This study aimed to evaluate the effect of multi-file rotary (Protaper Universal) and reciprocating single-file (Reciproc Blue) root canal preparation techniques on the occurrence of postoperative pain in asymptomatic mandibular molar teeth with large periapical lesions in single-visit root canal treatment (RCT). A hundred and twenty teeth were randomly assigned to two groups: Protaper Universal (PTU) or Reciproc Blue (RB) instruments. Postoperative pain at 6, 12, 24, 48, 72 h and 7 days after obturation was measured. Mann-Whitney U-test was performed to compare the pain scores between the groups and to assess the relation of pain with patients' age and gender. Spearman's rank correlation was utilized to correlate the pain intensity and analgesic intake at different time points. There was no significant difference between the instrumentation techniques regarding postoperative pain at any time points evaluated (P > 0.05). There was a correlation between analgesic intake and intensity of pain (P < 0.05). No statistically significant difference was found among the groups assessed in the study in terms of analgesic intake (P > 0.05).
本研究旨在评估在单次就诊根管治疗（RCT）中，多根旋转器械（Protaper Universal）和往复单根器械（Reciproc Blue）对患有较大根尖周病变的无症状下颌磨牙术后疼痛发生率的影响。120颗牙齿被随机分为两组：Protaper Universal（PTU）组或Reciproc Blue（RB）组。测量了充填后6、12、24、48、72小时和7天的术后疼痛情况。采用曼-惠特尼U检验比较两组间的疼痛评分，并评估疼痛与患者年龄和性别的关系。使用Spearman等级相关性分析不同时间点的疼痛强度和镇痛药物摄入量之间的相关性。在评估的任何时间点，两种器械预备技术在术后疼痛方面均无显著差异（P>0.05）。镇痛药物摄入量与疼痛强度之间存在相关性（P<0.05）。在研究评估的各组间，镇痛药物摄入量方面未发现统计学显著差异（P>0.05）。
