Mouth ulcers are painful lesions on the lining of the mouth that can vary in size, shape, and depth. They can be primary (such as aphthous ulcers) or secondary (caused by infections, trauma, or systemic diseases). Ulcers can cause symptoms such as burning, itching, bleeding, and difficulty eating. These lesions can have a negative impact on the patient’s quality of life, and can cause food refusal and a deterioration in overall health.
History of the disease and interesting historical facts
The first mentions of mouth ulcers date back to the time of Hippocrates, who described various diseases associated with the oral cavity. In ancient times, mouth ulcers were believed to be a consequence of poor hygiene, but with the development of medical knowledge, the complex nature of these formations was revealed. For example, in medieval Europe, ulcers were associated with various forms of infectious diseases. By the 19th century, with the active development of dentistry, there was a breakthrough in understanding the causes of ulcers, and active development of methods for their treatment began. Research conducted in the 20th and 21st centuries showed that ulcers can be associated with syndromes such as Crohn's disease, celiac disease, and many other disorders.
Epidemiology
According to the World Health Organization, oral ulcers are common in about 20% of the population to varying degrees. In clinical practice, various types of ulcers are encountered, the most common of which are aphthous ulcers, which affect about 1-3% of the population in developed countries. Epidemiological studies show that ulcers occur more often in women and young people, although cases are possible in older age groups. In patients with chronic diseases, the frequency and severity of ulcers increase, so these data are of particular importance for monitoring and preventing this condition.
Genetic predisposition to this disease
Research shows that genetic predisposition plays a significant role in the development of oral ulcers. Certain mutations in genes responsible for the immune response and inflammation may increase the risk of ulcers. There is evidence of a link between the HLA (human leukocyte antigen) gene and predisposition to aphthous ulcers. For example, certain alleles of HLA-B15, HLA-B51 and HLA-DR2 may be associated with an increased incidence of these diseases. Research has also revealed the influence of genes that control the synthesis of various cytokines, which may affect inflammatory processes in the oral mucosa.
Risk factors for the development of this disease
Mouth ulcers can be caused by a number of factors, including:
- Physical factors: injuries, burns, mechanical irritation (for example, damage from teeth or dentures).
- Chemical factors: exposure to acids and alkalis, allergic reactions to dental materials.
- Infectious agents: viruses (eg, herpes virus), bacteria (streptococci) and fungi (Candida spp.).
- Autoimmune diseases: such as Behcet's disease and systemic lupus erythematosus.
- Heredity: a predisposition to developing ulcers in the family.
- Lifestyle: stress, alcohol and smoking abuse, lack of vitamins and dietary irregularities.
Diagnosis of this disease
To diagnose oral ulcers, the following aspects must be taken into account:
- The main symptoms are the presence of painful ulcers, which can be single or multiple, most often oval or round in shape, whitish or yellowish in color with a red border.
- Laboratory tests: Blood collection and serological tests are performed to detect primary diseases such as HIV, syphilis or syphilis.
- Radiological examinations: X-rays are used when deeper tissue damage is suspected.
- Other types of diagnostics: ulcer biopsy is indicated if malignant processes are suspected.
- Differential diagnosis: includes exclusion of other oral diseases such as candidiasis, stomatitis, viral infections and malignancies.
Treatment
Treatment for mouth ulcers depends on the cause and may include:
- General treatment: Includes recommendations to improve oral hygiene, use a soft toothbrush and avoid irritating areas.
- Pharmacological treatment: use of local anesthetics (eg, lidocaine), antiseptics (eg, chlorhexidine), and corticosteroids to relieve inflammation.
- Surgical treatment: extremely rare, may be required if there is no improvement or complications occur.
- Other treatments: Physical therapy procedures such as UHF therapy.
List of medications used to treat this disease
The medications used will include:
- Antiseptics: Chlorhexidine bigluconate.
- Anesthetics: Lidocaine gel.
- Corticosteroids: Beclomethasone, Dexamethasone.
- Immunomodulators: Topical application, eg, tacrolimus.
- Drugs for the treatment of autoimmune diseases: methotrexate or cyclosporine, if indicated.
Disease monitoring
Management of mouth ulcers involves regular dental visits and monitoring of physiological changes. The prognosis for most patients is favorable, especially with timely therapy. However, complications such as repeated relapses and the development of more serious diseases associated with systemic inflammation or autoimmune conditions are possible.
Age-related features of the disease
Mouth ulcers can occur at any age, however:
- In children: aphthous ulcers caused by viral infections or injuries are often observed.
- In adolescents: there may be a connection with changes in hormonal levels, stress and irregular eating habits.
- In adults: aphthous ulcers are most often associated with illness, stress, and other systemic disorders.
- In the elderly: ulcer complexity may be associated with concomitant diseases, decreased immunity and poor oral hygiene.
Questions and Answers
- What are the main causes of mouth ulcers? Ulcers can occur due to injury, infection, stress, vitamin deficiency, or underlying medical conditions.
- How long does it take for mouth ulcers to heal? In most cases, ulcers heal within 1 to 3 weeks, but this can vary depending on the cause.
- Can mouth ulcers be prevented? Maintaining good oral hygiene, eating a healthy diet, and managing stress can reduce the risk of developing ulcers.
- When should you see a doctor? If the ulcers do not go away within a few weeks or get worse, you should see a doctor for further evaluation.
- Can mouth ulcers be a sign of serious illnesses? Yes, ulcers can indicate more serious conditions such as autoimmune diseases, so it is important to get diagnosed promptly.
