ABSTRACT
A Parallel Randomized Clinical Trial To Answer Clinical Question In Patients Having Non-vital Teeth With Apical Periodontitis Would Triple Antibiotic Paste Root Canal Disinfectant In Comparison To Calcium Hydroxide Root Canal Disinfectant Differ In Postoperative Pain. Thirty-eight Medically Free Participants Who Had Non-vital Single Rooted Teeth With Apical Periodontitis Were Randomly Assigned Into Two Equal Groups According To The Root Canal Disinfectant To Be Used, Either Calcium Hydroxide (group A), Or Triple Antibiotic Paste (group B). Root Canal Treatment Was Completed In Two Visits; In The First Visit Root Canal Shaping And Cleaning Was Performed, Root Canal Disinfectant Placed, And Each Participant Was Scheduled For A Second Appointment To Complete Root Canal Therapy After 2 Weeks. Postoperative Pain Was Measured Using A Numerical Rating Scale (NRS) At 4, 24, 48, 72 And 96 Hours After Initial Visit. Results Showed That Through The Whole Study Period; There Was No Statistically Significant Difference Between Mean Pain Scores In The Two Groups. It Could Be Concluded That The Use Of Root Canal Disinfectant Either Calcium Hydroxide Or Triple Antibiotic Paste In Non-vital Teeth With Apical Periodontitis Reduced Postoperative Pain.
