The success of endodontic treatment depends on the apical seal. Root canal sealer placement plays an important role in achieving hermetic apical seal. The effectiveness of sealer placement depends on placement technique, viscosity of sealer, canal configuration, quality of canal debridement, and size of instrumentation. In this study, efficacy of traditional sealer placement techniques is compared with bidirectional sealer using resin-based sealer. Forty-four human anterior teeth with straight canals were selected and prepared with step back method. These specimens were divided into four groups of 10 specimens each and obturated by using four different methods of sealer placement techniques with single master cone and access cavity sealed with amalgam. Results of the study suggest that best sealer coverage was provided by lentulospiral and bidirectional spiral. Bidirectional spiral prevents the apical extrusion of the sealer and thus periapical irritation, which commonly occurs with the other three methods. Bidirectional spiral has more success in filling of the lateral canal than the other techniques.
