    Advantages of MTA
    – High biocompatibility
    – Hydrophilic
    – Radio-opaque
    – Highly alkaline pH (Bacteriostatic)
    – Excellent sealing ability (Low marginal leakage)
    – Low solubility

    What’s so Unique About MTA?
    Materials used to repair perforations, seal the retro-preparation in surgical endodontics, close open apices or to protect the pulp in direct pulp capping, are inevitably in contact with blood and other tissue fluids. This moisturizing effect may be an important factor that has major effects on the physical properties and sealing abilities of the restorative materials. MTA is however not affected by moisture or blood contamination: The presence or absence of blood seems not to affect the sealing ability of the mineral trioxide aggregate.
