Final Color of CAD-CAM Produced Thin Lithium Disilicate Ceramics Cemented with Different Colored Resin Cements on Darker Backgrounds
Öz
Aim: The aim of the present study was to evaluate the final color of CAD-CAM produced thin lithium disilicate ceramics cemented with A2, opaque, and bleach resin cements on darker backgrounds.
Materials and Method: Nine different experimental groups (n=10) were generated according to the colors of resin backgrounds (ND3:A3, ND4:A3.5, and ND8:A4) and cements (A2, opaque, and bleach). Target specimen was prepared by cementing lithium disilicate ceramic layer onto ND2 (A2) background by using translucent resin cement. The color difference values between experimental groups and target specimen were calculated according to CIEDE2000 formula. The data were statistically analyzed by using Kruskall Wallis test (α=0.05).
Results: The results showed that most of the experimental groups had higher color difference values than acceptability threshold (1.8) except ND3-A2 and ND3-opaque groups. It was observed that when the background got darker, the color difference values increased.
Conclusion: The darker backgrounds (A3, A3.5, and A4) and resin cement color (A2, opaque, and bleach) affected the final color of the lithium disilicate ceramics in 1 mm thickness. Color difference values were found in clinically acceptable limits for cementing lithium disilicate ceramics with A2 and opaque resin cements on A3 background.

Koyu Arka Plan Üzerine Farklı Renkteki Simanlarla Simante Edilen İnce Lityum Disilikat Seramiklerin Sonuç Rengi
Öz
Amaç: Bu çalışmanın amacı, koyu arka plan üzerine farklı renklerdeki (A2, opak ve bleach) rezin simanlar ile simante edilen CAD-CAM sisteminde üretilen ince lityum disilikat seramiklerin sonuç rengini değerlendirmektir.
Gereç ve Yöntem: Farklı arka plan (ND3:A3, ND4:A3.5 ve ND8:A4) ve rezin siman renklerine (A2, opak ve bleach) göre dokuz farklı deney grubu oluşturuldu (n=10). Hedef renge sahip
örnek, lityum disilikat seramik tabakanın ND2 (A2) arka plan üzerine translusent rezin siman ile simantasyonuyla hazırlandı. Hedef örnek ve deney grupları arasındaki renk farkı değerleri CIEDE2000 formülü kullanılarak hesaplandı. Veriler Kruskall Wallis testiyle istatistik olarak analiz edildi (α=0.05).
Bulgular: ND3-A2 ve ND3-opak grupları dışındaki deney grupları, kabul edilebilirlik eşik değerinin (1.8) üzerinde renk farkı değerleri gösterdi. Arka plan rengi koyulaştığında, renk farkı değerlerinin yükseldiği belirlendi.
Sonuç: Daha koyu arka plan (A3, A3.5 ve A4) ve siman rengi (A2, opak ve bleach) 1 mm kalınlığındaki lityum disilikat seramiklerin sonuç rengini etkilemektedir. A2 ve opak renklerdeki rezin simanlar ile A3 arka plan üzerine simante edilen lityum disilikat seramiklerde renk farkı değerleri klinik olarak kabul edilebilir sınırlar içindedir.
