Abstract
Combined treatment with sodium fluoride, calcium and vitamin D is claimed to be beneficial in some patients with osteoporosis. Fluoride alone leads to accumulation of unmineralised bone, producing the histological picture of osteomalacia. The addition of calcium or vitamin D, or both, is believed to prevent this complication. We report a case where osteomalacia developed during sodium fluoride treatment despite large doses of vitamin D and associated high plasma 25-hydroxyvitamin D (25-OHD) concentrations.

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

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

Human vertebral bone: relation of strength, porosity, and mineralization to fluoride content
Radiographically normal vertebral bone cylinders from 80 male subjects were tested mechanicallly by static compression and analyzed for porosity, fluoride and ash content. As a group, they had low fluoride content, suggesting little prior intake, consonent with this geographic area. Nevertheless, increasing levels of fluoride were associated with bulkier bone,

Effects of fluoride on bone in chronic renal failure
Fluoride is concentrated in the bones of patients with chronic renal failure when fluoridated water is used during hemodialysis. Excessive osteoid is produced that is not normally mineralized and severe osteomalacia occurs. Electron microscopical examination of iliac crest bone biopsy specimens from four patients suggests that fluoride induces the synthesis

Addition of monofluorophosphate to estrogen therapy in postmenopausal osteoporosis: a randomized controlled trial
INTRODUCTION: Treatment of osteoporosis with high-dose fluoride alone does not reduce fracture risk. We hypothesized that the antifracture efficacy of fluoride could be optimized by its use in low doses combined with an antiresorptive agent. EXPERIMENTAL SUBJECTS: Subjects included 80 women with postmenopausal osteoporosis who had been taking estrogen for at least 1

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

Fluoride Exposure Increases Metabolic Requirement for Calcium & Vitamin D
It is well known that individuals with nutrient deficiencies are more susceptible to fluoride toxicity, including fluoride's bone effects. As discussed in the following studies, fluoride increases the skeleton's need for calcium (and vitamin D) by increasing the amount of unmineralized tissue (osteoid) in the bone. When insufficient calcium and

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.

Fluoride & Osteoarthritis
While the osteoarthritic effects that occurred from fluoride exposure were once considered to be limited to those with skeletal fluorosis, recent research shows that fluoride can cause osteoarthritis in the absence of traditionally defined fluorosis. Conventional methods used for detecting skeletal fluorosis, therefore, will fail to detect the full range of people suffering from fluoride-induced osteoarthritis.

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.
