Abstract
Serum and urine fluoride levels were determined in 250 healthy subjects (15-90 years, 122 men and 128 women) residing in Catalonia, Spain, and in 150 patients (20-81 years, 84 men and 66 women) with chronic renal failure undergoing regular dialysis treatment, living in the same geographical area, to determine normal range and to investigate its relationships to age, sex and renal function. Serum and urine fluoride were determined by a fluoride ion specific electrode system. Mean (+/- S.D.) serum fluoride concentration was 17.5 +/- 9.5 micrograms/l, ranging from 1 to 47 micrograms/l, in the control group and 58 +/- 31 micrograms/l, ranging from 28 to 185 micrograms/l, in renal patients. Urine fluoride concentration in the healthy group was 671 +/- 373 micrograms/24 h, ranging from 156 to 1900 micrograms/24 h. Fluoride status in the patient group was significantly greater than the control group. There was significant correlation between serum fluoride and age. No sex related difference was found.

Serum ionic fluoride concentrations are related to renal function and menopause status but not to age in a Japanese general population
BACKGROUND: There have been no studies in which fasting serum ionic fluoride (SIF) concentrations in a general population were investigated despite the fact that SIF has various activities in humans. METHODS: A total of 332 healthy subjects (167 men and 165 women aged 40 to 69years) were selected from residents of

Renal osteodystrophy in patients on long-term hemodialysis with fluoridated water
Serum and bone fluoride concentrations of ten patients maintained on long-term hemodialysis with fluoridated water (1 ppm, i.e., 50uM) were correlated with duration of treatment and the occurrence of clinical, radiological, and histological manifestations of bone disease. Two patients had symptomatic renal osteodystrophy when accepted on the program, whereas six

Plasma and water fluoride levels and hyperuricemia among adolescents: A cross-sectional study of a nationally representative sample of the United States for 2013–2016.
Highlights Relatively low levels of fluoride exposure in US adolescents but with wide ranges. Dose-dependent increase in prevalence of hyperuricemia with increasing fluoride levels. Significant associations between plasma and water fluoride and hyperuricemia. A positive relationship between water and plasma fluoride concentrations. Potential role of chronic fluoride exposure in

Environmental Fluoride 1977 by Rose & Marier
The Associate Committee on Scientific Criteria for Environmental Quality was established by the National Research Council of Canada in response to a mandate provided by the Federal Government to develop scientific guidelines for defining the quality of the environment. The concern of the NRC Associate Committee is strictly with scientific

Fluoride exposure and kidney and liver function among adolescents in the United States: NHANES, 2013–2016.
Highlights Plasma fluoride concentrations are associated with kidney and liver parameters among United States (U.S.) adolescents Higher water fluoride concentrations are associated with lower blood urea nitrogen among U.S. adolescents Fluoride exposure may contribute to complex changes in kidney and liver related parameters among U.S. adolescents Altered kidney and/or liver

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, Dialysis & Osteomalacia
In the 1960s and 1970s, doctors discovered that patients receiving kidney dialysis were accumulating very high levels of fluoride in their bones and blood, and that this exposure was associated with severe forms of osteomalacia, a bone-softening disease that leads to weak bones and often excruciating bone pain. Based on

Fluoride & Osteomalacia
One of fluoride's most well-defined effects on bone tissue is it's ability to increase the osteoid content of bone. Osteoid is unmineralized bone tissue. When bones have too much of it, they become soft and prone to fracture -- a condition known as osteomalacia. As shown below, fluoride has repeatedly been

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.

Dental Fluorosis & Enamel Hypoplasia in Children with Kidney Disease
Children with kidney disease are known to have high levels of fluoride in their blood and to be at risk for disfiguring tooth defects. Research suggests that high levels of fluoride in blood, which can cause the tooth defect known as dental fluorosis, can contribute to the defects that occur
