Abstract:
Objective:To evaluate the effects of different surface treatment methods and simulated aging on the roughness, microhardness, and color stability of lithium disilicate glass ceramics(LDC).
Methods:The LDC were grouped and performed 5 kinds of surface treatments: control group, polishing group, polishing+polishing paste group, glazing group, polishing+glazing group. The roughness and microhardness of the specimen were measured. Then the specimens were divided into two subgroupswhich were treated with water and staining solution. The specimens were measured color parameters before and after processing. The above data was analyzed.
Results:The LDC had changes in surface roughness and microhardness after different surface treatments. The polishing+polishing paste group had the lowest surface roughness, and the surface microhardness of the LDC decreased after glazing. After simulating aging, the difference of color and transparency of the polishing+polishing paste group, glazing group, and polishing+glazing group were the smallest.
Conclusion:Different surface treatments and simulated aging have a certain impact on the roughness, microhardness, and color stability of LDC. Fine polishing with polishing paste has a comparable anti staining effect to glazing on LDC.
