Abstract

Amaç: Bu çalışmanın amacı, CAD/CAM yüzeylerinde gerçekleştirilen yapıştırma prosedürünün farklı aşamalarında gerçekleşen tükürük kontaminasyonun, su ya da etanol ile temizlenmesinin bağlanma dayanıma etkisini incelemektir.
Gereç ve Yöntem: Cerasmart (GC) ve Shofu Block (Shofu) CAD/CAM materyallerden (772 mm) hazırlanan örnekler, otopolimerizan akrilik ile sabitlendi. Örneklerin yüzeyleri Al2O3 kum ile kumlandı, arkasından çalışma protokollerine göre şu şekilde gruplara ayrıldı: Grup-1(kontrol): Firma önerisi yapıştırma protokolü (Primer/Siman/Kompozit), Grup-2: Tükürük-kontaminasyonu / Su ile temizleme/Primer/Siman/Kompozit, Grup-3: Tükürük-kontaminasyonu / %70 etanol ile temizleme /Primer/Siman/Kompozit, Grup-4: Primer-uygulaması/ Tükürük-kontaminasyonu / Su ile temizleme / Tekrar primer-uygulaması/Siman/Kompozit, Grup-5: Primer-uygulaması / Tükürük-kontaminasyonu / %70 etanol ile temizleme / Tekrar-primer uygulaması /Siman/Kompozit. Her grup için CAD/CAM materyallere primer olarak Z-Prime Plus 10 sn uygulandı. Ardından hazırlanan kompozit rezinler (Clearfil Majesty ES-2, Kuraray), dual-cured rezin siman (Duo-Link Universal Light Curing Resin Cement, BİSCO) aracılığıyla yapıştırıldı. Örnekler 24 saat 37 oC suda bekletildi ve bağlanma dayanım testine tabi tutuldu. Veriler tek yönlü varyans analizi (ANOVA) ve Tukey HSD testi kullanılarak analiz edildi (p<0.05).
Bulgular: En yüksek bağlanma dayanımı değeri Cerasmart Grup-1’de (19.865.27.), en düşük bağlanma dayanımı değeri Shofu Block HC Grup-5’te (13.024.83) bulundu (p=0.67). Tükürük kontaminasyonun primer uygulamasından önce veya sonra gerçekleşmesi bağlanma dayanım değerlerini etkilemedi. Her iki materyal içinde dekontaminasyon işleminin su ya da %70 etanol ile gerçekleştirilmesi arasında istatistiksel olarak anlamlı farklılık bulunmadı.
Sonuç: Kontaminasyonun primer uygulamasından önce veya sonra meydana gelmesinin bağlanma dayanımına etkisi bulunmamaktadır. Uygulanan her iki dekontaminasyon yöntemi de klinik olarak yeterli bağlanma dayanımı sağlamaktadır. Primer kullanımı, gelişmiş bağlanma dayanımı değerleri üzerinde etkilidir.

The Effect of Different Surface Decontamination Procedures on the Bond Strength Values of CAD/CAM Restoratives
ABSTRACT
Aim: The aim of this study is to examine the effect of saliva contamination, which occurs at different stages of the bonding procedure on CAD/CAM surfaces, on the bond strength of decontamination with water or ethanol.
Materials and Methods: Samples prepared from GC Cerasmart and Shofu Block CAD/CAM materials (772 mm) were fixed with autopolymerizing acrylic. The surfaces of the samples were sandblasted with Al2O3, then were divided into groups according to study protocols.
Group-1 (control):Company recommendation bonding protocol (Primer/Cement/Composite), Group-2:Saliva-contamination/Cleaning with water/primer/cement/composite, Group-3:Saliva-contamination/Cleaning with 70% ethanol/primer/cement/composite Group-4:Primer-application/Saliva-contamination/Cleaning with water/Re-primer-application/cement/composite, Group-5:Primer-application/Saliva-contamination/Cleaning with 70% ethanol/Re-primer-application/cement/composite. For each groups, Z-Prime Plus was applied to the CAD/CAM for 10-seconds as a primer. After, the composite resins (Clearfil Majesty ES-2, Kuraray) were bonded via dual-cured resin cement (Duo-Link resin cement, Bisco). The samples were kept in 37 oC water for 24 hours and subjected to the bond strength test. Data were analyzed with one way Analysis of Variance (ANOVA) and Tukey HSD tests (p0.05).
Results: The highest bond strength value was found in Cerasmart Group-1 (19.865.27.) and the lowest value was found in Shofu Block Group-5 (13.024.83)(p=0.67). The occurrence of saliva contamination before or after primer didn’t affect the bond strength values. There was no statistically significant difference between decontamination with water or 70% ethanol for both materials.
Conclusions: Contamination occurred before or after the primer has no effect on bond strength. Both decontamination methods provide clinically sufficient bond strength. The use of primer is effective on improved bond strength values.
