Direct pulp capping (DPC) is a treatment performed when a pin-point or small pulp exposure of 1mm or less occurs after removal of carious tooth material (dentin) excavation. The pulp is covered with a medicament. This technique has limited use when pulp is exposed due to injury but is generally not accepted for managing carious pulp exposures in primary teeth, as it has been shown to have limited success. Medicaments used in DPC include calcium hydroxide and alternates such as mineral trioxide aggregate (MTA).
