Mekanik Cilalama, Renklenme ve Profilaktik Cilalama Sonrası BDT/BDÜ Materyallerinin Renk Değişimi ve Translusensi Değerlerinin İncelenmesi

Giriş ve Amaç: Bu çalışmanın amacı, mekanik polisaj, kahve ile renklendirme ve profilaktik polisaj prosedürlerine tabi tutulduktansonra bilgisayar destekli tasarım ve bilgisayar destekli (BDT/BDÜ) bloklardan elde edilen örneklerin translusensi ve renk değişiminideğerlendirmektir. Yöntem ve Gereçler: Her iki bloktan (Cerasmart A2-HT; GC, Initial-LRF, A2-HT: GC) toplam 26 adet örnek (n= 13) elde edildi.Örneklerin renk değişimi ve translusensi değerleri mekanik cilalama, kahve ile renklendirme ve profilaktik cilalama prosedürlerinetabi tutulduktan sonra spektrofotometre ile ölçüldü. Veriler Shapiro-Wilk normallik testi ile analiz edildi. Translusensi ve renk değişimdeğerleri Friedman testi ile istatistiksel olarak değerlendirildi. Translusensi ve renk değişimi açısından Cerasmart ve Initial-LRFarasındaki istatistiksel farkı belirlemek için ise Mann Whitney-U testi kullanıldı (α=.05). Bulgular: Cerasmart ilk ölçümde ve mekanik parlatma sonrası Initial-LRF’e göre istatiksel olarak anlamlı derecede daha translusentbulunmuştur (p

Color Stability and Translucency of Two CAD-CAMRestorative Materials Subjected To Mechanical Polishing,Staining, and Prophylactic Paste Polishing Procedures

Introduction: The aim of this study is to evaluate the translucency and color change of two computer-aided design and computer aided manufacturing (CAD/CAM) blocks after subjected to mechanic polishing, coffee staining, and prophylactic paste polishing procedures. Methods: 26 specimens (n=13) were obtained from each CAD/CAM block (Cerasmart A2-HT; GC, Initial-LRF, A2-HT: GC). Colorchange values were evaluated after subjected to mechanic polishing, coffee staining, and prophylactic polishing procedures. Datawere analyzed by a Shapiro-Wilk normality test and the translucency and color change values were evaluated statistically withFriedman test. Mann Whitney-U test was used to determine the statistical significance between the Cerasmart and Initial-LRF interms of translucency and color change (α=.05). Results: For baseline measurements and after mechanic polishing measurement, the mean translucency value of the Cerasmartwas significantly higher than Initial-LRF (p
