Objective: To investigate the effect of water storage on repair bond strength (RBS) of resin composite to five restorative materials using either a silane and a bonding agent or a universal bond. Materials and Methods: Five materials which are amalgam, direct composite, indirect composite, hybrid ceramic, and feldspathic ceramic were used in this study. Twenty- eight cube-shaped specimens from each material were fabricated, all specimens were sandblasted (Al2O3; 50 µm) and then classified into two equal groups (n=14) according to the surface treatment method (total-etch bond and silane coupling agent or universal bond). Each group was further divided into 2 …
