Abstract

Aim: To compare the push-out bond strength of BioAggregate cement and X-tra base composite resin and the effect of EDTA and chlorhexidine irrigation solutions on push-out bond strength of these materials. Material and Method: Twenty-four maxillary central incisor teeth were included to the study. Teeth were prepared up to apical diameter #40 using ProTaper Next rotary system. Than, a parallel post drill with 1.25 mm diameter was used to create a 10 mm long space. 12 of the samples were irrigated with 2 ml 17% EDTA for 2 minutes, 2 ml 5.25% NaOCl and 5 ml distilled water respectively. Other 12 of the samples were irrigated with 2 ml 17% EDTA for 2 minutes, 2 ml 5.25% NaOCl, 2 ml distilled water, 2 ml 2% CHX and 5 ml distilled water respectively The roots were cut into 1-mm-thick parallel transverse sections in a coronal-to-apical direction 5 slice per tooth . Half of the slices were restorated with BioAggregate and the other slices were restorated with X-tra base composite resin. A push-out test was performed, and the data were analyzed statistically using Student-t test P < 0.05 . Results: A significant effect of irrigation solution on push-out bond strength of BA and XTB was not observed P > 0.05 . Regardless of the type of irrigation solutions used, XTB had significantly higher bond strength than BA P < 0.05 . Conclusion: Within the limitation of the present study XTB bulk-fill composite resin had the higher push-out bond strength than BA cement.

İrrigasyon Solüsyonlarının Koronal Bariyer Materyallerinin Bağlantı Dayanımına Etkisi

Abstract

Amaç: BioAggregate simanı ve X-tra base kompozit rezinin push-out bağlantı dayanımlarını ve push-out bağlantı dayanımlarına EDTA ve klorheksidin irrigasyon solüsyonlarının etkisinin karşılaştırılmasıdır.Gereç ve Yöntem: Çalışmaya 24 adet maksiller orta keser diş dahil edildi. Dişlerin apikali #40 olacak şekilde ProTaper Next döner alet sistemi ile şekillendirildi. Daha sonra çapı 1.25 mm olan paralel bir post dirili yardımıyla kök kanalı içerisinde 10 mm uzunluğunda boşluk hazırlandı. Örneklerin 12 tanesinin kök kanallarının son yıkaması için sırası ile 2 ml %17 EDTA 2 dakika boyunca, 2 ml %5,25’lik NaOCl ve son olarak 5 ml distile su kullanıldı. Diğer 12 tanesinin son yıkaması için 2 ml %17 EDTA 2 dakika boyunca, 2 ml %5,25’lik NaOCl, 2 ml distile su, 2 ml %2 CHX ve 5 ml distile su kullanıldı. Kök kanalları hazırlanmış her bir dişten korono-apikal yönde kesitlerin kalınlığı 1 mm olacak şekilde su soğutması altında 5 adet horizontal kesit alındı. Kesitlerin yarısına BioAggregate diğer yarısına ise X-tra base kompozit rezin uygulandı. Daha sonra örneklerin push-out bağlantı dayanımları ölçüldü. Elde edilen veriler Student-t testi ile istatistiksel olarak değerlendirildi P < 0,05 .Bulgular: İrrigasyon solüsyonun materyallerin bağlantı dayanımına istatistiksel olarak etki etmeği bulundu P > 0,05 . XTB grubunun irrigasyon solüsyon türüne bakılmaksızın BA grubundan istatistiksel olarak dentine daha yüksek bağlantı dayanımı gösterdiği tespit edildi P < 0,05 .Sonuç: Çalışmamızın sınırları dahilinde XTB bulk-fill kompozit rezininin pushout bağlantı dayanımının kalsiyum silikat esaslı BA simanından daha yüksek olduğu bulunmuştur
