【摘要】：目的:通过对根尖孔未发育完全的年轻恒牙实施牙髓血运重建治疗,并追踪随访患牙9~24个月,观察牙髓血运重建术的临床疗效。方法:对9例(11颗牙)患牙进行常规开髓,清除坏死的牙髓组织,2.5%的次氯酸钠和17%的EDTA溶液冲洗后封入三联抗生素糊剂。待患牙临床症状消失后,对其进行牙髓血运重建术,严密冠方封闭,定期复诊观察。结果:9例(11颗牙)年轻恒牙经牙髓血运重建术治疗后,临床症状全部消失。其中,6颗牙根尖孔闭合,牙根发育,牙髓电活力测试有反应;4颗牙根尖孔闭合,牙根发育,牙髓电活力测试无反应;1颗牙治疗失败。结论:牙髓血运重建术能使牙根继续发育,为治疗牙髓炎症、坏死和根尖周感染的年轻恒牙提供了可选择的方法。
[Abstract]:Objective: to observe the clinical effect of pulp revascularization in young permanent teeth with incomplete apical foramen. Methods: 9 cases (11 teeth) were treated with conventional pulp opening, the dead pulp tissue was removed, 2.5% sodium hypochlorite and 17% EDTA solution were washed and sealed with triple antibiotic paste. After the clinical symptoms of the affected teeth disappeared, the pulp revascularization was performed, the crown was tightly closed, and the diagnosis was observed regularly. Results: the clinical symptoms of 9 cases (11 teeth) of young permanent teeth disappeared after pulp revascularization. Among them, 6 teeth had apical foramen closure, root development, pulp electrical vitality test, 4 teeth had apical foramen closure, root development, pulp electrical vitality test had no response, 1 tooth treatment failed. Conclusion: pulp revascularization can make the root continue to develop and provide an alternative method for the treatment of pulpitis, necrosis and periapical infection of young permanent teeth.
