| 主权项 | 1. A dental care product, comprising: an orally acceptable carrier or excipient; and equal to or more than 0.1 mg/ml of a first bacterial resistance copolymer, including a zwitterionic block and an anchoring block with a first electricity, wherein the anchoring block with the first electricity binds to tooth surfaces by electrostatic attraction, and the zwitterionic block extends outwardly to reduce the attachment of bacteria to tooth surfaces; wherein the zwitterionic block is polymerized by a zwitterionic monomer selected from the group consisting of sulfobetaine, carboxylbetaine, derivatives thereof, and combinations thereof; and the anchoring block with a first electricity is derived from 11-mercapto-N,N,N-trimethylammonium chloride or 11-mercaptoundecyl sulfonic acid. | ||
