5. Conclusions
- (1)
- AH Plus showed significantly higher push-out bonding strength amongst all experimental groups, regardless of the obturation techniques used.
- (2)
- AH Plus, when used especially in cold lateral compaction technique, significantly proved to show the highest push-out bonding strength values amongst all experimental groups.
- (3)
- Endosequence BC Sealer proved to be weaker in bonding strength when compared to AH Plus sealer, regardless of the obturation techniques used.
- (4)
- The bonding strength of Endosequence BC Sealer is even more weakened in-conjuction-with thermo-plasticized injectable technique with Calamus Flow Delivery System—however, there was no significant difference between the two Endosequence BC Sealer groups.
