Abstract

Objectives: The purpose of this study was to investigate the effect of material andthickness on the translucency parameters (TP) and opalescence parameters (OP) forresin matrix ceramic blocks.Materials and Methods: 90 disc-shaped specimens (8 mm diameter and A2 shade,High Translucency) were fabricated from Vita Enamic, Lava Ultimate and GCCerasmart resin-matrix ceramic blocks and prepared to thicknesses of 0.5 mm, 1 mmand 1.5 mm (n=10). A dental spectrophotometer (VITA Easyshade Advance) wasused to calculate the TP and OP. All specimens were placed on white and blackbackgrounds. The color measurements were repeated three times for each of thespecimens and the mean values of L, a and b were calculated. Data were analyzed bya two-way analysis of variance (ANOVA) and Tukey’s test.Results: For the 0.5 mm thickness groups, GC Cerasmart had the highest and VitaEnamic had the lowest TP values. For the 1 mm thickness groups, GC Cerasmart hadthe highest TP, whereas Vita Enamic had the lowest TP. For the 1.5 mm thicknessgroups, Lava Ultimate had the highest TP, whereas Vita Enamic had the lowest TP.For the 0.5 mm thickness groups, Vita Enamic, and GC Cerasmart had the highest andlowest OP, respectively. The OP values in the 1 mm thickness group of Vita Enamicgroups were higher than the GC Cerasmart and Lava Ultimate groups. The OP valuesin the 1.5 mm thickness group Lava Ultimate group were higher than the GCCerasmart and Vita Enamic groups. In all groups, the OP values showed an increasein parallel with the increase in thicknesses, in contrast, the TP values showed adecrease.

Özet

Amaç: Bu çalışmanın amacı, rezin matriks seramik blokların materyal çeşitlerinin ve kalınlıklarının translusensi parametrelerine (TP) ve opalesans parametrelerine (OP) etkilerini araştırmaktır. Gereç ve Yöntemler: Vita Enamic, Lava Ultimate ve GC Cerasmart rezin matriks seramik bloklarından oluşan 90 adet disk şeklindeki örnek (8 mm çap ve A2 renk, yüksek translusensi) 0,5 mm, 1 mm and 1,5 mm kalınlıklarında hazırlandı. TP ve OP değerlerini ölçmek için dental spektrofotometre (VITA Easyshade Advance) kullanıldı. Tüm örnekler beyaz ve siyah zemin üzerine yerleştirilip renk ölçümleri her örnek için 3 defa tekrarlandı ve L, a ve b değerleri hesaplandı. İstatistiksel analizler, çift yönlü varyans analizi (ANOVA) ve Tukey testleri ile yapıldı. Bulgular: 0,5 mm kalınlığındaki gruplarda, GC Cerasmart en yüksek, Vita Enamic ise en düşük TP değerleri göstermiştir.1 ve 1,5 mm kalınlığındaki gruplarda, GC Cerasmart ve Lava Ultimate yüksek TP değerleri gösterirken, Vita Enamic düşük TP değeri göstermiştir. OP değerleri ise 0,5 mm kalınlığındaki gruplarda, Vita Enamic’te en yüksekken GC Cerasmart’ta en düşük bulunmuştur. 1 mm kalınlığındaki gruplarda Lava Ultimate ve Vita Enamic, GC Cerasmart’a göre daha yüksek OP değerleri göstermiştir. 1,5 mm kalınlığındaki gruplarda, Lava Ultimate, GC Cerasmart ve Vita Enamic gruplarına göre daha yüksek OP değerleri göstermiştir. Tüm gruplarda, OP değerleri kalınlığın artmasıyla paralel bir artma gösterirken, tam tersine TP değerleri azalma göstermiştir. Sonuç: Rezin matriks seramiklerin çeşitleri ve kalınlıkları, materyallerin optik özelliklerini etkilemektedir.
