Abstract
Introduction
The use of biocompatible materials like mineral trioxide aggregate (MTA) may improve
the prognosis of teeth with root perforations.
Methods
The treatment outcome of root perforations repaired between 2000 and 2006 with MTA
was investigated. Twenty-six patients received treatment with MTA in 26 teeth with
root perforations. Treatment was performed by supervised undergraduate students (29%),
general dentists (52%), or dentists who had focused on endodontics (19%). Perforation
repair by all treatment providers was performed using a dental operating microscope.
Calibrated examiners assessed clinical and radiographic outcome 12 to 65 months after
treatment (median 33 months, 81% recall rate). Pre-, intra-, and postoperative information
relating to potential prognostic factors was evaluated.
Results
Of 21 teeth examined, 18 teeth (86%) were classified as healed. None of the analyzed
potential prognostic factors had a significant effect on the outcome.
Conclusions
MTA appears to provide a biocompatible and long-term effective seal for root perforations
in all parts of the root.
