Abstract
Abstract An oral electrical treatment apparatus and method that includes contacting gingival tissue around a plurality of teeth with electrical contact members, providing means for supplying an electrical current to the electrical contact and providing means for adjusting the electrical current supplied to the electrical gingival contact members. The oral electrical treatment apparatus and method also includes means for monitoring the current received by the gingival tissue from the electrical gingival contact members. The oral electrical treatment apparatus and method permits defects and diseases in the mouth to be conveniently treated with a minimal amount of discomfort to the patient.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
108 words
Oral electrical treatment apparatus comprising means for electrically contacting gingival tissue in a mouth, said gingival electrical contacting means comprising at least one electrode assembly including at least two elongated gingival tissue contact members each having an underside shaped to conform to the shape of the gingival tissue adjacent a tooth in said mouth, said gingival tissue contact members each having an inner surface shaped to conform to the exterior outer surface of said tooth just above the gum line, means locatable about said tooth for locating said electrode assembly, and means locatable outside of said mouth for supplying an electrical current to said gingival electrical contacting means.
Claim 2
Dependent Claim
108 words
Oral electrical treatment apparatus comprising means for electrically contacting gingival tissue in a mouth, said gingival electrical contacting means comprising at least one electrode assembly including at least two elongated gingival tissue contact members each having an underside shaped to conform to the shape of the gingival tissue adjacent a tooth in said mouth, said gingival tissue contact members each having an inner surface shaped to conform to the exterior outer surface of said tooth just above the gum line, means locatable about said tooth for locating said electrode assembly, and means locatable outside of said mouth for supplying an electrical current to said gingival electrical contacting means.
Claim 3
Dependent Claim
14 words
The oral electrical treatment apparatus of claim 1 comprising a plurality of electrode assemblies.
Claim 4
Dependent Claim
44 words
The oral electrical treatment apparatus of claim 1 wherein said elongated gingival contact members have a length sufficient to surround substantially 70 to 85 percent of one half of the exterior surface of said tooth when said elongated gingival contact members are in place.
Claim 5
Dependent Claim
29 words
The oral electrical treatment apparatus of claim 3 wherein at least a portion of said elongated gingival contact members have a width between about one to about two millimeters.
Claim 6
Dependent Claim
24 words
The oral electrical treatment apparatus of claim 3 wherein said means locatable about said tooth for locating said electrode assembly comprises a clip member.
Claim 7
Dependent Claim
20 words
The oral electrical treatment apparatus of claim 5 wherein said clip member comprises an elongated bent piece of spring material.
Claim 8
Dependent Claim
27 words
The oral electrical treatment apparatus of claim 6 wherein said clip member is sized and shaped to exert an inward pressure on said elongated gingival contact members.
Claim 9
Dependent Claim
20 words
The oral electrical treatment apparatus of claim 7 wherein said clip member is bent generally into a horse shoe configuration.
Claim 10
Dependent Claim
25 words
The oral electrical treatment apparatus of claim 7 wherein said means for supplying an electrical current also includes means for varying the output current therefrom.
Claim 11
Dependent Claim
26 words
The oral electrical treatment apparatus of claim 9 further comprising means for monitoring the electrical current received by the gingival tissue from said electrical contacting means.
Claim 12
Independent Claim
154 words
A method of treating disease or defects in the mouth having teeth comprising: providing a plurality of electrical contacts for contacting gingival tissue in said mouth, said electrical contacts having an inner surface conforming to the surface of a tooth just above the gum line and having lower portions conforming to the gingival tissue located adjacent to the tooth; means for locating and exerting a pressure on said electrical contacts to contact gingival tissue around a tooth in said mouth; and means for supplying an electrical current to said plurality of electrical contacts; placing said locating and pressure exerting means and electrical contacts in said mouth with the contacts surrounding a substantial portion of a tooth to cause said electrical contacts to contact said gingival tissue surrounding said tooth and activating said means for supplying an electrical current to supply electrical current to said electrical contacts and to said gingival tissue surrounding said tooth.
Claim 13
Independent Claim
154 words
A method of treating disease or defects in the mouth having teeth comprising: providing a plurality of electrical contacts for contacting gingival tissue in said mouth, said electrical contacts having an inner surface conforming to the surface of a tooth just above the gum line and having lower portions conforming to the gingival tissue located adjacent to the tooth; means for locating and exerting a pressure on said electrical contacts to contact gingival tissue around a tooth in said mouth; and means for supplying an electrical current to said plurality of electrical contacts; placing said locating and pressure exerting means and electrical contacts in said mouth with the contacts surrounding a substantial portion of a tooth to cause said electrical contacts to contact said gingival tissue surrounding said tooth and activating said means for supplying an electrical current to supply electrical current to said electrical contacts and to said gingival tissue surrounding said tooth.
Claim 14
Dependent Claim
37 words
The method of claim 11 further comprising supplying means for adjusting the electrical current supplied by said electrical current supply means and using said adjusting means to adjust the current supplied by said electrical current supplying means.
Claim 15
Dependent Claim
38 words
The method of claim 12 further comprising providing means for monitoring the electrical current to the gingival tissue through said electrical contacts and using said electrical current monitoring means for monitoring the current supplied to said gingival tissue.
Claim 16
Dependent Claim
29 words
The method of claim 12 wherein said step of supplying an electrical current to said electrical contacts comprises supplying a current between about five microamperes and about twenty microamperes.
Claim 17
Dependent Claim
25 words
The method of claim 14 wherein the step of supplying an electrical current to said electrical contacts comprises supplying a current of about fifteen microamperes.
Claim 18
Dependent Claim
33 words
The method of claim 12 wherein said step of activating said means for supplying an electrical current comprises supplying electric current for a period of time from about eight to about twenty-five minutes.
Claim 19
Dependent Claim
31 words
The method of claim 16 wherein said step of activating said means for supplying an electrical current comprises supplying an electrical current for a period of time of about twenty minutes.
