Mineral Trioxide Aggregate may be the most effective direct pulp capping material

ConclusionsMTA was more effective than CH at hard-tissue barrier formation, and MTA had better effects than CH in capping mechanical pulp exposures. The use of a bonding agent as a pulp capping material produced inferior results compared to CH. More RCTs with larger sample sizes should be conducted to further strengthen these conclusions, and future studies should also test the quality of dentinal bridges formed, not only the positive or negative presence.
