摘要
目的:观察和对比老年人与青年人两个不同年龄组活髓牙一次性根管治疗术的术后急性炎症反应及远期疗效。方法:实验组343例589颗活髓患牙,对照组616例1249颗活髓患牙,均采用一次性根管治疗术,观察和对比术后临床反应及远期疗效。结果:术后2天内出现根管治疗术术后急发症的比例分别为,实验组为0级:48.7%,1级:45.7%,2级:5.3%,3级:0.34%;对照组为0级:46.8%,1级:48.8%,2级:4.4%,3级:未发生。通过术后2年的观察,其回访率达80%以上,实验组和对照组根管治疗的成功率分别为94.4%和96.2%。结论:老年人与青年人活髓牙一次性根管治疗术的术后反应概率及远期疗效对比无明显差别。
Objective：To observe and compare the acute inflammation and long-term efficacy between the young and elderly vital teeth after one-visit root canal therapy.Methods：Experimental group：549 vital teeth from 343 elderly cases.Control group：1249 vital teeth from 616 young cases.Adopt one-visit root canal therapy to all cases.Results：the proportion of acute inflammation during from 12 hours to several days as follows,in experimental group：48.7% for zero grade,45.7% for one grade,5.3% for second grade and 0.34% for third group;meanwhile,in the control group,46.8% for zero grade,48.8% for first grade,4.4% for second grade and 0% for third group.By observing the subsequent two years,the cure rates were 94.4% and 96.2% in experimental and control group respectively.Conclusion：There are no significant differences in postoperative reflection and long-term efficacy between the elderly and young vital teeth after one-visit therapy.
