Abstract
The topical application of sodium fluoride to abraded rat skin produced several morphological and biochemical effects. Related to the degranulation of dermal mast cells, skin histamine concentration was increased, fluorides were absorbed into the skin, and deposited mainly kin mitochondria. Dermal histamine binding was decreased for both H1 and H2 receptors with reduced binding sites, but epidermal adenyl cyclase was activated by fluorides. The response of the rat skin to fluorides involves a sequence of changes by which the potentiation of an inflammatory response also involves alterations in specific histamine receptors and a histamine-specific adenyl cyclase system.

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

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

Fluoride tooth paste: a cause of perioral dermatitis
Since its description in 1957 by Frumess and Lewis as a “light-sensitive seborrheid,” perioral dermatitis (PD) has continued to be a perplexing entity. (1) Many causes have been postulated, including sunlight sensitivity, birth control pills, emotional stress, fluorinated steroid creams, Candida albicans, and rosacea. We have gathered clinical and historical data implicating

Contact dermatitis and stomatitis due to amine fluoride
Case Report For prevention of dental caries, a 17-year-old boy had intermittently used a gel containing different fluoride compounds over a period of 2 years. In the last 2 months, 1 to 2 days after application, he had developed itchy perioral erythematous papules and plaques, with vesicles of the oral mucosa.

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

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.

Allergy and Hypersensitivity to Fluoride
there are reasonable grounds for concluding that there are individuals in whom allergy or hypersensitivity to fluoride has been demonstrated.

Allergic Reactions from Fluorides
Six cases are described with allergic manifestations from fluorides. The symptoms were reproduced by administering an aqueous fluoride solution either by ingestion, injection or local application. Control tests had no such effect. The patients had no way of knowing which solution contained fluoride.

Is the Ingestion of Fluoride an Immunosuppressive Practice?
This paper records several observations which suggest that habitual ingestion of small doses of fluoride, even as small as the 1 mg/L contained in fluoridated water, may decrease the function of the immune system.

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.
