Fluoride levels of 600 samples of iliac crest bone in ash weight were correlated with age. They showed a near linearship with age. The yearly rate of accumulation of fluoride in bone was found to be 25.589 ug/g bone ash weight. This accumulation rate could be met by the ingestion of 0.867 mg/day of fluoride. The derivation of this figure is indicated and considered in relation to known ranges of dietary and other levels of fluoride ingestion.
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
Predictors of Plasma Fluoride Concentrations in Children and Adolescents.
Despite increasing concerns about neurotoxicity of fluoride in children, sources of fluoride exposure apart from municipal water fluoridation are poorly understood. We aimed to describe the associations of demographics, drinking water characteristics, diet, and oral health behaviors with plasma fluoride concentrations in U.S. children. We used data from 3928 6–19-year-olds
Bone fluoride concentrations associated with fluoridated drinking water
Recently published bone fluoride values from Iowa are very high compared to earlier reports, suggesting an increase in fluoride intake. Reanalysis of the Iowa specimens shows levels one-fourth those reported by the Iowa laboratory indicating an error in the original report. Seventeen bone specimens, collected from long-term residents of Rochester,
Hip fracture incidence not affected by fluoridation. Osteofluorosis studied in Finland
Iliac crest biopsies were taken from patients with hip fracture from a low-fluoride area (less than 0.3 ppm), from an area with fluoridated drinking water (1.0-1.2 ppm), and from a high-fluoride area (greater than 1.5 ppm). Fluoride content analysis and histomorphometry of bone were performed. The hip fracture incidence during
Denser but Not Stronger? Fluoride-Induced Bone Growth and Increased Risk of Hip Fractures.
Abstract Since the mid-1940s, fluoride has been added to toothpaste and (in some countries) tap water, table salt, or milk to reduce dental cavities.1 Although low-level fluoride supplementation prevents cavities, higher levels cause white mottling of the teeth.2 What is more, some studies suggest fluoride in drinking water may increase the
