Effects of an etching solution on the adhesive properties and surface microhardness of zirconia dental ceramics.

Statement Of Problem: Conventional approaches to adhesive bonding are not applicable to zirconia restorations. Recently, an etching solution, Zeta Etching Solution (ZES), has been introduced for etching the surface of zirconia. The effects of this etching solution on the bond strength and mechanical properties of zirconia are unknown.
