Abstract

AIM:To investigate the effect of apical barrier and perforation repair with Mineral Trioxide Aggregate (MTA).METHODS:Eleven cases were carried out endodontic therapy.In which MTA was used to manage clinical problems.Seven cases were treated with MTA to develop apical barrier.Each case had a pulpless permanent tooth with blunderbuss open apex.The MTA plug was created under operative microscope.The root canal space was obturated with vertical condensation.The treatment required only one or two visits.In other four cases (five teeth) the perforation in furcation or root was repaired with MTA.Eleven cases have varying follow-up periods from six months to more than four years.RESULTS:In each case,MTA allowed bone healing and elimination of clilnical symptoms.CONCLUSION:MTA may be an ideal material for perforation repair and achieving apical seal in tooth with immature apex.
