Abstract

Aim: Universal adhesives are widely used in restorative dentistry. The aim of this study was to evaluate the shear bond strength (SBS) of universal adhesives to dentin in different application modes.
Materials and Methods: The study utilized seven universal adhesives and one total-etch adhesive. The sixty-four extracted intact human molars used in the study were embedded in acrylic blocks to the enamel-cement junction. The occlusal surface was removed to expose the dentin surface. After applying self-etch and total-etch adhesives to the dentin, flowable composite (Clearfil Majesty Flow, Kuraray) was placed in a transparent mold (2.38 mm diameter and 2 mm height) and polymerized. After thermal aging (1000 cycles), a SBS test has been carried out on a universal testing machine. The fracture types formed on the surface of the teeth were examined under a microscope. Data were analyzed by two-way analysis of variance (ANOVA) test (p<0.05).
Results: SBS values of universal adhesives on dentin showed statistically significant differences according to adhesive and application mode (p<0.05). Total-etch application produced statistically higher SBS than self-etch application (p<0.05). The two-step universal adhesive (G2 Bond Universal) had the highest SBS in both the self-etch and total-etch application modes (p<0.05). When the bond surfaces of the universal adhesives were examined, fractures occurred most frequently in the adhesive type.
Conclusion: The use of universal adhesives in the total-etch mode results in greater bond strength to dentin tissue. Universal adhesive type influences bond strength.

Üniversal Adezivlerin Dentine Makaslama Bağ Dayanımının İncelenmesi: İn Vitro Çalışma

Abstract

Amaç: Üniversal adezivler restoratif diş hekimliğinde yaygın olarak kullanılmaktadır. Bu çalışmanın amacı, üniversal adezivlerin dentine makaslama bağlanma dayanımını farklı uygulama modlarında değerlendirmektir.
Gereç ve Yöntemler: Çalışmada 7 adet üniversal ve 1 adet total-etch adeziv kullanıldı. Çalışmada kullanılacak 64 adet çekilmiş sağlam insan molar dişi mine-sement sınırına kadar akrilik bloklara gömüldü. Dişler, dentin yüzeyini açığa çıkaracak şekilde okluzal yüzeyden aşındırıldı. Dentin dokusu üzerine adezivler self-etch ve total-etch modda uygulandıktan sonra şeffaf bir kalıp (2,38 mm çap ve 2 mm yükseklik) içerisinde akıcı kompozit (Clearfil Majesty Flow, Kuraray) konularak polimerize edildi. Termal yaşlandırma (1000 siklus) işleminden sonra üniversal test cihazında makaslama bağ dayanım testi yapıldı. Dişlerin yüzeyinde oluşan kırık tipleri mikroskop altında incelendi. Çalışmada veriler iki yönlü varyans analiz (ANOVA) testi kullanılarak değerlendirildi (p<0,05).
Bulgular: Üniversal adezivlerin dentin üzerindeki makaslama bağ dayanım değerleri adeziv ve uygulama modduna göre istatiksel anlamlı farklılıklar gösterdi (p<0,05). Total-etch uygulama self-etch uygulamadan istatiksel olarak daha fazla makaslama bağ dayanım gücü oluşturdu (p<0,05). İki aşamalı üniversal adeziv (G2 Bond Universal) self-etch ve total-etch uygulama modunda en fazla makaslama bağ dayanımı gösterdi (p<0,05). Üniversal adezivlerin bağlantı yüzeyleri incelendiğinde en fazla adeziv tipte kırık görüldü.
Sonuç: Üniversal adezivlerin total-etch modda kullanılması dentin dokusu üzerinde daha fazla bağlantı gücü oluşturmaktadır. Üniversal adeziv tipi bağlantı gücü üzerinde etkilidir.
