The purpose of this study was to evaluate shear bond strength (SBS) of dual cure self adhesive resin cement to zirconia treated by plasma polymerization using two types of monomer (acrylic acid or allylamine) and different outputs (30, 50, 70 and 90 W).
After preparing 43x25x8mm zirconia blocks (Ice Zirkon, Zirkonzahn), they were treated with plasma polymerization and divided into 10 groups according to outputs of plasma polymerization treatment and monomer types (acrylic acid, allylamine) including control group and silica blasting group. On the zirconia blocks treated with plasma polymerization, self adhesive resin cement (Rely X Unicem, 3M ESPE) was used for adhesion using a silicon mold and light-cured for 40 seconds (Curing Light XL 3000, 3M ESPE). The samples were kept in drilled water for 24 hours, FE-SEM evaluation was performed after measuring SBS using universal testing machine (1 mm/min). The results was analyzed statistically using one-way ANOVA, Tukey HSD and independent samples t-test in SPSS Ver.17 with significance value of 0.05.
The silica blasting treatment groups showed the highest shear bond strength and significantly higher strength than any other experimental groups except group 1 and 3. Regardless of monomer types and output, all plasma polymerization surface treatment groups showed lower shear bond strength than control groups (p < 0.05). Plasma polymerization surface treatment showed no significant differences on the types of monomers and out-puts.
In conclusion, plasma polymerization using acrylic acid or allylamine monomer on zirconia do not increase the adhesive property of self adhesive resin cement irrespective of the outputs.
