Abstract
Patients with osteoporosis were treated for two years with sodium fluoride. Fifteen received sodium fluoride in capsules, 56 in enteric coated slow release tablets (Ossin) and 20 in enteric coated tablets (Procal). Seven women treated with Procal were also treated with oestrogens. All patients had a calcium intake between 1000 and 2000 mg/day, used dihydrotachysterol for vitamin suppletion and were advised to exercise. Non-responders were arbitrarily defined as those who had an increase in serum alkaline phosphatase less than 10 U/l, those who had no increase in bone mineral content measured with CT in L4 and those who got a femoral neck fracture during the period of therapy. In the overall group of 91 patients 20% were non-responders based on a serum alkaline phosphatase increase less than 10 U/l. Based on the changes in bone mineral content 40% were non-responders during the first year of treatment, 45% during the second year and 23% over the first plus second year. The impression is that patients with a femoral neck fracture have a higher increase in serum parathyroid hormone concentration than patients without fractures. The urinary excretion of fluoride has a better predictive value than the change in serum alkaline phosphatase concentration for the prediction of an increase in bone mineral content.

Fluoride in diet, drinking water and urine in relation to bone mineral density and incidence of fractures.
Background: Randomized controlled trials have shown that high fluoride doses increases both bone mineral density and skeletal fragility. The consequences of long-term low dose exposure to fluoride, primarily via drinking water, on bone health among the general public is however not clear. In the present study, we assessed associations of

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.

Epidemiological, clinical, and biochemical study of endemic dental and skeletal fluorosis in Punjab
The incidence of dental fluorosis in 46,000 children in the Punjab was assessed and compared with the fluoride content of their water supplies. Ten villages were selected for more detailed studies of skeletal as well as dental fluorosis. Factors other than the fluoride content of the drinking water which were found to influence

The genetic influence on bone susceptibility to fluoride
INTRODUCTION: The influence of genetic background on bone architecture and mechanical properties is well established. Nevertheless, to date, only few animal studies explore an underlying genetic basis for extrinsic factors effect such as fluoride effect on bone metabolism. MATERIALS AND METHODS: This study assessed the effect of increasing fluoride doses (0

"Pre-Skeletal" Fluorosis
As demonstrated by the studies below, skeletal fluorosis may produce adverse symptoms, including arthritic pains, clinical osteoarthritis, gastrointestinal disturbances, and bone fragility, before the classic bone change of fluorosis (i.e., osteosclerosis in the spine and pelvis) is detectable by x-ray. Relying on x-rays, therefore, to diagnosis skeletal fluorosis will invariably fail to protect those individuals who are suffering from the pre-skeletal phase of the disease. Moreover, some individuals with clinical skeletal fluorosis will not develop an increase in bone density, let alone osteosclerosis, of the spine. Thus, relying on unusual increases in spinal bone density will under-detect the rate of skeletal fluoride poisoning in a population.

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.,

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
