides presented in the early stage of chronic intoxication with a variety of syndromes, that was characteristic of intoxication with poisons of general toxic action with involvement of hepatobiliary, digestive,

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

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.

Gastrointestinal Problems Among Individuals with Skeletal Fluorosis
Humans suffering from skeletal fluorosis are known to suffer from an increased occurrence of gastrointestinal disorders. When fluoride intake is reduced, these gastrointestinal problems are among the first symptoms to disappear. The following are some of the studies that have examined this issue: "It is clear from the observations presented in this article

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 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
