Antibacterial activities and mineral induction abilities of proprietary MTA cements

Mineral trioxide aggregate (MTA) cements are used in direct pulp capping and many other applications, several types of these products have been commercialized. The aim this study was to examine the antibacterial effects mineral induction abilities three conventional MTA one resin-modified cement. Agar diffusion tests revealed that, after setting, all four exhibited little against Enterococcus faecalis Streptococcus mutans, with no significant differences among materials. After 24 h, E. S. mutans suspensions incubated presence each cement did not exhibit reduced numbers viable bacteria, compared those same bacterial without any cement; indicated that none inhibited growth. Furthermore, lower ability, cements.
