Purpose: This study compared shear bond strengths of five self-adhesive cements with phosphate monomer to zirconium oxide ceramic with and without airborn particle abrasion.

Materials and methods: One hundred zirconia samples were air-abraded (50 um Al2O3). One hundred composite resin cylinders were fabricated. Composite cylinders were bonded to the zirconia samples with either Permacem 2.0 (P), Clearfil(TM) SA Luting (C), Multilink Speed (M), RelyX(TM) U200 Automix (R), G-Cem LinkAce(TM) (G). All bonded specimens were stored in distilled water (37 degreeC) for 24 h and half of them were additionally aged by thermocycling (5 degreeC, 55 degreeC, 5,000 times). The bonded specimens were loaded in shear force until fracture (1 mm/min) by using Universal Testing Machine (Model 4201, Instron Co, Canton, MA, USA). The failure sites were inspected under field-emission scanning electron microscopy. The data was analyzed with ANOVA, Tukey HSD post-hoc test and paired samples t-test (a=.05).

Results: Before and after thermocycling, Multilink Speed (M) revealed higher shear-bond strength than the other cements. G-Cem LinkAce(TM) (G) showed significantly lower bond strengths after thermocycling than before treatment (P<.05), but the other groups were not significantly different (P>.05).

Conclusion: Most self-adhesive cements with phosphate monomer showed high shear bond strength with zirconia ceramic and werent influenced by thermocycling, so they seem to valuable to zirconia ceramic bonding.
