1432例根管治疗的临床疗效分析

Clinical Analysis of 1432 Cases of Root Canal Therapy

目的:评价根管治疗术(RCT)治疗前患牙情况和根管充填情况对疗效的影响。方法:随机抽取完成RCT的1 432个患牙为研究对象,分析RCT的治疗质量、2年后临床疗效、治疗前患牙情况和根管充填情况对疗效的影响。结果:1 432个患牙,RCT的恰填率为69.34%,欠填率为12.01%,超填率为16.06%;漏填率为2.58%,磨牙前磨牙根管全治率(无遗漏根管)96.52%。患牙2年回访725个,回访率50.63%。2年临床成功687个牙,成功率94.76%。恰填、欠填、超填、漏填的成功率分别为98.72%、78.57%、87.80%、78.57%;牙髓病和根尖周病的成功率分别为恰填98.79%、98.65%,欠填91.18%、70.00%,超填90.32%、86.27%,漏填80.00%、77.78%。结论:前牙根管充填质量最好;2年后恰填成功率最高;当充填有缺陷时,相同缺陷情况下根尖周病组成功率明显低于牙髓炎病组,尤其欠填和漏填对有根尖周病的成功率影响更大。

AIM： To evaluate the clinical effect of root canal therapy （RCT） and root canal obturation in comparison to before treatment. METHODS ： 1432 teeth treated during Jan 2004 to Jan 2006 were randomly selected to evaluate the effect of root canal treatment, clinical efficacy after 2 years, in comparison to before treatment in Dental Hospital of Guangzhou Medical College. RESULTS： The percentage of adequate filling, under filling, over filling , and omitting filling are 69.34% , 12.01% , 16.06% and 2.58% respectively. The cure rate of RCT of molar and premolar is 96.52%. 725 teeth were observed again after 2 years with proportion of 94.76%. 2 -years clinical successive rate of treatment is 687 teeth is 94.76%. The successive rate of adequate filling, under filling, over filling , omitting filling are 98.72% ,78.57% ,87.80% and 78.57% independently. The recovery rate of pulp disease and periapecitis are 96.85% and 93.12% seperately. CONCLUSION： The root canal filling of anterior teeth has high quality and the success rate of adequate - filling group is higher than others . When obturation is not perfect, the group of periapecitis has a lower healing rate than pulp disease group. Especially both of under - filling and omitting - filling produce an relatively huge effect on the success of root canal treatment.
