2. Oral leukokeratosis: Most of them are caused by long-term mechanical stimulation or chemical stimulation, such as smoking, chewing betel nut, etc., which can also lead to white mucous membrane in the mouth.
3. Oral lichen planus: the etiology is still unclear, it may be related to immune factors, genetic factors, viral infections, neuropsychiatric factors, etc. It may lead to the appearance of round polygonal oral mucosa with clear boundaries and waxy film on the surface.
4. AIDS: It is a sexually transmitted disease caused by human immunodeficiency virus infection, which may lead to the formation of vertical folds or white grayish-white patches on the bilateral tongue edges.
5. Syphilis: Mucous membrane plaques caused by stage II syphilis may also appear as white, grayish-white raised plaques, causing white mucous membranes in the mouth.
