Abstract

Amaç: Bu in vitro çalışmanın amacı, farklı kimyasal kompozisyona sahip çeşitli kalınlıklardaki üç farklı CAD-CAM materyalinin opalaseans parametresi (OP) ve kontrast oranının (CR) karşılaştırılmasıdır.
Gereç ve Yöntem: Doksan adet A2 renkte örnek; lösitle güçlendirilmiş feldspatik seramik (LS, G-Ceram), lityum disilikat seramik (LD, IPS e.max CAD) ve rezin nano seramik (RN, Lava Ultimate) CAD-CAM bloklardan 0,5 mm, 0,7 mm ve 1 mm kalınlığında olacak şekilde hazırlandı (n=10). Renk ölçümleri siyah ve beyaz arka planlar üzerinde bir spektrofotometre ile gerçekleştirilerek CIE L*a*b* verileri kaydedildi. Örneklerin OP ve CR değerleri hesaplandı. İstatistiksel analiz iki yönlü ANOVA ve Bonferroni testleri ile yapıldı (α=0,05).
Bulgular: Materyal ve kalınlık temel etkisi ile materyal ve kalınlık etkileşimi OP ve CR için önemli bulundu (P<0,001). OP değeri üzerinde materyal tipinin etkisi kalınlık etkisinden daha yüksek olurken (ηp2=0,973), CR değeri üzerinde kalınlığın etkisi (ηp2=0,879) daha fazla bulundu. En yüksek ortalama OP değeri RN grubunda, en düşük ortalama OP değeri ise LS grubunda elde edildi (P<0,001). Kalınlığı 0,7 mm ve 1 mm olan örnekler benzer OP değerleri sergilerken, 0,5 mm kalınlığındaki örnekler istatistiksel olarak daha düşük OP değeri gösterdi (P<0,05). LD ve RN grupları benzer CR değerleri sergiledi (P>0,05) ancak LS grubu daha yüksek ortalama CR değeri gösterdi (P<0,001). Her üç materyal 1 mm kalınlığında benzer CR değerleri sergilese de 0,5 mm ve 0,7 mm kalınlığındaki LD ve RN grupları LS grubuna kıyasla daha düşük CR değerleri gösterdi (P<0,05).
Sonuç: Materyal tipi ve kalınlığı OP ve CR değerlerini etkilemiştir. Kalınlık arttıkça CR azalmakta ancak OP artmaktadır. Kalınlık CR parametresini materyal tipine kıyasla daha çok etkilemiştir. Materyal tipi ise opalesans parametresini kalınlığa kıyasla daha çok etkilemiştir.
