Dental resin composites have been widely used in clinical due to their esthetics. However

the marginal gap is still a major problem for resin composite restorative materials

which then lead to the occurrence of secondary caries. In recent years

remineralizing resin composites have been developed to prevent or decrease dental secondary caries

which can release remineralizing agents

such as calcium and phosphate ions. This review summarizes the effects of the kinds

particle size and surface treatment of bioactive filler on the physical and mechanical properties of resin composites

focusing on the remineralization behavior of the remineralizing dental composites. It was found that a variety of bioactive dental resin composites are able to promote remineralization. This suggests that remineralizing rein composites have the potential to slow the development and propagation of secondary caries at restoration margins.
