There are some differences between the surgical methods of pulpal hemodialysis and living pulp severance, patients need to take into account their own situation, as well as their personal needs, under the guidance of the doctor to choose the appropriate surgical method. 1. Pulp revascularization: Pulp revascularization is a procedure that protects the stem cells and active tissues around the root of the tooth through revascularization techniques, while introducing one’s own blood to make a biological scaffold that can stimulate the generation of a pulp-like tissue. This kind of pulp tissue can have the function of pulp and reach the level close to normal teeth. 2. Live Pulpotomy: Live Pulpotomy is to cut and remove the localized diseased crown pulp under local anesthesia, and cover the pulp with pulp capping agent to preserve the healthy root pulp tissue. Patients who wish to undergo pulp revascularization or pulpotomy are advised to consult their doctor for advice. Patients are advised to keep their teeth clean after the procedure and to seek medical attention in case of any dental discomfort.
