In vitro evaluation of two methods of ultrasonic irrigation on marginal adaptation of MTA plugs in open apex teeth: a SEM analysis.

Context: Different factors can affect the marginal adaptation of MTA.

Aims: The present study was designed to investigate the effect of two ultrasonic irrigation methods on the marginal adaptation of MTA plug in open apex teeth by scanning electron microscope.

Settings And Design: Thirty single mature teeth were included in this in vitro experimental prospective study.
