Studies of human gastric mucosa after application of 0.42% fluoride gel

Dental prophylaxis with APF gels (1.23%) may cause gastric distress as a side-effect. This gastric irritation is probably due to a direct toxic effect of fluoride (F), swallowed in conjunction with the treatment, on the gastric mucosa. The aim of the present study was to investigate whether--and to what extent--a

Effect of fluoride on uptake of D-glucose by isolated epithelial cells of rat intestine.

Inhibition on uptake of D-glucose by isolated intestinal epithelial cells (IIEC) was observed when the fluoride concentration ranged between 0.25 and 5 mM. Active transport was almost completely inhibited at 5 mM. When CaCl2 was added to fluoride, the inhibitory effect on glucose uptake was abolished. Preincubation of IIEC with

Fluorine Intoxication: A Clinical-Hygienic Study with a Review of the Literature and Some Experimental Investigations

Prenatal and postnatal ingestion of fluorides: fourteen years of investigation -- final report

Three different sources of fluoride were used in this study. The tablets containing 1.0 mgm fluorine ion from CaF2; 1.2 mgm fluorine ion, from NaF and 0.825 mgm fluorine ion from Na2PO3F, each. These values were chosen so that each tablet would contain approximately the same amount of the ion

Effect of Fluoride on Small Intestine Morphology and Serum Cytokine Contents in Rats.

This study aimed to determine the effect of excessive fluoride (F) on the morphological characteristics of the small intestine and the contents of serum cytokines in rats. A total of 48 3-week-old healthy female Sprague-Dawley rats were randomly divided into four groups (n?=?12). The control group was given deionized distilled

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-Induced Gastric Symptoms in Human Clinical Trials

In studies where fluoride has been used (at doses of 18-34 mg/day) as an experimental drug for the treatment of osteoporosis, gastrointestinal disturbances are one of the two main side effects consistently encountered. The following are some of the accounts from the published literature: "The use of fluoride in the prophylaxis or

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

Gastrointestinal Problems Among Individuals with Skeletal Fluorosis

Humans suffering from skeletal fluorosis are known to suffer from an increased occurrence of gastrointestinal disorders. When fluoride intake is reduced, these gastrointestinal problems are among the first symptoms to disappear. The following are some of the studies that have examined this issue: "It is clear from the observations presented in this article

Fluoride & Gastrointestinal System: The Importance of Fluoride Concentration in Stomach

The following is an excerpt from the National Research Council's (2006) review of fluoride toxicity: "It is important to realize that GI effects depend more on the net concentration of the aqueous solution of fluoride in the stomach than on the total fluoride dose in the fluid or solid ingested. The
