To examine the clinical and radiographic appearance of teeth with immature apices that were treated by single step procedure using mineral trioxide aggregate (MTA).
Creation of a physiological hard tissue barrier with calcium hydroxide in a nonvital tooth although quite predictable has certain limitations, such as the very long duration of the treatment spread over multiple visits and increased risk of root fracture. Plugging the root canal end with MTA has been advocated as an alternative treatment modality for open apices. The technique has been proven to be successful in many recently reported cases. The cases reported here present the successful treatment of two traumatized maxillary central incisors with open apices and periapical lesions using MTA. In this case report, MTA has been used to create a hard tissue barrier after disinfection of the root canal.
研究使用三氧化矿物凝聚体（MTA）通过单步程序治疗根尖未发育成熟牙齿的临床和影像学表现。
在无活力牙中用氢氧化钙形成生理性硬组织屏障虽颇具可预测性，但有一定局限性，比如治疗时间很长且需多次就诊，以及根折风险增加。有人主张用MTA充填根管末端作为开放根尖的一种替代治疗方式。该技术在最近许多报道的病例中已被证明是成功的。此处报道的病例展示了使用MTA成功治疗两颗上颌中切牙外伤导致的开放根尖和根尖周病变。在本病例报告中，根管消毒后使用MTA形成硬组织屏障。
