摘　　要：目的比较牙髓血管再生术与根尖诱导成形术治疗年轻恒牙牙髓坏死的效果。方法回顾性抽取2021年1月至2024年1月郑州大学第一附属医院收治的年轻恒牙牙髓坏死患者82例,其中43例行牙髓血管再生术治疗(A组),39例行根尖诱导成形术治疗(B组)。比较两组治疗效果及并发症发生率,比较两组手术前后患牙根壁厚度、根管长度、牙髓电活力(EPT)及牙骨样沉积率。结果A组总有效率(95.35%,41/43)高于B组(76.92%,30/39),P<0.05。术后1、6、12个月,两组患牙根壁厚度、根管长度长于术前,两组EPT低于术前(P<0.05);术后1、6、12个月,A组患牙根壁厚度、根管长度、牙骨样沉积率高于B组,EPT低于B组(P<0.05)。A组并发症总发生率(4.65%,2/43)低于B组(20.51%,8/39),P<0.05。结论牙髓血管再生术的治疗效果优于根尖诱导成形术,更有利于牙根生长发育。ObjectiveTo compare the effect of dental pulp revascularization and apexification in the treatment of dental pulp necrosis in young permanent teeth.MethodsA total of 82 patients with dental pulp necrosis in young permanent teeth admitted to the First Affiliated Hospital of Zhengzhou University from January 2021 to January 2024 were retrospectively selected.Among them,43 patients underwent dental pulp revascularization(group A),and 39 patients underwent apexification(group B).The treatment effect and incidence of complications of the two groups were compared.The root wall thickness,root canal length,electric pulp testing(EPT)and cementoid deposition rate of the affected teeth before and after surgery of the two groups were compared.ResultsThe total effective rate of the group A(95.35%,41/43)was higher than that of the group B(76.92%,30/39),P<0.05.At 1 month,6 months and 12 months after surgery,the root wall thickness and root canal length of the two groups were longer than those before surgery(P<0.05),while the EPT of the two groups were lower than those before surgery(P<0.05).One month,6 months and 12 months after surgery,the root wall thickness,root canal length and cementoid deposition rate of the affected teeth in the group A were higher than those in the group B,while the EPT of the group A was lower than that of the group B(P<0.05).The total incidence of complications in the group A(4.65%,2/43)was lower than that in the group B(20.51%,8/39),P<0.05.ConclusionsCompared with apexification,dental pulp revascularization has better effect in the treatment of dental pulp necrosis in young permanent teeth,and it is more conducive to growth and development of root.
