矿物三氧化物聚集体（MTA）粘固剂用于直接盖髓和许多其它应用中，并且这些产品的几种类型已经商业化。本研究的目的是研究三种传统MTA骨水泥和一种树脂改性MTA骨水泥的抗菌效果和矿物诱导能力。琼脂扩散试验显示，凝固后，所有四种骨水泥对粪肠球菌和变形链球菌几乎没有抗菌作用，材料之间没有显著差异。24 h后，E. faecalis和S.与没有任何粘固剂的情况下培养的相同细菌悬浮液相比，在每种粘固剂存在下培养的变形菌悬浮液没有表现出活细菌数量的减少;这表明没有一种粘固剂抑制细菌生长。此外，树脂改性MTA水泥表现出较低的矿物诱导能力，与三个传统的MTA水泥相比。
Mineral trioxide aggregate (MTA) cements are used in direct pulp capping and many other applications, and several types of these products have been commercialized. The aim of this study was to examine the antibacterial effects and mineral induction abilities of three conventional MTA cements and one resin-modified MTA cement. Agar diffusion tests revealed that, after setting, all four cements exhibited little antibacterial effects against Enterococcus faecalis and Streptococcus mutans, with no significant differences among the materials. After 24 h, E. faecalis and S. mutans suspensions incubated in the presence of each cement did not exhibit reduced numbers of viable bacteria, compared with those same bacterial suspensions incubated without any cement; this indicated that none of the cements inhibited bacterial growth. Furthermore, the resin-modified MTA cement exhibited lower mineral induction ability, compared with that of the three conventional MTA cements.
