Abstract
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. It is concluded that the four reviews were seriously incomplete in their coverage of the literature, and that when a more complete examination is made there are reasonable grounds for concluding that there are individuals in whom allergy or hypersensitivity to fluoride has been demonstrated. The sources of fluoride included those used in the fluoridation of community water supplies.

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,

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

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 intoxication from drinking water (a report of 52 cases)
In previous publications, cases of incipient fluorine 1) poisoning from drinking artificially fluoridated water at the 1 ppm concentration were reported. A specific disease pattern could be discerned closely tallying with what has b??n observed in industrial poisoning from fluorine intake at higher levels. There are three groups of symptoms: 1. Those

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

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.

Kidney Patients Are at Increased Risk of Fluoride Poisoning
It is well established that individuals with kidney disease are susceptible to suffering bone damage and other ill effects from low levels of fluoride exposure. Kidney patients are at elevated risk because when kidneys are damaged they are unable to efficiently excrete fluoride from the body. As a result, kidney patients

Skeletal Fluorosis & Individual Variability
One of the common fallacies in the research on skeletal fluorosis is the notion that there is a uniform level of fluoride that is safe for everyone in the population. These "safety thresholds" have been expressed in terms of (a) bone fluoride content, (b) daily dose, (c) water fluoride level, (d) urinary fluoride level, and (e) blood fluoride level. The central fallacy with each of these alleged safety thresholds, however, is that they ignore the wide range of individual susceptibility in how people respond to toxic substances, including fluoride.

Mayo Clinic: Fluoridation & Bone Disease in Renal Patients
The available evidence suggests that some patients wtih long-term renal failure are being affected by drinking water with as little as 2 ppm fluoride. The finding of adverse effects in patients drinking water with 2 ppm of fluoride suggests that a few similar cases may be found in patients imbibing 1 ppm, especially if large volumes are consumed, or in heavy tea drinkers. The finding of adverse effects in patients drinking water with 2 ppm of fluoride suggests that a few similar cases may be found in patients imbibing 1 ppm, especially if large volumes are consumed, or in heavy tea drinkers and if fluoride is indeed the cause. It would seem prudent, therefore, to monitor the fluoride intake of patients with renal failure living in high fluoride areas.

Fluoridation of drinking water and chronic kidney disease: Absence of evidence is not evidence of absence
A fairly substantial body of research indicates that patients with chronic renal insufficiency are at an increased risk of chronic fluoride toxicity. Patients with reduced glomerular filtration rates have a decreased ability to excrete fluoride in the urine. These patients may develop skeletal fluorosis even at 1 ppm fluoride in the drinking water.
