Abstract The aim of this study was to evaluate the shear bond strength (SBS) of three different cements to zirconia and lithium disilicate ceramic surface after thermal cycling. Thirty zirconia (Z) and thirty lithium disilicate (L) disk specimens were prepared in 8 mm in diameter and 3.4 mm in thickness from zirconia and lithium disilicate ceramic blocks. Each group was divided into three subgroups (n:10). The specimens from all groups were bonded with three different cements using transparent polyethylene tubes: ZnPhosphate cement (ZPC); self-adhesive resin cement (SARC); adhesive resin cement (ARS). The specimens were then subjected to thermal aging procedure for 1 week under 37 °C water bath. Shear bond strength (SBS) was determined using a universal testing machine at a crosshead speed of 1 mm/min. The specimens were also examined both with a scanning electron microscope (SEM) and a stereomicroscope. Statistical analysis was performed with one-way ANOVA. Pair-wise statistical comparison was made with Tukey test. The overall significance level was set at α = 0.05. For the tested groups, the SBS values ranged from 0.29 ± 0.03 to 12.10 ± 0.25 MPa. L-SARC group yielded the highest SBS value (p
