应用微波辐射处理根管对104例(112颗患牙)急、慢性根尖周病进行治疗。并与同期98例(108颗患牙)急、慢性根尖周病用常规封药处理根管作3年以上的临床随访对照观察。结果:微波组和封药组成功率分别为96.4％、93.5％,两组疗效无显著性差异(P>0.05);每颗患牙平均复诊次数微波组与封药组分别为1.13次和2.36次。两组有非常显著性差异(P<0.01)。应用微波处理根管具有消除症状块,消毒效果确切,复诊次数少,操作简便,副作用少等特点。远期疗效也较为肯定,值得推广使用。
104 cases (112 teeth) of acute and chronic apical periodontitis were treated with microwave radiation. And with the same period 98 cases (108 teeth) acute and chronic periapical disease with conventional drug treatment of root canal for more than 3 years follow-up clinical observation. Results: The power of microwave group and sealant group were 96.4% and 93.5% respectively, there was no significant difference between the two groups (P> 0.05). The mean number of visits for each tooth was 1.13 times and 2.36 times . There was a significant difference between the two groups (P <0.01). Application of microwave root canal treatment with the elimination of symptoms, the exact effect of disinfection, referral times, easy to operate, fewer side effects. Long-term efficacy is also more positive, it is worth promoting the use of.
