摘　　要：目的比较两种根管预备方法对根管约诊间痛的影响。方法将134例急、慢性牙髓炎或根尖周炎的152颗前磨牙采用随机原则分为观察组（T组，TiLos锉混合根管预备系统）和对照组（K组，不锈钢K锉），T组使用逐步深入法，K组使用逐步后退法预备根管，观察并记录两组根管约诊间痛的发生率。结果T组、K组根管约诊间痛的发生率分别为6．17％、21．11％，两组差异有统计学意义（x2=7．404，P=0．007）。结论使用TiLos锉混合根管预备系统采用逐步深入法预备根管可以减少根管约诊间痛的发生。Objective To study the clinical effects of different methods on endodontic inter appointment pain （EIAP） happened to the patients after premolar root canal preparations. Methods 152 teeth from 134 patients with acute or chronic pulpitis or apical periodontitis were randomly divided into T group and K group, used TiLos mixed root canal preparation system with step - down technique and stainless steel K file with step - back technique respectively to prepare root canal. Afterwards, the incidence rates of EIAP were observed and recorded. Results The incidence rates of EIAP in T group and K group were 6. 17% and 21. 11%, respectively. There was statistically significant difference between the two groups （ x2 = 7. 404,P 〈 0.01 ）. Conclusion TiLos mixed root canal preparation system with step - down technique to prepare root cancal can reduce the incidence rate of EIAP.
