Abstract

The prevalences of dental and skeletal fluorosis were observed in fifteen tribal villages of the Dungapur district of Rajasthan where the fluoride (F) concentration in drinking waters varies from 0.3 to 10.8 ppm. At 1.40 and 6.04 ppm mean F concentrations, 25.64% and 84.43% of school children (<16 years), and 23.91% and 96.87% of adults, respectively, were found to be affected with dental fluorosis. The maximum prevalence of dental fluorosis (76.43%) was observed in the 17 to 22 years age group. No significant correlation was found between dental fluorosis prevalence and gender. At these same F concentrations, 4.35% and 63.02% of adults (>21 years), respectively, were showing evidence of skeletal fluorosis. The prevalence of skeletal fluorosis was comparatively higher in males and increased with higher F level and age. None of the fluorotic subjects showed evidence of genu valgum syndrome or goitre. Radiological findings of other deformities in fluorotic subjects were found.

These standards include the maximum contaminant level goal (MCLG), the maximum contaminant level (MCL), and the secondary

  • 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.

  • Fluorine in the Aetiology of Endemic Goitre

    The distribution of endemic goitre in the Punjab and in England is related to the geological distribution of fluorine and to the distribution of human dental fluorosis (mottled enamel). Inquiry showed the presence of dental fluorosis among school-children in two areas of Somerset where two previous observers had recorded a high incidence of goitre, and the absence of dental fluorosis in an adjoining area selected as control where endemic goitre was absent.

  • Fluoride, Water Hardness, and Endemic Goitre

    Variations in goitre prevalence were found to correlate closely with the fluoride content (p=0-74; P<0-01) and with the hardness (p=0.77; P<0-01) of the water in each village. The effects of fluoride and water hardness seem to be independent.

  • Fluoride & Goiter

    Goitre (aka goiter) is an enlargement of the thyroid gland that in some cases can produce visible swelling in the neck. The main cause of goitre is iodine deficiency. Goitre can also be caused by other things, including hypothyroidism and substances that cause goitre (goitrogens). Since as far back as the
