What is the main purpose of using corticosteroids in pulpal obturation material?

The primary purpose of using corticosteroids in pulpal obturation material is for their anti-inflammatory action. Corticosteroids are potent anti-inflammatories that help reduce inflammation in the tooth pulp, which is crucial in managing pulpal tissue responses during dental procedures. When inflammation occurs in the dental pulp, it can lead to pain and further complications. By incorporating corticosteroids into the obturation material, the inflammation can be managed more effectively, leading to improved outcomes in the treatment of pulpal diseases.

The role of corticosteroids is particularly significant in cases where there is a risk of persistent inflammation, as controlling this aspect can help promote healing and reduce the chances of the condition escalating. While other options may involve elements relevant to dental treatment, such as potential pain relief or enhancing sealing ability, they do not specifically address the primary therapeutic action of corticosteroids in this context.
