摘要： 目的: 探讨在下颌阻生第三磨牙拔除术中使用不同温度生理盐水冲洗对术后并发症的影响。方法: 选取2021年2月—2025年6月于合肥市口腔医院拔除双侧下颌阻生第三磨牙的患者21例,采用随机自身对照设计,将双侧阻生牙分为试验组（术中使用4 ℃低温生理盐水冲洗）与对照组（术中使用26 ℃室温生理盐水冲洗）。所有患者分次拔除双侧阻生牙,两次手术互为对照。采用视觉模拟评分法（visual analog scale,VAS）记录术后 0.5、2、6、12、24、72 h的疼痛评分,同时记录手术时间、术后72 h水肿程度、止痛药用量、开口度、术后出血情况及干槽症发生率。结果: 试验组手术后2 h和6 h的VAS评分及72 h水肿程度显著低于对照组（P<0.05）;手术时间、止疼药用量、开口度、术后出血情况、是否出现干槽症以及其他记录时间点VAS评分,两组间均无显著差异（P>0.05）。结论: 下颌阻生第三磨牙微创拔除术中使用4 ℃低温生理盐水冲洗,可显著减轻术后2 h和6 h的疼痛及72 h的水肿程度,值得临床推广应用。

Abstract: PURPOSE: To investigate the effect of normal saline irrigation at different temperatures on postoperative complications during the extraction of impacted mandibular third molars. METHODS: A total of 21 patients who underwent extraction of bilateral impacted mandibular third molars at Hefei Stomatological Hospital from February 2021 to June 2025 were enrolled in this study. A randomized self-controlled design was adopted, where the bilateral impacted teeth were divided into an experimental group (irrigated with 4 ℃ low-temperature normal saline during surgery) and a control group (irrigated with 26 ℃ room-temperature normal saline during surgery). All patients received staged extraction of bilateral impacted teeth, with the two surgeries serving as mutual controls. The visual analog scale (VAS) was used to record the pain scores at 0.5, 2, 6, 12, 24 and 72 hours postoperatively. Meanwhile, the operation time, the degree of edema at 72 hours postoperatively, the dosage of analgesics, mouth opening degree, postoperative bleeding, and the incidence of dry socket were recorded. RESULTS: The VAS scores at 2 and 6 hours postoperatively and the degree of edema at 72 hours postoperatively in the experimental group were significantly lower than those in the control group (P<0.05). No significant differences were found between the two groups in operation time, analgesic dosage, mouth opening degree, postoperative bleeding, the incidence of dry socket or VAS scores at other recorded time points (P>0.05). CONCLUSIONS: Irrigation with 4 ℃ low-temperature normal saline during minimally invasive extraction of impacted mandibular third molars can significantly alleviate postoperative pain at 2 and 6 hours and edema at 72 hours, which is worthy of clinical application.
