Direct pulp capping (DPC) is indicated for a tooth with a small pulpal exposure that occurs within 24-72 hours, with only a small portion of diseased pulp removed. Which procedure is this?

Direct pulp capping (DPC) is indicated for a tooth with a small pulpal exposure that occurs within 24-72 hours, with only a small portion of diseased pulp removed. Which procedure is this?

• A. Apexogenesis
• B. Cvek pulpotomy
• C. Pulpectomy
• D. Direct pulp capping (DPC)

Answer: (D)

Preserving pulp vitality by sealing directly over a small pulpal exposure is the key idea. When a tiny exposure occurs and the pulp is largely healthy or only minimally inflamed, and treatment starts soon after (roughly within 24–72 hours), direct pulp capping is the best option. The aim is to place a biocompatible material directly on the exposed pulp to seal it from bacteria and stimulate healing, encouraging the formation of a dentin bridge and keeping the pulp alive for continued tooth function. Materials like calcium hydroxide or a calcium silicate cement are used, followed by a definitive restoration to prevent microleakage. This approach wouldn’t involve removing pulp tissue, which is why it fits a scenario with a small, recent exposure and a relatively healthy pulp. If there were more extensive inflammation or the exposure had been longer, other procedures such as removing inflamed coronal pulp tissue (partial pulpotomy) or removing all pulp tissue (pulpectomy) might be considered. Apexogenesis, on the other hand, aims to encourage continued root development in immature teeth, not simply seal a small exposure.
