Aim: This clinical study was designated to evaluate the influence of three root canal irrigation activation methods on post-operative pain using the Visual analogue scale VAS. Material and Methods: 78 patients having symptomatic irreversible pulpitis in mandibular first molar with no periapical involvement. ProTaper Next rotary files were used for root canal preparation, then randomized into three equal groups according to the technique used for final irrigation agitation technique where each group have 26 cases (n=26 ) . Group A: received irrigation with 2.6% sodium hypochlorite with NaviTip (31-gauge 27 mm) with double side port irrigator tip (SVN) without any agitation ; Group B: received irrigation with 2.6% sodium hypochlorite with final mechanical agitation of irrigation with ultrasonic device activation (Endo ultra)(PUI) Group C:received irrigation with 2.6% sodium hypochlorite with final mechanical agitation of irrigation with sonic
device activation (EDDY). Postoperative pain was evaluated at time intervals of 6-12-24-72 hours and 7 days by the help of visual analogue scale (VAS) Results: Overall results of study showed ,At the first (6-12-24 hours) there was a significant difference between the groups in pain incidence and intensity where group A showed more pain scores than group B and group C. At (48-72 hours and 7 days) there were no significant difference between the groups where pain scores declined among the groups till it reaches nearly score (0) at 7 day. Conclusion: group A (SVN) showed highest postoperative pain in the first 24 hours in comparison with the other groups, where the pain level decreased gradually in all groups after 24 hours.
