Abstract
To gain a better understanding of how fluoride causes gastrointestinal distress, we conducted an experimental study on rabbits to evaluate damage to the gastroduodenal tissue by sodium fluoride. Young albino rabbits weighing 400-600 g were injected daily with 5, 10, 20, and 50 mg NaF/kg bw for fifteen weeks and then sacrificed. Histopathological examination of the duodenum revealed erosion and necrosis of surface mucosa, hemorrhages, necrosis of Brunner’s gland, clumped submucosa, and hypertrophy of muscles in muscularis mucosae in increasing severity according to the dose of NaF. Most noteworthy was the loss of mucosal layer in direct proportional to the amount of fluoride administered.

Early diagnosis and complete recovery from fluorosis through practice of interventions
OBJECTIVES: The objective of this communication is to disseminate scientific and technical information for early diagnosis of Fluorosis; recent developments in care and management of patients of Fluorosis. Material and Methods: Body fluids collected from patients suspected of Fluorosis referred by hospitals, samples of drinking water used by them are the

Enhancement of aluminum digestive absorption by fluoride in rats.
Aluminum, responsible of dialysis encephalopathy, is suspected to be involved in other neurological disorders such as Alzheimer disease. Absorption of aluminum from the digestive tract can be enhanced by the concommittant intake of substances such as citrate. We studied in rats and mice the interactions between fluoride and aluminum for

Sodium fluoride-induced gastric mucosal lesions: comparison with sodium monofluorophosphate
In a randomized double-blind study with two parallel groups of 10 male healthy volunteers each the response of gastric mucosa after a 7 days ingestion of sodium fluoride tablets (NaF) or sodium monofluorophosphate tablets (MFP) was compared. Gastroscopic evaluations were performed before treatment, day 1 and day 7. Simultaneously blood

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

Alteration in gastric secretion of rats administered NaF
The effects of sodium-fluoride (7681494) on gastric secretion were studied in rats. Male albino-rats were administered 25 milligrams per kilogram sodium-fluoride in their drinking water for 60 days. Selected rats were killed after 7, 15, 30, and 60 days, and stomachs were dissected out, the gastric juice collected, and the

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-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

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 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
