Abstract
A prospective case controlled study was conducted to evaluate the role of fluoride as a possible aetiological factor for non-ulcer dyspepsia (NUD). Twenty patients with NUD and 10 age and sex matched healthy controls were subjected to clinical evaluation, upper gastrointestinal endoscopy and biopsies from the gastric antrum and duodenum. The antral and duodenal mucosa was subjected to a rapid urease test for Helicobacter pylori and histological and electron microscopic examinations. Fluoride levels in the drinking water, serum and urine were estimated using a ION 85 ion-analyser. These levels were significantly higher in patients with NUD than in controls (P less than 0.05). Histological abnormalities in the antral and duodenal mucosa were seen in 14 patients (70%) with NUD and 1 control subject (10%) (P less than 0.05). Electron microscopic abnormalities in the mucosal cells were seen in all patients with NUD but in none of the controls (P less than 0.01). The fluoride levels in serum and urine correlated with the symptoms, histological and electron microscopic abnormalities (P less than 0.05). It was concluded that chronic exposure to fluoride may result in NUD and should be considered in patients where other known cause of dyspepsia have been excluded.

Apoptotic and Degenerative Changes in the Enteric Nervous System Following Exposure to Fluoride During Pre- And Post-natal Periods.
Children born in fluorosis endemic areas usually suffer from gastrointestinal complications and are unable to attain normal growth as per their age group. The enteric nervous system (ENS) controls gut movement and functions. It is highly vulnerable to any ingested toxins. Based on observations, it was hypothesized that fluoride exposure

Tissue response of gastric mucosa after ingestion of fluoride
Fluoride has been used successfully to prevent dental caries and has also been used to treat osteoporosis. Doses of sodium fluoride of about 50 mg a day have long term beneficial effects on the mineral content of bone and the incidence of fracture. (1) These doses, however, have resulted in

Health problems in fluoride endemic areas of Gaya District
Fluoride (F) was estimated in the groundwater of six blocks (Bodh Gaya, Manpur, Wazirganj, Belaganj, Amas, and Bankebazar) of Gaya District, Bihar, for different physio-chemical properties e.g. pH, total dissolved solids(TDS), conductivity, turbidity, total hardness (TH), calcium, magnesium, iron and fluoride. Morever 93 blood samples from different age groups including

Clinical and hygienic evaluation of the combined effect of vibration and fluoride in humans
By L. Ya. Tartatovskaya, G.N. Samokhvalova, A.G. Antropov Medical Science Centre of Prophylactics and Protection of the Health Workers in Industrial Enterprises, Ekaterinburg, Russia. The study of the combined action of vibration and intense noise, muscular loads and cooling has made it possible to assess the probability of the development of vibration

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

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

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

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-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
