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.

Fluoride intoxication from drinking water (a report of 52 cases)
In previous publications, cases of incipient fluorine 1) poisoning from drinking artificially fluoridated water at the 1 ppm concentration were reported. A specific disease pattern could be discerned closely tallying with what has b??n observed in industrial poisoning from fluorine intake at higher levels. There are three groups of symptoms: 1. Those

[Etiology and treatment of postoperative spinal cord injury for patients undergoing laminectomy for fluorosis thoracic canal stenosis].
OBJECTIVE: To elucidate the etiology of postoperative spinal cord injury (PSCI) for patients undergoing laminectomy for fluorosis thoracic canal stenosis (FTCS) and summarize the methods of diagnosis and treatment. METHODS: From 2006 to 2009, a total of 192 FTCS cases underwent laminectomy. Among them, 16 cases with gradual postoperative neural deterioration were finally

Industrial skeletal fluorosis: preliminary report on 61 cases from aluminum smelter
SchIegel presented data on 61 cases of skeletal f1uorosis among workers of a Swiss aluminum factory. Of 350 cases ofìndustrial fluorosis reported in the world's literature, approximately 20 occcured in the smelting area of the aluminum industry. For processing aluminum from clay, cryolite (NaAlF6) is used as a fluxing agent.

Association of fluoride in water for consumption and chronic pain of body parts in residents of San Kamphaeng district, Chiang Mai, Thailand
OBJECTIVE: To assess the dose response of fluoride exposure from water and chronic pain. METHODS: Using a retrospective cohort design, the study was conducted in two sub-districts of San Kamphaeng district, Poo-kha and On-tai. Five hundred and thirty-four residents aged ?50 years of age were interviewed about their sources of drinking

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.

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.
