Objective: To compare postoperative pain levels following root canal therapy using EndoActivator sonic irrigation versus conventional syringe irrigation in posterior molars.
Study Design: Randomized controlled trial (ClinicalTrials.gov (NCT07062419).
Place and Duration of Study: Department of Operative Dentistry, 28-Military Dental Centre, Combined Military Hospital, Lahore Pakistan, from Aug 2024 to Jan 2025.
Methodology: Fifty-eight patients aged 18–60 years, diagnosed with symptomatic or asymptomatic apical periodontitis, were randomly allocated into two groups: Group-A (Conventional syringe irrigation, Control) and Group-B (EndoActivator sonic irrigation, Experimental). Post-operative pain was measured using the Numerical Rating Scale (NRS) at 24, 36, and 48 hours.
Results: There was no statistically significant difference in post-operative pain levels between the groups at any time point. At 24 hours, 34% of patients in the EndoActivator Group-And 27% in the control group reported no pain (p=0.321). By 48 hours, 86.67% of patients in both groups were pain-free (p=1.000).
Conclusion: Both EndoActivator and conventional syringe irrigation techniques yielded comparable post-operative pain outcomes. Selection of irrigation technique should be based on factors such as procedural efficiency and patient comfort rather than pain reduction alone.
