- Perforation repairs
- Resorption repairs
- Pulp Capping
Features
- Sealability
- Biocompatibility
- Sets in presence of moisture
Benefits

*Conclusion: This study showed that MTA had significantly less leakage than IRM or amalgam. MTA also showed the least overfilling tendency while IRM showed the least underfilling tendency.

*Conclusion: The purpose of this study was to evaluate the ability of MTA and amalgam to seal furcal perforations in extracted human molars using an anaerobic bacterial leakage model. Eight of the amalgam samples leaked, whereas none of the 18 MTA samples leaked.

*Conclusion: This study examined the dental pulp responses in monkeys to MTA and a calcium hydroxide preparation when used as a pulp-capping material. The study showed no pulpal inflammation in 5 of 6 samples capped with MTA and a complete dentin bridge in all samples using MTA. All pulps capped with the calcium hydroxide preparation showed pulpal inflammation while bridge formation occurred in only two samples.

*Conclusion: This study suggests that MTA is a far more suitable material than amalgam for perforation repair, particularly when used immediately after perforation.
