Which dental material is known for its ability to promote healing in the pulp area?

Calcium hydroxide is recognized for its unique properties that promote healing in the pulp area. This material has alkaline pH which helps stimulate the reparative dentin formation when placed over pulp exposure. It's particularly effective in direct pulp capping procedures because it aids in creating a favorable environment for the pulp to heal. Additionally, calcium hydroxide has antibacterial properties, further contributing to its effectiveness in pulp treatments by reducing the risk of infection.

In contrast, zinc phosphate cement is primarily used as a base or luting agent but does not possess intrinsic healing properties. Zinc oxide-eugenol is often used for its soothing effects on the pulp and as an obtundent but is not as effective in promoting pulp healing as calcium hydroxide. Amalgam, while a durable restorative material, does not interact with the pulp in a way that promotes healing. Thus, calcium hydroxide stands out for its essential role in pulp therapy and regenerative treatment within dentistry.
