Effect of Different Surface Finishing Methods and Colorant Solutions on Translucency of Monolithic CAD/CAM Ceramics

Objective: An ideal aesthetic restoration should be morphologically and optically compatible with the natural teeth and, at the same time, biologically acceptable. The translucency of the restoration is the most important factor in achieving a natural tooth appearance. The aim of this study was to compare the translucency parameters (TPs) of two types of monolithic computer-aided design/computeraided manufacturing (CAD/CAM) ceramics, Vita Suprinity HT (VS) and IPS e.max CAD HT (IPS), after utilizing three different surface finishing methods and being exposed to cola, coffee, and black tea solutions. Materials and Methods: A total of 24 groups consisting of 10 samples each were created from VS and IPS e.max CAD ceramics. Glaze, Shofu polishers, and Sof-lex polishing discs were used to finish the surface of the ceramics. Cola, coffee, and black tea were used as coloring solutions. For the control groups, samples were kept in distilled water. The TP was determined for optical properties. Data were statistically analyzed using three-way analysis of variance (ANOVA). The Bonferroni test was used for multiple comparisons. Results: Material, method, group and interaction effects were found statistically significant (p

Farklı Yüzey Bitirme İşlemlerinin ve Renklendirici Solüsyonların Monolitik CAD/CAM Seramiklerin Translüsensisi Üzerine Etkisi

Amaç: İdeal bir estetik restorasyon, doğal dişlerle morfolojik ve optik olarak uyumlu aynı zamanda biyolojik olarak kabul edilebilir olmalıdır. Restorasyonun translüsensisi doğal diş görünümü için en önemli faktördür. Bu çalışmanın amacı, Vita Suprinity HT (VS) ve IPS e.max bilgisayar destekli tasarım (CAD) HT (IPS) olmak üzere iki tip monolitik CAD bilgsayar destekli üretim (CAM) seramiğine üç farklı yüzey sonlandırma işleminin uygulanmasının ardından kola, kahve ve siyah çaya maruz bırakılarak seramiklerin translüsensi parametresini (TP) karşılaştırmaktır. Gereç ve Yöntemler: VS ve IPS e.max CAD seramiklerinden her birinde 10 örnekten oluşan toplam 24 grup oluşturuldu. Seramiklerin yüzeyini bitirmek için glaze, Shofu polisajları ve Sof-lex polisaj diskleri kullanıldı. Renklendirme çözeltisi olarak kola, kahve ve siyah çay seçildi. Kontrol grupları için, örnekler damıtılmış suda tutuldu. Optik özellikler için TP belirlendi. Veriler, üç yönlü varyans analizi kullanılarak istatistiksel olarak analiz edildi. Çoklu karşılaştırma için Bonferroni testi kullanıldı. Bulgular: Materyal, yöntem, grup ve etkileşim etkileri istatistiksel olarak anlamlı bulundu (p
