Antibacterial Property of a Polyethylene Glycol-Grafted Dental Material

Abstract

Dental materials often cause bacterial adhesion and promote bacterial biofilm formation, which brings a series of long-standing and significant problems in oral health. However, the current development of antibacterial research in dental devices is limited by the lack of materials endowed with good antibacterial properties against oral bacteria. Here, we present a new strategy for reducing the initial adhesion of bacterial on dental biomaterials by chemically bonding long-chain polyethylene glycol. Our work represents an important step toward solving the problem of bacterial accumulation on dental devices.
