Abstract
Abstract
This study compared the effects of 3 different cavity disinfection protocols (CDP) on the shear bond strength (SBS) of resin- modified glass ionomer cement (RM- GIC) to mineral trioxide aggregate (MTA). One hundred eighty standard holes were prepared and filled with MTA. They then divided into 3 main groups based on the chosen time intervals (15 min, 24 h, and 72 h). Main groups were divided into 3 subgroups based on the CDP [chlorhexidine gluconate (CHX), ozone, laser, and control]. RM- GIC was applied on MTA after CDP for all groups. A universal testing device was then used for test and the data was statistically analysed. CHX showed significantly lower SBS values except ozone and laser than the control (p< 0.05). There were no statisti-cally significant differences among the time intervals. As a result, CHX decreased the bond strength between the MTA and RM- GIC while ozone and laser had no negative effect.
