Abstract
All cases of fluoride ingestion in children younger than 12 years old reported to the Rocky Mountain Poison Center between January 1 and December 31, 1986, were retrospectively reviewed. Eighty-seven cases were identified. Eighty-four cases involved accidental ingestion of dental fluoride products in the home (tablets, drops, rinses) in children 8 months to 6 years old. Two older children (8 and 9 years old) became symptomatic after fluoride treatment by a dentist. A 13-month-old child died after ingesting an unknown amount of sodium fluoride insecticide, the only insecticide exposure in our series. Postmortem total serum calcium value was 4.8 mg/dL (normal 8.8 to 10.3). No other patients had serious symptoms or sequelae. Twenty-six (30%) of 87 became symptomatic, with gastrointestinal symptoms (nausea, vomiting, diarrhea, abdominal pain) in 25 patients and drowsiness in 1. Only 3 patients became symptomatic later than 1 hour after ingestion. Analysis of data from 70 cases with sufficient information revealed that as the amount of fluoride ingested increased, the percentage of patients with symptoms increased. Not including the fatal case, 6 patients had serum calcium levels measured, and all were normal. Children who ingested up to 8.4 mg/kg of elemental fluoride in dental products had mild and self-limited symptoms, mostly gastrointestinal.

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

Allergy to fluoride
Six children and one adult exhibited various allergic reactions after the use of toothpaste and vitamin preparations containing fluoride. The following conditions were encountered: Urticaria, exfoliative dermatitis, atopic dermatitis, stomatitis, gastro-intestinal and respiratory allergy.

Fluoride-related bone disease associated with habitual tea consumption
Acquired osteosclerosis is a rare disorder of bone formation but an important consideration in adults with sclerotic bones or elevated bone density results. In such patients, malignancy, hepatitis C, and fluorosis should all be considered when making a diagnosis. We describe 4 patients evaluated at our Metabolic Bone Disease Clinic

Effect of deltamethrin and fluoride co-exposure on the brain antioxidant status and cholinesterase activity in Wistar rats
The study evaluated the effect of commercial preparation of deltamethrin, Butox®, and fluoride (F-) co-exposure on the brain antioxidant status and cholinesterase activity in rats. Group A was untreated. Group B was gavaged Butox®, providing deltamethrin at the dose rate of 1.28?mg per kg body weight per day. Group C

Combination of fluoride and endosulfan induced teratogenicity and developmental toxicity in Swiss albino mice exposed during organogenesis.
The present investigation was conducted to evaluate the teratogenic and developmental toxicity of fluoride and endosulfan alone and in combination in pregnant Swiss albino mice exposed during the organogenetic period (5-14 days) of gestation. Fluoride (25.1 mg/kg body weight in water) and endosulfan (1.8 mg/kg bw by oral intubation) when

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

Kidney Patients Are at Increased Risk of Fluoride Poisoning
It is well established that individuals with kidney disease are susceptible to suffering bone damage and other ill effects from low levels of fluoride exposure. Kidney patients are at elevated risk because when kidneys are damaged they are unable to efficiently excrete fluoride from the body. As a result, kidney patients

Fluoridation of drinking water and chronic kidney disease: Absence of evidence is not evidence of absence
A fairly substantial body of research indicates that patients with chronic renal insufficiency are at an increased risk of chronic fluoride toxicity. Patients with reduced glomerular filtration rates have a decreased ability to excrete fluoride in the urine. These patients may develop skeletal fluorosis even at 1 ppm fluoride in the drinking water.
