  • Publication number: 20250242082
    Abstract: Methods of regenerating vital tooth tissue in situ after endodontic therapy include introducing a hydrogel scaffold into a root canal of a tooth in a patient after native pulp has been removed from the root canal. The hydrogel scaffold may comprise a sponge scaffold, and can be acellular. The hydrogel scaffold can contain chemotactic, angiogenic, neurogenic, and/or immunomodulatory biofactors that cause infiltration of endogenous cells from the patient into the root canal. Alternatively, such biofactors/drugs can be administered to the patient separately from the hydrogel scaffold. The hydrogel scaffold can fill the periapical space of an abscessed root.
    Type: Application
