Universal adezivlerin iki tabaka uygulanmasının bağlanma performansına etkisi

Amaç: Bu çalışmanın amacı, universal adezivlerin iki tabaka uygulanmasının dentine bağlanma dayanımı üzerindeki etkisini değerlendirmektir. Gereç ve Yöntem: Yetmiş adet çürük içermeyen insan üçüncü azı dişi kullanıldı. Dişler rastgele yedi gruba ayrıldı (n = 10). Universal adezivler Single Bond Universal (3M Oral Care), Gluma Bond Universal (Heraeus Kulzer) ve Prime&Bond Universal (Dentsply) üreticinin talimatlarına göre ve iki tabaka halinde kullanıldı. Kontrol grubu olarak iki basamaklı kendinden asitli adeziv Clearfil SE Bond (Kuraray Noritake) kullanıldı. Kompozit üst yapılar orta-koronal oklüzal dentin yüzeylerine bağlandıktan sonra örnekler distile su içinde saklandı (37 °C/24 saat) ve mikro örneklere ayrıldı. Örnekler mikrogerilme bağlanma dayanımı testine (1,0 mm / dakika) tabi tutuldu. Başarısızlık tiplerinin analizi ışık mikroskobu ve taramalı elektron mikroskobu kullanılarak yapıldı. Veriler tek yönlü ANOVA ve Duncan testi ile analiz edildi (p=0,05). Bulgular: İki tabaka halinde uygulama, üç universal adezivin dentine bağlanma dayanımını arttırdı (p<0,05). Clearfil SE Bond, universal adezivler tek kat halinde uygulandığında universal adezivlere kıyasla daha yüksek bağlanma dayanımı değerleri gösterdi (p<0,05). Tek tabaka halinde uygulandığında, Prime&Bond Universal ile, Single Bond Universal ve Gluma Bond Universal'den daha yüksek bağlanma dayanımı değerleri elde edildi (p<0,05). Sonuç: İki tabaka uygulama, universal adezivlerin dentine bağlanma dayanımının arttırılmasında faydalı olmuştur. Clearfil SE Bond, universal adezivlerden daha iyi bağlanma dayanımı sonuçları göstermiştir.
