Abstract

This study aimed to evaluate the effect of various silane-containing solutions on bonding between resin cement and glass ceramic after 24 hours and after six months of water storage. Glass-ceramic plaques (IPS e.max CAD) were sandblasted with aluminum oxide, etched with 10% hydrofluoric acid (HF), and divided into five ‘‘silane treatment’’ groups: RelyX Ceramic Primer (RCP), RelyX Ceramic Primer and Single Bond Plus (RCP+SB), Scotchbond Universal (SBU), Clearfil Ceramic Primer (CP), and no solution (HF-only control). Each group was divided into two ‘‘storage time’’ subgroups: 24 hours or six months in 378C water. Eighteen resin cement cylinders (RelyX Ultimate) were bonded to each treatment group substrate (n=18) and then subjected to microshear testing. Failure mode was analyzed using scanning electron microscopy. Debond data were analyzed using a two-way analysis of variance and the Tukey post hoc test (a=0.05) as well as Weibull distributions. The factors ‘‘silane treatment,’’ ‘‘storage time,’’ (p,0.0001), and their interaction were statistically significant (p,0.0010). Group means (MPa6SD), RCP (24 hours: 27.263.1; six months: 18.064.9), and HF-only control (24 hours: 21.163.4; six months: 15.765.8) showed a reduced bond strength after six months of water storage, while RCP + SB (24 hours: 23.464.4; six months: 22.265.4), SBU (24 hours: 18.863.0; six months: 17.263.6), and CP (24 hours: 21.764.3; six months: 17.464.8) remained constant. Weibull analysis revealed that more reliable bond strengths were obtained after six months for SBU and RCP + SB. Evaluation by scanning electron microscopy revealed that all groups demonstrated hydrolytic degradation at six months of storage, but RCP + SB and SBU indicated less. Use of a separate application of silane and adhesive system improved short and long-term ceramic/resin cement bond strength.
