Investigation of The Effect on The Bond Strength Between Post And Dentine of Different Surface Kanal Dentini ve Fiberle Güçlendirilmiş Kompozit Post Yüzeyine Uygulanan Farklı Yüzey İşlemlerinin Post-Dentin Bağlantısına Etkisinin İncelenmesi

Abstract

Amaç: Çalışmanın amacı, kanal dentinine ve Fiberle güçlendirilmiş kompozit post yüzeyine uygulanan farklı yüzey işlemlerinin post- dentin bağlantısına etkisini incelemektir. Gereç ve Yöntemler: Çalışma için alt premolar dişler kullanıldı, Kontrol grubu dışında kanal dentin yüzeyi ve post yüzeyine değişik yüzey işlemleri (%35 fosforik asit, 50 µm aluminyum partikülleri, NAOCL, EDTA ve nd-YAG laser ) uygulandı. Buna göre örnekler her bir grupta 5 tane olmak üzere rastgele 11 gruba ayrıldı. Bu işlemlerden sonra dentin bağlayıcı ajanları kök kanalına uygulandı ve sonrasında 20 sn boyunca ışık uygulandı. Sonra resin kompozit, postların yüzeyine yerleştirildi ve post boşluğuna 2 mm. uzaktan 40 sn. ışıkla sertleştirildi. Tartışma ve Sonuç: Bütün örnekler test edilmeden önce 37 o C de distile suda bekletildi. Bağlantı gücünü test etmek için Çekme-sıkıştırma makinesi ile çekme testi yapıldı. Elde edilen veriler istatistiksel olarak değerlendirildi. Nd-YAG lazerin uygulandığı gruptaki örneklerin en yüksek bağlanma dayanımı gösterdiği görüldü
