Patent ID: 8795638

Claim:
A method of treating oral diseases in the mouth, said method comprising the step of applying to the target area of the mouth an oral treatment composition comprising a controlled release, oral tissue-adherent salt comprising C8-C18 monocarboxylic acid anionic and N α -(C8-C18)acyl(C2-C18) alkyl ester of a dibasic amino acid cationic components, whereby said salt has (i) an aqueous solubility from about 200 ppm to about 10,000 ppm enabling it to release dissolved biocidal or biostatic cations into the oral fluid at a concentration that is equal to or exceeds the minimum bactericidal concentration (MBC) or minimum inhibitory concentration (MIC) of the target bacteria, while (ii) the aqueous solubility of said salt is appropriately limited to leave undissolved, un-dissociated salt on the oral tissues to which it was applied, to act as a reservoir to allow the subsequent release of additional biocidal or biostatic ions into the mouth, to replace the dissolved biocidal or biostatic ions as they are used up or otherwise depleted, thereby maintaining an essentially uniform concentration of biocidal or biostatic ions equal to or exceeding the MBC or MIC of the target bacteria in the oral fluid in the treated area of the mouth for an extended period of time.
