Recurrent Aphthous Stomatitis

Recurrent Aphthous Stomatitis (RAS) is a common inflammatory condition of the oral mucosa (the soft tissue lining of the mouth) characterized by recurrent and painful ulcerations.

Here are the main definitions of RAS:

  1. Recurrent: Refers to the repeated and frequent outbreaks of the condition over a period of time.
  2. Aphthous: A term used to describe small, painful ulcers that occur inside the mouth.
  3. Stomatitis: Refers to inflammation of the mouth and oral mucosa.
  4. Ulcerations: Refers to open sores or wounds that are slow to heal.
  5. Painful: Refers to the discomfort or pain associated with the ulcerations.
  6. Inflammatory: Refers to the redness, swelling, and pain caused by the immune system’s response to infection or injury.


The exact cause of RAS is unknown, but several factors have been identified that may contribute to its development. These include:

  1. Genetics: RAS is often seen in families and is believed to have a genetic component.
  2. Immune system: RAS may be caused by an abnormal response of the immune system to certain triggers.
  3. Vitamin and mineral deficiencies: Lack of certain vitamins and minerals, such as iron, vitamin B12, and folic acid, can contribute to the development of RAS.
  4. Stress: Stress is a common trigger for RAS and can make the condition worse.
  5. Hormonal changes: Hormonal changes, such as those during menstrual cycles or pregnancy, can trigger RAS.
  6. Infections: Certain infections, such as viral infections, can trigger RAS.
  7. Food sensitivities: Certain foods, such as chocolate, coffee, and spicy foods, can trigger RAS in some people.
  8. Medications: Certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) and antibiotics, can cause RAS as a side effect.
  9. Smoking: Smoking can increase the risk of developing RAS and make it more difficult to treat.

In conclusion, the main causes of recurrent aphthous stomatitis are not fully understood, but a combination of the genetic, immune system and environmental factors may contribute to its development.


Recurrent Aphthous Stomatitis (RAS), also known as canker sores, is a common condition characterized by the recurring appearance of painful ulcers in the mouth. The main symptoms of RAS are:

  1. Painful ulcers: RAS manifests as shallow, round, or oval-shaped ulcers in the mouth, usually on the inner cheeks, lips, tongue, or gums. The ulcers are often red, surrounded by a yellowish halo, and can cause significant pain and discomfort.
  2. Burning and tingling sensation: Before the appearance of the ulcers, some people may experience a burning or tingling sensation in the affected area.
  3. Swelling: The ulcers may cause swelling and tenderness in the surrounding area.
  4. Difficulty eating and speaking: The painful ulcers can make it difficult to eat, drink, and speak.
  5. Recurring outbreaks: The most significant symptom of RAS is its recurring nature. People with this condition often experience periodic outbreaks of ulcers, which can last for a few days to several weeks.
  6. No fever: Unlike other mouth conditions, RAS does not typically cause a fever or other systemic symptoms.

It is important to seek medical attention if the ulcers are causing significant pain, difficulty eating and speaking, or if they persist for more than two weeks.


  1. Clinical Examination: A thorough physical examination of the mouth, including the tongue, gums, and inside of the cheeks, can help identify any ulcers or sores that may be indicative of recurrent aphthous stomatitis.
  2. Biopsy: In some cases, a biopsy of the affected area may be necessary to confirm the diagnosis. This involves taking a small sample of the tissue for laboratory analysis to determine the underlying cause of the ulcers.
  3. Blood Tests: Blood tests may be ordered to rule out any underlying medical conditions that could be contributing to the development of recurrent aphthous stomatitis, such as anemia or a weakened immune system.
  4. Mouth Rinse Samples: A sample of saliva or other fluids from the mouth may be collected and tested to determine the presence of any infections or bacteria that may be contributing to the formation of ulcers.
  5. Allergic Testing: Allergic testing may be performed to determine if any particular substances or allergens may be triggering the formation of ulcers in some individuals.
  6. Imaging Tests: Imaging tests, such as X-rays or magnetic resonance imaging (MRI), may be used to evaluate the structure and function of the mouth and to identify any abnormalities that may be contributing to the development of recurrent aphthous stomatitis.

It is important to note that a definitive diagnosis of recurrent aphthous stomatitis may not always be possible and that a combination of tests and a thorough medical history may be necessary to make a diagnosis.


The main treatment options for RAS include:

  1. Topical Anesthetics: Over-the-counter topical anesthetics such as benzocaine, or lidocaine can be used to relieve the pain associated with RAS.
  2. Corticosteroids: Corticosteroids such as prednisone, can be prescribed to reduce inflammation and swelling in the mouth.
  3. Antibiotics: In some cases, antibiotics such as tetracycline, can be prescribed to help reduce the frequency of RAS outbreaks.
  4. Vitamin and mineral supplementation: Vitamin and mineral supplementation, such as folic acid and iron, can help improve the health of the mouth and reduce the frequency of RAS outbreaks.
  5. Avoiding triggers: Triggers such as stress, food allergies, and certain medications can cause RAS outbreaks. Avoiding these triggers can help reduce the frequency of RAS outbreaks.
  6. Mouthwash and Rinses: Mouthwash and rinses containing chlorhexidine or saltwater can help cleanse the mouth and reduce the risk of RAS outbreaks.
  7. Pain Management: Over-the-counter pain relievers such as ibuprofen or acetaminophen can be used to relieve the pain associated with RAS.

It is important to note that the treatment of RAS may vary depending on the severity and frequency of outbreaks. It is important to consult with a healthcare provider for an individualized treatment plan.
