Abstract

Purpose: To evaluate the effect of 4 different chemical surface treatments on the bond strength of a composite resin to glass and quartz fiber post surfaces. Material and Methods: Thirty two specimens from each posts systems, total 64 post slices (3 mm height x 2mm diameter) were prepared. Specimens were mounted into acrylic blocks. The specimens were divided into 4 subgroups (n=8) to apply surface treatments. In control group 60 s silane coupling agent, in other groups methylene chloride for 5 s, methylene chloride for 30 s and 24% hydrogene peroxide for 20 min were applied. A composite resin (Tetric EvoCeram) was placed to specimens surfaces. Shear bond strength (MPa) were measured using a universal testing machine. Data were statistically analyzed by 2-way analysis of variance (ANOVA) and Tukey HSD test (a=0.05). The effect of the chemical surface treatments on glass and quartz fiber post surfaces were examined with scanning electron microscope (SEM). Results: Surface treatments and type of fiber post affected the bond strength of composite resin (P<0.001). The highest bond strength values were obtained on glass fiber post surfaces with the application of hydrogen peroxide (P<0.001). No significant differences were found between the application of methylene chloride and silane coupling agent on quartz fiber post surfaces. Conclusions: Application of hydrogene peroxide and methylene chloride for 30 s affected bond strength of fiber post by dissolving epoxy resin matrix. The application of methylene , chloride for 5 s was not found to be effective for increasing bond strength.

Özet

Amaç: Cam ve kuartz fiber post yüzeylerine uygulanan 4 farklı kimyasal yüzey işleminin bir kompozit rezinin bağlanma dayanıklılığına etkisini değerlendirmektir. Gereç ve Yöntem: Her bir post sisteminden 32 adet toplam 64 adet post dilimi (3 mm yükseklik x 2mm çap) hazırlandı. Örnekler akrilik bloklar içerisine yerleştirildi. Yüzey işlemlerinin uygulanabilmesi için örnekler 4 alt gruba (n:8) ayrıldı. Kontrol gruplarında 60 sn silan bağlayıcı ajan, diğer gruplarda 5 sn metilen klorid, 30 sn metilen klorid ve 20 dak %24 'lük hidrojen peroksit uygulandı. Örnek yüzeylerine bir kompozit rezîn (Tetric EvoCeram) yerleştirildi. Kesme bağlanma dayanıklılığı (MPa) bir universal test cihazı ile ölçüldü. Veriler iki-yönlü varyans analizi ve Tukey HSD testi ile istatistiksel olarak analiz edildi (a=0.05). Kimyasal yüzey işlemlerinin post yüzeylerine etkisi bir tarayıcı elektron mikroskobu (SEM) ile incelendi. Bulgular: Yüzey işlemleri ve fiber post tipi kompozit rezinin bağlanma dayanıklılığını etkiledi (P 0.05). Sonuç: Hidrojen peroksit ve 30 sn metilen klorid uygulaması fiber postların epoksi rezin matriksini çözerek bağlanma dayanıklılığını etkiledi. Metilen Kloridin 5 sn boyunca uygulanması bağlanma dayanıklılığını arttırmada etkili bir yöntem değildir.
