Abstract
The clinical manifestation of fluorosis has become rare over the past years. Although the use of fluoride medication in osteoporosis therapy remains controversial, past study results have led to a reduction in fluoride prescriptions. Several studies have shown minor biomechanical properties of newly built woven bone compared to original bone. Despite new prescription protocols, fluoride therapy should not be disregarded in the anamnesis of osteoporosis patients. In addition to conventional diagnostics in fluorosis, new techniques such as microanalysis and micro-CT-analysis show a diagnostic benefit. In this case, the edx-microanalysis results show an F concentration of over 1.0 wt% in bone. The ratio of bone to tissue volume, evaluated by micro-CT, is clearly elevated at 46% BV/TV. The histopathological preparation of the femoral head has made the possible effects of fluoride medication on bone visible and quantifiable. A direct causal relationship between coxarthrosis and fluoride medication, found both in our patient as well as in the literature, has not been demonstrated. In order to better understand the broad effects of fluoride medication in combination with coxarthrosis more studies are needed.

Plasma fluoride level as a predictor of voriconazole induced periostitis in patients with skeletal pain
BACKGROUND: Voriconazole is a triazole antifungal medication used for prophylaxis or to treat invasive fungal infections. Inflammation of the periosteum resulting in skeletal pain, known as periostitis, is a reported side effect of long-term voriconazole therapy. The tri-fluorinated molecular structure of voriconazole suggests a possible link between excess fluoride and

A roentgenologic study of a human population exposed to high-fluoride domestic water; a ten-year study
As shown in Table 1, a limited number of participants from both Bartlett and Cameron showed some degree of roentgenographic bone change but, in general, these changes were minimal. There was a larger number with no observable change in the ten-year interval, a fact disregarded or unreported in most fluoride

Exacerbation of rheumatoid arthritis by sodium fluoride treatment of osteoporosis
Recent studies have suggested that sodium fluoride therapy may be an effective treatment for vertebral osteoporosis. Unfortunately, the high frequency of side effects may limit the use of this treatment modality. This report documents the repeated exacerbation of rheumatoid arthritis on three occasions after the initiation of sodium fluoride therapy. This apparent complication of

Ancient and recent evidence of endemic fluorosis in the Naples area
Endemic fluorosis induced by high concentrations of natural fluoride in groundwater and soils is a major health problem in several countries, particularly in volcanic areas. The early stages of skeletal fluorosis, a chronic metabolic bone and joint disease rarely considered in palaeopathological diagnoses, are often misdiagnosed in endemic areas. In

[Generalized osteopathy with pathological fractures in a patient with long-term exposure to fluorine-containing plastics].
In a 68-year-old man with a painful syndrome of the lower extremities which began at the age of 64 years, workup revealed a generalized osteopathy with sclerosis of the axial skeleton and osteopenia at the extremities associated with pathologic fractures. The occupational history showed exposure to several synthetics such as

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.

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.

"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.
