Abstract:Curcumin is a natural phenolic compound with anti-inflammatory and anti-tumor effects. At present, it has made considerable achievements in the research of laryngeal cancer, liver cancer, periodontitis and other diseases. In recent years, nanoscale curcumin products prepared by freeze-drying and other methods have gradually attracted people's attention. In this paper, the research progress of curcumin and its nanoproducts in the treatment of oral cancer at home and abroad was reviewed. It was confirmed that curcumin can promote the apoptosis and autophagy of oral cancer cells. In addition, this review summarized the current research on curcumin and its nanoproducts combined with radiotherapy, chemotherapy, photodynamic, sonodynamic and other natural drugs in the treatment of oral cancer, and the preventive effect of curcumin on oral cancer, further affirming that curcumin has a broad application prospect as an anticancer drug. It is hoped to provide ideas for the prevention and treatment of oral cancer in the future.
