Abstract

Amaç: Bu çalışmanın amacı, renklendirme solüsyonunda farklı sürelerde bekletmenin ve farklı yüzey bitirme işlemlerinin kendinden renkli ve renksiz monolitik zirkonya üzerindeki renk değişiminin incelenmesidir.
Gereç ve Yöntem: Monolitik zirkonyadan hazırlanan 240 adet örnek, renklendirme solüsyonunu rengine (A1, A2 ve A3), solüsyonda bekletme süresine (3, 5, ve 7 dakika) ve yüzey bitirme işlemlerine (glaze ve mekanik parlatma) göre gruplara ayrıldı (n=10). Örneklerin CIE L *, a * ve b * değerleri ölçüldü ve renk farklılıkları (ΔE) hesaplandı. Veriler üç yönlü varyans analizi (ANOVA) ve Tukey HSD testi (α =.05) ile analiz edildi.
Bulgular: Solüsyon ile renklendirme, bekletme süresi ve yüzey bitirme işlemleri CIE L*, a* ve b* değerlerini (P<.001) önemli ölçüde etkiledi. Solüsyonla renklendirme uygulaması a* ve b* değerlerini azalttı. Glaze gruplarında mekanik polisaj gruplarından daha yüksek L* değerleri elde edildi. Gruplar arasındaki ΔE değerleri 7,10 ile 27,52 arasında değişmektedir. En yüksek renk farkı, A3 renkli solüsyonun 7 dk. uygulandığı ve mekanik polisaj uygulanan gruplarda gözlemlendi.
Sonuç: Kendinden renkli ve solüsyonla renklendirilmiş zirkonya örnekler arasındaki renk farkı kabul edilebilir sınırlar içinde değildir. Renklendirme solüsyonlarında bekletme ve yüzey bitirme işlemleri solüsyon ile renklendirilen monolitik zirkonyanın rengini etkilemektedir.

Effects of dipping time in coloring liquids and surface finishing technique on the color of monolithic zirconia

Abstract

Objective: The objective of this study was to investigate the effects of liquid coloring in different dipping times and finishing procedures on color difference of precolored and liquid-colored monolithic zirconia ceramics.
Materials and Methods: 240 zirconia specimens were divided according to shades of coloring liquid (A1, A2, and A3), dipping time (3, 5, and 7 minutes), and surface finishing procedures (glaze and mechanical polishing) (n=10). CIE L*, a*, and b* values of the specimens were measured and color differences (ΔE) were calculated. The data were analyzed with three-way analysis of variance (ANOVA) and Tukey HSD test (α=.05).
Results: Coloring with liquids, dipping time, and finishing procedures significantly affected the CIE L*, a*, and b* values (P<.001). Dipping in coloring liquids decreased the a* and b* values. Higher L* values were obtained in glazing groups than mechanical polishing groups. The ΔE values among the experimental groups were varied from 7.10 to 27.52. The highest color difference was observed in 7 min dipping in A3 liquid and mechanically polished group.
Conclusion: The color difference between the precolored and liquid-colored zirconia ceramics are not in acceptable limits. Dipping in coloring liquids and surface finishing affect the color of liquid-colored monolithic zirconia.
