[摘要] 目的 觀察机用镍钛器械配合超声荡洗在根管治疗中的效果。方法 借助随机数字方法，从该院牙科门诊2016年6月—2017年6月接受并行根管治疗的患者中随机抽取100例展开详细的分组研究，即常规组与观察组，每组50例，首先两组均采取机用镍钛器械Protaper预备根管进行一次性填充治疗。冲洗时常规组采用传统的注射器冲洗，观察组采取超声荡洗，罗列观察、比较结果。 结果 观察组患者治疗的成功率与常规组治疗的成功分别是98.0%、92.0%，两者比较差异无统计学意义（P>0.05）；常规组术后临床反应的发生率是52.0%，观察组术后临床反应的发生率是20.0%，两者对比差异有统计学意义（P<0.05）；观察组与常规组的2级疼痛情况比较差异无统计学意义（P>0.05），但是观察组1级疼痛（80.0%）与3级疼痛（4.0%）、4级疼痛分级比例（0.0%）均优于常规组（40.0%、20.0%、10.0%）差异有统计学意义（P<0.05）。结论 在根管治疗中采取机用镍钛器械配合超声荡洗，效果显著，可缓解患者术后疼痛感，同时降低临床反应的严重程度，该方法治疗进一步推广使用。

[Abstract] Objective This paper tries to observe the effect of machine nickel-titanium instrument combined with ultrasonic wash in root canal therapy. Methods From randomized digital table method， 100 patients who underwent root canal therapy from June 2016 to June 2017 in this hospital were random selected to carry out a detailed grouping study， namely， the conventional group and the observation group， with 50 in each group. Firstly， the two groups were taken a one-time filling treatment with protaper prepared root canal machine. Conventional rinsing was performed with a conventional syringe while the observation group was ultrasonically rinsed， and the treatment effect was compared between the two groups. Results The success rate of routine treatment was 92.0%， which was not statistically significant compared with 98.0% in observation group （P>0.05）. The incidence of postoperative clinical response was 52.0% in the conventional group， which was significantly different from 20.0% in the observation group the difference was statistically significant（P<0.05）， and the difference was statistically significant. There was no statistically significant difference between the two groups in the grade 2 pain scores， but the proportion of grade 1 pain （80.0%）， grade 3 pain （4.0%） and grade 4 pain （0.0%） in the observation group were superior to those of the conventional group （40.0%，20.0%， 10.0%），the difference was statistically significant（P<0.05）. Conclusion The mechanical nickel-titanium instruments used in root canal therapy combined with ultrasonic washing， the effect is significant， can relieve pain in patients with postoperative， while reducing the severity of clinical reactions， the method of treatment to further promote and .recommand

根尖周炎作为口腔临床的常见病与多发病，具有很高的临床患病率，主要是因为患者根尖出现了长时间的持续性感染，或者受到病原刺激后导致周围组织发生炎性反应。发病之后，患者的牙槽骨遭受破坏且形成炎性肉芽组织，大大降低了患者的口腔功能，同时也对其日常生活质量造成严重影响。对于该类口腔疾病的治疗，临床上常常以根管治療为主，其中根管预备就是最为关键的一个流程，首先需要进行根管清理，再进行根管成形操作[1-2]。在此过程中，机用镍钛器械根管预备已经得到临床的广泛推广，将其与超声荡洗联合使用效果更佳。随……
