Abstract

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. . 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 ( < 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.

摘要

目的

确定家用漂白剂 Opalescence PF 对上釉玻璃基质 CAD-CAM 陶瓷表面粗糙度和显微硬度的影响。 将 28 个烧结的透锂长石增强和锂硅二酸盐增强陶瓷试件(IPS Empress CAD 和 IPS e.max CAD)分为对照组和漂白组。将家用漂白剂应用于漂白组的标本中 7 天。测量所有标本的表面粗糙度和显微硬度。使用扫描电子显微镜评估表面性能。通过双因素方差分析对数据进行统计分析。

结果

对照组 e.max CAD 的表面粗糙度值最低。对于 Empress 和 e.max CAD,漂白组的表面粗糙度显著更高(<0.05)。显微硬度无显著差异。

结论

根据我们的研究,患者在使用家用漂白剂时应小心,因为美白剂会影响 e.max CAD 和 Empress CAD 等全陶瓷修复体的机械性能。在陶瓷修复体意外暴露于漂白凝胶的临床情况下,可能需要进行陶瓷抛光。
