摘要
To evaluate the effect of silica coating with Sol-Gel processing on the bonding strength between dental high-strength ceramic and composite resin. Method: 80 zirconia ceramic discs were randomly divided into four groups (n=20 in each group), and received different surface treatments, then the shear bonding strength of the ceramics and composite resin were calculated. Results: The three groups with silica coating had a higher bonding strength than the un-coated group with a significant difference (P<0.05); group C had the highest bonding strength (P<0.05). There were no significant differences between group B and group D (P>0.05). Conclusion: Silica coating followed by silane coupling agent treatment can significantly increase bonding strength between dental ceramic and composite resin; 30% silica sol may be more effective.
