Amaç: Bu çalışmanın amacı farklı kalınlıklarda ve farklıyapıdaki tam seramik materyallerinin translusenstlik değerlerini incelemektir.Gereç ve Yöntem: Beş farklı seramikten (feldspatik, lösit ilegüçlendirilmiş, lityumdisilikat ile güçlendirilmiş,altyapı zirkonya,monolitik zirkonya) ve iki farklı kalınlıkta (0,5-1 mm) örneklerhazırlanmıştır. Her bir grup için örnek sayısı beş olarak saptanmıştır.Örneklerin kontrastlık oranlarını elde etmek için elde etmek içinspektrofotometreyle beyaz zemin (L*w) ve siyahzemin (L*b) üzerinde üçer adet ölçüm gerçekleştirilmiştir. Veriler iki yönlüvaryans analizi ile değerlendirilmiştir. Gruplar arasıkarşılaştırmalar için Tukey’s HSD testi kullanılmıştır. Bulgular: 0,5 mm kalınlıktaki gruplar kendi aralarındakarşılaştırıldığında feldspatik ve lösit ile güçlendirilmiş cam seramik dışındabütün gruplar arasında istatistiksel olarak anlamlıfarklılıklar görülmüştür. 1 mm kalınlığındaki gruplar kendi aralarındakarşılaştırıldığında altyapı zirkonya ve monolitik zirkonya dışında bütüngruplar arasında istatistiksel olarak anlamlı farklılık bulunmuştur.Sonuç: Kalınlık ve yapısal farklılıklar seramiğin translusensiözelliğini etkilemektedir.Anahtar Kelimeler: Tam seramik, translusensi, kontrastlıkoranıCOMPARISON OF TRANSLUCENCY VALUES OFALL CERAMIC MATERIALS WITH DIFFERENT STRUCTURES AND THICKNESSESABSTRACTAim: The aim of the studyis to evaluate the translucency of all ceramic materials with differentthicknesses and structures.Material and Methods: Specimenswith two different thicknesses (0.5-1 mm) were prepared from five differentceramic materials (feldspathic, leucite-reinforced, lithium disilicatereinforced, framework zirconia, monolithic zirconia). Each group contained fivespecimens. Three measurements were made with spectrophotometry to obtain thecontrast ratios of the materials over a white background (L*w) and a blackbackground (L*b). The data was analysed by two-way analysis of variance. Thegroups were compared by Tukey’s HSD test.Results: Groups which have athickness of 0.5 mm had statistically significant differences except feldspaticand leucite reinforced ceramic. Groups which have a thickness of 1 mm hadstatistically significant differences except framework zirconia and monolithiczirconia.Conclusion: Thicknessand structural differences affects the translucency feature of ceramic. Keywords: All ceramic, translucency,contrast ratio
