Influence of Apical Patency Concept Upon Postoperative Pain After Root Canal Treatment

In Gp A, apical patency will be maintained till obturation using electronic apex locator confirmed radiographically. Finally, Root canals will be obturated using cold lateral compaction technique. The molars will be permanently restored using composite resin restoration and will be scheduled for extra coronal restoration.

in Gp B apical patency will not be maintained. Finally, Root canals will be obturated using cold lateral compaction technique. The molars will be permanently restored using composite resin restoration and will be scheduled for extra coronal restoration
