Abstract
Pharmacokinetic studies have revealed quantitative information about the bioavailability, rate of absorption, distribution, and clearance of fluoride following the use of fluoride-containing dentifrices, gels, varnishes, and solutions. It is concluded that following the use of topical fluoride products, variable amounts of fluoride are swallowed and absorbed into the systemic circulation–amounts which may be sufficient to produce acute or chronic side-effects. Pharmacokinetic data should, therefore, form part of the basis for the optimal and safe use of fluoride products. In addition, there is a need for future research to determine the kinetics of fluoride in the oral fluids after the application of topical fluoride agents and to determine the associated changes in the composition of the mineral components of the oral fluids.

Topical fluorides: effects on physiologic and biochemical processes
The ingestion of fluoride from dentifrices or mouthrinses can contribute substantially to the total daily intake of the ion, even in communities that provide optimally fluoridated drinking water. It is concluded that the frequent and unsupervised use of these products by children six years of age or younger, especially those living in

Fluoride and Oral Health.
In 1993, the World Health Organization convened an Expert Committee to provide authoritative information on the role of fluorides in the promotion of oral health throughout the world (WHO TRS 846, 1994). This present publication is a revision of the original 1994 document, again using the expertise of researchers from

Fluoride in dental products: safety considerations
This review summarizes the nature of acute fluoride toxicity, its time-course, and the fluoride doses that are involved. The generally accepted "certainly lethal dose" range for 70 kg adults, i.e., from 5 to 10 g of sodium fluoride or from 32 to 64 mgfluoride/kg, is discussed. Based on recent case reports of fluoride-induced fatalities, it is concluded

Using High Fluoride Concentration Products in Public Policy: A Rapid Review of Current Guidelines for High Fluoride Concentration Products.
Despite improvements in dental caries levels since the widespread introduction of fluoride toothpastes, it is still a disease which is considered to be a priority in many countries around the world. Individuals at higher risk of caries can be targeted with products with a high fluoride concentration to help reduce

Assessment of the influence of meal type on fluoride absorption due to ingestion of professionally applied gels
AIMS: The aim of this study is to assess the influence of eating, prior to application of professionally used gels, on the rate of fluoride absorption due to the ingestion of 1.23% acidulated phosphate fluoride (APF). MATERIALS AND METHODS: After fasting for 12 hours, 16 adult volunteers (> 65 kg) ingested

Fluoride Gels & Kidney Function
Scientists have found that the application of "Fluoride Gels" at the dental office causes very high spikes in the blood fluoride level. The high spikes in blood fluoride levels are a result of three factors: the high concentration of fluoride in the gel (= 12.3 mg of fluoride in each

Kidney: A potential target for fluoride toxicity
The kidneys are the organ responsible for clearing fluoride from the body. In the process of doing so, the kidneys are exposed to concentrations of fluoride that exceed, by a factor of 50, the concentration of fluoride in human blood. As such, the kidney have long been considered a potential

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.

Side Effects from Fluoride Gels: Gastric Distress
Gastric distress -- including nausea, pain, and vomiting -- is one the most common side effects from professional application of "fluoride gels" at the dentist. Patients receiving fluoride gels can swallow more than 20 mg of fluoride from a single treatment -- doses that far exceed the doses that can

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.
