Abstract

As described recently in Fluoride, horses on artificially fluoridated water (AFW) developed chronic fluoride poisoning. This report describes an allergic manifestation as an addition to the classical signs of fluorosis, viz., urticaria. The skin lesions disappeared promptly when an affected horse was removed from AFW and returned promptly when the horse was returned to AFW. These reversible changes attest to the highly allergenic potential of fluoride.

  • Allergic reactions from fluorides

    In a discussion of drug allergy it is necessary to distinguish between intolerance and allergy to drugs. One represents intoxication, the other is characterized by wheal formation, eosinophilia and other features of an allergic reaction. Gastric irritation, for instance, or acne from iodides or bromides represent intolerance to these drugs

  • Symptoms experienced during periods of actual and supposed water fluoridation

    Fluoridation of water is a controversial measure because of the suspicion that it has harmful effects on health. Opinions differ as to the reality of these fears. In Kuopio, after distressing disputes over the fluoridation issue, the City Council decided to stop fluoridation at the end of 1992. In fact,

  • Vulvar Pagets disease: recovery without surgery following change to very low-fluoride spring and well water

    A case report of a Caucasian female born in 1927 is presented in which rapid recovery from vulvar extramammary Paget’s disease (EMPD) without surgical intervention occurred following an abrupt change from fluoridated/chlorinated tap water (0.9- 1.0 mg F–/L) to low-fluoride spring and well water (both <0.1 mg F–/L) for drinking,

  • Prenatal and postnatal ingestion of fluorides: fourteen years of investigation -- final report*.

    SUMMARY Data is presented showing that fluoride ingested by gravid women enters the maternal circulation, is stored in the placenta and passes through the placental barrier to enter the foetal blood supply. Evidence is presented that the fluoride in the foetal blood supply affects the developing teeth to make them more resistant

  • Allergy and hypersensitivity to fluoride

    A review of the literature was undertaken in response to four recent reviews which found that the evidence that fluoride was an allergen was unconvincing. Reports were found of urticaria, contact dermatitis and stomatitis occurring in response to fluoride, settling on the withdrawal of fluoride and recurring with appropriate challenges.

  • Factors which increase the risk for skeletal fluorosis

    The risk for developing skeletal fluorosis, and the course the disease will take, is not solely dependent on the dose of fluoride ingested. Indeed, people exposed to similar doses of fluoride may experience markedly different effects. While the wide range in individual response to fluoride is not yet fully understood, the following are some of the factors that are believed to play a role.

    We have gathered clinical and historical data implicating fluoride dentrifices as an important etiologic factor in this dermatosis. The following two cases support this observation.

  • 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

  • Physician's Desk Reference: Fluoride Hypersensitivity

    The following are excerpts from various editions of the Physicians' Desk Reference (PDR). "In hypersensitive individuals, fluorides occasionally cause skin eruptions such as atopic dermatitis, eczema or urticaria. Gastric distress, headache and weakness have also been reported. These hypersensitivity reactions usually disappear promptly after discontinuation of the fluoride. In rare cases,

  • Hypersensitive Reactions to Topical Fluorides

    Ever since fluoride toothpastes were introduced in the mid 1950s, studies in the scientific literature have documented adverse skin reactions from the use of topical fluoride products such as toothpaste. These skin reactions include: perioral dermatitis, stomatitis, and urticaria. Although many dermatologists now consider fluoride toothpaste to be a common cause of perioral dermatitis, the dental community
