Perforation Repair Using Mineral Trioxide Aggregate - Case Report

ABSTRACT

Root perforations affect the prognosis of teeth. Inadequacy of the repair materials has been a contributing factor to the poor outcome of repair procedures. Mineral trioxide aggregate (MTA) is a new material that is being successfully used to repair perforations. The purpose of this study was to evaluate the success rate of root perforation repair using MTA. Pre-treatment and post treatment and at least 1 year follow-up radiographs were evaluated to determine the presence or absence of any pathologic changes adjacent to the perforation site. The result showed normal tissue architecture adjacent to the repair site at the recall visit. Teeth with existing lesions showed resolution of the lesion. Based on the result of this study, MTAprovides an effective seal of root perforations and improve the prognosis of perforated teeth that would otherwise be compromised.
