To examine the clinical and radiographic appearance of teeth that suffered premature interruption of root development and were treated by an mineral trioxide aggregate (MTA) apical plug technique.
Eleven teeth with immature root apices in 11 patients were treated nonsurgically by the manual application of MTA in the apical portion of the root canal under microscopic vision. Follow-up evaluations were performed at 1-2 years after treatment.
Mineral trioxide aggregate appears to be a valid material to obtain periradicular healing in teeth with open apices and necrotic pulps. Ten out of 11 cases were associated with periradicular health at follow-up evaluation.
研究牙根发育过早中断并采用三氧化矿物凝聚体（MTA）根尖充填技术治疗的牙齿的临床和影像学表现。
对11例患者的11颗根尖未发育成熟的牙齿，在显微镜直视下于根管根尖部手工应用MTA进行非手术治疗。治疗后1至2年进行随访评估。
三氧化矿物凝聚体似乎是一种有效的材料，可使根尖开放且牙髓坏死的牙齿实现根尖周愈合。在随访评估中，11例中有10例根尖周健康。
