Abstract

Aim: The purpose of this study was to investigate the influence of residual endodontic sealers on the adhesion of post luting cements. For hence, dentinal tubule penetration and bonding ability of three different self-adhesive resin cements was compared. Panavia SA; Kuraray, Tokyo, Japan. Relyx U200; 3M ESPE, Seefeld, Germany. Maxcem Elite; Kerr, CA, USA Material and Method: 180 mandibular second premolar teeth roots were used. 45 roots which were instrumented and obturated with gutta-percha and AH Plus sealer which were labeled with 0.1% fluorescein dye. Forty-five roots were only instrumented with ProTaper, but left not-filled. The teeth were divided into two main groups: root canal filling FR and no root canal filling NFR . Then, these roots were cemented with three different self-adhesive resin cements.The specimens were divided into 6 groups.Group 1: Filled root FR / Panavia SA Group 2: Not-filled root NFR / Panavia SA; Group 3:FR/RelyX U200Group 4: NFT/RelyX U200Group 5: FR/Maxcem EliteGroup 6: NFR/Maxcem Elite. Before the insertion of the posts, cement was labeled with Rhodamin B. After cementation process of the fiber posts, the specimens were cross sectioned and the slices were submitted to the push-out test and dentin tubule penetration evaluation of the cements using confocal laser scanning microscopy. Results: FR/Maxcem Elite cement group presented the lowest bond strength value to dentin in the cervical third P < .05 . The dentinal tubule penetration area was higher in the NFR specimens compared to the FR in the Panavia SA and Rely X U 200 groups p=0.024, p=0.047 . Panavia SA group yielded the highest dentinal tubule penetration percentage compared to the other groups. There was no statistically significant difference between the three cements regarding penetration depth p>0.05 . Conclusion: The NFR groups showed better dentin tubule penetration values than FR groups

Post Yapıştırma Simanlarının Bağlanma Dayanımı ve Dentin Tübül Penetrasyonun Değerlendirilmesi

Abstract

Amaç: Bu çalışmanın amacı, rezidüel kök kanal patının post yapıştırma simanlarının adezyonu üzerindeki etkisini araştırmaktır. Bu amaçla post yapıştırılmasında kullanılan üç farklı self adeziv rezin simanın Panavia SA; Kuraray, Japonya. Relyx U200; 3M ESPE, Almanya. Maxcem Elite; Kerr, ABD dentin tübül penetrasyonu ve push out testi yapılarak dentine bağlanma yeteneği karşılaştırılmıştır. Gereç ve Yöntem: 180 adet alt çene küçük azı diş kökü kullanıldı. 45 kök enstrümante edildi ve % 0,1 fluoesein boya ile etiketlenmiş AH Plus ve gutta perka ile dolduruldu. 45 adet kök ProTaper Universal ile prepare edildi. Dişler öncelikle kanal dolgusu yapılan KD+ ve kanal dolgusu yapılmayan KD- diye 2 ana gruba ayrıldı. Daha sonra bu köklere üç farklı self adeziv rezin siman ile post uygulandı. Örnekler 6 gruba ayrıldı. Grup 1: Kanal Dolgusu yapılan KD+ / Panavia SA rezin siman Grup 2:Kanal Dolgusu yapılmayan KD- / Panavia SA rezin siman Grup 3: KD+/ RelyX U200 rezin siman Grup 4: KD-/ RelyX U200 rezin siman Grup 5: KD+/ Maxcem Elite rezin siman Grup 6: KD-/ Maxcem Elite rezin siman Postların yerleştirilmesinden önce simanlar Rhodamin B ile boyandı. Fiber postların simantasyon işleminden sonra, örnekler kesitlere ayrıldı ve elde edilen kesitlere push-out testi uygulandı ve simanların dentin tübül penetrasyon değerlendirmesi için de konfokal lazer tarama mikroskobu kullanıldı. Bulgular: Push out testi değerlendirildiğinde gruplar içinde sadece KD+/ Maxcem Elite grubu servikal bölgede en düşük bağlanma değerlerini gösterdi p 0.05 . Sonuç: KD- grup, KD+ gruba göre daha iyi dentin tübül penetrasyon değerleri gösterdi.
