目的探讨感染根管一次性根管治疗的短期临床治疗效果,为一次性根管治疗提供参考。方法选择诊断为牙髓坏死、急慢性牙髓炎或根尖周炎的患者108例(120颗患牙),随机分成2组,一次治疗组采用一次性根管治疗,多次治疗组采用传统根管治疗。总结分析2组术后疼痛情况以及短期临床效果。结果一次治疗组患者术后13牙出现疼痛,多次治疗组患者术后14牙出现疼痛,2组患者疼痛牙数差异无统计学意义(P>0.05);手术后半年,一次法治疗组治疗总有效率为95.16%,多次法治疗组治疗总有效率为93.10%。2组治疗总有效率差异无统计学意义(P>0.05)。结论感染根管一次性根管治疗和传统多次根管治疗术后疼痛以及短期临床治疗效果差异无统计学意义,在临床治疗上具有可行性。
Objective To investigate the short-term clinical effect of one-time root canal therapy of infected root canal and provide a reference for one-time root canal therapy. Methods A total of 108 patients (120 teeth) diagnosed as dental pulp necrosis, acute or chronic pulpitis or periapical periodontitis were randomly divided into two groups. The primary treatment group received one-time root canal therapy and the multi-treatment group adopted the traditional Root canal treatment. To summarize and analyze the postoperative pain and short-term clinical results in two groups. Results In the first treatment group, 13 teeth showed pain after operation, 14 teeth showed pain in multiple treatment groups, and there was no significant difference in the number of pain teeth between the two groups (P> 0.05). Six months after operation, The total effective rate was 95.16%. The total effective rate of multiple treatment group was 93.10%. There was no significant difference in the total effective rate between the two groups (P> 0.05). Conclusion There is no significant difference in the postoperative pain and the short-term clinical effect between the two groups of patients after one-time root canal treatment of infected root canal and conventional multi-root canal treatment, which is feasible in clinical treatment.
