This study aimed to evaluate and compare the color matching of OMNICHROMA (OM), a universal shade composite, to the well-established 3M Filtek Z350 composites (FT).
An experimental study was conducted on 80 freshly extracted permanent teeth, with intact buccal surfaces. The teeth were randomly assigned to four groups: Group I OM and groups II, III, and IV (3M Filtek Z350 in shades A3, A3.5, and B2, respectively). Class V cavity preparations were created and restored using the respective composites. Color matching was assessed instrumentally using a spectrophotometer to calculate the color difference (Δ) values and visually by three trained observers using a standardized visual scoring system.
Visual assessments showed no significant differences in color matching across the four groups. However, the Δ color matching analysis revealed significant differences ( < 0.0001), with OM exhibiting higher Δ values compared to FT shades A3.5 and B2. No significant difference was found between OM and shade A3.
OMNICHROMA demonstrated excellent visual color matching, comparable to the various shades of FT composites. Despite the higher Δ values observed instrumentally in comparison to shades A3.5 and B2, OM's ability to blend with different tooth shades visually was highly effective.
These results suggest that OM offers a versatile and reliable option for achieving satisfactory esthetic outcomes, reducing the need for multiple shade variations in restorative procedures.

本研究旨在评估和比较通用色度复合树脂OMNICHROMA(OM)与成熟的3M Filtek Z350复合树脂(FT)的颜色匹配情况。
对80颗颊面完整的新鲜拔除恒牙进行实验研究。将牙齿随机分为四组:第一组为OM,第二、三、四组分别为3M Filtek Z350的A3、A3.5和B2色号。制备V类洞型并使用相应的复合树脂进行修复。使用分光光度计通过仪器评估颜色匹配情况以计算色差(Δ)值,并由三名经过培训的观察者使用标准化视觉评分系统进行视觉评估。
视觉评估显示四组之间在颜色匹配上无显著差异。然而,Δ颜色匹配分析显示存在显著差异(<0.0001),与FT的A3.5和B2色号相比,OM表现出更高的Δ值。OM与A3色号之间未发现显著差异。
OMNICHROMA表现出出色的视觉颜色匹配,与FT复合树脂的各种色号相当。尽管与A3.5和B2色号相比,通过仪器观察到OM的Δ值更高,但其在视觉上与不同牙齿色号融合的能力非常有效。
这些结果表明,OM为实现满意的美学效果提供了一种通用且可靠的选择,减少了修复过程中对多种色号变化的需求。如何引用本文:Bisharah WF, Zahran AS, Rajeh MT, 颜色匹配比较:通用色度复合树脂与多色号传统复合树脂。《当代牙科实践杂志》2024;25(11):1039 - 1044。
