中文摘要
      目的：探讨不同根管冲洗技术对不可复性牙髓炎根管治疗术后疼痛影响的临床研究。方法：选择126例成人有症状的不可复性牙髓炎的下颌磨牙病例,根管预备完成后,按不同的终末冲洗方法随机分成3组：注射器冲洗组、超声冲洗组和手动活化冲洗组,每组各42例。采用热牙胶充填法一次性完成根管充填。记录3组患者术后疼痛VAS分值,比较3组患者术后疼痛发生率及VAS分值的统计学差异。结果：术后6h和24h,三组相比,手动活化冲洗组中VAS分值显著较高,有统计学差异(P<0.05),其它时间段VAS分值降低,无统计学意义(P>0.05)。结论：对于有症状的不可复性牙髓炎的下颌磨牙中,术后24h,手动活化冲洗组引起会引起较高的术后疼痛。
英文摘要
      Objective: To evaluate different irrigation technique on postoperative pain in mandibular molar teeth with symptomative irreversible pulpitis. Method:126 patients with a single tooth diagnosed as symptomatic irreversible pulpitis were selected. Teeth were randomly assigned to 4 groups based on the final irrigation methods. In group 1 (needle irrigation), irrigation was conducted without agitation with a side-port needle; in group 2, passive ultrasonic irrigation was used; and in group 3, MDA was used. Teeth were then obturated with gutta-percha and a resin-based sealer using the cold lateral compaction technique. The presence of postoperative pain was assessed after 6, 24, 48, and 72 hours and 1 week. Results: At the 6- and 24-hour time intervals, group 3 patients reported more intense postoperative pain than those patients in groups 1, 2, and 3 (P <0.05). There was no significant difference among the groups at the other time intervals (P > 0.05), and in all groups the intensity of postoperative pain decreased over time. Conclusions: MDA caused greater postoperative pain after endodontic therapy in mandibular molar teeth with symptomatic irreversible pulpitis compared with the other methods in the first 24 hours.
