Abstract: Oral cavity is a complex biological environment where a variety of bacteria exist. Flora imbalance will lead to various oral diseases. Many scholars have found that graphene and its derivatives have strong antibacterial effects on the pathogens of common oral diseases, so it can be used as a new type of antibacterial material in oral cavity. This paper mainly reviews the antibacterial mechanism of graphene and its derivatives, and summarizes its antibacterial applications in stomatology.

Key words: graphene, graphene derivatives, antibacterial properties
