摘　　要：目的评估牙髓血运重建术治疗年轻恒磨牙慢性根尖周炎的临床疗效,为牙髓血运重建在年轻恒磨牙中的诊疗提供临床依据。方法选择2020年1-6月于青岛市市立医院口腔科就诊的年轻恒磨牙根尖周炎患者9例,年龄7~13岁,其中男3例、女6例。全部患者均采用牙髓血运重建术治疗,随访观察12~36个月,观察其根尖周病变愈合情况及牙根发育情况。结果9例患者在随访观察期间,7例成功、1例好转、1例失败,有效率88.9%。影像学检查显示:有效病例根尖周透射影消失,牙根长度增加,根尖孔闭合,根管壁也有不同程度的增厚。结论采用牙髓血运重建术治疗年轻恒磨牙的慢性根尖周炎是一种可行性较高的临床操作手段,可促进牙根延长、根尖孔闭合及根管壁增厚。Objective To evaluate the clinical effect of pulp revascularization in the treatment of immature permanent molars with complex root canal system,and to provide clinical basis for the diagnosis and treatment of pulp revascularization in young permanent molars.Methods A total of nine patients with apical periodontitis of immature permanent molars,aged 7 to 13 years old,who were treated at the Department of Stomatology,Qingdao Municipal Hospital between January 2020 and June 2020,were included in this study.The sample consisted of three male patients and six females.They were all treated with pulp revascularization and followed up for 12~36 months.The healing of periapical lesions and root development were observed and evaluated.Results During the follow-up observation period,seven cases were successful,while one case got improved,and one case failed,leading to the effective rate of 88.9%.Imaging examinations showed that in effective cases,the periapical radiolucency disappeared,while the root length increased,and the apical foramen closed.In addition,the root canal wall also thickened to varying degrees.Conclusions Pulp revascularization in the treatment of chronic apical periodontitis of immature permanent molars was a highly feasible clinical operation,which can promote root elongation,apical foramen closure and root canal wall thickening.
