Özet
The purpose of this study is to investigate the effects of various surface treatments and universal adhesives on the changes in the glass fiber posts (GFPs) surface and the bond strength between resin cement-post and core composite-post. A total of 20 groups (n = 16) were formed, 10 groups for resin cement and 10 groups for core composite. Various surface treatments, including acid etching and silane application, and two different universal adhesives (Single bond Universal, All Bond Universal) were applied. After various surface treatments and adhesives were applied to the GFPs surface, the surface properties were examined by energy-dispersive X-ray spectroscopy (EDX) analysis. Standard silicone molds were prepared to bond the resin cement and core composite with the GFPs. The serial 1 mm thickness bar was taken from each sample. Microtensile bond strength (& mu;TBS) test was performed and failure modes were evaluated by scanning electron microscopy (SEM). Statistical analysis was performed using a two-way analysis of variance and Tukey's post hoc tests (p = 0.05). The bond strength values of the groups that applied 37% orthophosphoric acid (OPA), silane, and universal adhesive to the GFPs surface before the resin cement and core composite were statistically significantly higher than the control group (p < 0.05). In the resin cement study, the group using silane and Single Bond Universal showed higher bond strength than the other groups (p < 0.05). Acid etching and silane application before the use of universal adhesives increased the & mu;TBS in both resin cement and core composite groups.
