ÖZET
 Amaç: Bu çalışmanın amacı, farklı sertleşme mekanizmasına sahip kaide materyallerinin mikrogerilim bağlanma dayanımlarını [microtensile bond strengths (μTBS)] karşılaştırmaktır. Gereç ve Yöntemler: Bu çalışmada rezin modifiye cam iyonomer (Fuji II LC), yüksek viskoziteli cam iyonomer siman (EQUIA Forte Fil), akışkan fiberle güçlendirilmiş kompozit (everX Flow), biyocam ile güçlendirilmiş cam iyonomer siman-biyoaktif kompozit (ACTIVA BioACTIVE- Restorative) ve universal adeziv ajan (Single Bond Universal) kullanılmıştır. Universal adeziv self-etch modunda kullanılmıştır. Toplam 8 insan azı dişi kullanılarak her bir dişten 5 çubuk; toplamda 40 çubuk elde edilmiştir (n=10). Her bir örnek universal test cihazında μTBS testine tabi tutulmuştur. Gruplardaki materyal, dentin arayüzü ve başarısızlık analizleri taramalı elektron mikroskobu ile değerlendirilmiştir. Bulgular: Verileri değerlendirmek için tek yönlü varyans analizi yapıldı ve analiz sonucunda farklılık gösteren grupları bulmak için Tukey testi kullanıldı. İstatistiksel anlamlılık düzeyi p<0,05 olarak alındı. μTBS değerleri incelendiğinde istatistiksel olarak anlamlı en düşük değer EQUIA Forte Fil grubunda, en yüksek değer ise everX Flow grubunda gözlendi (p<0,05). Çalışmada kullandığımız tüm kaide materyallerinde koheziv ve karışık kırık tipleri daha çok görüldü. Sonuç: En yüksek μTBS değerlerine sahip olan akışkan fiberle güçlendirilmiş kompozit grubu diğer materyallere kıyasla daha iyi bir bağlanma sağlayarak klinik başarının artmasını sağlayabilir.

ABSTRACT
 Objective: The aim of this study is to compare the microtensile bond strengths (μTBS) of base materials with different setting mechanisms. Material and Methods: In this study, a resin modified glass ionomer (Fuji II LC), a high viscosity glass ionomer cement (EQUIA Forte Fil), a flowable fiber reinforced composite (everX Flow), a bioglass-reinforced glass ionomer cement-Bioactive Composite (ACTIVA BioACTIVE- Restorative) and a universal adhesive agent (Single Bond Universal) were used. Universal adhesive was used in self-etch mode. A total of eight human molars were used, 5 rods from each tooth; 40 rods in total were obtained (n=10). Each sample was tested with μTBS on a universal testing device. The material-dentin interface and fracture types in the groups were evaluated with scanning electron microscope. Results: One-way analysis of variance analysis was performed to evaluate the data and Tukey test was used in pairwise comparisons. Statistical significance level was taken as p<0.05. When the μTBS values were examined, the lowest statistically significant value was observed in the EQUIA Forte Fil group and the highest value was observed in the everX Flow group (p<0.05). Cohesive and mixed fracture types were seen more frequently in all restorative materials used in the study. Conclusion: The flowable fiber reinforced composite group with the highest μTBS values can provide better bonding compared to other materials, thus increasing clinical success.
