Most cases of fluoride poisoning arise because people consume groundwater that’s filled with it. Dental fluorosis is extensively described by toxicologists as the first visible sign of chronic fluoride poisoning [Taber, CW. Davis Co., Philadelphia, PA, 1994]. Although fluoride is safe for dental health at low concentrations, sustained consumption of large amounts of soluble fluoride salts is dangerous. Taber's Cyclopedic Medical Dictionary, F.A. Chronic Fluoride Toxicity: Dental Fluorosis Pamela DenBesten and Wu Li Department of Orofacial Sciences, School of Dentistry, University of California, San Francisco, by Waldbott George L, MD+, , 1998, Fluoride, 31:1, 13-20. Acute toxicity (poisoning) is by far the most dangerous and requires immediate medical attention. These studies reveal that there are direct adverse effects on the kidneys by excess fluoride, leading to kidney damage and dysfunction. What Is Fluoride Toxicity? Controversially, though fluoride prevents tooth decay at certain levels it is also toxic to the body. Chronic poisoning from most toxic agents is rarely diagnosed by physicians in its initial stage. Chronic fluoride poisoning can result from: fluoride levels of 1.8 ppm to 2.0 ppm combination of several fluoride sources over a period of time ingestion of high fluoride levels in water. Examples of fluoride toxicity demonstrate its serious threat. May-Jun 1998;65(3):371-81. doi: 10.1007/BF02761130. However, dental fluorosis related to F varnish applications could practically be ruled out, as these applications are sporadic, and dental fluorosis is caused by the chronic absorption of F that is contains bacteria, which is fed by foods we a soft, white sticky mass This review covers nearly 100 years of studies on the toxicity of fluoride on human and animal kidneys. Human salivary acid phosphatase is diminished by half when exposed to 3.8 ppm of fluoride, while blood enzyme cholinesterase is inhibited by 61 per cent on exposure to 0.95 ppm fluoride-a level within recommended levels. The first sign of fluoride toxicity is dental fluorosis, which is on the rise in the USA. In chronic fluoride poisoning, this diminished enzyme activity accounts for muscular weakness and even muscle wasting. The chosen IDLH, therefore, has been estimated from the human acute lethal dose of 5 grams of sodium fluoride [Largent 1961 cited by AIHA 1965]. Fluoride toxicity is a condition in which there are elevated levels of the fluoride ion in the body. Authors M Teotia 1 , S P Teotia, K P Singh. With the exception of the pineal gland, the kidney is expose … Dental plaque. Basis for original (SCP) IDLH: No data on acute inhalation toxicity are available on which to base the IDLH for fluorides. On average, the concentration of fluoride in … The EPA suggests a level of 0.5 to 1.0mg/L. toxic.4 Regarding chronic toxicity, the only adverse effect to be expected would be the development of dental fluorosis. Excess exposure to large amounts of fluoride can have adverse effects on our health. Research thus far indicates that the manifestations of fluorosis are irreversible. Ideally the person or caregivers should call the National Poison Control Center as well for further advice. The approach to treating fluoride poisoning depends on whether it is acute (sudden, large dose) or chronic (small dose over long periods). Endemic Chronic Fluoride Toxicity and Dietary Calcium Deficiency Interaction Syndromes of Metabolic Bone Disease and Deformities in India: Year 2000 Indian J Pediatr. Fluoride toxicity is estimated to be lethal at 5 to 10g; ingestion can produce gastrointestinal discomfort at much lower levels (0.2mg/kg (body weight)). Most systemic poisons induce vague, subtle symptoms before the appearance of features characteristic of a particular kind of poisoning.
