Abstract
Abstract Novel compositions for establishing environmental conditions in the human oral cavity for maintaining healthy, functional oral leucocytes, said compositions comprising a non-toxic mixture of effective amounts of: (1) at least one compound for maintaining a colloidal and viscous environment within the oral cavity which favors and promotes oral leucocyte locomotion, phagocytosis and bacterial kill; (2) at least one compound providing and maintaining a balanced ionic environment which favors and promotes locomotion, phagocytosis and bacterial kill; (3) at least one compound providing a source of energy for said oral leucocytes; and (4) at least one compound for maintaining substantially a physiological pH to promote leucocyte functions while avoiding other tissue and cell injury; and novel products and processes employing the same.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
150 words
A composition for establishing environmental conditions in the human oral cavity for maintaining healthy functional oral leucocytes, said composition comprising a non-toxic mixture of effective amounts of: (1) at least one compound selected from the group consisting of dextran, cellulose ethers, polyvinylpyrrolidone and gelatin for maintaining a colloidal and viscous environment within the oral cavity which favors and promotes oral leucocyte locomotion, phagocytosis and bacterial kill; (2) at least one compound selected from the group consisting of carbohydrates, fats and proteins to provide a source of energy for said oral leucocytes; (3) an inorganic salt providing and maintaining a balanced ionic environment which favors and promotes locomotion, phagocytosis and bacterial kill; and (4) at least one compound selected from the group consisting of phosphate buffers, carbon dioxide-bicarbonate buffers, tris buffers and glycylglycine buffers for maintaining substantially a physiological pH to promote leucocyte functions while avoiding other tissue and cell injury.
Claim 2
Dependent Claim
150 words
A composition for establishing environmental conditions in the human oral cavity for maintaining healthy functional oral leucocytes, said composition comprising a non-toxic mixture of effective amounts of: (1) at least one compound selected from the group consisting of dextran, cellulose ethers, polyvinylpyrrolidone and gelatin for maintaining a colloidal and viscous environment within the oral cavity which favors and promotes oral leucocyte locomotion, phagocytosis and bacterial kill; (2) at least one compound selected from the group consisting of carbohydrates, fats and proteins to provide a source of energy for said oral leucocytes; (3) an inorganic salt providing and maintaining a balanced ionic environment which favors and promotes locomotion, phagocytosis and bacterial kill; and (4) at least one compound selected from the group consisting of phosphate buffers, carbon dioxide-bicarbonate buffers, tris buffers and glycylglycine buffers for maintaining substantially a physiological pH to promote leucocyte functions while avoiding other tissue and cell injury.
Claim 3
Dependent Claim
17 words
A composition as defined in claim 1 wherein said pH is from about 5.5 to about 9.
Claim 4
Dependent Claim
31 words
A composition as defined in claim 1 including at least one additional reagent selected from the group consisting of anti-caries agents, flavoring agents, effervescing agents, preservatives, colorants, viscous reagents and solvents.
Claim 5
Dependent Claim
62 words
A composition as defined in claim 1 wherein said first mentioned compound is present in an amount of from 0.5 to 10.0 parts by weight; said second mentioned compound in from 0.1 to 3.0 parts by weight; said third mentioned compound in from 0.26 to 5.2 parts by weight; and said last mentioned compound in from 0.015 to 1.5 parts by weight.
Claim 6
Dependent Claim
13 words
A solution, toothpaste or powder comprising a composition as defined in claim 1.
Claim 7
Dependent Claim
70 words
A composition as defined in claim 4 wherein said compound providing a colloidal and viscous environment is dextran; said compound providing a source of energy is glucose; said balanced ionic environment is provided by a mixture of compounds comprising sodium chloride, sodium bicarbonate, calcium chloride, potassium chloride, monopotassium dihydrogen phosphate and magnesium sulfate; and said physiological pH is provided by the interaction of sodium bicarbonate and tartaric or citric acid.
Claim 8
Dependent Claim
13 words
A process which comprises applying orally a composition as defined in claim 1.
Claim 9
Dependent Claim
21 words
A process as defined in claim 7 wherein said composition is applied as a solution, slurry, powder or as a toothpaste.
Claim 10
Dependent Claim
45 words
A composition as defined in claim 1 including at least one compound selected from the group consisting of heparin, chondroitin sulfate and polyanionic polysaccharides to provide a negative charge potential whereby to reduce clustering of leucocytes and to eliminate agglutination and precipitation of protoplasmic particles.
