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 evaluate the clinical effect of pulp revascularization for the immature permanent teeth with wide apical foramen. Methods: Eleven immature permanent teeth with wide apical foramens from 9 patients were selected. The pulp of teeth was exposed and the necrotic tissue was cleaned up using the oral surgery microscope. Triple antibiotic cataplasm were sealed in the root canals after irrigation with 2.5% sodium hypochlorite and 17% EDTA solution. Pulp revascularization was operated when the tooth had no clinical symptoms. The accesses of the cavities were filled with composite resins. Results: The clinical symptoms of 9 patients (11 teeth) disappeared after pulp revascularization, among which the periapical lesions of six teeth were healed and the apical foramens were narrowed with pulp vitality responses, the periapical lesions of four teeth were healed and the apical foramens were getting narrow without pulp vitality responses, and one tooth was failed. Conclusion: Pulp revascularization was an effective treatment for immature permanent teeth with wide apical foramen.
