Comparison of apical sealing ability of continuous wave of obturation technique using EndoTwinn and System B

The role of obturation in root canal treatment, although considered secondary to debridement and disinfection, still remains a critical stage for a successful outcome. The aim of obturation is to seal the periradicular tissues from the residual microorganisms left in the root canal system after chemomechanical debridement. Obturation of the root canal space has been performed using various techniques. The most commonly used and tested technique is cold lateral condensation. But cold lateral condensation offers the disadvantage of lacking of homogeneity and relying on spreader to fill the voids between the individual cones. The technique of vertically compacting warm * Corresponding Author: Hyeon-Cheol Kim
