Objective:
To observe the clinical effect of iatrogenic perforation repaired by mineral trioxide aggregate (MTA).
Methods:
Twenty-one iatrogenic perforation cases were included. The root canals were shaped and cleaned and then obturated after MTA was used to repair the perforation with microscopes. Preoperative, immediate postoperative, and follow-up radiographs were evaluated to determine the pathologic changes adjacent to the perforation site.
Results:
Nineteen cases healed and two cases were healing. No cases failed.
Conclusions:
MTA is effective in the treatment of iatrogenic perforation.
