Management of coronal discolouration following a regenerative endodontic procedure in a maxillary incisor

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.
