[Research progress in autophagy in the development of pulp inflammation and dental pulp injury reparation and regeneration].

Pulpitis is an infectious disease characterized by persistent inflammation of dental pulp and severe pain of patients, root canal treatment increases the risk of tooth fracture, discoloration and reinfection. Therefore, pulp injury repair and pulp regeneration become the new targets of pulpitis treatment. Autophagy is considered as an important defense and protective mechanism, thus plays an important role in preventing the host from excessive inflammatory reaction. There are few reports on the regulative mechanisms and therapeutic strategies of autophagy on pulp inflammation progression, therefore, this paper reviewed the role of autophagy on the progression of pulpitis, also reviewed the research progress of autophagy on dental pulp injury repair and regeneration, aiming to provide theoretical support for further research and clinical application.
