Etiology

In few cases, the pulp may get exposed either due to dental caries, dental trauma or as a result of iatrogenic errors during operative procedures.

How does direct pulp capping work?

In cases where the dental pulp is exposed, direct pulp capping is a technique for treating an exposed dental pulp with a material that seals the exposure site and promotes reparative dentin formation.<ref>Komabayashi T, Zhu Q, Eberhart R, Imai Y.

Criteria for Direct pulp capping

• The tooth must be asymptomatic before the exposure i.e., no spontaneous pain, or abnormal response to thermal stimuli.
• The size of the exposure must be small - less than 0.5mm in diameter.
• Hemorrhage from the exposed pulp must be easy to control.
• The area of the exposure must be uncontaminated by saliva or gingival fluid.

Materials Used

• Calcium hydroxide
• Mineral trioxide aggregate (MTA)
