Abstract
Objectives: This invitro research investigated shear bond strength (SBS) of resin cement to zirconia ceramics after different artificial aging.
Methods: 60 zirconia discs were CAD-CAM fabricated. Composite discs were bonded to conditioned zirconia discs using adhesive resin cement. Specimens were divided into 6 test groups according to artificial aging condition: 30000 cycles of cyclic loading test group (1), 5 months of water storage +30000 cycles of cyclic loading test group (2), 5 months of Water storage + 5000 cycle of thermocycling test group (3), 5000 cycle of Thermocycling test group (4), 5 months of Water storage test group (5) and 5 months of water storage +5000 cycles of thermocycling + 30000 cycles of cyclic loading test group (6). A universal testing machine was used for SBS test to all specimens. One-way ANOVA and post-hoc Tukey tests were used for statistical analysis.
Results: Group 1 recorded the highest shear bond strength showed means ± SD record (9.35 ± 2.25) followed by group 4 which means ± SD record (8.53 ±4.92) followed by group 2 which means ± SD record (6.92 ± 1.04) followed by group 3 and group 5 respectively which means ± SD records (5.97 ± 2.57) and (4.72 ± 1.30) while the lowest shear bond strength was for group 6 with means ± SD record (3.75±1.19).
Conclusions: The influence of water storage in combination with thermocycling and cyclic loading on SBS is higher than the effect of thermocycling alone and cyclic loading alone.
