摘　　要：目的:评价因外伤、发育畸形所致根尖周炎或牙髓坏死的年轻恒牙牙髓血运重建术后的疗效及影响因素。方法:回顾分析66例因根尖周炎或牙髓坏死行血运重建治疗的年轻恒牙,采用Mimics软件重建患牙治疗前后的根尖周病损三维模型并测量体积,采用Dolphin软件测量患牙治疗前后的牙根长度、根管壁厚度及根尖孔大小,评估治疗后患牙根尖周病损的愈合情况及牙根发育情况,并对影响预后的因素进行探究。结果:40例患牙治愈(60.6%),24例患牙好转(36.4%),2例患牙失败(3%),术前炎症状态对牙根发育有显著影响(P<0.05)。结论:牙髓血运重建术能有效促进年轻恒牙的根尖周病损愈合,实现牙根的继续发育,术前炎症状态会影响其疗效。Objective:To evaluate the clinical effects of pulp revascularization of the immature permanent teeth with periapical lesions or pulp necrosis caused by the trauma or the dens evaginatus.Another purpose of the present study was to investigate the factors which may affect the treatment.Methods:66 cases of periapical lesions or pulp necrosis in immature permanent teeth were collected and treated by pulp revascularization.Mimics software was used to reconstruct a three-dimensional model of the periapical lesion before and after the treatment of the affected tooth.Then the volume of the apical lesions were measured.Dolphin software was used to measure the root length,the thickness of the root canal wall and apical foramen size before and after the treatment of the affected teeth.And to evaluate the factors which may affect the treatment.Results:According to the efficacy assessment criteria,40 teeth were evaluated as“cured”(60.6%),24 teeth as“improved”(36.4%),and two teeth as“ineffective”(3%).The preoperative inflammatory status significantly affected the root development(P<0.05).Conclusions:Pulp revascularization effectively promoted the healing of periapical lesions and achieved continuous root development.The preoperative inflammatory status can affect the root development.
