FARKLI İÇECEKLERDE BEKLETİLEN ORMOSER VE DİMETAKRİLAT-ESASLI KOMPOZİT REZİNLERİN RENK STABİLİTELERİNİN KARŞILAŞTIRILMASI

Amaç: Bu çalışmanın amacı belirli sürelerde farklı içeceklerde bekletilen organik modifiye seramik (ormoser) ve dimetakrilat-esaslı kompozit rezinlerin renk stabilitelerinin karşılaştırılmasıdır. Gereç ve yöntem: Bu çalışma için iki farklı visközitede ormoser-esaslı kompozit rezinler (Admira, Admira Flow) ve iki farklı dimetakilat-esaslı kompozit rezin (Valux Plus, Filtek Z250) kullanıldı. Her bir kompozitten 2 mm kalınlığında ve 8 mm çapında 20 adet örnek hazırlandı. Rastgele 4 gruba ayrılan örnekler üç farklı solüsyonda (kahve, pH 5,5; kola, pH 2,51 ve kırmızı şarap, pH 3,28) ve kontrol grubu olarak distile suda (pH:6,7) bekletildi (n=5). Renk ölçümleri, örnekler solüsyonlarda bekletilmeden önce ve bekletildikten 1, 7, 15 ve 30 gün sonra spektrofotometre ile yapıldı ve ΔE değerleri hesaplandı. Verilerin istatistiksel analizinde tek yönlü ANOVA ve Tukey LSD çoklu karşılaştırma testi kullanıldı. İstatistiksel anlamlılık düzeyi p<0.05 olarak alındı. Bulgular: Birinci gün sonunda yalnızca kırmızı şarapta bekletilen Valux Plus ve Filtek Z250 örneklerinde ΔE>3,3 bulunurken (p<0,05), 30 gün sonunda tüm örneklerde ΔE>3,3 bulundu. Tüm kompozitlerde en yüksek renk farklılıkları kırmızı şarapta bekletilen örneklerde görülürken (p<0,05), en yüksek ortalama renk farklılıkları Filtek 250 örneklerinde tespit edildi. Sonuçlar: Çalışmada kullanılan kompozit rezinlerin farklı içecekler karşısında renk değişimine hassas olduğu bulunmuş, ormoser-esaslı kompozit rezinler dışsal renklenmelere karşı daha dirençli bulunmuştur.

Materials and method: Two different ormocer-based composite resin (Admira, Admira Flow) with different viscosity and two dimethacrylate-based composite resin (Valux Plus, Filtek Z250) were used in this study. Twenty composite resin discs (8 mm x 2 mm) were prepared from each material. Specimens were randomly divided into 4 groups and were immersed in three staining solutions (coffee pH 5,5, cola pH 2,51, red wine pH 3,28) and distilled water for control group (n=5). Color changes were measured with a spectrophotometer at baseline and after 1, 7, 15 and 30 days of immersion and ΔE values were calculated. Data were analyzed by using one-way ANOVA and post-hoc Tukey LSD. A p-value <0.05 was considered statistically significant. Results: At the end of the first day, only in Valux Plus and Filtek Z250 samples immersed in red wine showed a ΔE value > 3.3, while at the end of 30 days in all samples ΔE was > 3.3. Among all drinks tested, maximal color change was caused by red wine (p<0.05). The highest color differences were calculated in Filtek Z250 samples (p<0,05). Conclusions: It can be concluded that the tested composite resin materials were susceptible to staining with different drinks and Ormocer-based composite resins are more resistant to external discolorations. Key words: Ormocer, Dimethacrylate-based composite, Color stability
