Abstract
Abstract A toothbrush for increasing the concentration of fluoride ions in micro-porous openings in the teeth when fluoride toothpaste is brushed onto the teeth in the mouth. The toothbrush includes at least one magnet in contact with dialectric material, a conductor in contact with the magnet, and conductive bristles in contact with the conductor. The dialectric material, the conductor and the conductive bristles together comprise means for rapidly diffusing fluoride ions in the mouth when fluoride toothpaste is brushed on the teeth by the bristles.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
101 words
A toothbrush for increasing the concentration of fluoride ions in predetermined portions of the teeth when fluoride toothpaste is brushed onto the teeth in the mouth, wherein said toothbrush comprises: (a) a dielectric material; (b) at least one magnet in contact with said dielectric material; (c) a conductor in contact with said at least one magnet; and (d) conductive bristles in contact with said conductor, wherein said dielectric material, said magnet, said conductor and said conductive bristles together comprise a means for rapidly diffusing said fluoride ions in the mouth when fluoride toothpaste is brushed on said teeth by said bristles.
Claim 2
Dependent Claim
101 words
A toothbrush for increasing the concentration of fluoride ions in predetermined portions of the teeth when fluoride toothpaste is brushed onto the teeth in the mouth, wherein said toothbrush comprises: (a) a dielectric material; (b) at least one magnet in contact with said dielectric material; (c) a conductor in contact with said at least one magnet; and (d) conductive bristles in contact with said conductor, wherein said dielectric material, said magnet, said conductor and said conductive bristles together comprise a means for rapidly diffusing said fluoride ions in the mouth when fluoride toothpaste is brushed on said teeth by said bristles.
Claim 3
Dependent Claim
16 words
The toothbrush defined by claim 1 wherein said conductive brush is composed of magnetic synthetic resin.
Claim 4
Dependent Claim
67 words
The toothbrush defined by claim 1 wherein said toothbrush further comprises: (e) a head; and (f) a handle, wherein said at least one magnet is positioned in said head and wherein said handle and head each have a bottom portion and wherein said conductor is located on said bottom portion of said handle and head, and wherein said conductor is a thermal conductor and conducts static electricity.
Claim 5
Dependent Claim
52 words
The toothbrush defined by claim 3 wherein said handle and head each have a top portion and wherein said dielectric material is located on said top portion of said handle and head, and wherein said at least one magnet is disposed between said top portion and said bottom portion of said head.
Claim 6
Dependent Claim
23 words
The toothbrush defined by claim 4 wherein said at least one magnet comprises two magnetic surfaces separated by a magnetically neutral zone therebetween.
Claim 7
Dependent Claim
12 words
The toothbrush defined by claim 1 wherein said toothbrush comprises two magnets.
Claim 8
Dependent Claim
11 words
The toothbrush defined by claim 1 wherein said conductor is magnetic.
Claim 9
Dependent Claim
31 words
The toothbrush defined by claim 7 wherein said at least one magnet has surfaces which comprise means for emitting a magnetic field, wherein said emitting surfaces are covered by said conductor.
Claim 10
Dependent Claim
38 words
The toothbrush defined by claim 1 wherein said toothbrush is adapted to brush teeth with a fluoride toothpaste having active ingredients and wherein said diffusing means comprises a polarizing means for polarizing said active ingredients of said toothpaste.
Claim 11
Dependent Claim
58 words
The toothbrush defined by claim 9 wherein said toothbrush has an emitting surface for emitting a magnetic field and wherein each tooth has a receiving surface, and wherein said polarizing means comprises means for ionizing and polarizing said emitting and receiving surfaces and for ionizing and polarizing said active ingredients of said toothpaste used for cleaning said teeth.
Claim 12
Dependent Claim
45 words
The toothbrush defined by claim 10 wherein said ionizing and polarizing means comprises a means for subjecting said teeth, said fluoride toothpaste and said toothbrush to the combination of hydrodynamic action, a magnetic field, a static electric field, and the electrothermal effects of human heat.
