摘　　要：目的:观察牙髓血运重建术治疗年轻恒牙牙髓坏死合并根尖周炎患儿的效果。方法:选取2021年2月至2024年1月该院收治的68例年轻恒牙牙髓坏死合并根尖周炎患儿进行前瞻性研究,按照随机数字表法将其分为观察组和对照组各34例。对照组采取常规根尖诱导成形术治疗,观察组采取牙髓血运重建术治疗。比较两组临床疗效,治疗前后牙根指标(牙根长度、根管壁厚度)水平、疼痛[视觉模拟评分法(VAS)]评分,以及并发症发生率。结果:观察组治疗总有效率为97.06%(33/34),高于对照组的73.53%(25/34),差异有统计学意义(P<0.05);治疗后,两组根管壁厚度、牙根长度均大于治疗前,且观察组大于对照组,差异有统计学意义(P<0.05);治疗后,两组VAS评分均低于治疗前,且观察组低于对照组,差异有统计学意义(P<0.05);观察组并发症发生率为5.88%(2/34),低于对照组的23.53%(8/34),差异有统计学意义(P<0.05)。结论:牙髓血运重建术治疗年轻恒牙牙髓坏死合并根尖周炎患儿可提高治疗总有效率,改善牙根指标水平,降低疼痛评分和并发症发生率,效果优于常规根尖诱导成形术治疗。Objective:To observe effects of dental pulp revascularization in treatment of young permanent teeth with pulp necrosis and periapical periodontitis.Methods:A prospective study was conducted on 68 children with pulp necrosis and periapical periodontitis of young permanent teeth admitted to this hospital from February 2021 to January 2024.According to the random number table method,they were divided into observation group and control group,34 cases in each group.The control group was treated with conventional apexification,while the observation group was treated with dental pulp revascularization.The clinical efficacy,the root index(root length,root canal wall thickness)levels and the pain[visual analogue scale(VAS)]score before and after the treatment,and the incidence of complications were compared between the two groups.Results:he total effective rate of the observation group was 97.06%(33/34),which was higher than 73.53%(25/34)of the control group,and the difference was statistically significant(P<0.05).After the treatment,the levels of root canal wall thickness and root length of the two groups were greater than those before the treatment,those of the observation group were greater than those in the control group,and the differences were statistically significant(P<0.05).After the treatment,the VAS scores of the two groups were lower than those before the treatment,that in the observation group was lower than that in the control group,and the differences were statistically significant(P<0.05).Further,the incidence of complications in the observation group was 5.88%(2/34),which was lower than 23.53%(8/34)in the control group,and the difference was statistically significant(P<0.05).Conclusions:Dental pulp revascularization in the treatment of pulp necrosis and periapical periodontitis in young permanent teeth can improve the total effective rate of treatment,improve the levels of root indexes,and reduce the pain scores and the incidence of complications.Moreover,it is superior to conventional apexification.
