Objective.
To determine the influence of the home bleaching agent, Opalescence PF, on the surface roughness and microhardness of glazed glassy matrix CAD-CAM ceramics.
Materials and Methods.
The 28 sintered leucite- and lithium disilicate-reinforced ceramic specimens (IPS Empress CAD and IPS e.max CAD) were divided into control and bleached groups.
The home bleaching agent was applied to specimens of bleached groups for 7 days.
The surface roughness and microhardness of all specimens were measured.
A scanning electron microscope was used to evaluate the surface properties.
The data were statistically analyzed by two-way ANOVA.
Results.
The control e.max CAD showed the lowest surface roughness values.
For both Empress and e.max CAD, surface roughness was significantly higher for the bleached group (p<0.05).
No significant differences in microhardness were observed.
Conclusions.
According to our study, patients should be careful when using home bleaching agents because whitening agents can affect the mechanical properties of full ceramic restorations like e.max CAD and Empress CAD.
Ceramic polishing may be required in clinical situations where ceramic restorations are accidentally exposed to bleaching gels.
