One of the most common complications of root canal treatment is postoperative pain. The aim of the present clinical trial was to compare the severity of postoperative pain after root canal preparation with RaCe rotary system and hand K-Flexofile.
A total of 96 mandibular first and second molars were divided into two groups (=48) based on root canal preparation technique. The teeth in both groups underwent one-session root canal treatment and the severity of postoperative pain was evaluated using visual analog scale (VAS) at 4-, 8-, 12-, 24- and 48-h and 1-week intervals. In addition, the type and dosage of analgesics were recorded. Data were analyzed with repeated-measures ANOVA. Statistical significance was set at 0.05.
The difference between the two groups during this period and at subsequent intervals were not significant (>0.05). There were no significant differences between the two groups in type and the number of analgesics in pain-free subjects (=0.12 and =0.61, respectively).
There were no statistically significant differences in pain severity between the two groups at any intervals.
根管治疗最常见的并发症之一是术后疼痛。本临床试验的目的是比较使用RaCe旋转系统和手动K-Flex锉进行根管预备后术后疼痛的严重程度。
根据根管预备技术，将96颗下颌第一和第二磨牙共分为两组（每组 = 48颗）。两组牙齿均接受一次性根管治疗，并在4小时、8小时、12小时、24小时、48小时和1周间隔时使用视觉模拟量表（VAS）评估术后疼痛的严重程度。此外，记录镇痛药的类型和剂量。数据采用重复测量方差分析进行分析。统计学显著性设定为0.05。
在此期间及随后各时间间隔，两组之间的差异均无统计学意义（>0.05）。无痛受试者中，两组在镇痛药类型和数量方面均无显著差异（分别为 = 0.12和 = 0.61）。
在任何时间间隔，两组之间的疼痛严重程度均无统计学显著差异。
