Abstract

Dental products such as toothpastes, mouthwash and dental floss are disclosed which products are enhanced by having dissolved, dispersed or coated thereon a compound which promoted bone growth. Preferred compounds are peptide sequences comprising 10 to 50 amino acids are disclosed. The sequences are characterized by containing an integrin binding motif such as RGD sequence and the remainder of amino acids contiguous with the RGD sequence in matrix extracellular phosphoglycoprotein. The sequences may be formulated for dispersed in toothpaste or a mouthwash and administered to enhance bone/tooth growth. When the dental products are used repeatedly over time they enhance good dental health.

Claims (18)

1. A dental product, comprising:

a base material chosen from paste of a toothpaste, liquid of a mouthwash, and fiber of a dental floss; and

a peptide consisting of ten to fifty amino acids, wherein the peptide is comprised of an RGD integrin binding motif and further wherein the peptide is characterized by biological activity which enhances bone growth.

2. The dental product of claim 1 , wherein the peptide is contiguous with an RGD sequence of naturally occurring protein matrix extracellular phosphoglycoprotein.

3. The dental product of claim 1 , wherein the peptide consists of 15 to 35 amino acids.

4. The dental product of claim 1 , wherein the amino acids are in the L-conformation.

5. The dental product of claim 1 , wherein the peptide is chosen from:
