Apical plug technique using mineral trioxide aggregate: results from a case series.

AIM: To examine the clinical and radiographic appearance of teeth that suffered premature interruption of root development and were treated by an mineral trioxide aggregate (MTA) apical plug technique. SUMMARY: Eleven teeth with immature root apices in 11 patients were treated nonsurgically by the manual application of MTA in the apical portion of the root canal under microscopic vision. Follow-up evaluations were performed at 1-2 years after treatment. KEY LEARNING POINTS: Mineral trioxide aggregate appears to be a valid material to obtain periradicular healing in teeth with open apices and necrotic pulps. Ten out of 11 cases were associated with periradicular health at follow-up evaluation.
