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.
开展了一项回顾性研究，以比较使用三种不同根充材料的牙齿的成功率。所研究的材料为SuperEBA、IRM和无锌高铜球形银汞合金。使用了来自两个地理位置不同的诊所的488例病例的X光片，召回期最短为6个月，最长为10年。每个诊所的病例均使用相同的标准进行独立检查。结果显示，与银汞合金相比，SuperEBA和IRM的成功率均有统计学上的显著提高。银汞合金的成功率为75%，IRM为91%，SuperEBA为95%。IRM和SuperEBA之间的差异无统计学意义。
