摘　　要：目的 评估三氧化矿物凝聚体（mineral trioxide aggragate,MTA）牙髓切断术治疗年轻恒牙不可复性牙髓炎的临床效果,为年轻恒牙不可复性牙髓炎的治疗提供新思路.方法 选取北京大学口腔医学院·口腔医院儿童口腔科就诊的26例患者,对其临床诊断为不可复性牙髓炎的26颗年轻恒牙应用MTA作为盖髓剂,根据切断牙髓部位的出血情况行部分或全部冠髓切断,术后1年随访,通过临床和X线片检查评估治疗效果.结果 术后1年,4例患者失访,其他22例患者（共计22颗患牙）进行了复查.22颗牙中20颗牙判为治愈或有效,临床成功率为91％（20/22）;13颗牙在X线片上可见钙化桥,钙化桥形成率为65％（13/20）.结论 MTA牙髓切断术是治疗年轻恒牙不可复性牙髓炎的有效方法,但长期疗效还需进一步观察.Objective To evaluate the preliminary clinical effect of mineral trioxide aggragate （MTA） pulpotomy on immature permanent teeth with irreversible pulpitis.Methods Twenty-six immature permanent teeth with irreversible pulpitis were recuited from Department of Pediatric Dentistry, Peking University School and Hospital of Stomatology.These teeth were treated with partial or full pulpotomy according to the condition of pulp bleeding.MTA was used as pulp capping material.Patients were recalled periodically after the treatment.Clinical and radiographic effects were evaluated.Results At one year follow-up, 20 teeth were evaluated as healed or healing, 2 teeth were evaluated as failure and 4 teeth were dropped out.The success rate was considered 91%（20/22）.A dentinal bridge was radiographcally observed underneath the pulpotomy site in 13 teeth（65%, 13/20）.Conclusions MTA pulpotomy is an effective method for the treatment of immature permanent teeth with irreversible pulpitis.But further research with longer follow up period is required.
