Device for cleaning tooth and gum surfaces
The invention provides, a device for cleaning tooth and gum surfaces the device having incorporated therein an antimicrobial polymeric material formed from a polymeric component, the material being in the form of a bristle or yam, and comprising an antimicrobial agent consisting essentially of discreet, microscopic, Cu ++ releasing water insoluble particles, embedded directly in the component, with a portion of the particles being exposed and protruding from surfaces thereof, which particles release Cu ++ ions, upon contact with a fluid.
1 . A device for cleaning tooth and gum surfaces said device having incorporated therein an antimicrobial polymeric material formed from a polymeric component, said material being in the form of a bristle or yarn, and comprising an antimicrobial agent consisting essentially of discreet, microscopic, Cu ++ releasing water insoluble particles, embedded directly in said component, with a portion of said particles being exposed and protruding from surfaces thereof, which particles release Cu ++ ions, upon contact with a fluid.
2 . A device for cleaning tooth and gum surfaces according to claim 1 , wherein said polymeric material has incorporated therein exposed Cu ++ releasing water insoluble copper oxide particles which protrude from the polymeric material.
3 . A device for cleaning tooth and gum surfaces according to claim 1 , wherein said polymeric material has incorporated therein a mixture of particles of CuO and Cu 2 O which particles release combinations of Cu ++ and Cu + upon contact with a fluid.
4 . A device for cleaning tooth and gum surfaces according to claim 1 , wherein said particles are of a size of between 1 and 10 microns.
5 . A device for cleaning tooth and gum surfaces according to claim 1 wherein said particles are present in an amount of between 0.25 and 10% of the polymer weight.
