Background and aim: Regarding the prevalence of monolithic zirconia and glazed ceramics IPS-e.max, and inadequate research on the color change of chlorhexidine and listerine mouthwashes on these two types, this study was aimed to compare the effect of these two mouthwashes on the stability of the
The mentioned materials.
Materials and Methods: This experimental study was carried out in vitro. 38 samples of monolithic zirconia and glazed ceramics IPS-e.max were prepared. The primary color was measured by spectrophotometry. The samples were randomly assigned to chlorhexidine, listerine and water mouthwashes. Developments for 7 days, every 2 minutes, in chlorhexidine 0/0 0.2%, Listerine Zero Then the secondary color was again measured by spectrophotometry and (4) ΔE ab were evaluated by Kruskal Wallis test.
Results: Both types of ceramics after the immersion in two types of mouthwash and distilled water were changed as control. ΔE values of the two substance after being placed in chlorhexidine (Monolithic zirconium (ΔE = 0.16 ± 0.11) and glazed ceramics IPS-e.max
(ΔE = 0.39 ± 0.14) showed a significant difference compared to the initial colorimetry (P<0.001).Also, the amounts of ΔE, two substances after placement in Listerine (monolithic zirconium (ΔE = 0.26 ± 0.17) and glazed ceramics IPS-e.max (ΔE = 0.48 ± 0.29) compared to colorimetric Primary difference was not significant (p <0.06). Kruskal Wallis test showed that this difference ΔE was significant between the four groups (p <0.02).
Conclusion: The color consistency of both monolithic zirconium and Ips.emax ceramics seems to be clinically acceptable. |
