The effect of surface treatments of tooth on the shear bond strength of direct composite veneers: An scanning electron microscope study.

Background: The bond strength between tooth structure and restorative materials is critical for the long-term success of dental restorations. This study sought to determine how the shear bond strength (SBS) and type of bond breakdown were affected by the inclusion of sandblasting (SB) as a conditioning step before acid etching (AE).

Materials And Methods: A total of 40 extracted human molars were split into two groups at random: intervention (SB followed by AE) and control (AE only).
