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 Apical Positive and Negative Pressure Irrigation Methods on Postoperative Pain in Mandibular Molar Teeth with Symptomatic Irreversible Pulpitis: A Randomized Clinical Trial
Introduction : This study compared the effect of conventional needle irrigation ( positive pressure ) and the EndoVac system ( Discus Dental , Culver City , CA ) ( negative pressure ) on postoperative pain in m and ibular molar teeth with symptomatic irreversible pulpitis . Methods : One hundred sixteen patients with symptomatic irreversible pulpitis were selected . Teeth were r and omly assigned to 2 groups according to the irrigation methods performed during root canal preparation . In group 1 , root canal irrigation was performed using a syringe and a 31‐G side‐port needle ( NaviTip ; Ultradent , South Jordan , UT ) . In group 2 , the EndoVac system was used for irrigation . 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 6‐ , 24‐ , and 48‐hour time intervals , group 1 patients reported more intense postoperative pain than patients in group 2 ( P < .05 ) . There was no significant difference between the 2 groups at the other time intervals ( P > .05 ) , and in both groups the intensity of postoperative pain decreased over time . Conclusions : Apical positive pressure irrigation caused greater postoperative pain after endodontic therapy of m and ibular molar teeth with symptomatic irreversible pulpitis compared with the apical negative pressure irrigation system
