Abstract
In a study involving 2200 patients the inorganic plasma fluoride concentration (IPFC) increased with increasing age. In a fluoridated (1 ppm) community this increase was more pronounced than in a low fluoride (0.2 ppm) community. The mean renal clearance of fluoride and the daily amounts excreted also increased slightly until age fifty, after which a slow decrease was observed. During pregnancy, IPFC decreased significantly until delivery in both fluoridated and non-fluoridated areas. The daily fluoride excretion was also lower during pregnancy than in controls. Patients with renal insufficiency had a mean IPFC of 3.0 + 0.45 umoI/l in the fluoridated and 2. 0 ± 0.14 in the low fluoride community. Their daily fluoride excretion was less than half of that of the control groups. Regularly hemodialyzed patients showed the highest IPFC. In a 6 year-old boy with diabetes insipidus, the IPFC was four times as high as in the corresponding controls. In diabetes mellitus with renal complications, the IPFC was also elevated. Increased water consumption did not cause greater retention of fluoride. In cardiac insufficiency, with normal serum creatinine the IPFC was only slightly elevated.

The relationship between human ionic plasma fluoride and serum creatinine concentrations in cases of renal and cardiac insufficiency in a fluoridated community
Previous studies have shown that renal and cardiac insufficiency cause an elevation of ionic plasma fluoride (IPF) concentration in patients suffering from these diseases. The relationship between serum or plasma fluoride concentration and the degree of renal impairment has been tested only twice; with somewhat contrasting results, although some previous

Association between fluoride exposure and cardiometabolic risk in peripubertal Mexican children.
Highlights Fluoride has been added to table salt in Mexico to reduce dental caries. Human studies of fluoride exposure and metabolic syndrome are rare. We examined the association between fluoride and cardiometabolic risk factors. Fluoride may increase the risk of cardiometabolic disorders in Mexican girls. BACKGROUND: Several animal studies have suggested

Slightly Elevated Serum Ionic Fluoride Levels Inhibit Insulin Secretion and Increase Glucose Levels in a General Japanese Population: a Cross-sectional Study.
A cross-sectional study was performed to investigate the relationships between serum fluoride levels, glucose levels, and insulin secretion in a general population. A total of 330 healthy subjects (167 men; 163 women) aged between 40 and 69 years were examined. Lifestyle information was obtained using questionnaires. Blood samples were collected

Ionic plasma fluoride concentrations related to some diseases in patients from a fluoridated community
Little data is available concerning the relationship between variations in ionic plasma fluoride (IPF) concentrations and some diseases, and that which exists is inconclusive. The effect of renal insufficiency is known best, but the relationship between IPF levels and some oedematous diseases and diabetes has hardly been studied at all

The association of fluoride in drinking water with serum calcium, vitamin D and parathyroid hormone in pregnant women and newborn infants.
Background: Chronic exposure to fluoride in drinking water causes an increase in plasma fluoride levels that is related to a reduction in calcium transport across the renal tubule endoplasmic reticulum and plasma membrane. In the present study, it was hypothesised that varying levels of fluoride present in drinking

Fluoride & Electrocardiogram Abnormalities
An electrocardiogram (ECG) is a diagnostic test that measures the electrical activity of the heart. An ECG can reveal heart rate, heart rhythym (i.e. steady or irregular), and the strength and timing of the heart’s natural electrical signals. ECGs are described in terms of “waves” (e.g. amplitude and duration). Problems

Fluoride & Arterial Calcification
The major change involved with cardiovascular disease is development of atherosclerosis in critical arteries, which is partially characterized by vascular calcification. The level of coronary artery calcification is thought to be the most important indicator of future cardiovascular events. Increased arterial calcifications have frequently been reported in those with skeletal fluorosis

Fluoride & Insulin
Insulin is a hormone produced by the pancreas that is responsible for maintaining appropriate levels of glucose in the blood. Insulin allows the body’s cells to take up glucose from the blood, and either use it as an energy source or store it as glycogen. Blood glucose levels in diabetics

Fluoride, Blood Pressure and Hypertension
Individuals with blood pressure readings that exceed 140/90 are considered hypertensive. Hypertension can increase the risk of stroke, heart attack, heart failure, aortic aneurysms, and peripheral arterial disease. An association between increased fluoride in ground water and increased prevalence of hypertension has been observed, especially among adult males (Amini et
