Abstract Aim: The purpose of this study was to evaluate the effect of propolis compared to calcium hydroxide as intracanal medicaments on postoperative pain in patients with necrotic pulp during two visit treatment. Methods: In this study, fifty four participants with an age ranged from 20-50 years old with no gender predilection, diagnosed as having necrotic pulp with chronic periapical periodontitis in their single rooted single canal teeth were included in this study. Patients were randomly assigned into any of these two groups {uF02D}group A: calcium hydroxide paste (comparator). {uF02D}group B: propolis paste (intervention). Access cavity was done under rubber dam isolation. Working length was determined by apex locator and confirmed by periapical radiograph; mechanical preparation was accomplished in the same visit by ProTaper Universal rotary files system. According to the randomization table, one of tested intracanal medicaments was placed with long disposable tip, and finally the access cavity was sealed with resin-modified glass ionomer filling. Patients were instructed to rate their pain score after 24, 48, 72 hours then after 7 days at the day of the second visit. After 7 days the intracanal medicament was removed then finally root canal was obturated |
