Abstract:

Summary：A new clinical procedure named “pulp revascularization” emerged when treating infected， non-vital， immature teeth. This procedure performed copious irrigation and followed by placement of the mixed antibiotics in the root canal to make sure of thorough disinfection. The blood clot formed in the canal provide a scaffold for the potentially remaining dental pulp stem cells and mesenchymal stem cells， which can proliferate and differentiate into odontoblasts and cementoblasts cells in the inducing of signal molecule and MTA to allow continued root development in terms of both length and thickness. In this article， the progress of laboratory and clinical research on dental pulp revascularization in recent years are reviewed.

Key words: dental pulp；revascularization；immature permanent teeth
