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

The Clinical Efficacy Observation of Disposable Root Canal Treatment of Mandibular Pulp Necrosis and Chronic Root Inflammation Observation

目的探究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疗效。方法非随机选取2022年4月—2024年2月南京市江宁中医院收治的80例下颌第一磨牙牙髓坏死与慢性根尖周炎患者为研究对象,按治疗方案不同分为两组,各40例,观察组选择一次性根管治疗,对照组选择多次根管治疗,对比两组的治疗相关指标、治疗效果及疼痛程度。结果观察组疼痛消失时间、治疗所需时间、治疗次数均优于对照组,差异有统计学意义(P均<0.05)。观察组的总有效率为97.50%(39/40),高于对照组的75.00%(30/40),差异有统计学意义(χ^(2)=8.538,P<0.05)。观察组的疼痛程度较对照组更轻,差异有统计学意义(P<0.05)。结论在下颌第一磨牙牙髓坏死与慢性根尖周炎的治疗中,一次性根管治疗的有效性、安全性均较高。

Objective To explore the curative effect of one-time root canal on pulp necrosis and chronic periapical inflammation of mandibular first molar.Methods A total of eighty patients with pulp necrosis and chronic periapical periodontitis of mandibular first molar treated in Nanjing Jiangning Hospital of Traditional Chinese Medicine from April 2022 to February 2024 were non-randomly selected as the study objects and divided into two groups according to different treatment plans,with forty cases in each group.The observation group underwent one-time root canal treatment,while the control group underwent multiple root canal treatment.The therapeutic indexes,therapeutic effect and pain degree of the two groups were compared.Results The pain disappearance time,treatment time and treatment times in the observation group were better than those in the control group,and the differences were statistically significant(all P<0.05).The total effective rate of the observation group was 97.50%(39/40),higher than 75.00%(30/40)of the control group,and the difference was statistically significant(χ2=8.538,P<0.05).The degree of pain in the observation group was less than that in the control group,and the difference was statistically significant(P<0.05).Conclu⁃sion In the treatment of pulp necrosis and chronic periapical periodontitis of mandibular first molar,one-time root canal therapy is effective and safe.
