Abstract
The influence of fluoride in drinking water on stone formation was studied in animals and in “in vitro” crystallization experiments. In male Wistar rats fluoride inhibits ethylenglycol induced calcification of the kidneys and stone formation. The in vitro results performed in synthetic urine exhibited a dose-dependent delay of crystal growth.

Correlative study of fluoride content in urine, serum and urinary calculi
Fluoride content was measured in 100 urinary stones retrieved by open surgery of stone formers admitted at PGIMS Rohtak and their respective urine and serum and compared with those of healthy individuals. The concentration of fluoride was also measured in the sources of drinking water of these stone formers. The

Evidence suggesting that high intake of fluoride provokes nephrolithiasis in tribal populations.
The present study was designed to evaluate the role of fluoride in urolithiasis in humans. Two areas were selected for this purpose, a fluoride endemic area (EA) and a fluoride non-endemic area (NEA). The prevalence of uroliathiasis was 4.6 times higher in EA than in NEA. Furthermore, the prevalence was

Medical aspects of excessive fluoride in a water supply
A 10-year study of 116 persons in Bartlett and 121 in Cameron, Tex., was conducted to determine if prolonged exposure to fluoride in the water supply of Bartlett had produced detectable physiological effects. Bartlett's water contained about 8 p.p.m. F until 1952, when an experimental defluoridation unit was installed, reducing the

Role of fluoride in formation of urinary calculi: studies in rats
The effect of fluoride on urinary calculi formation in young rats was investigated. Two studies, in which rats received diets that included either higher calcium (9 g/kg diet) or normal calcium (5 g/kg diet), were conducted At each level of calcium, one group of rats received a high level of

Association between Fluoride Concentration in Public Water Supplies and Beneficial and Adverse Health Outcomes in England: An Ecological Study.
The following abstract was presented by co-author Tony Fletcher at the August 2018 Annual Conference of the International Society for Environmental Epidemiology (ISEE) in Ottawa, Canada. The protective effect of community water fluoridation (CWF) on caries is established, but secular changes may modify its impact. Relationships with adverse health outcomes have
