Pulpal necrosis and infection in an immature anterior tooth subsequent to traumatic injury is a challenging situation. Regenerative endodontics, resulting in continued development of the tooth, provides a biological response to this clinical challenge. Regenerative endodontic procedures require disinfection of the infected root canal and sealing of the pulp canal space. Mineral trioxide aggregate (MTA) provides a good seal, is biocompatible and allows the formation of a hard tissue to occur within the root canal. MTA, however, can lead to significant staining of the crown of the tooth that is difficult to mask. This case report describes the management of discolouration in an 11 year old girl subsequent to a regenerative endodontic procedure in an immature traumatized maxillary central incisor.
外伤后未成熟前牙的牙髓坏死和感染是一种具有挑战性的情况。再生牙髓治疗可使牙齿持续发育,为这一临床挑战提供了一种生物学应对方法。再生牙髓治疗程序需要对感染的根管进行消毒并封闭牙髓腔隙。三氧化矿物凝聚体(MTA)密封效果良好,具有生物相容性,并能使根管内形成硬组织。然而,MTA会导致牙齿冠部出现明显染色,难以掩饰。本病例报告描述了一名11岁女孩在未成熟的上颌中切牙外伤后进行再生牙髓治疗后牙齿变色的处理情况。
