目的分析一次性根管对外伤性冠折露髓牙的疗效情况。方法 73例外伤性冠折露髓牙患者,按照治疗方法不同将其分为对照组(36例,49颗牙)采用多次根管治疗及观察组(37例,51颗牙)采用一次性根管治疗,比较两组术后不良反应发生率及治疗成功率。结果观察组治疗成功率为98.04%,术后反应发生率为5.88%;对照组治疗成功率为95.92%,术后不良反应发生率为12.24%,两组比较差异均无统计学意义(P>0.05)。结论一次性根管治疗与多次根管治疗的疗效及术后不良反应发生率并无显著差异,但一次性根管治疗疗程更短、患者就诊次数更少,值得推广。
Objective To analyze the curative effect of disposable root canal on traumatic decoction of exposed crown. Methods Totally 73 cases of traumatic coronal pulp exposed patients were divided into the control group (36 cases, 49 teeth) according to different treatment methods. The patients were treated with multiple root canal therapy and the observation group (37 cases, 51 teeth) Root canal treatment, the incidence of postoperative adverse reactions and treatment success rate were compared between the two groups. Results The success rate of the observation group was 98.04%, the incidence of postoperative reaction was 5.88%. The success rate of the control group was 95.92%, the incidence of postoperative adverse reactions was 12.24%, there was no significant difference between the two groups (P> 0.05). Conclusions There is no significant difference between the one-time root canal therapy and the multiple root canal therapy and the incidence of postoperative adverse reactions. However, the one-time root canal therapy has a shorter course of treatment and less patient visits, which is worthy of popularization.
