进行了一项回顾性研究，比较了使用三种不同根端填充材料的牙齿的成功率。研究的材料有 SuperEBA、IRM 和无锌高铜球形汞合金。使用了来自两个不同地理位置的办公室的 488 个病例的射线照片，回顾期从最短 6 个月到最长 10 年不等。每个办公室的案件均使用相同的标准进行独立审查。结果显示，与汞合金相比，SuperEBA 和 IRM 在成功率方面均表现出统计上显着的提高。汞合金的成功率为 75%，IRM 的成功率为 91%，SuperEBA 的成功率为 95%。 IRM 和 SuperEBA 之间的差异没有统计学意义。
A retrospective study was done to compare the success rates of teeth with three different root end filling materials. The materials studied were SuperEBA, IRM, and zinc-free high-copper spherical amalgam. Radiographs of 488 cases from two geographically distinct offices were used, with the recall period ranging from a minimum of 6 months to a maximum of 10 yr. The cases in each office were examined independently using the same criteria. The results revealed that both SuperEBA and IRM demonstrated statistically significant improvements in success rates when compared with amalgam. The success rates were 75% for amalgam, 91% for IRM, and 95% for SuperEBA. The difference between IRM and SuperEBA was not statistically significant.
