Overview

Oral ulcers, commonly known as "mouth sores", are a common ulcerative injury disease that occurs in the oral mucosa. They are more common in the inner side of the lips, tongue, tongue ventral side, buccal mucosa, vestibule groove, soft palate and other parts. The mucosa in these parts lacks a keratinized layer or has poor keratinization. Tongue ulcers refer to oral ulcers that occur on the tongue and the ventral part of the tongue. When oral ulcers occur, the pain is severe and there is obvious local burning pain. In severe cases, it can affect eating and speaking, causing great inconvenience to daily life. It may be complicated by bad breath, chronic pharyngitis, constipation, headache, dizziness, nausea, fatigue, irritability, fever, swollen lymph nodes and other systemic symptoms.

Causes and common diseases

The occurrence of oral ulcers is the result of the combined action of multiple factors, including local trauma, mental stress, food, drugs, malnutrition, changes in hormone levels and lack of vitamins or trace elements. Systemic diseases, genetics, immunity and microorganisms may play an important role in the occurrence and development of oral ulcers. Lack of trace elements such as zinc and iron, lack of folic acid, vitamin B12 and malnutrition can reduce immune function and increase the likelihood of oral ulcers. Bacteria such as Streptococcus sanguinis and Helicobacter pylori are also closely related to oral ulcers. Oral ulcers usually indicate that the body may have potential systemic diseases. Oral ulcers are related to gastric ulcers, duodenal ulcers, ulcerative colitis, regional enteritis, hepatitis, women's menstruation, vitamin B malabsorption, autonomic nervous system dysfunction, etc.

Recurrent oral ulcers are medically known as recurrent aphthous ulcers. They are the most common ulcerative lesions in oral mucosal diseases, with a prevalence rate of 10%-30% in the population. They are characterized by periodic attacks with varying intervals between attacks. The ulcers are prone to occur on the lips, tongue, cheeks, floor of mouth, soft palate, pharynx, etc. The cause of recurrent aphthous ulcer is not completely clear and is relatively complex. The following factors can be summarized:

1. Endocrine changes Some women experience oral ulcers during their menstrual period or before and after their menstrual period, which are extremely painful. At the same time, they are often accompanied by annoying symptoms such as dry mouth, irritability, irritability, and dry stools.

2. Genetic factors: If both parents suffer from recurrent oral ulcers, their children will have about 80-90% of the disease. If one of the parents suffers from the disease, their children will have about 50-60% of the disease.

3. Digestive system diseases and functional disorders Patients with systemic diseases are prone to oral ulcers, which mainly cause disease by affecting the immune system.

4. Mental factors: Some patients develop the disease when they are under mental stress, mood swings, or poor sleep, which is related to autonomic dysfunction.

5. 5. Other factors such as lack of trace elements zinc, iron, folic acid, vitamin B12, malnutrition, etc. can reduce immune function and increase the possibility of recurrent oral ulcers.
