Assessment The Propolis Effect Versus Calcium Hydroxide Effect as Intracanal Medications on Post-Operative Pain in Necrotic Teeth

Aim: to evaluate the postoperative pain of using Propolis versus Calcium hydroxide as intracanal medications on post-operative pain in necrotic teeth. Subjects and Methods: 40 patients requiring endodontic treatment for single rooted teeth were enrolled in this analysis. The selected patients were separated into two groups with 20 patients each; Group І: Propolis paste. Group II: Ca (OH)2 paste. The local anesthesia was administrated, and the working length determined by Root ZX apex locator, and then confirmed radiographically. The root canals were mechanically prepared in a crowndown approach using the “TF Adaptive” setting on Elements Motor. TF Adaptive Green ML1 file (Medium Large) and Yellow ML2 size 35 taper 4% until the file reaches wanted length. Intracanal medicaments of the two groups were placed inside the canals and left for a week. Then the obturation was done in the second visit. Postoperative pain was judged by visual analogue scale (VAS) after 24 hours, 48 hours and 72 hours. Results: The pain intensity showed that there was no statistically noteworthy difference concerning the two groups. Conclusions: Propolis is an effective and safe intracanal medication that can be used to reduce post-operative pain in necrotic teeth. INTRODUCTION Pain and related suffering are globally relevant topics for health-care providers (1), Pain of endodontic origin is widely feared by the public (2), but only 17% of subjects experiencing root canal treatment described it as their most painful dental experience (3). Root canal therapy lowers pain incidence although immediate post-treatment pain severity may sometimes exceed the pretreatment sternness levels. Current inflammatory processes or apical instrumentation especially with former peri radicular inflammation may cause this (4). Post-operative pain predominance at 24 hours was 40% and markedly decreased during the first 2 days after treatment, dropping to 10% or less after 7 days. Flare-up defined as a serious exacerbation of a pulpal or peri radicular pathosis with a subsequent development of pain
