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.

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

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.

Perioral dermatitis from high fluoride dentifrice: a case report and review of literature
Perioral dermatitis is a papulopustular eruption, commonly related to the inappropriate application of topical corticosteroids with occasional reports of inhaled corticosteroids and decreased personal hygiene. We present a case of a 45-year-old female with a one-year history of perioral dermatitis related to the use of highly fluoridated toothpaste commenced to

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

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

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.

Allergy to Fluorides
Rather than simply denying the validity of his reports, it would be to the advantage of all concerned to have them thoroughly analyzed. This could best be done if a small number of unbiased, qualified physicians, agreed upon by both "sides," would independently examine and diagnose several of the patients who are reportedly allergic to fluoride.

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 & Perioral Dermatitis
Perioral dermatitis (PD) is a common rosacea-like dermatitis that was never reported prior to the mid-fifties. Although it can affect both sexes and all ages, most patients are women ages 20-50 years. Patients with PD frequently report a pre-existing tendency to blush. This disease is most likely multifactorial in origin, and fluoride preparations in dentrifices probably have played a role as precipitator.

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,
