| 摘 要： | 目的： 比较不同根管预备方法对根管治疗诊间急症(interappointment emergencies,IAE)发生率和根管充填效果的影响。方法： 2018年8月—2021年8月因牙髓炎或根尖周炎需要做根管治疗的恒磨牙96颗,随机分为2组（n=48）颗,MT组使用 Mtwo机用镍钛锉改良 Mtwo根管预备法,同步组使用改良 Mtwo预备技术加同步根管长度测量根管预备法。根管预备完成后拍摄根尖片,根管内封入氢氧化钙,复诊时行常规热牙胶根管充填。采用 SPSS 22.0 软件包分析IAE的发生情况及术后充填效果。结果： 术后即刻及术后第3 天、1周,2组IAE发生率无显著差异（P>0.05）;术后第1、2 天,同步组IAE发生率显著低于MT组（P<0.05）,同步组根管充填的合格率显著高于MT组（P<0.05）。结论： 同步法能减少根管预备过程中根尖区的机械刺激,严格控制根管的工作长度,维持根尖区屏障,从而降低IAE发生率并有效提高根管充填合格率。

| Abstract: | PURPOSE: To compare the effect of different root canal preparation methods on the incidence of interappointment emergencies (IAE) and root canal filling. METHODS: A total of 96 teeth requiring root canal therapy due to pulpitis or periapical periodontitis from August 2018 to August 2021 were selected. They were randomly divided into 2 groups: MT group was treated with Mtwo root canal preparation method modified by Mtwo machine nickel-titanium file, while synchronous group was treated with modified Mtwo preparation method and synchronous root canal length measurement. After root canal preparation, the trial point film was taken, calcium hydroxide was used to seal the root canal, and routine thermoplasticizied gutta-percha root canal filling was performed during the follow-up visit. SPSS 22.0 software package was used to analyze the incidence of IAE and filling effect after root canal therapy. RESULTS: There was no significant difference in the incidence of IAE between the two groups immediately after operation, three days and 1 week after operation(P>0.05); the incidence of IAE in synchronous group was significantly lower than that in MT group at 1 and 2 days after operation(P<0.05). The qualified rate of root canal filling in synchronous group was significantly higher than that in MT group (P<0.05). CONCLUSIONS: Synchronous method can reduce mechanical stimulation of apical area during root canal preparation, strictly control the working length of root canal and maintain apical barrier, thus reducing the incidence of IAE and effectively improving the qualification rate of root canal filling. |
