Comparison of Post-operative Pain After Use of Endo-activator and Conventional Irrigation During Endodontic Treatment in Symptomatic Periapical Periodontitis

Introduction: The adequate removal of microorganisms, infected or necrotic pulp tissues and complete adequate seal of root canal system along with debridement is key to success of endodontic treatment. The objective of this study was to compare frequency of pain after using Endo Activator and conventional irrigation in patients presenting with symptomatic periapical periodontitis following endodontic treatment by means of Visual Analog Scale. Methods: This study was designed as single blind, randomized control trial. Sixty patients with symptomatic teeth requiring endodontic canal treatment were recruited by probability random sampling into two groups based on irrigation protocols used during endodontic treatment: conventional needle and endo activator irrigation system. The post-operative pain of patients was recorded via a telephone call at 6 hours, 24 hours, and at 7 days on the visual analogue scale (VAS).
