Abstract
Urinary tract calculi obtained from 25 patients residing in an endemic fluorotic area revealed a significantly higher fluoride content compared to calculi from 25 persons from a nonendemic area. However the difference in their calcium and phosphate content was not significant. Twenty-four hour urinary fluoride excretion was significantly higher in 10 fluorotic patients than in 10 controls. The incidence of urinary tract calculi was elevated in most of the fluorotic districts of Punjab.

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

Effect of fluoride, silicon, and magnesium on the mineralizing capacity of an inorganic medium and stone formers urine tested by a modified in vitro method.
An in vitro mineralizing system using bovine achilles tendon developed by Thomas and Tomita (3) was modified to enable quantitative evaluation of mineralization. Using this modified method, the potential effect of various ions on the rate of calcium uptake from inorganic mineralization medium was measured. Of the elements tested, only

Recovery from skeletal fluorosis (an enigmatic, American case)
A 52-year-old man presented with severe neck immobility and radiographic osteosclerosis. Elevated fluoride levels in serum, urine, and iliac crest bone revealed skeletal fluorosis. Nearly a decade of detailed follow-up documented considerable correction of the disorder after removal of the putative source of fluoride (toothpaste). INTRODUCTION: Skeletal fluorosis, a crippling bone

Determination of fluoride ions in urinary stones by ion chromatography.
A method of the ion chromatographic determination of fluoride ions in urinary stones has been developed. Sample preparation of solid mineral-organic samples includes dissolution in concentrated hydrochloric acid, dilution with deionized water, and the elimination of excess calcium and magnesium cations by adding a KU-2 sulfo cation exchanger in the

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
