Abstract
Three cases are reported in which fluoride was administered to individuals with osteoporosis. Bone biopsies taken after 7 to 24 months of therapy show that the effect of fluoride on bone tissue appears to be stimulation of new bone formation. If calcium and vitamin D are not administered with the fluoride, the new bone is largely uncalcified; however, if an increase in calcium absorption is produced, then the new bone tissue appears relatively normal.

Effects of sodium fluoride, vitamin D, and calcium on cortical bone remodeling in osteoporotic patients
The purpose of this histomorphometric study of iliac bone biopsies from 10 postmenopausal osteoporotic patients was to describe the effects of sodium fluoride (combined with calcium and vitamin D) on remodeling in cortical bone after 6 months and after 5 years of treatment. Biopsies had been fixed in absolute methanol,

Effect of combined therapy with sodium fluoride, vitamin D and calcium in osteoporosis
Fluoride administration in both man and animals has been shown to stimulate new bone formation. However, the bone is poorly mineralized, and osteomalacia and secondary hyperparathyroidism frequently occur. In this study we investigated the effect of variable levels of fluoride and calcium intake, accompanied by vitamin D, on osteoporosis in

Effect of fluoride on reactive oxygen species and bone metabolism in postmenopausal women.
A study was made of the effects of fluoride (F) on the antioxidant defense systems of postmenopausal women residing in a fluorotic and a nonfluorotic village in Chitoor district, Andhra Pradesh, India. Twenty-five postmenopausal women (approximately 10 years postmenopause, mean age 57 years) residing in endemic fluorotic Adharam and nonfluorotic

Effect of variations in calcium intake on the skeleton of fluoride-fed kittens
Kittens were fed fluoride (2.5 mg. per kilogram of body weight) for 2 months. In one group of animals the addition of calcium (20 mg. per kilogram) to an otherwise calcium-deficient diet resulted in a depressed serum calcium, abnormally wide osteroid tissue, and increased formation and resorption of bone. In

Histomorphometric analysis of iliac crest bone biopsies in placebo-treated versus fluoride-treated subjects
In a 4-year controlled, prospective trial, histomorphometric analysis was used to compare the tissue-level skeletal effects of fluoride therapy in 43 postmenopausal women (75 mg NaF/day) with those of 35 matching placebo subjects; all subjects received 1500 mg/day elemental calcium supplement. In addition to an initial, baseline biopsy, a second

Nutrient Deficiencies Enhance Fluoride Toxicity
It has been known since the 1930s that poor nutrition enhances the toxicity of fluoride. As discussed below, nutrient deficiencies have been specifically linked to increased susceptibility to fluoride-induced tooth damage (dental fluorosis), bone damage (osteomalacia), neurotoxicity (reduced intelligence), and mutagenicity. The nutrients of primary importance appear to be calcium,

Skeletal Fluorosis: The Misdiagnosis Problem
It is a virtual certainty that there are individuals in the general population unknowingly suffering from some form of skeletal fluorosis as a result of a doctor's failure to consider fluoride as a cause of their symptoms. Proof that this is the case can be found in the following case reports of skeletal fluorosis written by doctors in the U.S. and other western countries. As can be seen, a consistent feature of these reports is that fluorosis patients--even those with crippling skeletal fluorosis--are misdiagnosed for years by multiple teams of doctors who routinely fail to consider fluoride as a possible cause of their disease.

Dental Fluorosis & Enamel Hypoplasia in Children with Kidney Disease
Children with kidney disease are known to have high levels of fluoride in their blood and to be at risk for disfiguring tooth defects. Research suggests that high levels of fluoride in blood, which can cause the tooth defect known as dental fluorosis, can contribute to the defects that occur

Kidney Patients Are at Increased Risk of Fluoride Poisoning
It is well established that individuals with kidney disease are susceptible to suffering bone damage and other ill effects from low levels of fluoride exposure. Kidney patients are at elevated risk because when kidneys are damaged they are unable to efficiently excrete fluoride from the body. As a result, kidney patients

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
