ABSTRACTPurpose: The purpose of this in vitro study was to determine how pretreatment with desensitizers affects micro-tensile bond strength between dentin and self-etch resin cement (SEC).Materials and Methods: The occlusal surfaces of extracted teeth were abraded with a diamond bur to the dentin layer and divided into 5 equal groups (n = 20); G1- control (no desensitizer, only Clearfil aesthetic resin cement (CEC); G2-Gluma and CEC; G3-Bi-fluorid 12 and CEC; G4-FGM desensitizer and CEC; G5- D/Sense Crystal and CEC. Resin cement layers were added to a depth of 8 mm in the control group, and desensitizer was applied to the surfaces before resin cement application in the other experimental groups. A specimen from each group was examined with scanning electron microscopy. The specimens were sectioned to be 1 mm2 perpendicular to the adhesive layer, and the microtensile test was applied. According to the results of the post hoc Tamhane test, there was a significant difference. (p<0.05).Results: Only the Gluma desensitizer had a significantly lower bond strength value when compared with the other desensitizers and the control group. Conclusions: While dentin with oxalate, fluoride, and strontium chloride-potassium nitrate contamination did not affect the bonding strength of SEC, dentin contamination with glutaraldehyde/HEMA had a negative effect. Keywords. Desensitizer, self-etch resin cement, microtensile bond strength.ÖZETAmaç: Bu in vitro çalışmanın amacı, dentine hassasiyet giderici ajan uygulamasının, self-etch rezin simanın (SEC) mikrogerilim bağlanma dayanımını nasıl etkilediğini araştırmaktır. Gereç ve Yöntem: Çekilmiş dişlerin oklüzal yüzleri elmas frez ile dentin tabakasına kadar aşındırıldı ve 5 eşit gruba ayrıldı (n = 20); G1- kontrol (hassasiyet giderici ajan kullanılmadı, sadece Clearfil estetik rezin siman (CEC); G2-Gluma ve CEC; G3-Bi-fluorid 12 ve CEC; G4-FGM ve CEC; G5-D/Sense Crystal ve CEC. Kontrol grubunda, dentin üzerine 8 mm yüksekliğinde rezin siman tabakası eklendi ve diğer deney gruplarına rezin simandan önce dentin hassasiyet giderici ajanlar uygulandı. Her gruptan bir örnek taramalı elektron mikroskobu ile incelendi. Örnekler dentin-siman bağlantısına dik olarak 1 mm2 olacak şekilde kesildi ve mikrogerilim bağlanma dayanımı ölçüldü. Post-hoc Tamhane testinin sonuçlarına göre anlamlı bir fark vardı (p <0.05). Bulgular: Dentin hassasiyet giderici ajanlar arasında sadece Gluma, diğer gruplar ve kontrol grubu ile karşılaştırıldığında anlamlı şekilde daha düşük bir bağlanma dayanımına sahipti. Sonuç: Dentin üzerine oksalat, florür ve stronsiyum klorür-potasyum nitrat uygulaması, SEC ile arasındaki bağlanma dayanımını etkilemese de, glutaraldehit/HEMA uygulaması olumsuz etkilemiştir. Anahtar kelimeler: Hassasiyet giderici ajan; Self-etch rezin siman; Mikrogerilim bağlanma testi
