Abstract

Abstract A method of and system for the treatment of periodontal diseases is disclosed wherein a patient, using a delivery device, applies a medicament directly to the infected site. The delivery device may comprise a piece of tufted dental floss, an interdental brush, a syringe, or a night time application tray for forcibly applying medicament to the infected site. The delivery device carries a supply of an antimicrobial or antibiotic medicament, preferably a tetracycline, dichloride or hydrogen peroxide solution or gel. By flossing, brushing, injecting, or by forcibly disbursing the medicament with the delivery device, the patient can apply the medicament directly on or in close proximity to the infected site (i.e., bony support structure of the teeth). The medicament (tetracycline) bonds with the bony structure to promote bone regeneration, decrease osteoclastic activity and to allow osteoblastic activity to continue with a consequent decrease in bone loss rate while promoting bone growth (regeneration). Through the use of an oxygenation agent (hydrogen peroxide), fluoride, dichloride, or other medicaments, microbial activity, plaque development, and pathologic processes are decreased.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 134 words
A system for treatment of a patient having gum disease, said patient having gums and bony structure for supporting teeth, said system comprising a length of dental floss having a supply of a medicament thereon sufficient for delivering said medicament to the bony structure or subgingivally below the gum line and for treating a plurality of disease sites, said dental floss being capable of being used by said patient without help from a dental professional so as to deliver said medicament to said bony structure supporting said teeth and so as to at least partially effect bonding of said medicament with said bony structure thereby to provide a residual medication action on said bony structure after said dental floss has been removed so as to impede deterioration of said bony structure and said gums.
Claim 2
Independent Claim 134 words
A system for treatment of a patient having gum disease, said patient having gums and bony structure for supporting teeth, said system comprising a length of dental floss having a supply of a medicament thereon sufficient for delivering said medicament to the bony structure or subgingivally below the gum line and for treating a plurality of disease sites, said dental floss being capable of being used by said patient without help from a dental professional so as to deliver said medicament to said bony structure supporting said teeth and so as to at least partially effect bonding of said medicament with said bony structure thereby to provide a residual medication action on said bony structure after said dental floss has been removed so as to impede deterioration of said bony structure and said gums.
Claim 3
Dependent Claim 12 words
The system of claim 1 wherein said medicament is an antimicrobial medicament.
Claim 4
Dependent Claim 14 words
The system of claim 2 wherein said antimicrobial medicament is a solution of tetracycline.
Claim 5
Dependent Claim 25 words
The system of claim 3 wherein said tetracycline solution has the tetracycline equivalent of about 125 mg of tetracycline hydrochloride in a 5 ml quantity.
