[Significance of fluorides in chronic hemodialysis with reference to fluoridation of drinking water].

The metabolism of fluorides in impaired renal function is described. The use of fluoridized drinking-water in the production of dialysis fluid is discussed controversial. In patients treated by chronic hemodialysis the plasma fluoride level rises at a content of 1 mg fluoride per liter dialysis fluid. A relevant effect on the state of health is not certain established today. Therefore, it will be advised to the use of fluoride-free dialysis water. Its production should be made by use of a reverse-osmosis unit.
