Post‐operative pain after single‐visit root canal treatment using resin‐based and bioceramic sealers in teeth with apical periodontitis: A randomised controlled‐trial

Abstract The present study aimed to compare postoperative pain in teeth with symptomatic and asymptomatic apical periodontitis (AP) following a single‐visit endodontic treatment using BioRoot™ RCS or AH Plus at 8 h, 24 h and 48 h postoperatively. Postgraduate students performed endodontic treatment on 101 teeth with AP, randomised into two obturation groups. A 100‐mm Visual Analog Scale was used to document the intensity of pain at preoperative, 8‐h, 24‐h and 48‐h intervals. The Kolmogorov–Smirnov test was used for normality, and the median and interquartile ranges were compared using the Mann–Whitney U test. Preoperative pain (1.90 ± 3.50) was more frequent in teeth with symptomatic AP ( p < 0.05). However, no significant differences were observed in postoperative pain at the 8‐h, 24‐h and 48‐h intervals. Pre and postoperative pain were directly associated ( p < 0.05). Single‐visit root canal treatment in teeth with AP using both sealers resulted in similar levels of postoperative pain.
