Abstract :Amaç: Estetik restoratif CAD/CAM kompoziti insert ignore into journalissuearticles values(Lava Ulti- mate; 3M ESPE, St.Paul, ABD); ve hibrit seramik materya- linin insert ignore into journalissuearticles values(Vita Enamic, Vita Zahnfabrik, Almanya); translüsensi ve renk stabilitesi hakkında yeterli bilgi bulunmamaktadır. Bu çalışmanın amacı, restorative CAD/CAM materyallerinin translüsensi ve renk stabilitesini araştırmaktır. Gereç ve Yöntem: Onar örnekten oluşan dört grup, 1 mm kalınlığında hibrit seramik ve rezin nanoseramik kompozit rezin monolitik bloklardan hazırlandı. Test edilen tüm materyaller için 2M2, yüksek translüsensili bloklar seçildi. Yüzey bitirmelerinde Lava Ultimate örnekler için Sof-Lex insert ignore into journalissuearticles values( 3M ESPE, St.Paul, ABD); diskler, Vita Enamic için Vita Enamic polishing set insert ignore into journalissuearticles values(Vita Enamic, Vita Zahnfabrik, Almanya); kullanıldı. Örneklerin her iki yüzüne de polisaj uygulandı. Translüsensi parametresi ve renk farklılıkları, örnekler 48 saat kahve solüsyonunda bekletilmeden önce ve sonrasında CIE L*a*b* sisteminde spektrofotometre insert ignore into journalissuearticles values(Vita Easy Shade, Vita Zahnfabrik, Almanya); ile ölçüldü. Veriler Mann-Whitney U testi ile incelendi insert ignore into journalissuearticles values(p<.05);. Bulgular: Lava ve Vita Enamic kontrol grupları arasında anlamlı fark görülmedi insert ignore into journalissuearticles values(p=1);. Kahve solüsyonunda bekletilme sonrasında CAD/CAM materyallerin translüsensi parametresi değerleri azalırken ∆E renk farklılıklarında artış gözlendi. Kahvede bekletilme sonrasında Lava Ultimate insert ignore into journalissuearticles values(10.9±1);, Vita Enamic’den insert ignore into journalissuearticles values(9.1±0.7); daha yüksek translüsensi parametresi değeri sergiledi. Ayrıca kahvede bekletilen Lava Ultimate örneklerin ∆E değeri insert ignore into journalissuearticles values(∆E=3.4); Vita Enamic’den insert ignore into journalissuearticles values(∆E=1.8); daha fazla ve eşik değerin insert ignore into journalissuearticles values(∆E=2.7); üstünde ölçüldü. Sonuç: Çalışmamızda Lava Ultimate daha yüksek translü- sensi değeri sergiledi ancak daha fazla renk değişimi gösterdi. Anahtar Kelimeler: Translüsensi, Renk Stabilitesi, CAD/CAM EVALUATION OF TRANSLUCENCY AND COLOR STABILITY OF ESTHETIC CAD/CAM RESTORATIVE MATERIALS ABSTRACT Aim: Adequately information is not available about the translucency and color stability of esthetic restorative CAD/CAM composite insert ignore into journalissuearticles values(LAVA Ultimate, 3M ESPE, StPaul, USA); and hybrid ceramic material insert ignore into journalissuearticles values(VITA Enamic, Vita Zahnfabrik, Germany);. The purpose of this study was to investigate the translucency and color stability of restorative CAD/CAM materials. Material and Methods: Four groups consist of 10 specimens, were prepared with 1 mm thickness of hybrid ceramic and resin nano ceramic composite resin monolithic blocks. 2M2 high translucent blocks were chosen for all tested materials.   Surface finishing was performed with Sof-Lex insert ignore into journalissuearticles values(3M ESPE, StPaul, USA); discs for Lava Ultimate specimens and Vita Enamic polishing set insert ignore into journalissuearticles values(VITA Enamic, Vita Zahnfabrik, Germany); was used for Vita Enamic. The polishing procedures were performed on both sides of the specimens. Translucency parameter and color differences were measured in the CIE L*a*b* system by spectrophotometer insert ignore into journalissuearticles values(Vita Easy Shade, Vita Zahnfabrik, Germany); before and after 48 hours of immersion in a coffee solution. Data were analyzed with Mann-Whitney U test insert ignore into journalissuearticles values(p<.05);. Results: There was no significant difference between the Lava control group and Vita Enamic control group insert ignore into journalissuearticles values(p=1);. After immersion of coffee solution, translucency parameter values of CAD/CAM materials were decreased and increased ∆E color differences were observed.   Significant differences were found among coffee groups for all specimens tested insert ignore into journalissuearticles values(p<.001);. After coffee immersion, Lava Ultimate showed higher translucency parameter value insert ignore into journalissuearticles values(10.9±1); than Vita Enamic insert ignore into journalissuearticles values(9.1±0.7);. Also, ∆E values of Lava Ultimate insert ignore into journalissuearticles values(∆E=3.4); specimens which stored in coffee solution were higher than Vita Enamic insert ignore into journalissuearticles values(∆E=1.8);, and were over than threshold ∆E insert ignore into journalissuearticles values(∆E=2.7);. Conclusion: Lava Ultimate showed more translucency parameter value, but also showed more staining in our study. Keywords: Translucency; Color Stability; CAD/CAM
