What is the main reason for using calcium hydroxide in dental procedures?

The main reason for using calcium hydroxide in dental procedures is related to its role in pulp capping. Calcium hydroxide is a vital material in endodontics because it promotes the formation of reparative dentin, which is essential in protecting the dental pulp when the tooth is exposed or at risk of necrosis. This material is placed over the pulp or at the site of the cavity to create a barrier that facilitates healing and maintains pulp vitality.

Its properties, such as high pH and the ability to encourage the regeneration of dental tissue, make calcium hydroxide particularly effective for this purpose. It also has antibacterial properties, contributing to its effectiveness in preventing infection during procedures where the pulp is at risk.

While calcium hydroxide can also play a role in reducing pain due to its soothing effect on the pulp, enhancing bonding, or purely for aesthetic reasons are not the primary functions of this compound in dental practices. The reason for its application as pulp capping underscores its importance in supporting tooth health and maintaining patient comfort during treatment.
