Abstract：AIM:To study the effects of dentin moisture condition on the closure property of 4 root canal sealants.METHODS:1 12 freshly extracted permanent teeth with single root canal were included .After crown remov-al and root canal preparation,96 teeth were randomly divided into 4 groups (n=24):A (AH-plus),M (MTA),I (IRoot)and E(Endosequence).And each group were further divided into 4 sub-groups:D(Dry),L(Less dry),m (Moist)and W(Wet).The remaining 16 teeth were used as positive and negative controls respectively .The root canals were filled with corresponding sealants by warm gutta-percha after different drying procedures.Micro-leakage was assessed by ink staining 7 d after canal filling.RESULTS:The mean depth of ink dye penetration of AH-plus was the minimum under dry condition in contrast to MTA and Endosequence (P<0.05).The mean depth of ink dye penetra-tion of IRoot was the minimum under wet condition in contrast to AH-plus and MTA (P<0.05 ).CONCLUSION:The closure property of IRoot and Endosequence is better than that of AH-plus and MTA under moist and wet root canal conditions.
