초록

This study evaluated the effect of time before addition and surface treatment on the shear bond strength between new and old(direct and indirect) composites. One hundred specimens of Charisma(Heraeus Kulzer, Germany) and thirty-five of Artglass(Heraeus Kulzer, Germany) were prepared in cavities($10mm{\times}5mm$) in acrylic resin molds. Charisma specimens were stored for 5min., 1hr., 24hrs., and 1 week in $37^{\circ}C$ distilled water and Artglass specimens were stored for 1 week in $37^{\circ}C$ distilled water.(omitted)
