Abstract: Composite resin is the most widely used material in clinical dental restoration. However，it still has the disadvantages of low strength，poor wear resistance，being easy to have micro-leakage and secondary caries，so the researches on improving the performance of composite resins have never stopped. Compared with other repair materials，bacteria on the composite resin are more likely to adhere and aggregate to form plaque biofilm. Adding an antibacterial agent to the composite resin has become an important means，but the effect of the antibacterial agent on the mechanical properties，physical and chemical properties，and cytotoxicity of the composite resin also requires further study. The research progress in effects of antibacterial agents on the general properties of the composite resin is reviewed in this paper.

Key words: composite resin, antibacterial property, mechanical properties, cytotoxicity
