This randomized clinical trial aimed to compare postoperative pain after the use of 2different irrigation activation techniques: passive ultrasonic irrigation and the EasyClean device.
Sixty-six single-rooted teeth diagnosed with asymptomatic pulp necrosis and apical periodontitis were randomly assigned to 2experimental groups (n = 33), which differed in the irrigation activation technique. Postoperative pain levels were assessed after 24, 48, and 72 hours using a verbal rating scale; the ibuprofen intake amount was recorded at the same time intervals. Data were analyzed using Student's t-test, Mann-Whitney U and Fisher's exact tests, with a significance level of 5%.
Postoperative pain levels and analgesic intake frequency were not significantly different across the 2irrigation activation techniques (P > .05). The frequencies obtained in relation to the prevalence of postoperative pain were 3.1-25.8% for all participants of the 2studied groups.
The irrigation activation techniques of passive ultrasonic irrigation and the EasyClean device were found to be equivalent in terms of postoperative pain and analgesic intake.
本随机临床试验旨在比较使用两种不同冲洗激活技术（被动超声冲洗和 EasyClean 设备）后的术后疼痛。
将 66 颗诊断为无症状牙髓坏死和根尖周炎的单根牙随机分为 2 个实验组（n = 33），两组的冲洗激活技术不同。使用口头评分量表在 24、48 和 72 小时评估术后疼痛水平；同时记录布洛芬的摄入量。使用 Student's t 检验、Mann-Whitney U 和 Fisher 确切检验分析数据，显著性水平为 5%。
两种冲洗激活技术之间的术后疼痛水平和镇痛剂摄入频率无显著差异（P >.05）。对于两个研究组的所有参与者，与术后疼痛的患病率相关的频率为 3.1-25.8%。
被动超声冲洗和 EasyClean 设备的冲洗激活技术在术后疼痛和镇痛剂摄入方面等效。
