  • Enhancement of inflammation by fluorides

    Application of ammonium fluoride under an occlusive patch to the abdomen of a rabbit converts a simple scratch into a double row of sterile pustules. Sodium fluoride produces a similar response, but ammonium chloride does not produce pustules. . . . It appears that tissue damage and the presence of fluorides

  • Perioral dermatitis

    Since its description in 1957 by Frumess and Lewis (1) as a "light-sensitive seborrheid," perioral dermatitis (PD) has been a perplexing entity. It characteristically presents as a chronic eruption consisting of papules and pustules that develop on irregular areas of erythema and edema. the eruption is most prominent in the

  • The effect of stannous fluoride and stannous chloride on inflammation

    Scratches were made to the depth of the upper dermis on the abdomen of rabbits. The scratches were covered by patch tests for 18 hours with solutions of stannous fluoride or stannous chloride. Both these substances produced a destructive reaction with intraepidermal polymorphonuclear leukocyte pustules occurring on each side of

  • NaF skin reaction to topical fluoride: metabolic and histological changes

    Topical and systemic administration or contact with fluorides has produced various forms of cutaneous reactivity. These studies, conducted with 150-400 g. Sprague-Dawley rats, investigated the effect of topical application of NaF to a shaved, epidemal abraded region (5 em.) of dorsal skin. After 24 hrs. NaF (1%) produced inflammation of

  • Contact urticaria from sodium fluoride

    Sodium fluoride (NaF) is. used for the treatment and prevention of dental caries. Its application to the teeth makes the dental enamel more resistant to acid. In some communities, it is added to the water if the geographical area lacks sufficient fluoride. Another method of preventing dental caries is the

    I feel that I should share with my colleagues in dermatology an observation relative to the treatment of problem acne.

  • Does Fluoride Ingestion Affect Developing Immune System Cells?

    Considerations, supported by some published experimental evidence, suggest that fluoride released during the resorption of high-fluoride bone may produce detrimental effects not only on bone cells but on developing cells of the immune system.

  • Allergy to Fluoride

    Six children and one adult exhibited various allergic reactions after the use of toothpaste and vitaimin preparations containing fluoride. The following conditions were encountered: Urticaria, exfoliative dermatitis, atopic dermatitis, stomatitis, gastro-intestinal and respiratory allergy.

  • Prenatal and postnatal ingestion of fluorides - A progress report.

    The cases described indicate that certain patients react unfavorably to fluoride therapy. Whether the fluorine acts as an allergen after short term use or whether the fluorine acts as an intoxicant after many months of use, is unknown and should be determined.

  • Fluoride Dentrifice and Stomatitis

    Statistical data of 133 patients who have been using fluoride dental cream or powder have been presented. Each has developed intraoral ulcerative lesions. Many have been treated for other complaints without clearance of the lesions. Age is not significant. Repeated insults with the fluoride dentrifices produced increasingly severe excoriations. There seems to be nothing specific about the lesions to differentiate them from other diseases of an oral nature.
