摘要： 目的 评价MTWO镍钛根管预备系统在磨牙根管治疗中的应用效果。方法 选取2008年1月至2009年2月解放军第463医院口腔科门诊收治的需做根管治疗的患者110例（126颗患牙），随机分成2组，试验组72颗，对照组54颗;分别采用MTWO镍钛根管预备系统和不锈钢Ｋ锉行根管预备，次氯酸钠溶液和EDTA凝胶疏通并清理根管内感染物质，采用侧向加压技术行根管充填;根据临床操作时间、术后X线片及疼痛情况评价根管预备和充填的效果。结果 试验组根管预备平均时间为4 min 10 s，明显少于对照组的10 min 50 s;试验组无根管偏移及台阶形成，能较好地保持根管的解剖初形，对照组中２例有台阶形成;试验组适充率（94.4%）明显高于对照组（81.5%）（P ＜ 0.01），术后３d 疼痛的发生率（4.2%）明显低于对照组（13.0%）（P ＜ 0.01）。结论 用MTWO镍钛根管预备系统预备根管能很好地维持根管解剖形态，减少术后疼痛，并且省时、高效，提高了根充效果。

Abstract: Objective To evaluate the MTWO Nickel-titanium instruments applied to molar root canal therapy. Methods A total of 126 teeth treated by root canal therapy from 2008 to 2009 were randomly divided into two groups， the experimental group 72， control group 54， root canal respectively prepared by MTWO nickel-titanium instrument and stainless steel K file system，infection substances dredged and cleaned by sub - sodium chlorate solution and EDTA gel， filled by lateral compression technique. The root canal preparation and filling effect were valued according to the clinical operation time， postoperative X-ray film and pain. Results The average time for MTWO root canal preparation was 4 min10 s， significantly less than the control group （10 min 50 s）; in the experimental group root canal had no deviation or the steps shaping， and could better maintain the root canal anatomy in early form; the control group had two cases of steps shaping; exact filling in the experimental group was 94.4%，significantly higher than that in the control group（ 81.5% ）（P < 0.01）; the pain of experiment group after three days was 4.2%，significantly less than that in control group（13.0% ）（P < 0.01）. Conclusion MTWO Nickel-titanium instruments in root canal preparation can result in a very good maintenance of root canal anatomy and reduce postoperative pain， and it is time-saving and efficient.
