Oral ulcer is a common disease of oral mucosa, also known as oral ulcer. The pain is very obvious when it occurs, and it can self heal without treatment. There is a close relationship between recurrent oral ulcer and immunity. The incidence rate of oral ulcer is the highest in oral mucosal diseases. Common cold, indigestion, mental digestive system diseases and functional disorders are common. Patients with systemic diseases are prone to oral ulcers, mainly through the influence of immune system. Oral ulcer is related to gastric ulcer, duodenal ulcer, ulcerative colitis, localized enteritis, hepatitis, etc. Research shows that 30% – 48% of patients with oral ulcer have digestive tract diseases, such as abdominal distention, diarrhea or constipation. More than 9% of them have peptic ulcer.
Endocrine changes, some women often occur in the menstrual period, may be related to the decrease of estrogen in the body. Some women often have oral ulcer during menstruation or before and after menstruation, which can only be temporarily relieved by medication. When menstruation is performed next month, oral ulcer will appear as usual, and the pain is intolerable. At the same time, it is often accompanied by such annoying symptoms as dry mouth, upset, irritable and dry stool. Clinical studies have found that oral ulcer in menstrual period is mainly caused by the increase of progesterone level and the decrease of estrogen (progesterone, etc.).

Genetic factors, such as recurrent oral ulcer in both parents, about 80 & mdash; 90% of their children are sick, if one of their parents is sick, about 50 & mdash; 60% of their children are sick.
Other factors, such as lack of trace elements such as zinc, iron, folic acid, vitamin B12, malnutrition, can reduce the immune function and increase the possibility of recurrent oral ulcer. The virus may be the initiating factor of oral ulcer, but no antibody has been found in the serum of patients, and no virus has been isolated from the lesion of oral ulcer. The effect of bacteria on oral ulcer has been put forward for many years. Streptococcus sanguis and Helicobacter pylori are closely related to oral ulcer. The imbalance of the production and clearance of superoxide radicals, the imbalance of the proportion of thromboxane B2 and 6-keto-prostaglandin and the decrease of the overall level can lead to oral ulcer. Microcirculation disturbance leads to slow blood flow, low blood flow, dilation of capillary vein end diameter, local ischemia and hypoxia, which leads to mucosal membrane damage and ulcer formation. There is a certain correlation between the occurrence of RAU and the deficiency of zinc, iron and copper in serum. It is reported that quitting smoking can also induce oral ulcer. The ingredient in toothpaste, sodium 12 alkane sulfate (SLS), may stimulate mucous membrane and induce oral ulcer.
