Immediate core buildup of endodontically treated teeth: the rest of the seal.

One primary objective of endodontic therapy is to establish an adequate seal with the root canal filling material. The placement of an immediate amalgam buildup at obturation, in conjunction with rubber dam isolation, allows an endodontic seal to be extended from the foramen to the cavosurface margin. As a result of this immediate buildup, the length of the seal and the longevity of the endodontic treatment are presumably extended. This article describes an effective means of performing the immediate core buildup of endodontically treated teeth.
