Abstract

Background: Fluorosis is an endemic condition with prevalence in 19 states and union territories in India. It is an urgent task to survey the fluorosis-related problems in these regions.

Objective: To study the clinical manifestations of water-born fluorosis among schoolchildren in Kaiwara village of India.

Methods: A cross-sectional study was conducted in all schoolchildren between 1st and 7th standard studying in Kaiwara village, Karnataka State, India. Parameters studied included fluoride ingestion through drinking water, fluoride excretion through urine, clinical features of fluorosis. These included dental staining, genu valgum, goiter, and conjunctival xerosis. Fluoride in water and urine samples was estimated using an ion meter.

Results: Of the 416 schoolchildren studied, 24.0% children had dental fluorosis, 11.4% children had genu valgum, 20.9% had goiter, and 10.3% had xerosis of the conjunctiva. One hundred children passed high levels of fluoride in urine, while 90% of water samples consumed by the local residents contained high levels of fluoride.

Conclusion: It was proved that water-born fluorosis is endemic in Kaiwara village. The endemic prevalence of the syndrome of fluorosis among school children was characterized by dental mottling, genu valgum, endemic goiter, and xerosis of the conjunctiva.

  • Fluorosis in some tribal villages of Dungarpur district of Rajasthan, India

    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

  • Endemic goiter associated with high iodine intake in primary school children in the Saharawi Arab Democratic Republic.

    The high prevalence of goiter in Saharan children visiting Asturias in the summer prompted us to study the problem in greater depth. Neck palpation was performed in a sample of 570 school children from the Saharawi Arab Democratic Republic. Weight, height, T4, thyroid-stimulating hormone and anti-thyroperoxidase antibodies in capillary blood were

    Objective: To investigate the effect of different concentrations of fluoride and iodine in drinking water on children's dental fluorosis and thyroid function. Methods: According to different concentration of fluoride and iodine in drinking water, four villages in two counties of Henan province were classified as high fluoride and iodine, high fluoride,

  • Fluorosis and iodine deficiency disorders in India.

    This review focuses on fluorosis and iodine deficiency disorders, two serious, highly prevalent metabolic disorders that are under-reported. These are caused by the two elements of the halogen family, fluorine and iodine. The former in excess and the latter in deficiency are the cause for concern. Excess fluoride (F–) consumption

  • 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.

  • The Relationship Between Fluoride Exposure & Goitre in South Africa

    As a general rule simple goitre, irrespective of the cause, can be very, or fairly, satisfactorily combated by an adequate increase in man's daily iodine intake, except when the enlargement of the gland is due to the ingestion of excessive amounts of fluorine. The only correct solution to fluorine-induced endemic goitre is the removal of this element from the drinking water.

  • 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

  • Fluoride Exposure Aggravates the Impact of Iodine Deficiency

    A consistent body of animal and human research shows that fluoride exposure worsens the impact of an iodine deficiency. Iodine is the basic building block of the T3 and T4 hormones and thus an adequate iodine intake is essential for the proper functioning of the thyroid gland. When iodine intake is inadequate during infancy and
