Abstract:
Objective:To evaluate the characteristics of bonding interface and microstructure of different resin composite inlays. Methods:Different composite resins and adhesives were used for restoration of extracted molars, the results were evaluated under scanning electron microscope(SEM) and atomic force microscope(AFM).Results:The microstructure feature of Tescera was with higher density when compared with that of other conventional resins,and fewer small holes could be seen in Tescera. AFM pictures showed that Tescera was with a very smooth surface. Indirect composite resin could be combined with resin bonding agent tightly and infiltrated each other. The interface between direct resin inlay material and resin bonding agent was very clear,and no obvious interfiltration could be seen under SEM and AFM. Conclusion:After treatment with water, heat,light and pressure, the physical properties of indirect composite resin is improved effectively, and obvious infiltration can be found in the interface.
