Abstract: A bone-repairing agent excellent in workability and applicability to clinical surgical techniques and having a drastically enhanced bone formation rate, obtained by including an elastin hydrolysate in a complex of DNA and at least one selected from the group consisting of protamine, a protamine derivative, and a protamine hydrolysate can be provided. A medical or dental material for bone formation using this bone-repairing agent can be provided.

Abstract: A medical or dental material can be prepared by using, as an active ingredient, at least one of a protamine, and derivatives thereof and hydrolysates thereof, or a complex of at least one of a protamine, and derivatives thereof and hydrolysates thereof with an anionic high molecular weight compound. As a result, an antibacterial agent against periodontal disease-causing bacteria can be provided, which is highly safe without concern of a side effect. A medical or dental material can be also provided, which exhibits antimicrobial activity on periodontal disease-causing bacteria and additionally has insolubility in water and good formability.
