摘要： 目的 评价联合应用声波根管器械与机用Mtwo镍钛锉对磨牙进行根管预备的临床疗效。方法 选取符合纳入标准的患者100例（第一磨牙118颗,共428个根管）,按就诊顺序抽签随机分为2组,每组各50例。试验组联合应用声波根管器械与机用Mtwo镍钛锉进行根管预备,对照组采用传统不锈钢根管锉进行根管预备,2组均采用冷侧压法充填根管,观察2组根管预备时间、预备术后急症反应、根管充填质量及根充后1 a复查的治疗成功率。采用SPSS 11.0软件包进行统计学分析。结果 试验组根管预备时间平均为（5.3±0.6）min/根,对照组平均为（12.7±0.9）min/根,差异显著（t=100.89,P<0.001）;试验组根管预备术后急症反应发生率为8.20%,显著低于对照组的22.81%,差异显著（χ2=4.87,P<0.05）;试验组根管恰填率为92.86%,对照组为78.92%,差异显著（χ2=17.45,P<0.05）;根管充填后1 a的治疗成功率试验组为91.80%,对照组为78.95%,2组间差异显著（χ2=3.95,P<0.05）。结论 联合应用声波根管器械与机用Mtwo镍钛锉预备根管比传统不锈钢根管锉省时,术后疼痛反应减少,根充效果及治疗成功率提高。

Abstract: PURPOSE: To evaluate the clinical outcome of sonic endo-instruments in combination with Mtwo Ni-Ti files in root canal preparation of molars. METHODS: One hundred patients (118 first molars, 428 root canals) were included in this study, they were randomly assigned into 2 groups (n=50).Group 1 was shaped with sonic endo-instruments in combination with Mtwo Ni-Ti files,while group 2 was treated with stainless-steel files, both groups were obturated with lateral condensation technique. The time of root canal shaping, acute post-operative pain, the quality of the root canal filling and the success rate after 1 year were recorded and analyzed using SPSS 11.0 software package. RESULTS: The average preparation time in group 1 was (5.3±0.6)min/canal and (12.7±0.9) min/canal in group 2 (t=100.89,P<0.001). The rate of acute postoperative pain was significantly lower （χ2=4.87, P<0.05）in group 1 (8.20%) than in group 2 (22.81%); in group 1, 92.86% root canals were filled adequately while only 78.92% in group 2, the difference was significant (χ2=17.45, P<0.05);higher success rate (χ2=3.95, P<0.05) after 1 year was achieved in group 1 (91.80%) compared with group 2 (78.95%). CONCLUSIONS: Compared with stainless-steel files, sonic endo instruments in combination with Mtwo Ni-Ti files in root canal preparation of molars seem more effective, cause less postoperative pain and offer higher success rates.
