Research progress of dental pulp regeneration treatment

Abstract

The dental pulp is the only soft tissue structure within the tooth, serving functions such as sensation and nutrition. However, the dental pulp is highly susceptible to necrosis due to external factors. Currently, root canal therapy is the most commonly used treatment for pulp necrosis. Nevertheless, teeth treated with root canal therapy are prone to secondary infections and adverse outcomes like vertical root fractures. Regenerative endodontic therapy has emerged as a solution, aiming to replace damaged tooth structures, including dentin, root structure, and the pulp-dentin complex cells. This approach demonstrates significant advantages in addressing clinical symptoms and achieving regeneration of the root and even the pulp. Since the discovery of dental pulp stem cells, regenerative endodontic therapy has gained new momentum. Advances in cell transplantation and cell homing techniques have rapidly developed, showing promising potential for clinical applications.
