Single- and multiple-visit root canal treatment has been the subject of long-standing debate in the endodontic community, so the purpose of this study was to determine the incidence of postoperative flare-up after single- and multiple-visit endodontic therapy in permanent teeth.
A total of 65 children aged >10 years who underwent root canal treatment were randomly categorized equally into two treatment groups: the first group underwent single-visit treatment, and the other group underwent multiple-visit therapy. The visual analog scale was employed to evaluate pain preoperatively and postoperatively after obturation. Recall visits were carried out after 1 week, 1 and 3, 6 and 9 months. The Statistical Package for the Social Sciences version 15.0 was employed for statistical analysis.
Except at the baseline, at all the other time intervals, the mean pain score in the multiple-visit group was higher as compared to that of the single-visit group; statistically no significant difference was found.
The mean pain score in the single-visit group was lower as compared to that of the multiple-visit group; however, the difference between the two groups was statistically significant (P > 0.05).
单次就诊和多次就诊根管治疗一直是牙髓病学界长期争论的话题，因此本研究的目的是确定恒牙单次就诊和多次就诊牙髓治疗术后疼痛发作的发生率。
共有65名年龄大于10岁接受根管治疗的儿童被随机等分为两个治疗组：第一组接受单次就诊治疗，另一组接受多次就诊治疗。采用视觉模拟量表评估充填术前和术后的疼痛情况。在1周、1、3、6和9个月后进行回访。使用社会科学统计软件包第15.0版进行统计分析。
除基线外，在所有其他时间间隔，多次就诊组的平均疼痛评分均高于单次就诊组；但统计学上未发现显著差异。
单次就诊组的平均疼痛评分低于多次就诊组；然而，两组之间的差异具有统计学意义（P>0.05）。
