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.
