Abstract

Aim: This study compares the push-out bond strengths of 3 different fiber post systems bonded with resin cement to root canal dentin.
Material and Methods: The study used 15 extracted single-rooted mandibular canine teeth. After the endodontic treatment of the teeth, they were randomly divided into three groups to apply different post-systems(n=5). Reforpost glass-fiber, Polydentia glass-fiber, and AAA Transparent fiber post systems were used in this study. The posts have adhered to the root canal with Panavia F2.0. A total of 6 slices of 1 mm thickness in the transversal direction were obtained, two from each of the coronal, middle, and apical sections of the prepared samples. The push-out test was performed from apical to coronal at a 0.5 mm/min speed. ANOVA and Tukey HSD tests were used for statistical analysis(p<0.05).
Results: The highest push-out binding values were observed in the Polydentia(5.04±0.54); the lowest was seen in the Reforpost(1.5±1.03). There was no statistical difference between the push-out binding values of the samples' apical, middle, and coronal regions for the Reforpost and Transparent groups. In the Polydentia group, the push-out binding values of the coronal region samples were significantly higher than those in the middle region. When the post groups were compared, the difference between the push-out binding values of all groups was statistically significant.
Conclusion: The surface properties of the posts can affect the push-out bonding values. Polydentia showed the highest push-out binding values. In addition, the push-out attachment values of the posts may vary in different root canal regions.

Rezin simanla yapıştırılan farklı fiber post sistemlerin push-out bağlanma dayanımlarının karşılaştırılması

Abstract

Amaç: Bu çalışmanın amacı, rezin simanla kök kanal dentinine bağlanan üç farklı fiber post sisteminin push-out bağlanma dayanımları karşılaştırmaktır.
Gereç ve Yöntemler: Çalışmada 15 adet çekilmiş tek köklü kanin diş kullanıldı. Dişlere endodontik tedavi yapıldıktan sonra farklı post sistemi kullanılmak üzere rastgele 3 gruba ayrıldı (n=5). Çalışmada, Reforpost cam fiber post, Polydentia cam fiber post ve AAA Transparent fiber post sistemleri kullanıldı. Postlar kanal içine Panavia F2.0 ile üretici firmanın talimatları doğrultusunda yapıştırıldı. Hazırlanan örnekler %100 nemde 24 saat 37 °C'de 1 gün bekletildikten sonra her bir diş kökünün postu içeren kısmının koronal, orta ve apikal bölümlerinin her birinden 2’şer adet olmak üzere, 1 mm kalınlıkta transversal yönde toplam 6 kesit elde edildi. Push-out testi, 0,5 mm/dk hızla apikalden koronale doğru yapıldı. Verilerin istatistiksel analizi için ANOVA ve Tukey HSD testleri uygulandı (p<0.05).
Bulgular: En yüksek push-out bağlanma değerleri Polydentia grubunda (5.04±0.54) görülürken; en düşük değerler reforpost grubununda (1.5±1.03) görüldü. Reforpost ve AAA Tranparent gruplarının apikal orta ve koronal bölge örneklerinin push-out bağlanma değerleri arasında istatistiksel olarak farklılık görülmedi (p>0.05). Polydentia grubunda ise; koronal bölge örneklerinin push-out bağlanma değerleri orta bölgedeki örneklerden anlamlı olarak daha yüksek bulundu (p=0.006). Post grupları birbirleriyle karşılaştırıldığında; tüm grupların push-out bağlanma değerleri arasındaki fark istatistiksel olarak anlamlı bulundu (p<0.05).
Sonuç: Postların yüzey özellikleri push-out bağlanma değerlerini etkilemektedir. Polydentia en yüksek push-out bağlanma değerlerini göstermiştir. Ayrıca postların push-out bağlanma değerleri kökün farklı bölgelerinde değişkenlik gösterebilmektedir.
