  • Publication number: 20220287922
    Abstract: A dentin regenerative cell culture that can bring about a rapid regeneration of dentin in a deficit region. In the treatment of a tooth using the dentin regenerative cell culture, a root canal where a pulpectomy has been performed is filled with a root canal filler containing dental pulp stem cells. The dentin regenerative cell culture is then implanted in the deficit region of dentin, and temporary sealing with a packing is carried out. The dentin regenerative cell culture is formed three-dimensionally in conformity with the shape of the deficit region with the coalescence of cell masses of a plurality of odontoblasts, and thus the dentin regeneration is well promoted. In addition, gaps between the dentin regenerative cell culture and biological tissue can be rapidly filled. Infection due to bacterial infiltration can thereby be prevented.
