Intrinsic discolouration of the tooth following pulpal necrosis occurs due to the penetration of the hemolysed products of the erythrocytes into the dentinal tubules.1 Moreover, pulpal necrosis occurring during early stages of apexogenesis may result in formation of a blunderbuss root canal.2 Cases of trauma induced intrinsically discoloured non-vital tooth with open apex requires comprehensive endodontic, restorative and aesthetic management to restore their appearance and function. In particular, a single anterior discoloured tooth often presents as an aesthetic challenge as it is seldom satisfactorily managed by direct and indirect restorative modalities. Moreover, in children and adolescents, migration of the gingival margin can lead to deterioration in esthetics if definitive restorations are planned.3 The subjected case report presents the management of a trauma induced intrinsically discoloured non-vital open apex tooth by “walking bleach” technique along with the use of mineral trioxide aggregate (MTA) as a bleaching barrier material and as an apical plug. |
