ABSTRACT:
A disposable finger applicator adapted to facilitate the application of a two-component therapeutic agent to gum tissues for treating periodontal disease. The applicator includes a collapsible thimble which when in use fits on the index finger of the user, the thimble being bonded to the rear wall of a small envelope formed of opaque, non-stretchable film material containing a charge of hydrogen peroxide in an aqueous solution. Marginally secured to the front wall of the envelope and otherwise spaced therefrom to define an internal cavity is an outer layer of porous, sponge-like material, the cavity being filled with dry sodium bicarbonate powder. The front wall of the envelope is provided with a weakened zone, such that when the finger applicator is pressed by the user against gum tissue, the hydrogen peroxide solution trapped in the envelope then ruptures the weakened zone, thereby causing the solution to leak into the cavity and to intermingle with the sodium bicarbonate powder. The resultant slurry impregnates the outer layer and is extruded therefrom as the applicator is rubbed along the gums to therapeutically treat the tissues thereof and to at the same time stimulate the tissues.
