Abstract
Although the association between inflammatory bowel disease (IBD) and oral hygiene has been noticed before, there has been little research on prolonged fluoride exposure as a possible risk factor. In the presented cases, exposure to fluoride seems indirectly associated with higher incidence of IBD. Fluoride toxicology and epidemiology documents frequent unspecific chronic gastrointestinal symptoms and intestinal inflammation. Efflux genes that confer resistance to environmental fluoride may select for IBD associated gut microbiota and therefore be involved in the pathogenesis. Together these multidisciplinary results argue for further investigation on the hypothesis of fluoride as a risk factor for IBD.

Outbreak of acute fluoride poisoning caused by a fluoride overfeed, Mississippi, 1993.
OBJECTIVE: To determine the extent and confirm the cause of an August 1993 outbreak of acute fluoride poisoning in a small Mississippi community, thought to result from excess fluoride in the public water supply. METHODS: State health department investigators interviewed patrons of a restaurant where the outbreak first became manifest and

Exposure to fluoride in smelter workers in a primary aluminum industry in India
BACKGROUND: Fluoride is used increasingly in a variety of industries in India. Emission of fluoride dust and fumes from the smelters of primary aluminum producing industries is dissipated in the work environment and poses occupational health hazards. OBJECTIVE: To study the prevalence of health complaints and its association with fluoride level

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

Skeletal fluorosis mimicking seronegative arthritis
Fluorosis is endemic in certain parts of the world, especially the Asian subcontinent (1). We report an unusual presentation of fluorosis mimicking seronegative spondyloarthritis. Although fluorosis is known to cause irritable bowel syndrome-like disorder and joint pain, this could be wrongly diagnosed as a case of seronegative arthritis. Case report A 35-year-old

Intestinal barrier damage involved in intestinal microflora changes in fluoride-induced mice.
Highlights Fluoride inhibited the secretion of glycoproteins. Fluoride induced relative number of goblet and mast cells down-regulate. Fluoride inhibited epithelial cells proliferation. Fluoride induced cecal epithelial barrier damages. Fluoride interfered the composition of intestinal microflora. Intestinal microflora play an important role in maintaining the homeostasis of the intestinal microenvironment, but fluoride-induced

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 & 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
