Abstract
In experiments with 76 rats it was demonstrated that withdrawal of fluoride from fluoride-intoxicated rats caused an improvement in the interstitial inflammation and a marked reduction of the dilated convoluted tubules and Henle loops of the kidney.

Pharmacokinetic aspects of topical fluorides
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

Diagnosis of fluorosis and recovery through easy to practise interventions.
The objectives of the present study were to highlight (i) how to diagnose fluorosis, due to fluoride ion (F) toxicity, in out-patient departments, by retrieving the history and through tests and (ii) the interventions available for recovery. In patients suspected of fluorosis, the F levels were investigated in samples of

Fluoride exposure and kidney and liver function among adolescents in the United States: NHANES, 2013–2016.
Highlights Plasma fluoride concentrations are associated with kidney and liver parameters among United States (U.S.) adolescents Higher water fluoride concentrations are associated with lower blood urea nitrogen among U.S. adolescents Fluoride exposure may contribute to complex changes in kidney and liver related parameters among U.S. adolescents Altered kidney and/or liver

[An investigation on the effect of Rosa roxburghii tratt juice on chronic fluorosis and its mechanism].
Improved the general condition of chronic fluorosis but had no effect on dental fluorosis enhanced the excretion of fluorine and lowered the fluorine content of serum and bone which has been raised during fluorine intoxication; increased serum vitamin C and protected collagen as manifested by declin[e] of urinary hydroxyproline; inhibited

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 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 as a Cause of Kidney Disease in Animals
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 in

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 & 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
