ABSTRACT:
A method for repairing a tooth through the partial amputation of the coronal pulp at the orifices of the pulp canals, the arresting of hemorrhaging from the exposed cut ends of the pulpal tissue, and the fixing of those exposed cut ends by applying thereto a composition containing ferric ions, such as ferric sulfate and ferric subsulfate. The preferred composition can also be used for arresting hemorrhaging from the exposed cut ends of the pulpal tissue left in the pulp canals, in which case bleeding control and tissue fixation can be implemented simultaneously. The preferable use of a syringe-type controlled diffusion medicament applicator to infuse the preferred composition into tissue at the exposed cut ends of the pulpal tissue is also disclosed. Following tissue fixation, the barrier regions of fixed tissue between the empty coronal pulp chamber and vital pulp tissue remaining in the pulp canals are sealed from the coronal pulp chamber using a cement base, and the original tooth profile is restored, either by filling or capping.
