Summary
Mineral trioxide aggregate (MTA) effectively seals root perforations, improving tooth prognosis. This study found MTA repairs led to normal tissue architecture and lesion resolution in all evaluated cases.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Root perforations negatively impact tooth prognosis.
- Inadequate repair materials contribute to poor outcomes.
- Mineral trioxide aggregate (MTA) shows promise for perforation repair.
Purpose of the Study:
- To evaluate the success rate of root perforation repairs using MTA.
- To assess the clinical and radiographic outcomes of MTA in repairing root perforations.
Main Methods:
- Retrospective analysis of 16 cases of root perforation repair with MTA.
- Double-blind evaluation of pretreatment, posttreatment, and 1-year follow-up radiographs.
- Assessment for pathologic changes adjacent to the perforation site.
Main Results:
- All 16 cases demonstrated normal tissue architecture at follow-up.
- Existing periapical lesions resolved post-MTA repair.
- Teeth without preoperative lesions remained lesion-free.
Conclusions:
- MTA provides an effective seal for root perforations.
- MTA shows significant promise in improving the prognosis of teeth with root perforations.
