一次性根管治疗下颌第一磨牙牙髓坏死与慢性根尖周炎的临床疗效分析

Analysis of the clinical efficacy of pulp necrosis and chronic periapical periodontitis of mandibular first molar treated by single-visit root canal therapy

目的分析采用一次性根管治疗下颌第一磨牙牙髓坏死与慢性根尖周炎的临床疗效。方法180例下颌第一磨牙牙髓坏死与慢性根尖周炎患者作为研究对象,依据患者自主选择的治疗方案不同分为观察组与对照组,各90例。对照组患者采用多次根管治疗,观察组患者采用一次根管治疗。对比两组患者治疗6个月后的临床效果及疼痛消退和炎症消退时间。结果观察组治疗6个月后总有效率为94.44%,高于对照组的73.33%,差异有统计学意义(P<0.05)。观察组的疼痛消退时间和炎症消退时间分别为(5.91±1.15)、(4.41±1.07)d,均短于对照组的(8.28±1.07)、(7.88±1.69)d,差异有统计学意义(P<0.05)。结论采用一次性根管治疗下颌第一磨牙牙髓坏死与慢性根尖周炎的临床疗效好,可缩短患者的疼痛时长,消炎时间较短。

Objective To analyze the clinical efficacy of pulp necrosis and chronic periapical periodontitis of mandibular first molar treated by single-visit root canal therapy.Methods A total of 180 patients with pulp necrosis and chronic periapical periodontitis of the mandibular first molar were taken as the research subjects.According to the treatment scheme selected by the patients,they were divided into observation group and control group,with 90 cases in each group.Patients in the control group received multiple-visit root canal therapy,and patients in the observation group received single-visit root canal therapy.The clinical effects after 6 months of treatment,and the pain and inflammation subsided time of the two groups were compared.Results The total effective rate of the observation group after 6 months of treatment was 94.44%,which was higher than 73.33%of the control group,and the difference was statistically significant(P<0.05).The pain and inflammation subsided time in the observation group were(5.91±1.15)and(4.41±1.07)d,which were shorter than(8.28±1.07)and(7.88±1.69)d of the control group,and the difference was statistically significant(P<0.05).Conclusion Singlevisit root canal therapy provides good clinical efficacy on the treatment of pulp necrosis and chronic periapical periodontitis of mandibular first molar,and it can shorten the pain and inflammation subsided time of patients.
