目的比较甲硝唑棒和胶质银在拔牙术后预防干槽症的效果。方法选择行双侧萌出状况基本相同的下颌阻生齿拔除术后598例的患者,左侧拔牙窝内放置明胶海绵及甲硝唑棒,右侧拔牙窝内放置Gelatamp胶质银止血明胶海绵,对比两侧干槽症的发生率。结果明胶海绵+甲硝唑棒组干槽症发病机率为1.5%,Gelatamp胶质银止血明胶海绵组干槽症发病率为0.3%。结论两种材料预防干槽症的效果差别不大,但其适用范围不同,各有利弊。
Objective To compare the effect of metronidazole rods and colloidal silver in preventing dry mouth syndrome after tooth extraction. Methods 598 cases of mandibular impacted teeth with identical eruption status were selected. Gelatin sponge and metronidazole rods were placed in the left socket and Gelatamp gelatin silver hemostatic gelatin sponge in the right socket. Compare the incidence of dry socket on both sides. Results The gelatin sponge + metronidazole rod group had a dry socket incidence rate of 1.5% and the Gelatamp glial silver hemostatic gelatin sponge group had a dry mouth rate of 0.3%. Conclusions The effect of two kinds of materials on prevention of dry trough is not very different, but its application scope is different, each has its advantages and disadvantages.
