Abstract

Aim: The aim of this study was to determinate the flexural strength values of different hybrid and packable composite resin materials after applied three-points bending test. Material and Methods: In study; five composite resins (four hybrid composite resins: Herculite-XRV, Tetric-Ceram, Valux-P, Filtek Z-250 and one packable composite resin: Filtek P-60) were used and five test groups were determinated (n=I0). Specimens were prepared at size of 2x2x25 mm. They were stored at distilled water for 24 hours at room temperature after polymerization and then three points bending test was applied to all specimens with Lloyd LRX Universal test machine according to ISO 10477. Data was determined with One-Way ANOVA and Duncan Multiple Comparison Test statistically using SPSS software computer programme (p<0.05). Results: In study; it was observed that, flexural strength of Valux-P, Filtek Z-250 and Filtek P-60 materials have shown difference than Herculite XRV and Tetric-Ceram materials and Valux-P, Filtek Z-250 and Filtek P-60 materials have provided higher values of flexural strength significantly (p<0.05). Conclusion: This in vitro study concluded that Valux-P and Filtek Z-250 hybrid composite materials and Filtek P-60 packable composite material have highly flexural strength and according to these results, each three materials have good physical material properties to prefer clinical using.

Özet

Amaç: Farklı lıibrid ve kondanse edilebilir kompozit vezin materyallerin, üç-nokta eğilme testi ile elde edilen eğilme direnci değerlerinin incelenmesidir. Gereç ve Yöntem: Çalışmada; Herculite-XRV, Tetric-Ceram, Valux-P, Filtek Z-250 olmak üzere 4 lıibrid ve Filtek P-60 olmak üzere 1 tepilebilir kompozit rezinden oluşan 5 kompozit rezin materyal kullanılmış ve 5 test grubu belirlenmiştir (ıı=10). 2x2x25 mm ebatlarında hazırlanan ve polimerizasyonıı takiben oda sıcaklığında 24 saat distile suda bekletilen örneklere, Lloyd LRX Universal test cihazı ile üç-nokta eğilme direnci testi uygulanmıştır. Testin uygulanması, İSO 10477 standartlarına göre yapılmıştır. Elde edilen veriler, SPSS software bilgisayar programı kullanılarak; Tek-Yönlü ANOVA ve Duncan Çoklu Karşılaştırma Testleri ile istatistiksel açıdan değerlendirilmiştir (p<0.05). Bulgular: Çalışmada; Valux-P, Filtek Z-250 ve Filtek P-60 materyallerinden elde edilen sonuçların; Herculile XRV ve Tetric-Ceram materyallerinden elde edilen sonuçlardan istatistiksel olarak farklı oldukları gözlenmiştir (p<0.05). Buna göre Valıa-P, Filtek Z-250 ve Filtek P-60 materyalleri, çalışmada belirgin olarak daha yüksek eğilme direnci değerleri sağlamışlardır. Sonuç: Mevcut çalışmadan elde edilen bu sonuçlar doğrultusunda, üç-nokta eğilme testi sırasında yüksek direnç değerleri sağlayabilen Va!ux-P, Filtek Z-250 lıibrid ve Filtek P-60 kondanse edilebilir kompozit materyallerinin, klinik kullanım amacıyla tercih edilebilecek düzeyde iyi fiziksel materyal özelliklerine sahip kompozit rezinler oldukları sonucuna varılmıştır.
