摘要

目的:通过仪器和视觉分析,评价单色树脂复合材料漂白前后的配色。方法:在80颗提取的人类臼齿的颊面上形成V类蛀牙,用4种单一阴影复合材料(Omnichroma;Clearfil Majesty ES-2 Universal;Essentia Universal;Venus Diamond One)修复。使用分光光度计(VITA Easyshade V)在牙齿漂白(Opalescence Boost PF 40%)前(T0)、24小时(T1)和一周(T2)评估牙齿/树脂的颜色匹配。计算并统计分析牙齿漂白前后的颜色变化(ΔE00)(P<0.05)。结果:分光光度法评估显示,在T0、T1和T2时,材料之间存在统计学上的显著差异(P<0.05)。视觉分析报告了优异和非常好的等级(分别为0和1),无论材料和时间点如何。结论:数据表明,当周围牙齿受到漂白作用时,单一色调的复合材料能够改变颜色。在专业漂白前后,单色复合材料似乎与周围的牙齿结构实现了良好的颜色匹配。

Effect of bleaching on the color match of single-shade resin composites.

Purpose: To evaluate the color match of single-shade resin composites before and after bleaching procedures, through instrumental and visual analyses.

Methods: Class V cavities were created on the buccal surfaces of 80 extracted human molars, restored with 4 single-shade composites (Omnichroma; Clearfil Majesty ES-2 Universal; Essentia Universal; Venus Diamond One). A spectrophotometer (VITA Easyshade V) was used to evaluate the tooth/resin color match before (T0), and 24 h (T1) and one week (T2) after dental bleaching (Opalescence Boost PF 40%). Color variations (ΔE00) were calculated and statistically analyzed (P < 0.05). Visual analysis was performed before and after tooth bleaching.

Results: Spectrophotometric evaluations revealed statistically significant differences between materials at T0, T1, and T2 (P < 0.05). Visual analysis reported excellent and very good grades (0 and 1, respectively), irrespective of the materials and timepoints.

Conclusion: Data seem to indicate that single shade composites are able to shift their color when the surrounding tooth undergoes bleaching effects. Single-shade composites seem to achieve a good color match with the surrounding tooth structure, before and after professional bleaching.
