Hybrid ceramic is a polymer-infiltrated ceramic network (PICN) that has been widely used in recent years due to its esthetic properties and biocompatibility. Moreover, the possibility of less invasive restorations. Achieving higher bond strength in ceramic restoration is required in mechanical and chemical approaches. In case repaired hybrid ceramic is needed, resin composite is a material of choice because it can be directly repaired in the oral cavity and is tooth-liked color. Surface treatment is recommended to provide better bond strength. This study compares the effect of different surface treatments on the shear bond strength of repaired hybrid ceramic with resin composite. Forty specimens (6x11x2 mm) were prepared from VITA Enamic. All specimens were divided randomly into 4 surface treatment subgroups (n=10). Group 1: Control group, Group 2(HF): Etching with 5% hydrofluoric acid for 60 seconds, Group3(SB): Sandblasting at specimen surface for 15 seconds, Group 4(SC): Grinding with sandpaper grit 120 for 4 seconds. Then, all groups were applied with a silane coupling agent followed by placing a resin composite on the treated specimen surface using a metal split mold and then storing all specimens at 37 oC for 24 hours. The specimens were tested for shear bond strength using a Universal testing machine and analyzing the failure mode with a stereomicroscope. The mean shear bond strength data were analyzed using One-way ANOVA followed by Tukey’s test at a confident level of 95%. The result revealed that the HF group promoted the highest bond values while the control group showed the least values of shear bond strength. There were no significant differences between HF and SB groups or SB and SC groups.
