Effect of Artificial Saliva and pH on Shear Bond Strength of Resin Cements to Zirconia-Based Ceramic

doi:10.1922/EJPRD_1065Sadighpour04

Abstract - The aim of the present study was to evaluate the effect of media with different pH on shear and strength of resin cements to zirconia-based ceramics. Sixty rectangularly shaped specimens made of a zirconia based ceramic (Cercon, Dentsply) were prepared, air-blasted with 110 µm aluminum oxide particles (Al2O3) and randomly assigned into three groups (n=30). A universal resin composite (Filtek Z250, 3M/ESPE) was bonded to each specimen using one of the following three cements: Calibra (Dentsply), Panavia F2 (kurary) and Unicem (3M/ESPE). Specimens were thermal cycled and stored in one of the following three media for two weeks: water at pH=7, saliva at pH=7 and saliva at pH= 3.5. The mean shear bond strength of each group was analyzed using the Kruskal-Wallis test (a=0.05). The modes of failure were recorded using a streomicroscope. All specimens in the Calibra groups showed premature debonding. No significant difference was found between the two other cements or different media. The failure modes in the two latter cements were predominantly adhesive. Despite the adverse effect of acidic media on the properties of restorative materials, the media did not significantly influence the bond strength of MDP-containing resin cement and a self-adhesive cement to a zirconia- based ceramic.
