口腔组织补片置入拔牙创预防术后并发症

Prevention of postexodontic complications by oral tissue patch embedded in socket after tooth extraction: A clinical randomized and controlled study

目的:评估口腔组织补片局部应用对阻生牙拔除术后并发症的预防作用。方法:将 200例拔除阻生牙的患者随机分成甲、乙两组。在牙拔除术后,甲组向牙槽窝中置入口腔组织补片,乙组为空白对照。术后观察两组并发症的发生率。结果:甲、乙两组干槽症的发生率分别为 1%、8%,甲组无拔牙术后出血发生,乙组为 6%。甲组与乙组间有显著性差异。结论:口腔组织补片的局部应用对阻生牙拔除术后并发症的发生有一定的预防作用。

Objective: To evaluate the prevention of postexodontic complications by oral tissue patch embedded in socket after tooth extraction. Methods:200 patients with impacted mandibular third molar were divided into two groups at random with 100 in each group. In group 1 the oral tissue patch was put into the sockets after tooth extraction. Group 2 was the blank control.Postexodontic complications of the two groups were observed after treatment. Results:Dry socket (DS) incidence rate in group 1 and 2 was 1% and 8%(P<0.05), hemorrhage incidence rate 0% and 6%(P<0.01),respectively.Conclusion:Oral tissue patch embedded in socket after tooth extraction can prevent postexodontic complication.
