520 _aEnhance the bonding of cement to ceramic surface with a variety of ceramic surface modifications have been established. Air-abrasion using alumina particles, hydrofluoric acid has been shown to provide micromechanical interlocking at the ceramic-resin interface` The aim of the present study was to evaluate the effect of two surface treatments; acid etching and sandblasting; on the shear bond strength of cemented newly introduced zirconia-reinforced lithium silicate ceramics following thermocycling. Methods 24 discs of Zirconia- reinforced glass ceramics (celtra duo) were tested using 10% hydrofluoric acid for 20 seconds (control group) and 50 om aluminum oxide for 60 seconds at 10mm distance from the nozzle tip of sandblasting machine. Subsequent the surface treatments both groups were salinized and cemented to composites background discs using self-adhesive duel cure resin cement (BisCem). All sample were subjected to 2500 thermal cycle shear bond strength and failure mode was evaluated
