Introduction

Under normal circumstances, oral ulcers are ulcerative injuries of the oral mucosa, which may be caused by various factors including vitamin deficiencies, mental stress, recurrent aphthous ulcers, oral candidiasis, Behçet's disease, and others. In daily life, it is important to maintain a balanced diet and ensure adequate intake of vitamins and minerals. In addition, regular oral examinations should be conducted to promptly detect and treat oral diseases.

Generally speaking, oral ulcers are ulcerative injuries of the oral mucosa. Severe oral ulcers may be caused by various factors including vitamin deficiency, mental stress, recurrent aphthous ulcers, oral candidiasis, and Behcet's disease. It is recommended to seek timely medical advice and undergo treatment under a doctor's guidance. A detailed analysis is as follows:

1. Vitamin Deficiency

The B-complex vitamins and vitamin C are crucial for maintaining the health of the oral mucosa. A deficiency in these vitamins may cause the oral mucosa to become fragile and more susceptible to damage, leading to severe oral ulcers. It is advisable to consume more leafy vegetables, fruits, and other foods rich in vitamins as part of a regular diet to supplement these nutrients.

2. Mental Stress

Long-term mental tension or excessive stress can impair immune system function and reduce the resistance of the oral mucosa, potentially causing severe oral ulcers. Engaging in physical exercise, meditation, and maintaining good sleep habits can help relax both the mind and body.

3. Recurrent Aphthous Ulcers

Recurrent aphthous ulcers may be triggered by genetic factors, immune system abnormalities, environmental influences, and others. These factors may lead to microcirculatory disturbances in the oral mucosa and localized immune suppression, resulting in periodic ulcer outbreaks. Symptoms may also include pain and a burning sensation. Treatment should follow medical advice and may involve the use of medications such as compound chlorhexidine mouthwash, dexamethasone oral adhesive tablets, and watermelon frost spray.

4. Oral Candidiasis

Oral candidiasis is commonly caused by Candida infection and is frequently seen in individuals with weakened immune systems. Candida can proliferate on the oral mucosa, damaging the mucosal tissue and causing severe oral ulcers. Accompanying symptoms may include pain and swelling. Under a doctor's recommendation, medications such as nystatin tablets, fluconazole capsules, and sodium bicarbonate solution may be used to alleviate symptoms.

5. Behcet's Disease

Behcet's disease is a systemic autoimmune disorder potentially linked to genetic, infectious, and environmental factors. This condition may lead to immune system dysfunction, which attacks the oral mucosa and causes ulcers. Additional symptoms may include genital ulcers, uveitis, and arthritis. It is recommended to undergo treatment under medical supervision with medications such as prednisolone tablets, azathioprine tablets, and thalidomide tablets.

In daily life, maintaining a balanced diet to ensure adequate intake of vitamins and minerals is essential. Additionally, regular dental checkups should be conducted to promptly detect and treat oral diseases.
