摘要： 目的：观察下颌第三磨牙拔除术后不同创面处理方法对预后的影响。方法：选取临床就诊的299例骨埋伏下颌第三磨牙患者，用随机余数法将其分成3组。组1（103例）：创面拉拢缝合+口服镇痛药物+口服抗生素；组2（96例）：胶原蛋白海绵填塞+创面拉拢缝合+口服镇痛药物+口服抗生素；组3（100例）：胶原蛋白海绵填塞+碘仿粉末填塞+创面拉拢缝合+口服镇痛药物+口服抗生素。比较3组术后出血、术后肿痛及术后干槽症的发生率。结果：组3术后出血、术后肿痛及术后干槽症的发生率明显降低，预后优于组1和组2（P<0.01）。结论：组3创面处理方法更加安全可靠，值得临床进一步推广和应用。

Abstract: Objective: To evaluate the effection of different socket management methods after extraction of the impacted mandibular third molars. Methods: In total 299 patients with bone impacted mandibular third molars, were randomly assigned into 3 groups. Group 1: extraction sockets were directly sutured together, followed with oral administration of analgesia and anti-inflammatory medicine. Group 2: extraction sockets were filled with collagen sponge, and sutured, followed with oral administration of analgesia and anti-inflammatory medicine. Group 3: extraction sockets were filled with collagen sponge and iodoform powder, then sutured, followed with oral administration of analgesia and anti-inflammatory medicine. The incidence of postoperative bleeding, swelling and pain, as well as dry socket were evaluated. Results: The incidence of postoperative bleeding, swelling and pain, and dry socket were all lower in group 3 with better prognosis than the other two groups (P<0.01). Conclusion: The socket management method applied in group 3 has safe and effective outcome after extraction of the impacted mandibular third molars. This method has potential clinical value.
