Study Notes
Aphthous Ulcers
- Aphthous Ulcers: are small, painful sores that occur inside the mouth
- Types of Aphthous Ulcers: Four types: Minor, Major, Herpetiform, and Recurrent Aphthous Ulcers
-
Minor Aphthous Ulcers: Are the most common type
- Occur on the movable mucosa (inside of the cheeks, lips, gums, and under the tongue)
- Usually heal on their own within 7-10 days
-
Major Aphthous Ulcers: Are less common than minor aphthous ulcers.
- Occur on the movable mucosa or fixed mucosa (roof of the mouth or back of the throat).
- Are deeper and more painful than minor ulcers. Healed ulcers often leave visible scars
- May take several weeks to heal completely
-
Herpetiform Aphthous Ulcers: Are the least common type
- Are tiny ulcers (1-2mm) and often asymptomatic
- Resemble ulcers caused by herpes simplex virus because they clump together in groups
- Occur on the movable or fixed mucosa
-
Recurrent Aphthous Ulcers: Are also known as "canker sores"
- Can affect people of any age, but are more common in women than men
- Have many precipitating factors, such as trauma, certain foods, menstruation, vitamin deficiencies, systemic diseases, tobacco cessation, medications, and stress
- May be caused by a potential genetic predisposition and are often seen in families
- Immunologic pathogenesis: T-cytotoxic cells are responsible for ulceration
- Often have a prodromal period of 1-2 days with burning or tingling sensation
Aphthous Ulcers
-
Aphthous ulcers are common, painful sores that appear in the mouth.
-
There are four main types of aphthous ulcers: minor, major, herpetiform, and recurrent aphthous ulcers.
Minor Aphthous Ulcers
- Minor aphthous ulcers are the most common type.
- They occur on the movable mucosa of the mouth.
- They are usually less than 1cm in size.
- They heal within 7-10 days without scarring.
Major Aphthous Ulcers
- Major aphthous ulcers are less common than minor aphthous ulcers.
- They are deeper and more painful than minor aphthous ulcers.
- They are often located on the posterior mucosa, but can also occur on the anterior mucosa.
- They can take several weeks to heal and may leave scars.
Herpetiform Aphthous Ulcers
- Herpetiform aphthous ulcers are the least common type.
- They are very small, typically 1-2mm in size.
- They occur in clusters, resembling herpes simplex virus lesions.
- They are usually asymptomatic.
- They are thought to be caused by the herpes simplex virus.
Recurrent Aphthous Ulcers
- Recurrent aphthous ulcers, also known as "canker sores," are a chronic condition.
- They occur repeatedly in the same location.
- They are often associated with pre-disposing factors: trauma, certain foods, menstruation, vitamin deficiencies, systemic diseases, smoking cessation, medications and stress.
- They are thought to be caused by an immune response.
Factors
- Both genetics and immunologic factors play a role in the development of aphthous ulcers.
- The exact cause of aphthous ulcers is unknown.
Treatment
- There is no cure for aphthous ulcers.
- Treatment focuses on relieving pain and promoting healing.
- Topical medications, such as corticosteroid creams or gels, can be used to reduce inflammation and pain.
- Pain relievers, such as ibuprofen or acetaminophen, can also be helpful.
- In some cases, a doctor may prescribe a systemic medication, such as a corticosteroid or an immunosuppressant, to help control recurrent aphthous ulcers.
