CLINICAL RESEARCHRepair of Root Perforations Using Mineral Trioxide Aggregate: A Long-term Study
Section snippets
MATERIALS AND METHODS
A cross-referenced list was obtained of all patients seen at the Loma Linda University endodontic residency program who were treated with MTA. From this list, patients were chosen based on the following criteria: presence of a root perforation that had been repaired with MTA with accompanying radiographs documenting the tooth at the time of treatment and a minimum of 1 year of postoperative follow-up. All patients from the list meeting these criteria were included in the study. There were 16
RESULTS
Of the 16 clinical cases that were included in this study, five were classified as lateral perforations (Fig. 1), five as strip perforations (Fig. 2), three as furcal perforations (Fig. 3), and three as apical perforations (Fig. 4). None of the teeth had pocket measurements greater than 3 mm. Seven of these patients presented with radiolucent lesions at the time of repair. The follow-up radiographs ranged from 12 to 45 months. All of the cases with evidence of preoperative radiolucency
DISCUSSION
Although MTA is one of the most researched materials in dentistry, showing remarkable results, the majority of the published data are based on in vitro and animal studies. Research must be continued to evaluate clinical outcomes in human subjects. The importance of clinical data is substantiated by recent trends in evidence-based dentistry. In this article, we present a series of cases that have demonstrated consistent healing with the use of MTA as a perforation repair material. The
