EVALUATION OF COLOR STABILITY OF CEROMERS AT DIFFERENT SOLUTIONS

Abstract

Restorative composites containing glass and quartz particles in the resin matrix, single-tooth restorations or prosthetic material used as veneer restorations. According to this new fiber reinforced composite materials to strengthen the structure of composites (FRC) and ceramics reinforced composite (Ceromer) to be divided into two main groups. This study ceromer coloring material different solutions, was carried out to evaluate the properties and color stability. In our study 5 mm diameter and 4 mm high ceromer cylindrical specimens were obtained. The samples were divided into five groups. Eight samples for each group were randomly selected. Color values of the prepared samples were recorded immediately. Then samples of each group were separately immersed in various solution (Solution 1: 990 ml saliva, Solution 2: 660 ml saliva + 330ml tea, Solution 3: 660 ml saliva + 330 ml coffee, Solution 4: 660 ml saliva + 330 ml Cola, Solution 5: 660 ml saliva + 330 ml fruit juice). Samples were immersed in solution 7, 15 and 30 days. Color values were measured and recorded. Color values are widely used for color analysis were determined by CIE color analysis system. Analysis of variance was used to evaluate the data. Different of drinks and waiting time was significantly higher (p <0.001) were statistically significant

SEROMERLERİN FARKLI SOLUSYONLARDAKİ RENK DEĞİŞİMLERİNİN İNCELENMESİ

Abstract

 Rezin matriks içerisinde cam ve kuartz partikülleri içeren restoratif kompozitler, tek diş restorasyonlarında veya protetik restorasyonlarda veneer materyali olarak kullanılırlar. Bu yeni kompozitler yapılarındaki güçlendirme materyallerine göre fiberle güçlendirilmiş kompozit (FRC) ve seramikle güçlendirilmiş kompozit (Ceromer) olmak üzere iki ana gruba ayrılırlar.

  Bu çalışma, seromer materyalinin farklı solüsyonlardaki renklenme özelliklerini ve renk stabilitesini değerlendirmek amacı ile yapılmıştır.

Çalışmada 5 mm çapında 4 mm yüksekliğinde hazırlanan toplam 40 seromer silindir örnek, her bir grupta rastgele seçilen sekiz örnek olacak şekilde beş gruba ayrılmıştır. Renk değerleri kaydedilen örnekler, farklı solüsyonlara (Solüsyon 1: 990 ml yapay tükürük, Solüsyon 2: 660 ml yapay tükürük + 330 ml çay, Solüsyon 3: 660 ml yapay  tükürük +330 ml  kahve, Solüsyon 4: 660 ml yapay  tükürük + 330 ml kola, Solüsyon 5: 660 ml yapay  tükürük + 330 ml meyve suyu) konulmuştur. Solüsyonlarda 7, 15 ve 30 gün bekletilen örneklerin renk değerleri ölçülmüş ve kaydedilmiştir. Renk değerleri renk analizi yapmak için yaygın olarak kullanılan CIE renk analiz sistemi ile saptanmıştır.

Verilerin değerlendirilmesi amacı ile varyans analizi kullanılmıştır. İçecek çeşidinin ve bekletme süresinin anlamlı olduğu (p<0.001) istatistiksel olarak saptanmıştır.
