摘　　要：目的:观察牙髓血运重建术治疗感染年轻恒牙的临床疗效。方法:选择牙髓坏死或根尖周炎的年轻恒牙10颗,使用三联抗生素进行彻底根管消毒,建立无机三氧化物聚合体(MTA)屏障,进行牙髓血运重建术。通过术前和术后的X线片对比,评价根尖周病变和牙根发育情况的改变。结果:术后24个月,X线片显示10例患牙根尖周病变均完全消失。9例牙根增长,根管壁增厚,根尖聚拢;1例牙根未见明显增长,但管壁增厚,根尖闭合。结论:牙髓血运重建术在治疗感染年轻恒牙上具有较传统根尖诱导成形术和根尖屏障术明显的优势。Objective：To observe the clinical curative effect of pulp revascularization in the treatment of infections in immature permanent teeth. Methods：Select the pulp necrosis or periapical periodontitis 10 immature permanent teeth, using triple antibiotic thorough disinfection of root canal, mineral trioxide aggregate（MTA） barrier, pulp revascularization. Through the X-ray contrast before and after surgery, evaluate the development of periapical lesions and the root of change. Results：24 months after operation, the X-ray ifndings showed 10 cases of periapical lesions were completely disappeared. 9 cases of root growth, root canal wall thickening, apical together;1 cases of root no obvious growth, but the wall thickening, apical closure. Conclusions：Pulp revascularization has the advantage of traditional apexiifcation and apical barrier was obvious in the treatment of infections in immature permanent teeth.
