abstract：:Type IV matrix metalloproteinases (MMPs) are members of the family of MMPs and are thought to play an important role in degradation of extracellular components. Human pulp cells can secrete and produce these enzymes. Recent evidence shows that MMPs may play a role in pulpal inflammation. To date little is known regard...
