<br/><br/> Aim: The present study was conducted to compare the push-out bond strength and marginal adaptation of mineral trioxide aggregate (MTA) and Bio Aggregate (BA) as root-end filling materials at three different evaluation periods; 3 days, 2 weeks and two months. Materials and Method: A total of sixty-six extracted human maxillary incisors were used in this studyRoot-end resection perpendicular to the long axis of the root was made on each tooth
