摘要

目的:评估漂白对不同 CAD/CAM 陶瓷材料表面粗糙度和光泽度的影响:评估漂白对不同 CAD/CAM 陶瓷材料表面粗糙度和光泽度的影响:陶瓷材料包括 IPS e.max CAD(二硅酸锂)、VITA ENAMIC(聚合物渗透陶瓷)和 Celtra Duo CAD(氧化锆增强硅酸锂)。每种材料的样本被随机分为四组(n = 10):对照组浸泡在蒸馏水中,第二组和第三组分别用 20% 过氧化碳酰胺(20% CP)和 35% 过氧化碳酰胺(35% CP)漂白剂处理,每天 4 小时和每天 60 分钟,持续 7 天。第四组使用 40% 过氧化氢(40% HP)漂白剂,每天两次,每次 20 分钟。处理后,使用扫描电子显微镜成像,评估表面粗糙度(使用三维非接触式轮廓仪)和表面光泽度。数据分析采用多元线性回归和 Kruskal-Wallis 单向方差分析(α = 0.05):不同漂白处理对 IPS e.max CAD 的表面粗糙度(p = 0.157)和光泽度(p = 0.073)没有显著影响。同样,Celtra Duo CAD 的表面粗糙度(p = 0.162)和光泽度(p = 0.965)也没有受到明显影响。另一方面,当使用 20% CP 和 35% CP 处理时,VITA ENAMIC 受到明显影响,粗糙度(p = 0.001)和光泽度(p = 0.008)均有所增加:家庭漂白处理(20% CP 和 35% CP)对 VITA ENAMIC 的表面粗糙度和光泽度有明显影响,而 IPS e.max CAD 和 Celtra Duo CAD 则不受不同漂白处理的影响。

The effect of bleaching on surface roughness and gloss of different CAD/CAM ceramic and hybrid ceramic materials.

Objective: To assess the effect of bleaching on surface roughness and gloss of different CAD/CAM ceramic materials.

Methods: The ceramic materials included IPS e.max CAD (lithium disilicate), VITA ENAMIC (polymer infiltrated ceramic), and Celtra Duo CAD (zirconia reinforced lithium silicate). Samples of each material were randomly divided into four groups (n = 10); a control group immersed in distilled water, the second and third groups were treated with 20% carbamide peroxide (20% CP) and 35% carbamide peroxide (35% CP) bleaching agents for 4 h/day and 60 min/day respectively for 7 days. The fourth group was treated with 40% hydrogen peroxide (40% HP) applied twice, each turn for 20 min. After treatment, the surface roughness (using 3D non-contact profilometry) and surface gloss were assessed followed by imaging with a scanning electron microscope. The data were analyzed using multiple linear regression and Kruskal-Wallis one-way ANOVA tests (α = 0.05).

Results: The surface roughness (p = 0.157) and gloss (p = 0.073) of IPS e.max CAD were not significantly affected by the different bleaching treatments. Similarly, no significant effect on surface roughness (p = 0.162) and gloss (p = 0.965) were shown for Celtra Duo CAD. On the other hand, VITA ENAMIC was significantly affected when treated with 20% CP and 35% CP showing increased roughness (p = 0.001) and gloss (p = 0.008).

Conclusions: Home bleaching treatments (20% CP and 35% CP) significantly affected the surface roughness and gloss of VITA ENAMIC while IPS e.max CAD and Celtra Duo CAD were not affected by the different bleaching treatments.
