Abstract: Photodynamic therapy is a treatment method that uses photosensitizer to stimulate photodynamic reaction to produce singlet oxygen and other reactive oxygen species to selectively kill bacteria and destroy diseased tissues. Inorganic nanomaterials are a new type of materials，which can be used not only as photosensitizers themselves，but also as carriers to load photosensitizers to mediate photodynamic therapy. This article reviews the common inorganic nanomaterials and the research progress of photodynamic therapy mediated by inorganic nanomaterials in oral diseases.

Key words: photodynamic therapy, inorganic nanomaterials, dental decay, dental pulp disease, periodontal disease, oral cancer
