Abstract

The prevalence of dental and skeletal fluorosis was determined among children of Kheru Nayak Thanda of Gulbarga district, where the fluoride concentration in drinking water ranges from 0.6 to 13.4 ppm and the water has low levels of copper and zinc. These children were investigated clinically, radiologically and biochemically. The study revealed that 89% of the children had dental fluorosis and 39% exhibited skeletal fluorosis. Serum samples of these children showed elevated levels of alkaline phosphatase (ALP), alanine transaminase (ALT), aspartate transaminase (AST), and decreased levels of total protein, albumin, and potassium. Radiographic changes suggestive of osteoporosis, osteosclerosis, and genu valgum were observed.

    Radiographs of 80 patients with severe endemic fluorosis of coal-burning type [CBEF] - 49 males and 31 females aged 30 to 70 years - were analysed to examine the changes to the bone substance, peripheral structure of bone, and joints. The changes to bone substance were: 1) osteosclerosis type, 62

  • FRZB1 rs2242070 polymorphisms is associated with brick tea type skeletal fluorosis in Kazakhs, but not in Tibetans, China.

    Skeletal fluorosis is a metabolic bone and joint disease caused by excessive accumulation of fluoride in the bones. Compared with Kazakhs, Tibetans are more likely to develop moderate and severe brick tea type skeletal fluorosis, although they have similar fluoride exposure. Single nucleotide polymorphisms (SNPs) in frizzled-related protein (FRZB) have

    A cross-sectional survey of 18,621 adults of both sexes living in rural tribal areas of the Dungarpur and Udaipur districts of Rajasthan, India was conducted to correlate the prevalence of osteo-dental fluorosis with nutritional status, living habits, and occupation. The mean fluoride (F) concentration in drinking water sources ranged from

  • Skeletal fluorosis. A report of two cases

    Two illustrative cases of patients with skeletal fluorosis and classic radiographic changes are presented. One patient demonstrated a progressive paraparesis, while the other was diagnosed incidentally on routine radiographs. A review of the literature, treatment, and histologic findings are presented.

    A survey was done of the prevalence of dental fluorosis among children aged 7-16 years and the occurrence of skeletal fluorosis among adults aged 40-60 years living in regions in Senegal where fluoride concentrations in the drinking water ranged from less than 0.1 to 7.4 mg/l. In the area where the fluoride concentration

  • 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.

  • Mayo Clinic: Fluoridation & Bone Disease in Renal Patients

    The available evidence suggests that some patients wtih long-term renal failure are being affected by drinking water with as little as 2 ppm fluoride. The finding of adverse effects in patients drinking water with 2 ppm of fluoride suggests that a few similar cases may be found in patients imbibing 1 ppm, especially if large volumes are consumed, or in heavy tea drinkers. The finding of adverse effects in patients drinking water with 2 ppm of fluoride suggests that a few similar cases may be found in patients imbibing 1 ppm, especially if large volumes are consumed, or in heavy tea drinkers and if fluoride is indeed the cause. It would seem prudent, therefore, to monitor the fluoride intake of patients with renal failure living in high fluoride areas.

  • Skeletal Fluorosis in the U.S.

    Although there has been a notable absence of systematic studies on skeletal fluorosis in the U.S., the available evidence indicates that the consumption of artificially fluoridated water is likely to cause skeletal fluorosis and other forms of bone disease in people with kidney disease and other vulnerable populations.
