Three clinical cases have been treated with the use of an apical plug of MTA for apexification. All three cases were central incisors that had suffered premature interruption of root development as a consequence of trauma. According to the treatment protocol, the root canals were rinsed with 5% NaOCl; then, calcium hydroxide paste was placed in the canals for 1 week. Consequently, the apical portion of the canal (4 mm) was filled with MTA. The remaining portion of the root canals was then closed with thermoplastic gutta-percha. At 6-month and 1-year follow-up period the clinical and radiographic appearance of the teeth showed resolution of the periapical lesions. MTA appears to be a valid option for apexification with its main advantage being the speed at which the treatment can be completed.
使用MTA根尖屏障进行根尖诱导成形术治疗了三例临床病例。所有三例均为因外伤导致牙根发育过早中断的中切牙。根据治疗方案，根管先用5%次氯酸钠冲洗；然后，在根管内放置氢氧化钙糊剂1周。随后，根管根尖部分（4毫米）用MTA充填。然后用热塑性牙胶封闭根管其余部分。在6个月和1年的随访期，牙齿的临床和影像学表现显示根尖周病变消退。MTA似乎是根尖诱导成形术的有效选择，其主要优点是治疗完成速度快。
