Abstract
Abstract This invention relates to a method of relieving gum discomfort in children and endentulous persons comprising applying to the gums an ingestible, non foaming, oral hygiene gel that cleans, massages and conditions gums and removes the "plaque-like" film that forms on gums while disrupting the subsequent formation of plaque-like film on said gums.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
66 words
A method for relieving the discomfort associated with teething in babies and the wearing of dentures by endentulous persons comprising; applying to said gums an oral hygiene gel suitable for cleaning, massaging and conditioning gums, wherein: A. said gel is free from: 1. abrasives, 2. analgesics, and 3. substances that alter the microflora balance of the oral cavity; and wherein B. said gel consists essentially of:
Claim 2
Independent Claim
66 words
A method for relieving the discomfort associated with teething in babies and the wearing of dentures by endentulous persons comprising; applying to said gums an oral hygiene gel suitable for cleaning, massaging and conditioning gums, wherein: A. said gel is free from: 1. abrasives, 2. analgesics, and 3. substances that alter the microflora balance of the oral cavity; and wherein B. said gel consists essentially of:
Claim 3
Dependent Claim
87 words
a nonionic surfactant, 2. a coating substance insoluble in said surfactant, wherein the weight ratio of said nonionic surfactant to said coating substances is from between about 50.1 and 1:1; and 3. a viscosifier; and C. said gel is characterized as being: 1. stable, 2. ingestible, 3. non-foaming, 4. substantive to the gums of babies and endentulous persons, 5. disruptive towards the formation of plaque-like films on the gums of babies and endentulous persons; and having 6. a pH of from between about 3 and about 10.
Claim 4
Dependent Claim
87 words
a nonionic surfactant, 2. a coating substance insoluble in said surfactant, wherein the weight ratio of said nonionic surfactant to said coating substances is from between about 50.1 and 1:1; and 3. a viscosifier; and C. said gel is characterized as being: 1. stable, 2. ingestible, 3. non-foaming, 4. substantive to the gums of babies and endentulous persons, 5. disruptive towards the formation of plaque-like films on the gums of babies and endentulous persons; and having 6. a pH of from between about 3 and about 10.
Claim 5
Dependent Claim
18 words
The method of claim 1, wherein said gel is applied to the gums by a gauze covered finger.
Claim 6
Dependent Claim
18 words
The method of claim 1, wherein said gel is applied to the gums by a soft bristled brush.
Claim 7
Dependent Claim
21 words
The method of claim 1, wherein the nonionic surfactant in the gel is selected from block copolymer mixtures of polyoxyalkylene compounds.
Claim 8
Dependent Claim
16 words
The method of claim 4, wherein said block copolymers are mixtures of polyoxypropylene and polyoxethylene compounds.
Claim 9
Dependent Claim
24 words
The method of claim 1, wherein the coating substance in the gel is selected from the group consisting of silicones, polyalkylsiloxanes and mixtures thereof.
Claim 10
Dependent Claim
10 words
The method of claim 6, wherein the polyalkylsiloxanes are polydimethylsioxanes.
Claim 11
Dependent Claim
27 words
The method of claim 1, wherein the viscosifier in the gel is selected from the group of cellulose ethers consisting of sodium carboxymethylcellulose, hydroxypropylcellulose, and mixtures thereof.
Claim 12
Dependent Claim
38 words
The method of claim 1, wherein the pH of the gel is from between about 4.0 and about 8.5, and the weight ratio of nonionic surfactant to coating composition therein is from between about 20:1 and about 2:1.
Claim 13
Dependent Claim
24 words
The method of claim 1, wherein the concentration of nonionic surfactant in the gel is from between about 0.1% and about 10% by weight.
Claim 14
Dependent Claim
24 words
The method of claim 7, wherein the concentration of coating substance in the gel is from between about 0.1% and about 0.5% by weight.
Claim 15
Dependent Claim
23 words
The method of claim 8, wherein the concentration of viscosifier in the gel is from between about 0.5% and about 10% by weight.
Claim 16
Dependent Claim
50 words
The method of claim 1, wherein the surfactant in the gel is a poloxamer of ethylene oxide and propylene oxide at about 2% by weight, the coating substance in the gel is a polydimethylsiloxane at about 0.12% by weight and the viscosifier therein is carboxymethylcellulose at about 2.5% by weight.
