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.

    In pursuit of former observations on hydrofluorosis the authors conducted an investigation concerning the incidence of goiter and the function of the thyroid gland in subjects with hydrofluorosis from Aquaviva Platani, a large endemic center of Sicily. To evaluate thyroid function, radio-iodine uptake and the conversion index (PBI) with 131I

  • 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

  • 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.

  • 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.

    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.
