摘　　要：目的:评价牙髓血运重建术在牙髓坏死伴/不伴根尖周炎的年轻恒牙牙髓治疗中的临床疗效。方法:回顾进行牙髓血运重建术治疗的10颗患牙,术后每3~6个月复查,随访10~27个月。通过问诊、临床检查和影像学检查评估治疗前后,患牙不适临床症状的转归以及牙根发育的情况。结果:牙髓血运重建术后,所有患牙不适临床症状消失,临床有效率和患牙临床生存率达100%,且影像学检查显示根尖周病变愈合,牙根继续发育,根尖孔直径减小,牙根长度增加(P<0.05),根管壁厚度增加不显著(P>0.05)。结论:牙髓血运重建术在牙髓坏死伴/不伴根尖周炎年轻恒牙的治疗中取得了较好的临床疗效。Objective:To evaluate the clinical effect of dental pulp revascularization in the treatment of pulp necrosis in immature permanent teeth with or without periapical inflammation.Methods:Ten teeth treated with dental pulp revascularization were followed up for 10 to 27 months and revisited every 3 to 6 months.The clinical symptoms of teeth and the development of roots before and after treatment were evaluated through consultation,clinical examination and X-ray examination.Results:After dental pulp revascularization,all the clinical symptoms of the affected teeth disappeared,the periapical lesions healed,the clinical effective rate and the clinical survival rate of the affected teeth reached 100%,and the X-ray examination showed that periapical lesions healed,the root continued to develop,the diameter of the apical foramen decreased,and the root length increased(P<0.05),however the thickness of root did not increase significantly(P>0.05).Conclusion:Pulp revascularization is effective in the treatment of pulp necrosis in young permanent teeth with or without periapical periodontitis.
