Abstract: Bacteria affect human life，and oral bacterial infection can also cause periodontitis and peri-implantitis. The antibacterial effect of nanomaterials has been widely studied. For dental implants，implant surface material modification has become a method to prevent bacterial infection. The antibacterial effect of molybdenum disulfide（MoS2）-based materials is mainly through electron transfer，which results in reactive oxygen species（ROS）and glutathione（GSH）oxidation-reduction and thus destroys bacteria，often acting synergistically in a multi-antimicrobial manner. This article reviews the research progress of antibacterial coating on MoS2-based titanium surfaces in the field of dental implantology.

Key words: antibacterial material, molybdenum disulfide, MoS2, implant surface coating

摘要： 细菌影响人类生活，口腔细菌感染还会引起牙周炎和种植体周围炎等疾病。纳米材料的抗菌作用已被广泛研究，对于口腔种植而言，种植体表面材料改性已成为预防细菌感染的一种方法，其中二硫化钼（MoS2）基材料抗菌主要是通过电子转移从而导致活性氧（reactive oxygen species，ROS）和谷胱甘肽（glutathione，GSH）的氧化还原作用破坏细菌，通常为多重抗菌方式协同作用。文章就MoS2基钛表面抗菌涂层在口腔种植领域相关研究进展做一综述。
