      【摘要】 目的 研究改良根管治疗对牙髓病或根尖周病患者根管预备和充填质量的影响。方法 选取2018年7月至2019年6月在西安大兴医院口腔科门诊治疗的100例牙髓病或根尖周病患者进行研究，按照随机数表法分为对照组和观察组，各50例。对照组采用常规根管预备和充填方法进行根管治疗，观察组采用改良根管预备和充填方法进行根管治疗，治疗后，评价两组患者的根管预备和充填效果，以及术后疼痛和近期及远期的临床治疗效果。结果 观察组患者根管治疗后的合格率为96.0%，明显高于对照组的84.0%，差异有统计学意义(P<0.05)；观察组患者根管治疗后 3、6、12个月的治疗有效率分别为 98.0%、96.0%、92.0%，明显高于对照组的 86.0%、82.0%、72.00%，差异均有统计学意义(P<0.05)；观察组患者根管治疗后充填位置合格率为 86.0%，明显高于对照组的66.0%，差异有统计学意义(P<0.05)；观察组患者术后疼痛发生率34.0%，明显低于对照组的60.0%，差异有统计学意义(P<0.05)。结论 改良根管治疗能明显改善牙髓病或根尖周病患者根管预备和充填质量，提高患者根管治疗有效率，值得临床推广。

【Abstract】 Objective To study the effect of modified root canal therapy on the quality of root canal prepara-tion and filling in patients with endodontic disease or periapical disease. Methods A total of 100 patients with endodon-tic disease or periapical disease, who treated in the Outpatient Department of Stomatology, Xi'an Daxing Hospital fromJune 2017 to June 2018, were selected and divided into the control group and observation group according to randomnumber table method, with 50 patients in each group. The control group was treated with conventional root canal prepara-tion and filling method, and the observation group was treated with improved root canal preparation and filling method.After treatment, the effects of root canal preparation, filling, postoperative pain, and short-term and long-term clinicaltreatment effects of the two groups were evaluated. Results After root canal treatment, the qualified rate of the observa-tion group was 96.0%, which was significantly higher than 84.0% of the control group (P<0.05); the effective rates ofthe observation group were 98.0% , 96.0% , and 92.0% respectively at 3, 6 and 12 months after root canal treatment,which were significantly higher than corresponding 86.0%, 82.0%, and 72.00% of the control group (all P<0.05); thequalified rate of filling position after root canal treatment was 86.0%, which was significantly higher than 66.0% of thecontrol group (P<0.05); the incidence of postoperative pain in the observation group was 34.0%, which was significantlylower than 60.0% in the control group (P<0.05). Conclusion Improved root canal therapy can significantly improvethe quality of root canal preparation and filling in patients with endodontic disease or periapical disease, and improve theefficiency of root canal treatment, which is worthy of clinical promotion.
