Complete fluoride intake data from the 2000-2003 UK National Diet and Nutrition Survey were used to examine questions outstanding from the Fluoridation of Water Supplies review process. In a quarter of the population, fluoride consumption from all sources exceeds the Safe Intake defined by the Committee on the Medical Aspects of Food Policy, regardless of water fluoride concentration. In areas supplied with fully fluoridated water, fluoride intake exceeds the recommended safe maximum in nearly two thirds of consumers. The implications are discussed and recommendations are made.
Elevated levels of arsenic and fluoride, but not selenium, associated with endemic disease in the Chinese village of Dazhuyuan, Shaanxi province.
In this investigation, we determined the concentrations of arsenic (As), fluoride (F), and selenium (Se) in the environment (coal, drinking water, soil, corn, and chili) and in biological samples from local residents (urine, hair, and serum) from the endemic disease village of Dazhuyuan and the non-endemic disease control village of
Biomarkers for the Assessment of Fluoride Exposure in Children.
Due to practical difficulties in quantifying fluoride exposure, the ability of various biomarkers to predict exposure has been investigated previously. However, the results are inadequate for validation of their application and usefulness. This study aimed to investigate the association between contemporary/recent biomarkers of fluoride exposure and total daily fluoride intake
Total fluoride intake and excretion in children up to 4 years of age living in fluoridated and non-fluoridated areas.
Fractional fluoride retention is important during the early years of life when considering the risk of development of dental fluorosis. This study aimed to measure fractional fluoride retention in young children. The objectives were to investigate the relationships between fractional fluoride retention and total daily fluoride intake, age, and body
Effects of water improvement and defluoridation on fluorosis-endemic areas in China: A meta-analysis.
Highlights The first analysis of the effect of improving water quality and reducing fluoride in China over 40 years. Analysis of the effect of water improvement and fluoride reduction in different provinces of China. We analyzed the effect of water improvement on dental fluorosis, skeletal fluorosis, and fluoride content
Monitoring salt fluoridation programs through urinary excretion studies.
This paper reviews problems associated with urinary collection for the estimation of fluoride exposure and recent findings in this context. After intake of a salted meal at noon, children aged 9 to 14 excreted on average 45 microgF/h. Morning and nocturnal excretions were only 16 microgF/h with the exception of
