Abstract

Objective: This study aimed to evaluate the color stability of 3D printed permanent and temporary composite-based restorative materials by assessing their stainability after immersion in tea, coffee, and water.
Methods: The composite resins used included Temp Ultra (TU) and Custom Composite Resin (CR) (for temporary restorations) and Crowntec (for permanent restorations). Specimens were 3D printed, post-polymerized, and polished. They were then immersed in tea, coffee, or water at 37°C for 7 days. Color changes were measured using the CIE Lab* system and analyzed using IBM SPSS 26, with ΔE00 values compared to clinical thresholds.
Results: After 7 days, the greatest color change (ΔE00) was observed in all coffee-immersed groups, with the TU + coffee group showing the highest ΔE00 value (2.38 ± 0.21), exceeding the clinically acceptable threshold of 2.25. The CR + water group exhibited the least color change (0.16 ± 0.05). Color changes in tea-immersed groups were statistically significant, with CR showing reduced color change (1.97 ± 0.15). Only the coffee-exposed groups exceeded the acceptable ΔE00 value.
Conclusion: The study found that the type of composite material significantly affects color stability, with Temp Ultra showing the most color change in coffee. The results suggest that while these materials demonstrate acceptable color stability.

3D BASKI GEÇİCİ VE KALICI KOMPOZİT REÇİNELERİN GENEL İÇECEKLERE MARUZ KALMA SONRASI RENK STABİLİTESİNİN DEĞERLENDİRİLMESİ

Abstract

Amaç: Bu çalışma, 3D baskılı kalıcı ve geçici kompozit bazlı restoratif materyallerin çay, kahve ve suya batırıldıktan sonra lekelenebilirliklerini değerlendirerek renk stabilitesini değerlendirmeyi amaçladı.
Gereç ve Yöntem: Kullanılan kompozit reçineler arasında Temp Ultra ve Custom Composite Resin (geçici restorasyonlar için) ve Crowntec (kalıcı restorasyonlar için) yer aldı. Numuneler 3D olarak basıldı, polimerize edildi ve cilalandı. Daha sonra 7 gün boyunca 37°C'deki çay, kahve veya suya batırıldılar. Renk değişiklikleri CIE Lab* sistemi kullanılarak ölçülmüş ve IBM SPSS 26 ile klinik eşik değerlerine kıyasla ΔE00 değerleri ile analiz edilmiştir.
Bulgular: 7 gün sonra en büyük renk değişimi (ΔE00) kahveye batırılan tüm gruplarda gözlemlendi; TU + Kahve grubu en yüksek ΔE00 değerini (2,38 ± 0,21) göstererek klinik olarak kabul edilebilir eşik olan 2,25'i aştı. CR + Su grubu en az renk değişimini sergiledi (0,16 ± 0,05). Çaya batırılan gruplardaki renk değişiklikleri istatistiksel olarak anlamlıydı; CR, renk değişiminde azalma gösterdi (1,97 ± 0,15). Yalnızca kahveye maruz kalan gruplar kabul edilebilir ΔE00 değerini aştı.
Sonuç: Çalışma, kompozit malzeme türünün renk stabilitesini önemli ölçüde etkilediğini, Temp Ultra'nın kahvede en fazla renk değişimini gösterdiğini buldu. Sonuçlar, çalışmada kullanılan materyaller kabul edilebilir renk stabilitesi göstermişlerdir
