Postoperative pain is a common concern in root canal treatment, and the choice of instrumentation technique can significantly impact patient comfort. This study aimed to evaluate the impact of different instrumentation techniques on the incidence of postoperative pain in patients undergoing root canal treatment.
A randomized controlled trial was conducted on 208 patients randomly assigned to four groups: step-back preparation, crown-down preparation, hybrid technique, and conventional instrumentation. Pain intensity was assessed using a verbal rating scale (VRS) at six, 12, 24, 48, and 72 hours postoperatively. Data were analyzed using appropriate statistical methods.
The mean pain scores and standard deviations (SDs) were calculated for each instrumentation technique at different time intervals. At six hours, the step-back preparation group reported a mean pain score of 2.3 (SD = 0.8), the crown-down preparation group had a score of 2.8 (SD = 0.9), the hybrid technique group had a score of 2.5 (SD = 0.7), and the conventional instrumentation group had a score of 3.1 (SD = 0.1). The differences in pain scores between the groups were statistically significant at all time intervals (p < 0.05).
The choice of instrumentation technique significantly influenced the incidence of postoperative pain in root canal treatment. The step-back preparation technique was associated with lower pain intensity than the crown-down preparation, hybrid technique, and conventional instrumentation. These findings highlight the importance of considering the instrumentation technique to optimize patient comfort during and after root canal treatment.
术后疼痛是根管治疗中常见的问题，器械预备技术的选择会显著影响患者的舒适度。本研究旨在评估不同器械预备技术对接受根管治疗患者术后疼痛发生率的影响。
对208例患者进行随机对照试验，随机分为四组：逐步后退法预备、冠向下法预备、混合技术和传统器械预备。术后6、12、24、48和72小时使用视觉模拟评分法（VRS）评估疼痛强度。采用适当的统计方法对数据进行分析。
计算了不同时间间隔下每种器械预备技术的平均疼痛评分和标准差（SD）。6小时时，逐步后退法预备组的平均疼痛评分为2.3（SD = 0.8），冠向下法预备组评分为2.8（SD = 0.9），混合技术组评分为2.5（SD = 0.7），传统器械预备组评分为3.1（SD = 0.1）。各时间间隔组间疼痛评分差异均有统计学意义（p < 0.05）。
器械预备技术的选择对根管治疗术后疼痛的发生率有显著影响。逐步后退法预备技术与冠向下法预备、混合技术和传统器械预备相比，疼痛强度更低。这些发现凸显了在根管治疗期间及之后考虑器械预备技术以优化患者舒适度的重要性。
