Özet
Giriş: Endodontik kanal dolgu patlarının kök kanal dentinine adezyonu, kanal duvarı ile dolgu materyali arasındaki ilişkiyi göstermek açısından önemli ipuçları verir. Amaç: Bu çalışmanın amacı yeni bir kök kanal dolgu patı olan RC Sealer'm dentine adezyonunu RoekoSeal, AH26 (gümüşsüz) ve Ketac-Endo'yla karşılaştırmaktı. Materyal ve Metot: Çalışmada 60 adet insan 3. molar dişi kullanıldı. Tensile dayanım testi için dişlerin kronları orta üçlü bölgesinden yatay olarak kesilerek pulpa odası tavanı dentin yüzeyleri kullanıldı. Kanal dolgu patları özel olarak dizayn edilmiş alüminyum parçalar yardımıyla dik açıyla olacak şekilde bu örnekler üzerine yerleştirildi. Hazırlanan örnekler kanal dolgu patı sertleşmesi için 7 gün süreyle 37C sıcaklıkta ve nemli atmosferde inküba-törde bekletildi. Daha sonra düzenek universal testing machine (Testometric Micro 500, İngiltere) için hazırlanan bir alüminyum çerçeve içine yerleştirildi ve örneklere 0.5 mm.dak.-l hızla tensile güç uygulandı. Veriler MPa olarak kaydedildi ve sonuçlar istatisiksel olarak değerlendirildi. Bulgular: Çalışma sonuçları dentine adezyon yönünden RC Sealer'la AH26 ve RoekoSeal'le Ketac-Endo arasında istatistiksel olarak anlamlı bir fark olmadığını (p0.05), ancak RC Sealer ve AH26'nın adezyonunun RoekoSeal ve Ketac-Endo'dan daha yüksek olduğunu gösterdi (p0.05). Sonuç: Çalışmada test edilen materyallerin tümü dentine adezyon özelliği göstermiştir. Ancak RC Sealer ve AH26 kanal dolgu patları Ketac-Endo ve RoekoSeal'le karşılaştırıldığında daha iyi adezyon potansiyeline sahip bulunmuştur.
Introduction: Adhesion of endodontic sealers to den¬tin offers clues into their interaction with the wall of the root canal and the filling material. Objective: The purpose of this study was to evaluate dentin adhesion of a recently developed sealer RC Sealer comparing with commercial root canal sealers, RoekoSeal, silver-free AH26 and Ketac-Endo. Material and Methods: Sixty extracted human third molar teeth were used. The crowns were horizontally cut from the middle third and roof dentin surfaces of pulp chambers were used for tensile strength test. Root canal sealers were placed onto the specimens' surface at an angle of 90 degree by the help of a specially designed aluminum apparatus and allowed to set for 7 days in an incubator providing a moist atmosphere at a temperature of 37oC. This set-up was then placed into an aluminum frame which was designed for universal testing machine (Testometric Micro 500, England) and a tensile force was applied at a cross head speed of 0.5 mm.min-1. The data were recorded as MPa and the results were evalu¬ated statistically. Results: The results of the study revealed that there were not statistically significant difference among RC Sealer and AH26 (p>0.05). RoekoSeal's adhesion was similar that of Ketac-Endo (p>0.05). However, adhesion of both RC Sealer and AH26 were better than RoekoSeal and Ketac-Endo (p<0.05). Conclusion: It was concluded that all of the tested materials have adhesive properties however RC Sealer and AH26 have better adhesion potential when compared to Ketac-Endo and RoekoSeal.
