目的:观察3%双氧水在预防下颌阻生智齿拔除术后干槽症的临床效果。方法:选择需要拔除的下颌阻生智齿350颗,随机分为2组,实验组拔牙创用3%双氧水冲洗3次,对照组拔牙创不做任何处理。结果:实验组干槽症发生率1.14%,对照组干槽症发生率6.29%。两组发生率经统计学分析有显著性差异(P<0.05)。结论:3%双氧水冲洗能有效预防下颌阻生智齿拔除术后干槽症的发生。
Objective: To observe the clinical effect of 3% hydrogen peroxide in preventing dry socket after mandibular impacted wisdom tooth extraction. Methods: 350 mandibular impacted wisdom teeth were selected and randomly divided into 2 groups. In the experimental group, tooth extraction was performed with 3% hydrogen peroxide for 3 times. In the control group, tooth extraction was done without any treatment. Results: The incidence of dry-cell syndrome was 1.14% in the experimental group and 6.29% in the control group. The incidence of the two groups was statistically significant (P <0.05). Conclusion: 3% hydrogen peroxide flushing can effectively prevent dry socket after mandibular impacted wisdom tooth extraction.
