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.

Bone quality in fluoride-exposed populations: A novel application of the ultrasonic method.
Highlights A novel ultrasonic bone quality biomarker was tested in a population with low to high exposure to F.- Negative associations were found between F- exposure and bone quality Decreased bone quality reflects net bone loss, abnormal mineralization and altered collagen. The finding highlights that F- exposure has complex

Long term effects of sodium fluoride in osteoporosis
Our results demonstrate that the bone response to NaF treatment is a phase process: an increase in bone turnover is combined with an osteomalacia-like reaction during the first year of treatment. These metabolic observations are in close agreement with the histomorphometric data of Olah, Reutter and Schenk. By comparing the

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

Fluorosis increases the risk of postmenopausal osteoporosis by stimulating interferon y
Estrogen deficiency in postmenopausal women frequently activates osteoclasts (OC), accelerates bone resorption, and leads to osteoporosis (OP). Previous studies have demonstrated that interferon y (IFNy) could increase bone resorption and may be involved in postmenopausal OP. Fluorosis also increased the risk of fractures and dental fluorosis, and fluoride may enhance osteoclast formation and

Fluoride intake and cortical and trabecular bone characteristics in adolescents at age 17: A prospective cohort study.
OBJECTIVE: To investigate the associations between period-specific and cumulative fluoride (F) intakes from birth to age 17 years, and radial and tibial bone measures obtained using peripheral quantitative computed tomography (pQCT). METHODS: Participants (n = 380) were recruited from hospitals at birth and continued their participation in the ongoing Iowa Fluoride Study/Iowa Bone Development

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.
