Farklı içeceklerde bekletilen kompozit rezinlerin renk stabilitelerinin karşılaştırılması

Amaç: Bu çalışmanın amacı günlük hayatta sıkça tüketilen içeceklerde bekletilen farklı kompozit rezinlerin renk stabilitelerini değerlendirmektir. Gereç ve Yöntem: Altı farklı kompozit rezin grubundan (Filtek Silorane, Aelite Aesthetic Enamel, Quixfill, Ceram X Mono, Grandio, IntenS) disk şeklinde (15x2mm) 25’er adet örnek hazırlandı. Her bir kompozit grubunda hazırlanan örnekler 5 alt gruba ayrılarak (n=5) farklı tipteki solüsyonlarda (su, kahve, çay, kola ve kırmızı şarap) 37°C’ de 48 saat süresince bekletildi. Bütün gruplardaki kompozit örneklerin renk değerleri solüsyonlarda bekletilmeden önce ve bekletildikten sonra kolorimetre cihazı (Minolta CR-300) ile ölçüldü. Veriler CIE L*a*b* sistemine göre kaydedilerek renk farklılıkları (ΔE*) hesaplandı. Renk değişimlerinin istatistiksel analizi çift yönlü varyans analizi (Two-way ANOVA) ile yapılırken ortalamaların çoklu karşılaştırılması için Tukey HSD testi (α=.05) kullanıldı. Bulgular: Test edilen 6 farklı kompozit rezin için en düşük ΔE* değerleri su içerisinde bekletilen gruplarda tespit edilmiştir (p<0.05). En yüksek renk değişimi ise kırmızı şarap ve kahvede bekletilen gruplarda tespit edilmiştir (p<0.05). Restoratif materyaller karşılaştırıldığında Aelite Aesthetic Enamel, ve Filtek Silorane gruplarında belirgin olarak daha az renk değişimi gözlenmiştir (p<0.05). Sonuç: Kompozit rezinlerde oluşan renklenmelerin içeceğin tipi ve rezin kompozitin bileşimi ile ilgili olduğu tespit edilmiştir. Siloran esaslı kompozit rezinler dışsal renklenmelere karşı dirençlidir.

The comparison of color stability of composite resins after ımmersion in different drinks

Purpose: The purpose of this study was to evaluate the color stability of different composite resins upon exposure to different drinks which were highly consumed in daily life. Materials and methods: Twenty-five disc-shaped (15×2 mm) cylindrical specimens were prepared for each of 6 different composite resins (Filtek Silorane, Aelite Aesthetic Enamel, Quixfill, Ceram X Mono, Grandio, IntenS). The specimens of each composite resin groups were divided into 5 subgroups (n=5) for storage for 48 hours at 37°C in different types of solutions: water, coffee, tea, cola, and red wine. The color values of all groups were measured before and after exposure to different solutions with a colorimeter (Minolta CR-300). Data were recorded according to the CIE L*a*b* system and then color changes (ΔE*) were calculated. The statistical analysis of the color variation data included a 2way analysis of variance (ANOVA) and the means were compared by Tukey HSD test (α=.05). Results: For the 6 restorative materials tested, the lowest ΔE* values were observed in the water immersed group (p<0.05). The highest color differences were observed in the red wine and coffee immersed groups (p<0.05). When comparing the restorative materials, Aelite Aesthetic Enamel and Filtek Silorane demonstrated significantly showed less color change than the other composite groups (p<0.05). Conclusions: Discoloration of composite resins is based on the composition of the composite resins as well as the type of the drinks. Silorane-based composite resins are resistant to external discoloration.
