Aim: The aim of this in vitro study was to assess the bond strength of three different self-adhesive resin cements on the post and dentin surface.
Material and Methods: In the present study, 15 extracted human maxillary canine teeth with single and straight roots were used. After the clinical crowns were removed from cemento-enamal junction, root canals were prepared with Reciproc R25 (VDW GmbH, Munich, Germany) files. The smear layer of roots were removed using 17% EDTA followed by 5.25% NaOCl and distillate water. Then all the root canals were obturated with lateral compaction technique using epoxy resin based sealer and gutta-percha. Then post space was prepared. The roots were then randomly divided into three groups according to resin cements. Fiber posts was cemented, using three different resin cement : Bifix SE (Voco GmbH,Cuxhaven, Germany), Breeze (Pentron,Wallingford,USA) , RelyX U 200 (3M ESPE,Neuss,Germany). The roots were sliced to 1mm-thick horizontal sections from the coronal and mid thirds (n: 5 root 4 slice = 20 specimen), and the push-out bond strength test applied. The data was calculated as MPa and statistically analyzed using one-way ANOVA and post-hoc Tukey test.
Results: There was no statistically significant difference between the Bifix SE, and the Breeze. There was a statistically significant difference between RelyX U 200 and the other resin cements.
Conclusion: The toughest of three tested resin cement was RelyX U 200 in comparison to push out bond strength. There was no difference between the bond strengths of Bifix SE and Breeze.

Üç Farklı Self-Adeziv Rezin Simanın Bağlanma Dayanımlarının Karşılaştırılması

Öz

Amaç: Bu in vitro çalışmanın amacı, üç farklı self-adeziv rezin simanın post ve dentin yüzeyine karşı bağlanma dayanımlarını push out test yöntemi ile değerlendirmektir.
Gereç ve Yöntem: Bu in vitro çalışmada tek köklü ve tek kanallı 15 adet üst çene kesici dişleri kullanıldı. Kronlar mine sement sınırından uzaklaştırıldıktan sonra kök kanalları Reciproc R25 eğelerle (VDW GmbH, Munich, Germany) genişletildi. Kanal dolumu öncesinde smear tabakası % 17 EDTA akabinde % 5,25 NaOCl ve distile su kullanılarak uzaklaştırıldı. Kök kanalları lateral kompaksiyon tekniği ile epoksi rezin içerikli kanal patı ve güta-perka kullanılarak dolduruldu. Daha sonra post boşlukları hazırlandı. Kökler, kullanılan rezin simana göre rastgele 3 gruba ayrıldı (n=5). Fiber postlar, üç farklı rezin siman kullanılarak simante edildi: Bifix SE (Voco GmbH, Cuxhaven, Germany), Breeze (Pentron, Wallingford, USA) ve RelyX U 200 (3M ESPE, Neuss, Germany). Bütün köklerin koronal ve orta üçlü kısmından 1 mm kalınlığında horizontal kesitler alındı (n: 5 kök * 4 kesit = 20 örnek) ve push out bağlanma dayanımı testi uygulandı. Bütün veriler MPa'a çevrildi ve istatistiksel analizler tek yönlü ANOVA ve post hoc Tukey testleri kullanılarak yapıldı.
Bulgular: Bifix SE ve Breeze arasında istatiksel olarak anlamlı bir fark bulunmazken, Rely X U 200 ve diğer rezin simanlar arasında istatiksel olarak anlamlı fark bulundu.
Sonuç: Test edilen üç rezin siman arasında bağlanma dayanımı açısından en dayanıklı olanı RelyX U 200 idi. Bifix SE ve Breeze arasında bağlanma dayanımları arasında fark yoktur.
