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.

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

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 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

Nutritional and metabolic rickets
Nutritional rickets is caused by vitamin D deficiency due to lack of exposure to sunlight. Neonatal rickets occurs only in infants born to mothers with very severe osteomalacia. Calcium deficiency alone does not cause mineralisation defects. It only causes osteoporosis and secondary hyperparathyroidism with raised plasma, 1,25 (OH)2D and osteocalcin.

Effects of dialysate calcium and fluoride on bone disease during regular hemodialysis
A previous study indicated that, in patients maintained by hemodialysis, clinically and roentgenographically apparent bone disease appeared almost exclusively when the dialystate calcium concentration was less than 5.7 mg per 100 ml. In the present study, bone biopsy specimens from the iliac crest were studied at the beginning and end

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,

Fluoride & Rickets
One of fluoride's most well-defined effects on bone tissue is it's ability to increase the osteoid (unmineralized bone) content of bone. When bones have too much osteoid, they become soft and prone to fracture -- a condition known as osteomalacia. When osteomalacia develops during childhood, it is called "rickets." The potential for fluoride

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

Fluoridation, Dialysis & Osteomalacia
In the 1960s and 1970s, doctors discovered that patients receiving kidney dialysis were accumulating very high levels of fluoride in their bones and blood, and that this exposure was associated with severe forms of osteomalacia, a bone-softening disease that leads to weak bones and often excruciating bone pain. Based on

Unheeded Warnings: Government Health Authorities Ignore Fluoride Risk for Kidney Patients
Despite the well known fact that individuals with kidney disease are at much higher risk of fluoride toxicity than the general population, there has yet to be any attempt in the United States, or any other country that practices mass-scale water fluoridation to determine the prevalence of fluoride-related effects (e.g.,
