Following traumatic injury, pulpal and periapical pathosis in an immature anterior tooth is common, and treating open apices in these situations is a persistent problem for pedodontists. This is because there is no apical constriction, which would prevent the obturated material from forming an excellent three-dimensional seal or adaption within the canal system. Mineral Trioxide Aggregate (MTA) offers a good choice when employed to create an apical barrier. In this case report, an open apex and periapical lesion involving maxillary right central incisor #21 with the MTA are shown with a six-week follow-up result after being treated for four weeks with triple antibiotic paste as an intra-canal medication. The successful healing of tooth 21 and the diminution of the periapical radiolucency at one-week follow-up were observed.
外伤后，未成熟前牙的牙髓和根尖周病变很常见，在这些情况下治疗开放根尖对儿童牙医来说一直是个难题。这是因为没有根尖狭窄，这会阻止充填材料在根管系统内形成良好的三维密封或适配。当用于形成根尖屏障时，矿物三氧化物凝聚体（MTA）是一个不错的选择。在本病例报告中，展示了一颗上颌右侧中切牙（#21）存在开放根尖和根尖周病变，先用三联抗生素糊剂作为根管内药物治疗四周，然后使用MTA治疗，随访六周后的结果。在一周随访时观察到21号牙成功愈合，根尖周透射区减小。
