Patent ID: 7775795

Claim:
A kit for dental treatment, the kit comprising an electrochemical device, a substance, and an activating solution: a) said device comprising an applicator for applying a substance to a tooth, said applicator forming a dental tray having a back curved wall and a front curved wall, defining therebetween a teeth receiving channel; a spacer connected to said back curved wall of said applicator; a first electrode attached to said back curved wall of said applicator, said first electrode connected to said spacer to preclude a contact of said first electrode with teeth; a second electrode attached to said front curved wall of said applicator, said second electrode being extending from said front curved wall so that said electrode would be in direct contact with teeth when said applicator is worn; a sealing lip connected to said back curved wall and said front curved wall, operative to substantially prevent leaking out of substance or activation solution; wherein said first electrode and said second electrode are configured to produce a current flow through said applicator but not through a non-intra-oral cavity body part, both electrodes being positioned inside said tray; and wherein said sealing lip minimizes exposure of non-intra-oral cavity body parts to said substance; b) said substance being an ionizable substance placed within said applicator and undergoing ionization upon application of said current flow, wherein the tooth surface absorbs the ionizable substance, said absorption improved by first applying said activating solution to the tooth; c) said activating solution being a metal salt solution which may be applied to a tooth before said ionization to enhance the absorption of said ionizable substance.
