ABSTRACT

This study evaluated porcelain repair by use of various surface treatments [Hydrofluoirc acid etching, diamond roughening,sandblasting and no surface treatment [control]] for two types of porcelain [conventional feldspathic[CeramcoII]] and low fusing porcelain [Duceram]] bonded with two types of composite resin [light cured hybrid composite resin [Prisma composite] and heat cured inlay composite resin [Charisma composite]]. Shear bond strengths were determined on a universal testing machine. The result revealed that, shear bond strength of conventional porcelain is higher than low fusing porcelain, inlay composite bond beter than light cured composite and the most effective surface treatment was hydrpfluoric acid etching
