| | Ortho MTA | 200/0.2 | 180 min | 360 min | BioMTA (South Korea) | Calcium carbonate (60∼80), silicon dioxide (5∼15), aluminium oxide (5∼10), and dibismuth trioxide (10∼30) |
| | ProRoot MTA | 500/0.167 | 78 min (±5 min) | 261 min (±21 min) | Dentsply (USA) | Portland cement (60∼90) and bismuth oxide (10∼40) |
| | MTA Angelus | 140/0.467 | 10 min | 15 min | Londrina (Brazil) | Tricalcium silicate (45∼60), dicalcium silicate (5∼12), tricalcium aluminate (5∼12), tetracalcium aluminoferrite (1∼7), calcium oxide (0∼7), and bismuth oxide (15∼30) |
