摘　　要：目的:探讨牙髓血运重建与根尖诱导成形术在年轻恒牙根尖周炎患者中的应用价值。方法:将年轻恒牙根尖周炎患者80例(患牙80颗)随机分为A组和B组各40例(患牙各40颗)。A组行牙髓血运重建术,B组行根尖诱导成形术,随访至术后1年。比较两组临床疗效、牙根长度、牙根面积及根尖孔大小的改变、牙根生长发育情况及并发症发生情况。结果:A组治疗显效率为82.50%,高于B组的60.00%(P<0.05);术后6个月,A组牙根长度和牙根面积增加值、根尖孔缩小值均大于B组(P<0.05);术后1年,两组牙根管壁厚度、牙冠跟比均高于术前,且A组牙根管壁厚度、牙冠跟比、牙骨质样组织沉积率均高于B组(P<0.05);两组不良反应发生率比较,差异无统计学意义(P>0.05)。结论:牙髓血运重建与根尖诱导成形术在年轻恒牙根尖周炎治疗中均能获得确切疗效,且安全性高,而牙髓血运重建术能够更好地提高牙骨质样组织沉积率,促进牙根生长。Objective:To investigate the application value of pulpal haemodilution reconstruction and apical induction plasty in patients with apical periodontitis in young permanent teeth.Methods:Eighty patients with apical periodontitis in young permanent teeth(80 teeth)were randomly divided into group A and group B with 40 teeth each.Group A underwent pulpal haemodialysis reconstruction and group B underwent apical induction plasty,and the patients were followed up for 1 year after the operation.The clinical efficacy,changes in root length,root area and apical foramen size,root growth and development,and complications were compared between the two groups.Results:The treatment efficacy of group A was higher than that of group B(82.50%vs 60.00%)(P<0.05).The increase values in root length and root area,and reduction in apical foramen size were greater in group A than the group B at postoperative 6 months(P<0.05).The thickness of the root canal wall and the crown-heel ratio in both groups were increased at postoperative1 year,and moreover,the thickness of the root canal wall,crown-heel ratio,and rate of deposition of cementum-like tissue were higher in group A than group B(P<0.05).The difference in the incidence of adverse reactions between the two groups showed no statistical significance(P>0.05).Conclusion:Pulpal haemodilution reconstruction and apical induction plasty can all achieve accurate efficacy and high safety in the treatment of apical periodontitis in young permanent teeth,while pulpal haemodilution reconstruction can better improve the rate of osteoid deposition and promote root growth.
