Abstract
Aim: To compare the post-operative pain level after three different time intervals following single-visit endodontic treatment in cases with symptomatic irreversible pulpitis teeth using manual dynamic agitation as a final irrigation protocol.
Methodology: 22 Teeth were anaesthetized using a nerve block technique, Access was performed with Z and round bur.Length was determined using apex locator. Canals were prepared with crown down technique using Fanta rotary files with an endo motor. Canals were thoroughly irrigated with a syringe with end needle gauge 27, delivering 5 ml of 2.5% NaOCl at each instrument change and finally irrigated with manual dynamic agitation, the irrigant was manually activated for 60 seconds with a master cone for each canal. The canals were dried with sterile paper points equal to the size of the master cone. Root canals were obturated using lateral compaction technique, by gutta percha master cone equal to the size of the master apical file and a spreader was used to make space for auxiliary cones, using resin root canal sealer then placing temporary filling and then a spreader was used to allow space for auxiliary cones, using resin-based root canal sealer i then placing temporary filling.
