Management of discolouration following revitalization endodontic procedures: A case series

Aim To discuss the causes and management of tooth crown discolouration following regenerative/revitalization endodontic therapy (RET) and to present the decision-making process affecting three RET-related cases of crown discolouration. This case series outlines several approaches used in the management of post-RET discolouration. The cases highlight the influence of the material used in creating a coronal seal on the choice and success of the management techniques provided. The first two cases highlight successful management of post-RET discolouration through the use of internal-external bleaching. The use of internal bleaching in the third case was not recommended; therefore, external bleaching followed by a direct composite veneer was carried out.
