Metaanalysis of filler materials in periapical surgery

Our purpose was to evaluate the success and failure, apical sealing and biocompatibility of silver amalgam, IRM®, SuperEBA® and MTA as retrograde filler materials. A metaanalysis was made of filler materials in periapical surgery, evaluating a total of 30 articles published in recent years. Percentage success with silver amalgam was 76.5% and slightly inferior to that afforded by IRM®. Performance in turn increased considerably when the materials used were SuperEBA® or MTA. As regards marginal leakage, MTA with a mean leakage time of 65.5 days afforded the best results, followed by SuperEBA®, IRM® and silver amalgam. MTA was the most biocompatible of the materials studied, with practically …
