The goal of this clinical trial is to learn whether probiotics, double antibiotic paste (DAP), or calcium hydroxide paste help reduce postoperative pain after root canal treatment in adults with symptomatic irreversible pulpitis. It will also learn about the safety of these medicaments. The main questions it aims to answer are: Do probiotics, DAP, or calcium hydroxide lower the amount of pain patients experience after the first visit of root canal treatment? What medical problems or side effects do participants experience when any of these medicaments are used? Researchers will compare probiotics, DAP, and calcium hydroxide to see which one works best to control postoperative pain. Participants will: Receive one of the three intracanal medicaments (probiotics, DAP, or Ca(OH)â‚‚) placed inside their root canal Visit the clinic for follow-ups according to the treatment plan Report their pain levels using a Visual Analog Scale (VAS) at several time points (before treatment, 12 hrs, 24 hrs, 48 hrs, 3 days, and 7 days) Inform the research team about any discomfort, symptoms, or side effects during the week after treatment
