The aim of this study was to assess the effect of three different root canal irrigation solutions on the apical sealing ability of three different root canal obturation materials: gutta-percha with AH plus or MM-seal and Resilon with Epiphany SE.
Each irrigation group was further divided into three groups according to the use of three different root canal obturation materials (n = 10): Gutta-percha with AH plus (Dentsply, Konstanz, Germany) or MMseal (Micro-Mega, Besangon, France), Resilon with Epiphany SE (Pentron Clinical Technologies, Wall ingford, CT, USA).
Root canal obturations were done with lateral condensation using AH 26 root canal sealer (DentsplyMaillefer, Tulsa, Ok, US) and gutta percha.
