替硝唑—碘仿明胶海绵预防干槽症的临床研究

目的 评价替硝唑-碘仿明胶海绵置入下颌阻生智齿拔牙创预防术后干槽症(DS)的效果.方法 选择210例拔除阻生牙患者,术后随机分为两组,每组105例.实验组向牙槽窝中置入替硝唑-碘仿明胶海绵.对照组为空白对照.观察两组术后干槽症的发生率.结果 实验组和对照组干槽症的发生率分别为0.96%和6.67%.两组间有显著性差异(P＜0.05).结论 替硝唑-碘仿明胶海绵置入拔牙创能有效预防下颌阻生智齿拔除术后干槽症的发生.

A Clinical Study about the Prevention of Postexodontic Dry Socket by the Tinidazole-Iodoform Gelatin Sponge

Objective To evaluate clinical effects about the prevention of postexodontic dry socket (DS) by the tinidazole-iodoform gelatin sponge embedded in socket after impacted mandibular third molar extraction. Methods 21Opatients with impacted mandibular third molar were divided into two groups at random with 105 in each group. In test group tinidazole-iodoform sponge was put into the socket after impacted mandibular third molar extraction Control group was the blank control. Postexodontic dry socket of the two groups were observed after treatment. Results Dry socket (DS) incidence rate in test group and control group was 0.96% and 6.67%. There was statistically different between the test group and the control group (P<0.05). Conclusions The result demonstrated that tinidazole-iodoform gelatin sponge embedded in socket after tooth extraction could prevent efficientyly the occurrence of DS.
