Results showed that mechanical active irrigation reduces post-operative pain .
It improved debridement , canal/isthmus cleanliness .
It also improved delivery of irrigant up to working length .
Bacterial count was more with active irrigation , though not significant .
There is no effect on long-term periapical healing .
Conclusion It may be concluded that mechanical active irrigation devices are beneficial in reducing post-operative pain and improving canal and isthmus cleanliness during Endodontics
Objective Irrigant activation has been cl aim ed to be beneficial in in vitro and clinical studies .

The Effect of Different Irrigation Agitation Techniques on Postoperative Pain in Mandibular Molar Teeth with Symptomatic Irreversible Pulpitis: A Randomized Clinical Trial
Introduction This study compared the effect of several final irrigation agitation techniques ( sonic agitation , passive ultrasonic irrigation , and manual dynamic agitation [ MDA ] ) in comparison with needle irrigation on postoperative pain in m and ibular molar teeth with symptomatic irreversible pulpitis . Methods One hundred sixty‐eight patients with a single tooth diagnosed as symptomatic irreversible pulpitis were selected . Teeth were r and omly assigned to 4 groups based on the final irrigation methods . In group 1 ( needle irrigation ) , irrigation was conducted without agitation with a side‐port needle ; in group 2 , sonic agitation was used ; in group 3 , passive ultrasonic irrigation was used ; and in group 4 , MDA was used . Teeth were then obturated with gutta‐percha and a resin‐based sealer using the cold lateral compaction technique .  The presence of postoperative pain was assessed after 6 , 24 , 48 , and 72 hours and 1 week . Results At the 6‐ and 24‐hour time intervals , group 4 patients reported more intense postoperative pain than those patients in groups 1 , 2 , and 3 ( P < .05 ) . There was no significant difference among the groups at the other time intervals ( P > .05 ) , and in all groups the intensity of postoperative pain decreased over time . Conclusions MDA caused greater postoperative pain after endodontic therapy in m and ibular molar teeth with symptomatic irreversible pulpitis compared with the other methods in the first 24 hours
