N2  - This present study was conducted to shed a light on the importance of activation
of irrigation during root canal therapy and it’s effect on reduction of postoperative
pain.
78 patients were selected randomly with necrotic teeth with symptomatic apical
periodontitis and they are divided into 3 groups according to the method of
irrigation activation after root canal preparation with protaper Next.
Group (A): irrigation by Navi-tip –side vented needle of 31-gauge, 27mm.
Group (B): irrigtion activation was done by XP-Endo Finisher
Group (C): irrigation activation was done using ultrasonic device (Ultra X)
? Each group received the root canal treatment in a single visit.
? Pain was evaluated at time intervals of 6-12-24-72 hours and 7 days by the
help of visual analogue scale (VAS).
? At the first day (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 day 7.
? The amount of analgesics taken by the patients were higher at the first 48 hours among all groups.
- Patient at group A recorded the highest amount of analgesics intake at the
first 24 hours.
- At (48-72 hours and 7 days) there were no significant difference between
the groups where the number of analgesics intake decrease
