METHOD AND DEVICE FOR ELECTROCHEMICAL TEETH WHITENING Russian patent published in 2012 - IPC A61K8/22 A61K8/38 A61Q11/02 A61C17/16 

FIELD: medicine.

SUBSTANCE: invention is referred to the method of electrochemical teeth whitening which consists of putting on the teeth first the solution of salt of transition metal and then oxidizing agent while limiting the effect of metal salts and oxidizing agent on non-dental oral tissues. After that positive and negative electrodes are configured in oral cavity in such a way that negatively charged electrodes contact with teeth and electric current is sent only in oral cavity to said oxidizing agent for its activation and reduction. Oxidizing agent contains hydrogen peroxide, solution or gel of carbamide peroxide or sodium perborate. The invention is also referred to teeth whitening device that contains applicator suitable for putting salt of transition metal and oxidizing agent on teeth. Applicator is made in shape of dental tray and has first and second ends to which the electrodes are connected with the possibility of sending electric current through the applicator as well as sealing bulge for limiting the oxidizing agent effect on non-dental oral tissue. The group of inventions provides for regulation of safe application, supply and distribution on teeth of oxidizing agent.

EFFECT: simple and safe method of teeth whitening; minimal effect of oxidizing agent on non-dental oral tissue.
