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

Recovery from skeletal fluorosis (an enigmatic, American case)
A 52-year-old man presented with severe neck immobility and radiographic osteosclerosis. Elevated fluoride levels in serum, urine, and iliac crest bone revealed skeletal fluorosis. Nearly a decade of detailed follow-up documented considerable correction of the disorder after removal of the putative source of fluoride (toothpaste). INTRODUCTION: Skeletal fluorosis, a crippling bone

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

Fluoride & Kidney Stones
It has long been suspected that fluoride may contribute to the formation of kidney stones. This suspicion has recently gained support from a study of an American man with skeletal fluorosis. According to the authors: "A new, important, medical problem (that seemed temporally related to cessation of fluoride exposure and subsequent negative calcium

Fluoride-Induced Damage to Gastric Mucosa in Human Clinical Trials
When fluoride has been used (at doses of 18-34 mg/day) as an experimental treatment for osteoporosis, gastric pain is one of the two main side effects consistently encountered. To better understand how fluoride causes this effect, researchers have sought to determine how fluoride affects the tissue that lines the gastrointestinal tract. In a

Fluoride as a Cause of Kidney Disease in Humans
Because the kidney is exposed to higher concentrations of fluoride than all other soft tissues (with the exception of the pineal gland), there is concern that excess fluoride exposure may contribute to kidney disease - thus initiating a "vicious cycle" where the damaged kidneys increase the accumulation of fluoride, causing

Fluoride Toothpaste: A Cause of Perioral Dermatitis
We have gathered clinical and historical data implicating fluoride dentrifices as an important etiologic factor in this dermatosis. The following two cases support this observation.
