Abstract

Abstract: Objective: To study the effects of combined application of rein infiltration and bioactive glass on enamel caries. Method: 51 extracted human teeth prepared as artificial incipient enamel caries were randomly divided into 5 groups. They were treated with resin infiltration (group A), 0.6% bioactive glass (group B), 0.1% sodium fluoride solution (group C), 0.6% bioactive glass solution (group D), and blank control group (E group) for 4 weeks. Scanning electron microscope observation and surface microhardness measure were made before and after demineralization. Result: SEM observation showed that the surface porosity of A-D group was significantly reduced after 4 weeks treatment, and surface smoothness of group D was the best. After treatment, the values of ΔSMH1 ranged from large to small in the order of D, C, A, B, E. There was significant difference in the ΔSMH1 values between groups except group A and group B. Conclusion: The resin infiltration combined with bioactive glass could effectively repair early enamel caries.
