Which treatment option seems to decrease periradicular inflammation caused by the extrusion of root canal filling materials?

Dexamethasone is a corticosteroid known for its potent anti-inflammatory properties. In the context of periradicular inflammation, which can occur after the extrusion of root canal filling materials, dexamethasone helps reduce inflammation by suppressing the immune response and inhibiting various inflammatory mediators. This can lead to decreased swelling, pain relief, and an overall reduction of inflammation in the periradicular tissues.

While other options may have their respective uses, such as pain relief (analgesics) or temporary symptom management (cold packs), they do not directly target the underlying inflammatory processes to the extent that a corticosteroid like dexamethasone does. Antibiotics, on the other hand, are effective against bacterial infections but do not have a significant effect on inflammation caused by the extrusion of materials. Thus, dexamethasone is the treatment choice that specifically addresses periradicular inflammation effectively.
