Abstract (2. Language): 
In deeper dentin, where the number of tubules is higher, the bond strength is lower. Remaining dentin thickness is claimed to be responsible for a great decrease in bond strength of adhesive systems, the purpose of mis in vitro study was to compare "the tensile bond strengths of resin composite to dentin in Black II cavities, mediated by two new bonding systems (One- Step and Clcarfil Liner Bond 2). The remaining dentin thickness (ROT) was also evaluated. A microtensile test was used for bond tests and no statistical difference was found between the two groups according to Mann Whitney-U Test and no correlation was found between the RDT and tensile bond strengths. Too many blisters were observed on the dentinal surfaces of One-Step group when the broken samples observed under SEM. The SEM observations indicated that in in vitro conditions, it is diffucuH to obtain appropriate dentinal surfaces for wet bonding.

Abstract (Original Language): 
Dentinin geçirgenliği, içerdiği tiibüllerin yapısı nedeni ite pulpaya yakın bölgelerde daha fazladır- Dentin yüzeyine bağlanmada, restoratif materyal vc pulpa arasında kalan dentin miktarının önemli olduğu, pulpa yüzeyine yaklaştıkça bağlanma dayanımlarında düşus " "'olduğu bildirilmiştir. Bu çalışmada, iki yeni nesil dentin bonding sistemin (One-Step vc Clearfil Liner Bond 2), Black II kavitelerde, gerilim kuvvetleri altında dentine bağlanma dayanımları incelenmiş ve kalan dentin kahilliğinin bağlanma dayanımlarına etkisi değerlendirilmiştir. Gerilim testleri bir mikrotensit test ite yapılmış ve sonuçlar Mantı Whitney-U ve Korelasyon testleri ile değerlendirilmiştir. Buna göre her iki materyal arasında bağlanma dayanımı açısından istalisüksel olarak önemli bir fark bulunamamış, kalan dentin kahnlığı ile bağlanma dayanımları arasında da yine istatistiksel olarak önemli bir ilişki gözleneni emiştir. Kırılma yüzeyleri SEM'de incelendiğinde ise, One Step grubunda, İaboratuvar şartlarında.^ ıslak bonding (wet bonding) sistemler için uygun nemli dentin yüzeyinin sağlanamadığı, bu nedenlede örneklerde aşın neme bağlı hava kabarcıkları olduğu gözlenmiştir,
