摘　　要：目的:观察WaveOne机用镍钛锉和不锈钢K锉分别用于老年人残根残冠一次法根管治疗的时间以及术后疼痛反应情况,为老年人残根残冠的桩核冠修复提供临床参考。方法:选择临床就诊的115例老年患者,共187颗残冠残根,随机分成两组,WaveOne组(98颗患牙)和K锉组(99颗);两组患牙均采用一次法根管治疗术,其中WaveOne组在完成根管预备时采用WaveOne机用镍钛锉冠向下法,K锉组则使用不锈钢K锉配合传统的逐步后退法预备根管。比较两组之间选用不同器械和不同根管预备方法一次完成根管预备及充填所需的时间及患者术前及术后24h、7d的疼痛反应。结果:WaveOn组根管预备所需时间(4.36±0.19)min,较K锉组(14.63±0.38)min短;术前、术后7d两组疼痛评定差异无统计学意义(P>0.05),而术后24h两组差异有统计学意义(P<0.05)。结论:采用WaveOne机用镍钛锉对于老年人残根残冠修复前进行一次法根管预备与充填能够缩短治疗时间,提高根管预备效率及减少术后疼痛反应,有效增加患者的依从性。Objective To evaluate the preparation times and the post-operative pain level of one-visit endodontic treatment using WaveOne and K fle for residual root and crown in the elderly people. Methods A total of 187 residual roots and crowns were selected from 115 elderly patients.They were randomly divided into WaveOne group （n=98） and K fle group （n = 99）. Two groups were treated with one-time root canal therapy, The experimental group used WaveOne nickel titanium with crown-down method, and the control group using stainless steel K fles with step-back technique. A comparison of the clinical results was done between the two groups. The main assessments included before-operative, 24h and 7 days of post-operation pain evaluated by patients and dentists, meanwhile the preparation times for each time was recorded. Results The time required to prepare the canals was shorter in WaveOne group than in stainless steel K fles group （P〈0.05）. There was no statistical signifcance between the groups for before-operative and 7 days of post-operative pain of one-visit endodontic treatment（P〉0.05）, but there was signifcant difference between the two groups in postoperative 24h pain （P〈0.05）. Conclusion One-visit endodontic treatment using WaveOne for the treatment of the residual root and crown of the aged patients can shorten the treatment time, improve the effciency of root canal preparation and reduce postoperative pain.
