Abstract

Amaç: Bu çalışmanın amacı polietereterketon (PEEK) materyalinin veneerlenmesinde kullanılan tek renkli kompozitlerin yaşlandırma sonrası renk ve translusensi değişimlerinin değerlendirilmesidir.
Gereç ve Yöntemler: 3 adet farklı kimyasal yapıya sahip tek renkli kompozit ve 1 adet geleneksel kompozit rezin PEEK materyali üzerine 2 mm kalınlığında uygulandı (N=40, n=10). Her örneğin L, a, b renk değerlerinin ölçümü örneğin merkezinden olacak şekilde siyah, gri ve beyaz fon üzerinde spektrofotometre ile 3 kere yapıldı ve bu ölçümlerin ortalaması kaydedildi. Örnekler 5-55°C’de 5000 devir termal yaşlandırmaya tabii tutuldu. Yaşlandırma sonrası renk ölçümleri aynı şekilde tekrarlandı. Kompozit rezin örneklerin renk değişimleri (ΔE00) ve translusensi parametresi (ΔTP00) yaşlandırma öncesi ve sonrasında CIEDE 2000 renk formülleri kullanılarak belirlendi. Elde edilen veriler tek yönlü varyans analizi ve Tukey HSD testi ile istatistiksel analize tabii tutuldu (p<0,05).
Bulgular: Çalışmanın sonucunda tüm kompozit rezin materyallerinin renk değişimi klinik olarak kabul edilebilir sınırın (ΔE=1,8) altında bulundu. En az renk değişimi geleneksel kompozit grubunda gözlendi ve diğer gruplar ile arasında istatistiksel olarak anlamlı fark bulundu (p<0,05). Tek renkli kompozit materyallerinin translusensi değişimi geleneksel kompozit rezinden istatistiksel olarak daha düşük bulundu (p<0,05).
Sonuç: Bu çalışmanın sonuçları PEEK materyaline uygulanan direkt veneerleme işlemlerinde, tek renkli kompozit rezinlerin geleneksel kompozitlere optik açıdan bir alternatif olarak kullanılabileceğini göstermektedir.

Evaluation of Color and Translucency Changes of PEEK Material Veneered with Single-Shade Composite Resins

Abstract

Aim: The aim of this study was to evaluate the color and translucency changes of single-shade composites used in veneering polyetheretherketone (PEEK) material after aging.
Materials and Methods: 3 single-shade composites with different chemical structures and 1 conventional composite resin were applied on the PEEK material with a thickness of 2 mm (N=40, n=10). L, a, and b color coordinates of each specimen were measured three times with a spectrophotometer on a black, gray, and white background from the center of the specimen, and the average of these measurements was recorded. The specimens were subjected to 5000 cycles of thermal aging at 5-55°C. After aging, color measurements were repeated. Color changes (ΔE00) and translucency parameters (ΔTP00) of composite resin specimens were determined before and after aging using CIEDE 2000 color formulas. The data obtained were analyzed by one-way analysis of variance and Tukey HSD test (p<0.05).
Results: As a result of the study, the color change of all composite resin materials was found to be below the clinically acceptable limit (ΔE = 1.8). The lowest color change was observed in the traditional composite group, and a statistically significant difference was found between the other groups (p<0.05). The translucency change of single-shade composite materials was found to be statistically lower than that of conventional composite resin (p<0.05).
Conclusion: This study's results show that single-shade composite resins can be used as an optical alternative to traditional composites in direct veneering of the PEEK material.
