The surface of zirconia was treated with hot-acid etching of different durations to improve its shear bond strength to resin. Zirconia discs were subjected to untreated, sand-blasting, and hot-etching treatments for 10, 30 and 60 min. The discs were bonded to the surface of bovine enamel specimens using RelyX Ultimate resin cement. The bonded specimens were divided into immediate and thermocyling aging groups according to whether they underwent thermal cycling. A universal mechanical testing machine was used to measure the shear bond strength of the specimens. One-way analysis of variance was used to determine the effect of hot-etching time on the shear bond strength. In the immediate and thermocyling aging groups, 60 min of hot-etching provided significantly higher shear bond strength than the other conditions (p<0.05).
