Abstract
The present invention provides a device for fluoride iontophoresis, comprising at least one electrochemical cell device containing at least one electrode and a fluoride-containing electrolyte, wherein the electrode is operated via an electromotive force to drive the fluoride-containing electrolyte into a biological interface; and a power supply connecting electrically to the cell device and at least providing a periodic pulse voltage signal to the electrode.
Claims6
A method for importing fluoride ions into a tooth comprising steps of:
- applying a fluoride iontophoresis device comprising an electrochemical cell device including at least one electrode and a fluoride-containing electrolyte, and a power supply connecting electrically to the electrochemical cell device;
- wherein at least one electrode contacts with the tooth;
- and
- providing an electromotive force by the power supply to the electrode to drive the fluoride-containing electrolyte into the tooth;
- and
- the method is characterized that the power supply provides a periodic pulse voltage to the electrode, wherein the periodic pulse voltage comprises a base potential and a pulse potential, the base potential and the pulse potential being variable over different periods, the base potential being gradually changed to reach the pulse potential with a plurality of steps in each period.
