Abstract
Painful, crippling deformities in Tanzanian children from an area of endemic fluorosis are reported. Excessive fluoride ingestion in pregnant women may possibly poison and alter enzyme and hormonal systems in the fetus causing disturbances to osteoid formation and mineralization. Knock-knees, bowlegs, and saber shins develop when walking begins. Combinations of osteomalacia, osteoporosis, and osteosclerosis result in a spectrum of bone changes from an early age. Male hormones, and dietary and genetic deficiencies may aggravate individual response of actively growing bones. Some radiographic changes suggestive of rickets, hyperparathyroidism and thalassemia were observed.

The spectrum of radiographic bone changes in children with fluorosis
Painful, crippling deformities in Tanzanian children from an area of endemic fluorosis are reported. Excessive fluoride ingestion in pregnant women may possibly poison and alter enzyme and hormonal systems in the fetus causing disturbances to osteoid formation and mineralization. Knock-knees, bowlegs, and saber shins develop when walking begins. Combinations of osteomalacia, osteoporosis,

Severe bone deformities in young children from vitamin D deficiency and fluorosis in Bihar-India
A case-control study was undertaken to understand the etiopathology of the bone deformities among young children in a fluoride-affected village of the Bihar State. Two villages were selected: one village with high fluoride in drinking water (7.9 +/- 4.15 ppm), and the other village with normal levels of fluoride (0.6

Vitamin D deficiency, rickets, and fluorosis in India
Data on the vitamin D status of the populations in a tropical country like India have seldom been documented. Vitamin D deficiency is presumed to be rare. Population studied by the author and others in the country has proved otherwise. Studies were carried out to document the dietary habits, serum

Endemic chronic fluoride toxicity and dietary calcium deficiency interaction syndromes of metabolic bone disease and deformities in India: year 2000
Epidemiological studies during 1963-1997 were conducted in 45,725 children exposed to high intake of endemic fluoride in the drinking water since their birth. Children with adequate (dietary calcium > 800 mg/d) and inadequate (dietary calcium < 300 mg/d) calcium nutrition and with comparable intakes of fluoride (mean 9.5 +/- 1.9

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.

Fluoride & Osteomalacia
One of fluoride's most well-defined effects on bone tissue is it's ability to increase the osteoid content of bone. Osteoid is unmineralized bone tissue. When bones have too much of it, they become soft and prone to fracture -- a condition known as osteomalacia. As shown below, fluoride has repeatedly been

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.

Variability in Radiographic Appearance of Skeletal Fluorosis
Osteosclerosis (dense bone) is the bone change typically associated with skeletal fluorosis, particularly in the axial skeleton (spine, pelvis, and ribs). Research shows, however, that skeletal fluorosis produces a spectrum of bone changes, including osteomalacia, osteoporosis, exostoses, changes resulting from secondary hyperparathyroidism, and combinations thereof. Although the reason for this radiographic variability is not yet fully understood, it is believed to relate to the dose of fluoride consumed, the individual's nutritional status, exposure to aluminum, genetic susceptibility, presence of kidney disease, and area of the skeleton examined.

Similarities between Skeletal Fluorosis and Renal Osteodystrophy
It is quite possible, and indeed likely, that some kidney patients diagnosed with renal osteodystrophy are either suffering from skeletal fluorosis or their condition is being complicated/exacerbated by fluoride exposure.

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.
