摘　　要：目的观察牙髓血运重建术对年轻恒牙根尖周炎的治疗效果。方法选取7~14岁13例单根管年轻恒牙慢性根尖周炎患者,共13颗患牙,常规根管消炎后行牙髓血运重建术,以后定期复诊。结果经过18个月以上的复诊观察,13例患者临床症状全部消失。13颗患牙牙根均得到不同程度的发育,其中9颗牙根尖孔闭合,牙齿基本发育完成,4颗牙根尖孔较前缩小但未闭合;13例患者中有4例出现根管钙化,3例患者冷诊有反应。结论年轻恒牙慢性根尖周炎患者行牙髓血运重建术有效且成功率高。Objective To observe the clinical effects on pulp revascularization of immature teeth with chronic apical periodontitis.Methods Thirteen patients aged 7-14 years with single root canal and immature permanent teeth with apical periodontitis were enrolled. A total of 13 affected tooth were treated with endodontic revascularization after routine root canal anti-inflammatory treatment. They were required to return regularly for observation.Results After a postoperative observation of more than 18 months, all the clinical symptoms of 13 immature permanent teeth disappeared after pulp revascularization. The 13 tooth all developed to different degrees, among which 9 tooth basically developed with apical hole closure, and the root apical orifices of 4 tooth were reduced but not closed. Four of the 13 patients showed calcification in the root canal, and three patients showed responses to pulp cooling test.Conclusion Pulp revascularization is effective and successful in young permanent teeth with chronic periapical periodontitis.
