比较一次法与多次法根管治疗在后牙慢性根尖周炎中的临床效果分析

The clinical effect of one-time and multiple root canal therapy in chronic apical periodontitis of posterior teeth

目的研究比较一次法与多次法根管治疗在后牙慢性根尖周炎中的临床效果。方法于2018年1月~2020年1月,选择某医院口腔科收治的后牙(磨牙)慢性根尖周炎患者120例作为研究对象,依据随机数字表法分为对照组60例、观察组60例,对照组实施多次法根管治疗,观察组实施一次法根管治疗,比较临床疗效、牙周状况指标、疼痛评分。结果临床总有效率观察组96.67%,对照组93.33%,比较无统计学差异(P>0.05)。治疗后,龈沟出血指数、菌斑指数、软垢指数观察组均低于对照组(P<0.05)。术后疼痛评分观察组高于对照组(P<0.05)。结论一次法根管治疗用于后牙慢性根尖周炎患者治疗中,可达到与多次法根管治疗相当的疗效,还可更加有效地改善患者牙周状况,减轻炎症反应。

Objective To study and compare the clinical effect of one-time and multiple root canal therapy in chronic apical periodontitis of posterior teeth.Methods from January 2018 to January 2020,120 patients with chronic apical periodontitis of posterior teeth admitted to department of stomatology at a hospital were selected as the research objects.According to the principle of voluntariness,they were divided into control group(60 cases)and observation group(60 cases).The control group was treated with multiple root canals,and the observation group was treated with one root canals.The clinical efficacy,periodontal status indicators and pain scores were compared.Results The total clinical effective rate was 96.67%in the observation group and 93.33%in the control group(P>0.05).After treatment,the bleeding index,plaque index and soft scale index in the observation group were lower than those in the control group(P<0.05).The postoperative pain score of the observation group was higher than that of the control group(P<0.05).Conclusion One-time root canal therapy for chronic apical periodontitis of posterior teeth can achieve the same effect as multiple root canal therapy.It also can improve the periodontal condition of patients more effectively and reduce inflammatory reaction.
