Oral diseases are usually caused by external physical and chemical factors,the invasion of pathogens,dento-maxillofacial deformities and systemic diseases.Oral infections and orofacial pain triggered by oral diseases seriously reduce the quality of life.Pyroptosis is a kind of programmed cell death,which is characterized by swelling of the cell until the cell membrane ruptures,releasing the cell contents and activating a strong inflammatory response.Previous studies have shown that pyroptosis is widely involved in the occurrence and development of oral diseases.In this review,four types of cellular pyroptosis pathways are described in detail,including the canonical pathway,non-canonical pathway,caspase-3/8 mediated pathway and caspase independent pathway.Different pyroptosis pathways form complex signal networks,which regulate the functions of periodontal membrane cells,gingival fibroblasts,macrophages and other cells in the oral cavity,thus affecting the occurrence and development of oral diseases.This review summarizes the latest research about the pathways of pyroptosis and its roles in oral diseases,aiming to provide a theoretical basis and direction for searching effective methods to treat and prevent oral diseases.
