Abstract
|
|
|
Enhancement of bond strength between new and old composite usually requires increasing the surface roughness to
promote mechanical interlocking. This study evaluated the effect of different surface treatments on repair bond strength of
resin composite after aging condition. Air abrasion with Al2O3, chairside silicacoating, and silanization provided higher resin-resin bond strength values compared to control group and HF group. Air abrasion is necessary to repair a resin restoration and additional application of silane seems to have good effects on bond strength.
