Main goal of endodontic obturation is to create a fluid-tight seal along the length of the root canal system, from the coronal opening to the apical termination.
Apexogenesis is defined as the treatment of the vital pulp by capping or pulpotomy in order to permit continued growth of the root and closure of the open apex and Apexification is the method of inducing development of the root apex of an immature pulpless tooth by formation of oseocementum / bone like tissue.
