Abstract

Objective: To compare the CIE L*, a*, and b* color parameters of various 3D-printed and direct composite resins, all labeled with the A2 shade, and to evaluate whether their color differences (ΔE₀₀) relative to the VitaPan A2 reference standard remain within clinically acceptable thresholds. Materials and Methods: Three direct resin composites and two ceramic-filled 3D-printed crown resins were evaluated. For each material, six disc-shaped specimens (10 mm × 2 mm) were fabricated, all corresponding to the Vita A2 shade. Color measurements were obtained using a spectrophotometer within the CIE L*a*b* color space. Color differences relative to the Vita Pan A2 standard were calculated employing the CIEDE2000 formula (ΔE₀₀). Statistical analyses were conducted using one-way ANOVA, followed by Bonferroni and Games-Howell post hoc tests (p < 0.05). Results: Significant differences were observed among the materials with respect to L*, a*, b*, and ΔE₀₀ values (p < 0.001). Crowntec exhibited the highest L* value, whereas Charisma Smart demonstrated the highest a* value. Charisma Smart, Crowntec, and Permanent Crown presented higher b* values compared to Estelite Sigma Quick and Filtek Z250. Although Filtek Z250 and Estelite Sigma Quick displayed comparable ΔE₀₀ values, only Filtek Z250 remained below the clinical acceptability threshold (ΔE₀₀ < 1.8), indicating an acceptable color match with the VitaPan A2 shade. Conclusion: Resin-based materials labeled as A2 showed significant differences in L*, a*, b*, and ΔE₀₀ values, indicating that the A2 shade label does not ensure a clinically acceptable color match with the VitaPan A2 shade, as only Filtek Z250 exhibited ΔE₀₀ values below the threshold for clinical acceptability.

Özet

Amaç: Bu çalışma, tümü A2 tonuyla etiketlenmiş çeşitli 3D baskılı ve direkt kompozit rezinlerin CIE L*, a* ve b* renk parametrelerini karşılaştırmayı ve VitaPan A2 referans standardına göre renk farklılıklarının (ΔE₀₀) klinik olarak kabul edilebilir eşik değer içinde kalıp kalmadığını değerlendirmeyi amaçlamıştır. Gereç ve Yöntem: Üç direkt kompozit rezin ve iki seramik dolgulu 3D baskılı kuron rezini değerlendirilmiştir. Her malzeme için, Vita A2 tonuna karşılık gelen altı adet disk şeklinde numune (10 mm × 2 mm) üretildi. Renk ölçümleri, CIE L*a*b* renk uzayında bir spektrofotometre kullanılarak elde edildi. Vita Pan A2 standardına göre renk farkları, CIEDE2000 formülü (ΔE₀₀) kullanılarak hesaplandı. İstatistiksel analizler tek yönlü ANOVA kullanılarak gerçekleştirilmiş, ardından Bonferroni ve Games-Howell post hoc testleri uygulanmıştır (p < 0,05). Bulgular: L*, a*, b* ve ΔE₀₀ değerleri açısından malzemeler arasında önemli farklılıklar gözlemlenmiştir (p < 0,001). Crowntec en yüksek L* değerini gösterirken, Charisma Smart en yüksek a* değerini göstermiştir. Charisma Smart, Crowntec ve Permanent Crown, Estelite Sigma Quick ve Filtek Z250'ye kıyasla daha yüksek b* değerleri sergilemiştir. Filtek Z250 ve Estelite Sigma Quick benzer ΔE₀₀ değerleri sergilemiş olsa da, sadece Filtek Z250 klinik kabul edilebilirlik eşiğinin altında kalarak (ΔE₀₀ < 1,8), VitaPan A2 tonuyla kabul edilebilir bir renk uyumu olduğunu göstermiştir. Sonuç: A2 olarak etiketlenen rezin bazlı malzemeler L*, a*, b* ve ΔE₀₀ değerlerinde önemli farklılıklar göstermiştir. Bu, A2 renk etiketinin VitaPan A2 rengiyle klinik olarak kabul edilebilir bir renk uyumu sağlamadığını göstermektedir, çünkü sadece Filtek Z250 klinik kabul edilebilirlik eşiğinin altında ΔE₀₀ değerleri sergilemiştir.
