AB  - Aim: This study investigates the reliability of try-in pastes in determining the final color of zirconia laminate veneer restorations produced with varying thicknesses.Material and Methods: Phantom teeth were prepared in three thicknesses (0.5, 0.7, 1 mm) using depth gauge burs. The preparations were scanned with an intraoral scanner, and impressions were taken. Thirty resin die models were produced using a 3D printer. Zirconia laminate veneers were fabricated in three specified thicknesses. Initial color measurements (L, a, b values) of the veneers, applied to the die models with transparent petroleum jelly were taken. Color measurements were repeated using try-in paste after removing the petroleum jelly. The veneers were then roughened, ultrasonically cleaned, and ceramic primer applied. They were cemented with resin cement matched to the try-in paste color. Final color data were obtained using a spectrophotometer. Color change values were calculated from the L, a, b values, and data were compared using two-way ANOVA and Bonferroni Test.Results: The thickness of the material did not influence color change, whereas the use of try-in paste or resin cement resulted in significant color differences.Conclusion: The study findings indicate that try-in pastes are not reliable indicators of the final restoration color. It is crucial to consider that resin cement can substantially alter the color of zirconia laminate veneers when determining the final shade.

N2  - Amaç: Bu çalışma, farklı kalınlıklarda üretilen zirkonya laminate veneer restorasyonlarının sonuç renginin belirlenmesinde deneme pastalarının güvenilirliğinin araştırmaktadır.Gereç ve Yöntemler: Fantom dişler derinlik ölçer frezler ile 3 farklı kalınlıkta (0,5, 0,7, 1 mm) prepare edilmiştir. Preparasyonlar bir ağıziçi tarayıcı ile taranarak ölçüsü alınmış ve 3 boyutlu yazıcı yardımı ile toplamda 30 adet rezin day model üretilmiştir. Zirkonya laminate veneerler, bu day modeller üzerine 3 farklı kalınlıkta üretilmiştir. Şeffaf renk vazelin ile day modele tutturulan laminate veneerlerin başlangıç renk (L, a, b değerleri) ölçümleri yapılmıştır. Ardından vazelin temizlenerek deneme pastası ile renk ölçümleri tekrarlanmıştır. Deneme pastası ile renk ölçümlerinin ardından, laminate veneerler 110 μm çaplı silika modifiye alüminyum oksit partikülleri ile pürüzlendirilmiş, ultrasonik olarak temizlenmiş ve veneerlere seramik primer uygulanmıştır. Laminate veneerler deneme pastası ile eş renkteki siman ile yapıştırılmıştır. Simantasyonun ardından spektrofotometre ile restorasyonun nihai renk verileri elde edilmiştir. Elde edilen L, a, b değerlerinden renk değişim değerleri hesaplanmış ve iki yönlü ANOVA ve Bonferroni Testi ile veriler karşılaştırılmıştır.Bulgular: Materyal kalınlığı renk değişimine etki etmezken, deneme pastası veya rezin siman kullanımı önemli renk farklılıklarına yol açmıştır.Sonuç: Çalışma bulguları, deneme pastalarının nihai restorasyon renginin güvenilir göstergeleri olmadığını ortaya koymaktadır. Nihai tonu belirlerken reçineli simanın zirkonya lamina kaplamalarının rengini önemli ölçüde değiştirebileceği dikkate alınmalıdır.
