Abstract
Abstract The method of treating teeth for the removal of dental plaque and/or dental calculus from said teeth, and the prevention of the formation thereof thereon. The method involves contacting the teeth with a sufficient and effective amount to achieve such purpose of a mouthwash. The mouthwash is a liquefied composition of an effective amount of a non-necrotic fatty acid compound prepared from an unsubstituted, unsaturated fatty acid having at least one double bond, a liquid carrier, an effective amount of a buffering agent and an effective amount of ethanol. The pH of the liquefied composition is between 8 and 11. The preferred mouthwash contains about 5 percent of sodium oleate, about 1.5 percent of ethanol, enough disodium hydrogen phosphate to adjust the pH to about 9.8 and the remainder water.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
81 words
The method of treating teeth for the removal of dental plaque and/or dental calculus from said teeth which comprises contacting said teeth with a sufficient and effective amount to achieve said purpose of a mouthwash which is a liquefied composition of a therapeutically effective amount of a non-necrotic fatty acid compound prepared from an unsubstituted, unsaturated fatty acid having at least one double bond, water, a buffering agent and ethanol, the pH of said liquefied composition being between 9 and 11.
Claim 2
Independent Claim
81 words
The method of treating teeth for the removal of dental plaque and/or dental calculus from said teeth which comprises contacting said teeth with a sufficient and effective amount to achieve said purpose of a mouthwash which is a liquefied composition of a therapeutically effective amount of a non-necrotic fatty acid compound prepared from an unsubstituted, unsaturated fatty acid having at least one double bond, water, a buffering agent and ethanol, the pH of said liquefied composition being between 9 and 11.
Claim 3
Dependent Claim
43 words

Claim 9
Independent Claim
86 words
The method of treating teeth for the prevention or suspension of the formation of dental plaque and/or dental calculus on said teeth which comprises contacting said teeth with a sufficient and effective amount to achieve said purpose of a mouthwash which is a liquefied composition of a therapeutically effective amount of a non-necrotic fatty acid compound prepared from an unsubstituted unsaturated fatty acid having at least one double bond, water, a buffering agent and ethanol, the pH of said liquefied composition being between 9 and 11.
Claim 10
Independent Claim
86 words
The method of treating teeth for the prevention or suspension of the formation of dental plaque and/or dental calculus on said teeth which comprises contacting said teeth with a sufficient and effective amount to achieve said purpose of a mouthwash which is a liquefied composition of a therapeutically effective amount of a non-necrotic fatty acid compound prepared from an unsubstituted unsaturated fatty acid having at least one double bond, water, a buffering agent and ethanol, the pH of said liquefied composition being between 9 and 11.
