Comparison of Postoperative Pain After Root Canal Irrigation in Symptomatic Irreversible Pulpitis

This randomized controlled trial will compare postoperative pain following root canal treatment in patients with symptomatic irreversible pulpitis. The study will evaluate whether using dexamethasone as the final intracanal rinse provides better pain control than normal saline. Patients requiring two-visit root canal treatment for symptomatic irreversible pulpitis will be randomly assigned to receive either dexamethasone or normal saline as the final rinse during root canal treatment. All participants will otherwise receive the standard root canal treatment protocol. Postoperative pain will be assessed using a Visual Analog Scale (VAS) at the specified follow-up time points after treatment. Pain scores between the two groups will be compared to determine whether the addition of dexamethasone as a final intracanal rinse reduces postoperative pain.
