In this case report, a 19-year-old female patient with a second premolar with irreversible pulpitis and symptomatic apical periodontitis was treated with MTA pulpotomy. Follow-up electric pulp tests showed viability of the tooth at

Microscopically, the pulpal wound treated with MTA was free from inflammation and covered with a thin layer of reparative dentin. The authors conclude that, when caries and bacterial contamination can be removed from the dentin-pulp complex, the inflamed but vital pulp of a permanent tooth may have a chance to return to a healthy, functional status after MTA pulpotomy. When caries and bacterial contamination can be mostly eliminated from the dentin-pulp complex, the inflamed pulp of a human permanent tooth with irreversible pulpitis may have a chance to return to a healthy and functional status after mineral trioxide aggregate pulpotomy.
