BACKGROUND
This clinical study aims to compare postoperative pain after single-visit root canal treatment of teeth with asymptomatic apical periodontitis using epoxy-resin-based AH Plus and calcium silicate-based Endosequence BC sealers with or without sonic activation.
METHODS
This study included 72 individuals with one first or second mandibular premolar tooth with asymptomatic apical periodontitis. They were randomly divided into four groups according to the root canal sealer (AH Plus or Endosequence BC) and activation protocol (sonic activation or non-activation) (n = 18). The participants were ask to rate their postoperative pain intensity on a NRS scale as none, minimal, moderate, or severe after 24 h, 48 h, 72 h, and 7 days following treatment. Patients were also asked to record the number of prescribed analgesic medication tablets (400 mg of ibuprofen) taken. Statistical analysis were performed using the Mann-Whitney U test, the Friedman test, the Spearman's correlation test, the Chi-square test. Significance level was established at 0.05.
RESULTS
There was no statistically significant difference in postoperative pain scores or analgesic intake between AH Plus and Endosequence BC sealers regardless of the activation protocol (p > 0.05). There was no statistically significant difference in postoperative pain scores between the sonic activation and non-activation groups (p > 0.05). A weak positive correlation was detected between Endoactivator sonic activation and sealer extrusion (r = 0.36).
CONCLUSIONS
AH Plus and EndoSequence BC root canal sealers showed similar results in terms of prevalance and intensity of postoperative pain. Sonic activation and non-activation groups had similar postoperative pain scores.

背景
本临床研究旨在比较单次就诊根管治疗伴有无症状根尖周炎的牙齿术后疼痛，使用基于环氧树脂的 AH Plus 和基于硅酸钙的 Endosequence BC 封闭剂，是否联合超声激活。
方法
本研究纳入了 72 名患有无症状根尖周炎的第一或第二下颌前磨牙的个体。他们根据根管封闭剂（AH Plus 或 Endosequence BC）和激活方案（超声激活或非激活）（n = 18）随机分为四组。在治疗后 24、48、72 小时和 7 天，参与者使用 NRS 量表评估他们的术后疼痛强度，分为无、轻度、中度或重度。患者还记录服用的处方止痛药物片数（400 毫克布洛芬）。使用 Mann-Whitney U 检验、Friedman 检验、Spearman 相关检验、卡方检验进行统计分析。显著性水平设定为 0.05。
结果
无论激活方案如何，AH Plus 和 Endosequence BC 封闭剂的术后疼痛评分或镇痛药摄入均无统计学差异（p > 0.05）。超声激活组和非激活组的术后疼痛评分无统计学差异（p > 0.05）。Endoactivator 超声激活与封闭剂挤出之间检测到弱正相关（r = 0.36）。
结论
AH Plus 和 EndoSequence BC 根管封闭剂在术后疼痛的发生率和强度方面表现出相似的结果。超声激活组和非激活组的术后疼痛评分相似。
临床试验注册
