Abstract
Industries that use fluoride-containing materials are usually aware of their toxicity and adopt adequate medical measures. It has been found that workers in factories who have not been considered as subjected to fluorine hazard and therefore have not been controlled had significantly elevated urinary fluoride levels. Most workers in a medically controlled fertilizer plant had normal urinary levels. Maintenance workers were found to have higher values, up to 12 mg/liter.

Prevention of bony fluorosis in aluminum smelter workers. A 15-year retrospective study of fluoride excretion and bony radiopacity among aluminum smelter workers -- Pt. 4
1. Fifty six aluminum smelter workers with 10 to 43 years' occupational exposure, and who had been previously studied medically, were re-x-rayed. Average urinary fluoride concentrations since 1960 were estimated to range from 2.78 mg/liter preshift and 7.71 mg/liter postshift. 2. Roentgenographic studies in 1960-66 and 1974 failed to reveal

Renal clearance of fluoride in children and adolescents
Renal function and fluoride excretion have been studied in 38 children. The children were divided into three groups according to their glomerular filtration rate: normal (92 to 136 mL/min/1.73 m2 of body surface area [BSA]), low (less than 92 mL/min/1.73 m2 BSA, and super-normal (greater than 136 mL/min/1.73 m2 BSA).

Fluoride, Thyroid Hormone Derangements and its Correlation with Tooth Eruption Pattern Among the Pediatric Population from Endemic and Non-endemic Fluorosis Areas.
AIM: To comparatively evaluate the status of fluoride in the body with thyroid activity in the pediatric population of endemic fluorosis areas. The present study also attempted to elucidate whether any correlation exists between fluoride and thyroid hormone derangement with delayed tooth eruption. MATERIALS AND METHODS: A total of 400 pediatric

Systematic review of epidemiological and toxicological evidence on health effects of fluoride in drinking water.
Introduction Fluoride is a naturally occurring substance that is also added to drinking water, dental hygiene products, and food supplements for preventing dental caries. Concerns have been raised about several other potential health risks of fluoride. Objective To conduct a robust synthesis of evidence regarding human health risks due to exposure to fluoride

Trimester Specific Association of Prenatal Fluoride Exposure and Cognitive Outcomes in Children in Mexico.
Background: There is increasing evidence suggesting that prenatal exposure to fluoride is associated with lower neurocognitive performance in offspring. The objective of this study is defining periods in early life associated with greater sensitivity to fluoride exposures. METHODS: This study focused on participants from the Early Life Exposures in Mexico to
