<br/><br/> The purpose of this study was to compare the fracture resistance of immature roots having apical plug with Portland cement ( PC ) together with obturation using ( i ) Zinc Oxide based sealer (ii) Epoxy resin based sealer used with lateral compaction of gutta - percha ( iii ) Total oburation with Portland cement . Twenty five single rooted teeth were randomly assigned into three experimental groups according to the filling material and one control group
