Conclusion:
1. During the treatment with a total dose of 21 grams of fluoride in a two years period further compression fractures of vertebrae were noticed in 5 or 23 cases. No conclusion can be drawn of course from further compression fractures about the effectiveness of treatment. Concerning the peripheral skeleton an average decrease of the bone mineral content of the radius was observed.
2. The histological picture of the bone biopsies show on an average a positive influence of treatment after the mentioned dose and time.
3. Taking into consideration all parameters, an analysis of the individual cases shows a progression in 4 cases, an obvious amelioration of osteoporosis in 6 cases and in 13 cases nearly unchanged findings indicate no progression of the disease.

Studies on osteoporosis III. Effect of estrogens and fluoride
Total skeletal calcium levels were determined in female mice with the aid of whole body neutron activation analysis. Three months treatment with heparin produced significant osteoporosis in C3-H/St(Ha) mice but not in C57/BL6 (J) mice. Treatment with a conjugated natural estrogen preparation (Premarin) prevented heparin accelerated osteoporosis, but high level

Effects of fluoride treatment on bone strength
Bone mass and architecture in appendicular and most axial sites is controlled primarily by the tissue-loading history. We introduce a conceptual framework for understanding how fluoride treatment alters this control and can cause systemic increases in bone mass. Due to possible adverse influences of fluoride on the mineralized tissue physical

Associations of fluoride intake with children's cortical bone mineral and strength measures at age 11.
OBJECTIVES: There is strong affinity between fluoride and calcium, and mineralized tissues. Investigations of fluoride and bone health during childhood and adolescence show inconsistent results. This analysis assessed associations between period-specific and cumulative fluoride intakes from birth to age 11, and age 11 cortical bone measures obtained using peripheral quantitative

Fluoride pharmacokinetics and changes in lumbar spine and hip bone mineral density
Debate about the use of fluoride for the treatment of vertebral osteoporosis has centered not only on whether fluoride treatment decreases vertebral fractures, but also the interindividual vertebral bone mineral density (BMD) response, the potential for nonvertebral fractures, as well as side effects and tolerability. These effects may be dose

Radiological spectrum of endemic fluorosis: relationship with calcium intake
Skeletal fluorosis continues to be endemic in many parts of India. Osteosclerosis and interosseous membrane calcification have long been regarded as hallmarks of this disease. Our study showed in addition a wide variety of radiological patterns: coarse trabecular pattern, axial osteosclerosis with distal osteopenia and diffuse osteopenia. Subjects with osteopenic changes had

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.

"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.
