Abstract
In the search for a simple method of assessing the therapeutic efficacy of sodium fluoride, a prospective study of vertebral radiography during such treatment was carried out. Treatment of osteoporosis with sodium fluoride, calcium and vitamin D was found to enhance the vertical markings of the vertebral trabecular pattern in 69% of patients. This response was graded 1 (failure), 2 (good) and 3 (excellent); Grade 2 or 3 was attained after a mean treatment period of 31.7 months. Subsequent analysis of the vertebral fracture rate revealed that new vertebral fractures had occurred only in patients with Grade 1 and not in those with Grade 2 or 3. We recommend that treatment should aim at increasing the vertebral trabecular pattern to Grade 2 or 3 and that the duration of therapy should be approximately 30 months.

Sodium fluoride induced skeletal muscle changes: Degradation of proteins and signaling mechanism.
Highlights Sodium fluoride at low concentrations causes excessive proliferation of C2C12 myoblasts. Sodium fluoride causes production ROS and inflammatory cytokines in myoblasts and differentiating myotubes. Sodium fluoride at low concentrations causes hypertrophy of the differentiating myoblasts and activates PI3K/AKT signaling pathway. Ubiquitin-proteasome pathway plays a major role in sodium

The effects of fluoride on bone and implant histomorphometry in growing rats
The effects of fluoride at concentrations of 2.0 and 4.5 mM in drinking water on growth rate, vitamin D, water and mineral metabolism, bone histomorphometry, and osteoinduction of demineralized allogenic bone matrix (DABM) were compared in the rat. Whereas fluoride did not influence fluid intake or growth rate at the

Industrial fluoride pollution: Chronic fluoride poisoning in Cornwall Island cattle.
An aluminum plant on the south bank of the St. Lawrence river, southwest of Cornwall Island, Ontario, Canada, has emitted 0.816 metric tons of fluoride daily since 1973; considerably higher amounts were emitted from 1959 to 1973. The plant has been designated as the "major source of fluoride emissions impacting

Recent advances in cellular effects of fluoride: an update on its signalling pathway and targeted therapeutic approaches.
Fluoride is a natural element essential in minute quantities in human’s to maintain dental and skeletal health. However, the disease fluorosis manifests itself due to excessive fluoride intake mostly through drinking water and sometimes through food. At the cellular energetics level, fluoride is a known inhibitor of glycolysis. At the

Industrial Fluorosis of Farm Animals in England, Attributable to the Manufacture of Bricks, the Calcining of Ironstone, and to Enamelling Processes.
Front Page of Article IN the summer of 1938 one of us (F. B.) was called in by veterinary practitioners to advise on the possible causation of a "mysterious lameness of cattle" near Stewartby, in Bedfordshire. Clinical examination and proximity to a large concentration of brick kilns suggested " industrial fluorosis"

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.
