introduction: mineral trioxide aggregate (mta) has been suggested as an effective material for apical barrier, forming an effective seal against bacterial leakage in teeth with open apices. mta needs moisture for setting; which can come from the apical region or a moist cotton pellet. this study was intended to compare bacterial leakage in one- and two-step mta apical barrier technique in open ...
