目的:探究活髓牙失活后根管治疗与拔髓后根管治疗的临床疗效。方法:择取我院2013年5月-2014年10月收治的206例急性牙髓炎患者,依照信封随机分组方案分为每组均占据103例的常规组与实验组,其中常规组患者采取拔髓后根管治疗方案,实验组患者采取失活后根管治疗方案,对比两组患者的疼痛发生率与远期疗效。结果:实验组与常规组的疼痛发生率分别为1.94%与7.77%,P<0.05;实验组与常规组的远期疗效无明显差异,P>0.05。结论:对急性牙髓炎患者采取活髓牙失活后根管治疗与拔髓后根管治疗的远期疗效无明显差异,但是前者治疗方案可明显减轻患者疼痛感。
Objective: To investigate the clinical effect of root canal therapy and root canal therapy after deactivation of vital pulp teeth. Methods: A total of 206 patients with acute pulpitis who were admitted to our hospital from May 2013 to October 2014 were randomly divided into routine group and experimental group with 103 cases in each group. The patients in the conventional group After root canal therapy, the patients in experimental group were treated with root canal therapy after inactivation, and the incidence of pain and long-term effect were compared between the two groups. Results: The incidence of pain was 1.94% and 7.77% respectively in the experimental group and the conventional group, P <0.05. There was no significant difference in the long-term efficacy between the experimental group and the conventional group (P> 0.05). Conclusion: There is no significant difference in the long-term efficacy of root canal treatment after root canal inactivation of acute pulpitis patients with root canal therapy. However, the former treatment can significantly reduce the pain sensation in patients.
