Abstract

Amaç: Bu çalışmanın amacı; sodyum hipoklorit ve hipokloröz asit solüsyonları kullanılarak smear tabakası deproteinizasyonunun, kendinden adezivli rezin simanın dentine bağlanma dayanımı üzerindeki etkisinin incelenmesidir.
Gereç ve Yöntem: Çalışmada toplam 56 adet çekilmiş insan büyük azı dişi kullanılmıştır. Dişlerin dentin yüzeyleri üzerinde aşındırıcılarla üniform bir şekilde smear tabakası oluşturulmuştur. Herhangi bir okside edici ajan uygulanmayan (kontrol), sodyum hipoklorit 30 sn uygulanan (NaOCl), hipokloröz asit 15 sn (HOCl-15) ve 30 sn uygulanan (HOCl-30) grup olmak üzere 4 farklı deney grubu oluşturulmuştur. Hazırlanmış kompozit bloklar, dentin yüzeylerine kendinden adezivli rezin siman (TotalCem, Itena, Paris, Fransa) ile simante edilmiştir. Örneklere üniversal test cihazında makaslama bağlanma dayanımı testi uygulanmıştır. Dentin yüzeyleri taramalı elektron mikroskobu (FE-SEM, Mira 3 XMU, Tescan, Brno, Çek Cumhuriyeti) ile incelenmiştir. İstatistiksel analizler için, Tek Yönlü Varyans Analizi (ANOVA) ve post-hoc Tukey HSD testleri kullanılmıştır (p˂0.05).
Bulgular: HOCl-15 grubunda bağlanma dayanımının diğer çalışma gruplarından anlamlı olarak daha yüksek olduğu belirlenmiştir (p˂0.05).
Sonuç: HOCl ile smear tabakası deproteinizasyonunun diş ile kendinden adezivli rezin siman arasındaki bağlanma dayanımını arttırıcı etkisi olabileceği düşünülmektedir.

Effect of Smear Layer Deproteinization on Bond Strength of Self-Adhesive Resin Cement to Dentin

Abstract

Aim: The aim of this study is to examine the effect of smear layer deproteinization using sodium hypochlorite and hypochlorous acid solutions on the bond strength of self-adhesive resin cement to dentin.
Materials and Method: A total of 56 extracted human molars were used in the study. A uniform smear layer was formed with abrasives on the dentinal surfaces of the teeth. Four different experimental groups were formed: no oxidizing agent was applied (control), sodium hypochlorite was applied for 30 seconds (NaOCl), hypochlorous acid was applied for 15 seconds (HOCl-15) and 30 seconds were applied (HOCl-30). Prepared composite blocks were cemented to dentin surfaces with self-adhesive resin cement (TotalCem, Itena, Paris, France). Shear bond strength test was applied to the samples in a universal testing device. Dentin surfaces were examined by scanning electron microscopy (FE-SEM, Mira 3 XMU, Tescan, Brno, Czech Republic). One-way Analysis of Variance (ANOVA) and post-hoc Tukey HSD tests were used for statistical analysis (p˂0.05).
Results: It was determined that the bond strength in the HOCl-15 group was significantly higher than the other study groups (p˂0.05).
Conclusion: Deproteinization of the smear layer with HOCl is thought to increase the bond strength between the tooth and the self-adhesive resin cement.
