Abstract
Bone specimens from 42 patients with end-stage renal disease and from 9 patients without renal or bone disease have been analyzed for the content of fluoride, calcium, and phosphorus. Thirty-one patients were treated with chronic hemodialysis for periods ranging up to 56 months by employing dialysate made up with tap water containing 1 ppm fluoride. Fluoride content of cortical hard bone was increased in the great majority of patients with kidney disease. There was no significant difference in bone fluoride content between the patients who were dialyzed and those who were not. However, the content of calcium and phosphorus was lower in the patients treated by hemodialysis. There was no correlation between duration of uremia or number of dialyses and bone fluoride content. In 4 patients, 3 with kidney disease and 1 without, soft bone and soft tissue had much higher fluoride content than cortical bone.

Renal osteodystrophy in patients on long-term hemodialysis with fluoridated water
Serum and bone fluoride concentrations of ten patients maintained on long-term hemodialysis with fluoridated water (1 ppm, i.e., 50uM) were correlated with duration of treatment and the occurrence of clinical, radiological, and histological manifestations of bone disease. Two patients had symptomatic renal osteodystrophy when accepted on the program, whereas six

High fluoride concentrations in the serum and bone of patients with chronic renal failure
The aim was to study the effect of ingested fluoride in patients with chronic renal failure (CRF). Serum fluoride concentrations were measured in 104 subjects, who formed three groups: nondialyzed CRF, dialyzed CRF, and a control group. The iliac bone fluoride was measured in 20 subjects. Serum, urine and water

Association between fluoride, magnesium, aluminum and bone quality in renal osteodystrophy
INTRODUCTION: Trace elements are known to influence bone metabolism; however, their effects may be exacerbated in renal failure because dialysis patients are unable to excrete excess elements properly. Our study correlated bone quality in dialysis patients with levels of bone fluoride, magnesium, and aluminum. A number of studies have linked

Osteomalacia is associated with high bone fluoride content in dialysis patients
Osteomalacia is now rarely observed in hemodialyzed patients since the prevention of aluminum intoxication and vitamin D deficiency. However, this disorder is still present and may be responsible for bone fractures. Fluoride overload is responsible for mineralization defects. We therefore prospectively measured the bone fluoride content in all dialysis osteomalacic

Effects of fluoride on bone metabolism in patients with hemodialysis
The maior pathway of fluoride elimination from the human body is the kidney. The discharge of fluoride into urine depends on the clearance of the kidney. Fluoride in serum of hemodialysis patients is higher than that of healthy subjects. Fluoride is not reduced sufficiently with hemodialysis. Those patients are in

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

Exposure Pathways Linked to Skeletal Fluorosis
Excessive fluoride exposure from any source -- and from all sources combined -- can cause skeletal fluorosis. Some exposure pathways , however, have been specifically identified as placing individuals at risk of skeletal fluorosis. These exposure pathways include: Fluoridated Water for Kidney Patients Excessive Tea Consumption High-Fluoride Well Water Industrial Fluoride Exposure Fluorinated Pharmaceuticals (Voriconazole

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.

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

Skeletal Fluorosis in the U.S.
Although there has been a notable absence of systematic studies on skeletal fluorosis in the U.S., the available evidence indicates that the consumption of artificially fluoridated water is likely to cause skeletal fluorosis and other forms of bone disease in people with kidney disease and other vulnerable populations.
