- Abstract
PURPOSE: To investigate the adequate luting cements for zirconia ceramics to dentin. METHODS: Blocks of sintered zirconia ceramics were randomly divided into 4 groups with 8 slices in each. Alter saliva immersion, airborne-particle abraded ceramic specimens were cleaned with phosphoric acid gel (containing 35% phosphoric acid) and then bonded to dentin with these four kinds of luting cements. After preserved in 37°C distilled water for 24 hours, the shear bonding strength of these specimens was tested and the data was analyzed with SPSS 12.0 software package. RESULTS: The Multilink Automix could attain the highest shear bonding strength and the 3M RelyX™ Unicem Aplieap™ could attain higher shear bonding strength, which were both significantly higher than in the Tokuso Ionomer and Shofu Polycarboxylate Cement groups (P<0.05). CONCLUSION: Total etching resin luting cement is an ideal option to the bonding of zirconia ceramics and can provide a strong bonding.
