Abstract
Transplacental passage of fluorides was studied in 25 randomly selected neonates. Blood samples collected simultaneously from the mother and the umbilical cord showed that average fluoride concentration in the cord blood was 60% of that in mother’s blood. When concentration in the mother’s blood exceeded 0.4 ppm, the placenta acted as a selective barrier.

Studies on fluorosis in Mehsana District of North Gujarat.
A survey was conducted in eighteen fluoride endemic villages in Mehsana District of North Gujarat (India). The individuals afflicted with fluorosis were examined for apparent mottled teeth and skeletal complications. Samples of urine and blood of these individuals along with drinking water were collected and compared with samples obtained from

Placental transfer of fluoride in pregnant women consuming optimum fluoride in drinking water.
The study was conducted on 25 healthy women residing in optimum fluoride areas, who were to deliver normally through vaginal route, to correlate the maternal and cord plasma fluoride levels and evaluate the placental transfer of fluoride. A wide variation was found in the maternal and cord plasma fluoride levels.

Biochemistry of Fluorosis X - Comparative Study of the Fluoride Levels in Biological Fluids.
The fluoride content of drinking water is directly correlated with the serum and saliva fluoride. Serum fluoride levels are also directly related to those of saliva, but not to urinary fluoride. These interrelations are so close that a mathematical formula can be devised for the calculation of fluoride in body fluids.

The Influence of fluoride on chronic kidney disease of uncertain aetiology (CKDu) in Sri Lanka.
Fluoride is an element that is widely distributed in the environment. The involvement of fluoride in pathogenesis of Chronic Kidney Disease of uncertain aetiology (CKDu) in Sri Lanka is a much-debated topic. This study aimed to investigate the fluoride concentration in drinking water in CKDu affected areas in Sri Lanka

Effects of fluoride on bone metabolism in patients with hemodialysis
The maior pathway of fluoride elimination from the human body is the kidney. The discharge of fluoride into urine depends on the clearance of the kidney. Fluoride in serum of hemodialysis patients is higher than that of healthy subjects. Fluoride is not reduced sufficiently with hemodialysis. Those patients are in
