What makes calcium hydroxide beneficial in dentistry?

Calcium hydroxide is beneficial in dentistry primarily because it helps kill caries bacteria. Its antimicrobial properties make it an excellent choice for use in procedures where bacteria need to be eliminated, such as in the preparation of cavities or during root canal treatments. Furthermore, calcium hydroxide promotes the formation of secondary dentin and provides an alkaline environment that is unfavorable for bacterial growth, enhancing its effectiveness in managing pulp health and preventing further decay.

While it is important to note that calcium hydroxide has various applications in dentistry, it is typically not used as a permanent restoration material, which is why this does not represent its core benefit. Also, it has a relatively fast setting time compared to other materials, and while it may sometimes be used temporarily, it is not considered impractical for temporary uses in specific situations, such as in pulpotomy procedures.
