Topical copper ion treatments and methods of treatment using topical copper ion treatments in the oral-respiratory-otic areas of the body

A method of treating conditions affecting the oral cavity, consisting of the steps of

• spraying into the oral cavity a copper ion-containing solution consisting of copper ions, a biocompatible solution, and a buffer, wherein the buffer has a pH of 5±0.4, wherein the copper ions are disposed in the copper ion-containing solution as a result of leaching the copper ions from a solid copper metal disposed in the biocompatible saline solution and buffer, wherein the solid copper metal is a copper alloy, and wherein the buffer is a biocompatible solution consisting of a solvent, acetic acid, and acetate;
• and
• repeating said step of spraying for a number of consecutive days.

A method of treating conditions affecting the oral cavity, consisting of the steps of:

• spraying into the oral cavity a copper ion-containing solution consisting of copper ions, a biocompatible saline solution, and a buffer comprising at least one of acetate and acetic acid, wherein the buffer has a pH of 5±0.4, wherein the copper ions are disposed in the copper ion-containing solution as a result of leaching the copper ions from a solid copper metal disposed in the biocompatible saline solution and buffer, wherein the solid copper metal is a copper alloy, and wherein the copper ion-containing solution is free or substantially free of active ingredients other than copper ions;
• and
• repeating said step of spraying for a number of consecutive days.
