Background: One of the main reasons for post endodontic pain is the polymicrobial intracanal flora that may survive the initial disinfection. A single antimicrobial agent might not provide adequate disinfection, and an antimicrobial combination such as triple antibiotic paste was tested to achieve this goal. Aim: The study aimed to assess the efficacy of three intra-canal medicaments on post root canal preparation pain. Materials and Methods: Eighty patients with single-rooted necrotic teeth and symptomatic apical periodontitis were randomly assigned to four treatment groups (Pain of endodontic origin is an undesirable event for both the patient and clinician. It has been estimated that 80% of patients who have pre-operative tooth ache continue to feel pain after endodontic treatment. Post-treatment pain is generally mild, and settles down within 72 hrs with analgesics such as NSAIDS or Acetaminophen [An array of intra-canal medications is utilized in contemporary endodontic practice. One of these intra-canal medications is calcium hydroxide (CH). CH is employed as a multipurpose medicament in endodontic therapy, and is effective in alleviating pain by lowering the concentration of inflammatory exudates [The present study aimed to evaluate the efficacy of three intra-canal medicaments on post root canal preparation pain in teeth with symptomatic apical periodontitis. This single-blind randomized control trial was designed to compare the effectiveness of different intra-canal medications on postoperative tooth pain, with a Control group.
