چکیده: (245 مشاهده)
Background and Aim: This study aimed to assess the effects of chlorhexidine (CHX) and Listerine mouthwashes on color stability of glazed bilayer zirconia and IPs e.max ceramics.
Materials and Methods: This in vitro experimental study was conducted on 36 glazed bilayer zirconia and IPS e.max ceramic specimens. The baseline CIE L*a*b* color parameters of specimens were measured by a spectrophotometer. The bilayer zirconia and IPS e.max ceramic specimens were then randomly assigned to two subgroups for immersion in 10 mL of 0.2% CHX (n=9) and 10 mL of Listerine (n=9). The specimens were immersed in the respective solutions for 2 minutes daily for 7 days. Next, their color parameters were spectrophotometrically measured again. The color change (∆E) of ceramics in the three groups was calculated and compared by the Kruskal-Wallis test and two-way ANOVA (alpha=0.05).
Results: The L*, a*, and b* color parameters of glazed bilayer zirconia and IPs e.max ceramic specimens were not significantly different at baseline (P=0.8) or after the intervention (P=0.6). The ∆E of the subgroups was not significantly different either (P>0.05).
Conclusion: Both glazed bilayer zirconia and IPs e.max ceramics showed clinically acceptable color stability (∆E<3.3) following immersion in CHX and Listerine mouthwashes.
