Abstract

Purpose: Aim of this study was to evaluate the effect different application methods of total-etch adhesives containing different solvents on microtensile bond strength to dentin.Material and Methods: Teeth were randomly divided into three groups according to adhesive systems and solvent type; each group was divided into two subgroups according to application method (n=10). Total-etch adhesives were applied with or without rubbing action and light cured. After bonding procedures resin composites were bonded and light cured. Specimens were subjected to thermocycle then microtensile force and obtained data were analyzed statistically.Results: Rubbing action significantly improved bond strength to dentin (p<0,001). Tertiary butanol containing adhesive showed highest bond strength values with or without rubbing action (p<0,05).Conclusion: Regardless of the adhesive system, rubbing of adhesive resins to dentin surface could increase bond strengths. Due to their high performances, adhesives containing tertiary butanol as solvent could be suggested.

FARKLI ÇÖZÜCÜ İÇEREN TOTAL-ETCH ADEZİFLERİN FARKLI UYGULAMA YÖNTEMLERİNİN BAĞLANMA DAYANIMINA ETKİSİ

Abstract

Amaç: Farklı çözücü (aseton, etanol ve tersiyer butanol) içeren total-etch ve self-etch adeziflerin iki farklı uygulama yönteminin derin dentinde mikrogerilim bağlanma dayanımı üzerine etkisinin değerlendirilmesi amaçlanmıştır. Gereç ve Yöntem: Dişler çözücü tipi ve adezif sisteme göre 20’şerli rastgele 3 ana gruba; her ana grup da uygulama yöntemine göre kendi içinde 2 alt gruba bölündü (n=10). Total-etch adezifler dentin yüzeyine fırçayla ovalanarak veya ovalanmadan uygulanıp polimerize edildi. Örneklere kompozit adezifler bağlanıp, termal siklusa uygulandıktan sonra mikrogerilim kuvvetine maruz bırakıldı. Veriler istatistiksel olarak değerlendirildi. Bulgular: Tüm adezifler için fırçayla ovalama uygulamasının bağlanma dayanıklılığını istatistiksel olarak da anlamlı miktarda arttırdığı görüldü (p < 0.001). Tersiyer butanol içeren total etch adezif ovalanarak ya da ovalanmadan uygulandığında en yüksek bağlanma dayanıklılığı değerlerine sahip oldu. Sonuç: Adezif sistemden bağımsız olarak adeziflerin dentin yüzeyine ovalanarak uygulanması sonucu bağlanma dayanıklılığı değerlerini arttırabilir. Çözücü olarak tersiyer butanol içeren adezifler yüksek performansları nedeniyle önerilebilir.
