Aphthous ulcers can also be known as canker sores, are a common and benign condition that affects the oral mucosa. They are characterized by the formation of painful, shallow, round or oval-shaped ulcers on the inside of the lips, cheeks, tongue, and soft palate. The ulcers typically have a yellow or gray center and a red border and can range in the size from a few mm to over a cm in diameter.
Aphthous ulcers are a common condition, affecting up to 20 percent of population at some point in their lives. They are generally seen in individuals between the ages of 10 and 40 years old. Women are more commonly than men to develop aphthous ulcers. The exact cause of the aphthous ulcers is not generally understood, but it is believed to involve a complex interplay of genetic, immunologic, and environmental factors.
There is evidence to suggest that aphthous ulcers may have a genetic component, as the condition often runs in families. Some studies suggest that aphthous ulcers may be caused by an overactive immune response to oral mucosal antigens or a deficiency in T-cell subpopulations. Trauma to the oral mucosa, such as from biting or brushing too hard, can also trigger the development of aphthous ulcers.
Epidemiology
Aphthous ulcers can also be known as canker sores, are a common oral mucosal disease characterized by painful, recurrent, and small ulcerations. The epidemiology of aphthous ulcers is complex and not completely understood, but some factors that may contribute to their occurrence are:
Prevalence: Aphthous ulcers are a common condition, with a prevalence ranging from 5% to 66% of the general population, depending on age, geographic location, and ethnicity.
Age: Aphthous ulcers are more common in young adults, with a peak incidence between 10 and 40 years of age. Children under the age of 5 are rarely affected.
Gender: Aphthous ulcers occur more frequently in women than in men.
Ethnicity: There is evidence to suggest that aphthous ulcers are more common in people of certain ethnicities, including
Caucasians and Asians, and less common in African Americans.
Genetics: There is a genetic component to aphthous ulcers, with a higher incidence in families with a history of the condition.
Immune system: Aphthous ulcers have been linked to immune system dysfunction, such as deficiencies in T-cell subpopulations or an overactive immune response to oral mucosal antigens.
Stress: Psychological stress has been associated with an increased risk of developing aphthous ulcers.
Trauma: Trauma to the oral mucosa, such as biting the inside of the cheek or brushing too hard, can trigger the development of aphthous ulcers.
Anatomy
Pathophysiology
The development of aphthous ulcerations is primarily caused by dysfunction of T-cell mediated immunity, although the destruction of the mucosal epithelium may also involve mast cell and neutrophil -mediated responses. The lesions are associated with changes in several intercellular mediators, including increases in tumor necrosis factor-alpha, interferon gamma, interleukins (IL)-2, IL-4, and IL-5 as well as various types of adhesion molecules responsible for epithelial integrity and cell communication.
This inflammatory process leads to the formation of a pseudomembrane that contains bacteria, fibrinous exudate, necrotic mucosal and inflammatory cells. Aphthous ulcers typically occur on the non-keratinized oral mucosa, like as along the buccal/labial surfaces, soft palate, floor of mouth, lateral or ventral surface of the tongue, tonsillar fauces, free (unattached or marginal) gingiva adjacent to teeth, and alveolar gingiva in the mandibular and maxillary sulci. In contrast, ulcerations caused by herpes simplex virus (HSV) typically involve keratinized mucosal surfaces, like as the dorsum and attached gingiva of the lips, tongue and hard palate.
Etiology
The exact cause of the aphthous ulcers is not generally understood, but it is believed to be a multifactorial process involving genetic, immunologic, and environmental factors. Here are some of the etiological factors that have been proposed:
Genetics: There is evidence to suggest that aphthous ulcers may have a genetic component, as the condition often runs in families.
Immune system dysfunction: Some studies suggest that aphthous ulcers may be caused by an overactive immune response to oral mucosal antigens or a deficiency in T-cell subpopulations.
Epithelial barrier dysfunction: A breakdown of the epithelial barrier lining the oral mucosa may allow for bacteria and other irritants to penetrate the mucosal surface, leading to inflammation and ulceration.
Viral infections: Certain viruses, such as herpes simplex virus, may play a role in the development of aphthous ulcers.
Trauma: Trauma to the oral mucosa, such as from biting or brushing too hard, can trigger the development of aphthous ulcers.
Hormonal changes: The hormonal changes, such as those that occur during menstruation, may be a trigger for some individuals.
Nutritional deficiencies: The deficiencies in vitamins and minerals, such as folic acid, iron and vitamin B12, have been linked to the development of aphthous ulcers in some individuals.
Stress: Psychological stress has been associated with an increased risk of developing aphthous ulcers.
Genetics
Prognostic Factors
Aphthous ulcers are generally considered to be a benign condition that resolves on its own within a few days to weeks. However, there are certain factors that may influence the prognosis of the condition. Here are some examples:
Severity: The size and number of aphthous ulcers can affect the severity of symptoms and the duration of the condition. Larger and more numerous ulcers may take longer to heal and be more painful than smaller or single ulcers.
Recurrence: Aphthous ulcers tend to recur in some individuals, with varying frequency and severity. Those who experience frequent or severe recurrences may require more aggressive management strategies to control the condition.
Location: The location of the aphthous ulcer can impact the prognosis. Ulcers that occur in areas where they are frequently irritated, such as on the tongue or on the inside of the cheek, may take longer to heal and be more painful than those in less frequently irritated areas.
Underlying conditions: Some underlying conditions, such as inflammatory bowel disease, HIV/AIDS, and Behcet’s disease, may be associated with increased risk of developing aphthous ulcers and may affect the prognosis of the condition.
Treatment: Treatment options for aphthous ulcers can vary in effectiveness and may impact the duration and severity of the condition. Treatment that is started early in the course of the condition may be more effective at reducing symptoms and promoting healing.

Treatment Paradigm
There is no cure for aphthous ulcers, but several treatments can help alleviate symptoms and speed up healing. The treatment paradigm for aphthous ulcers includes:
Topical analgesics: Over-the-counter topical analgesics, such as benzocaine and lidocaine, can help relieve pain and discomfort associated with aphthous ulcers. These products can be applied directly to the affected area and may be available as gels, sprays, or lozenges.
Topical corticosteroids: Topical corticosteroids can help reduce inflammation and promote healing of aphthous ulcers. These medications are available in gel or paste form and are usually applied directly to the ulcer.
Mouthwashes: Antimicrobial mouthwashes, such as those containing chlorhexidine, can help by reducing the risk of infection and speed up healing of aphthous ulcers. Additionally, mouthwashes containing anesthetic agents can help relieve pain and discomfort.
Nutritional supplements: Some research suggests that nutritional deficiencies, particularly of vitamin B12, iron, and folate, may contribute to the development of aphthous ulcers. Supplementation with these nutrients may help reduce the frequency and severity of ulcers.
Systemic corticosteroids: In severe cases of aphthous ulcers, systemic corticosteroids may be prescribed. However, these medications have significant side effects and are typically reserved for cases that do not respond to other treatments.
