Lichenoid amalgam reaction stomatitis is a mouth condition that affects some individuals. It might sound like a complex term but let’s break it down into simpler terms. Think of it as a mouth sore or inflammation that happens due to a reaction from dental fillings, specifically those made from amalgam, a material that often contains mercury.
Lichenoid Amalgam Reaction Stomatitis, often referred to as LARS, is a condition that affects your mouth. In simple terms, it’s an inflammatory response in your mouth that is linked to the presence of amalgam fillings (dental fillings made from a mixture of metals). It’s like an allergy to your dental fillings, but its symptoms are similar to another oral disease called oral lichen planus.
What is Lichenoid Amalgam Reaction Stomatitis?
The name of this condition, Lichenoid Amalgam Reaction Stomatitis, comes from the characteristics it displays:
- Lichenoid: This refers to a type of skin or mucous membrane reaction that resembles lichen, a type of fungus that grows on rocks and trees. In the context of this condition, lichenoid refers to changes in the oral mucosa (the lining of the mouth) that appear similar to lichen.
- Amalgam: Dental amalgam is a common material used in fillings. It’s a mixture of metals, including mercury, silver, tin, and sometimes copper.
- Reaction: This refers to the body’s response to a foreign substance—in this case, the amalgam.
- Stomatitis: This is a general term for an inflammation or soreness of the mouth.
When we put these terms together, Lichenoid Amalgam Reaction Stomatitis refers to a specific type of mouth soreness or inflammation that occurs as a reaction to dental amalgam.
Types of Lichenoid Amalgam Reaction Stomatitis
The two main types of this condition, based on the appearance and location of lesions, are:
- Reticular Form: This type is characterized by white, lace-like patterns on the mucous membranes. The lesions may be slightly raised and can have red, inflamed areas surrounding them. They often occur on the inside of the cheeks, tongue, and gums.
- Erosive Form: In this more severe form, the lesions are painful, red, swollen, and may have open sores. These erosive lesions often occur on the gums or underneath the tongue. They can make eating or drinking a painful experience.
Causes
Despite being uncommon, it’s important to understand its potential causes. Below, we’ll delve into possible triggers or contributing factors that can increase the likelihood of developing lichenoid amalgam reaction stomatitis. These aren’t ranked in any particular order of frequency or significance.
- Type of Amalgam: The material that the dental amalgam is made from can play a significant role. Some people may react to specific metals used in the amalgam.
- Individual Immune Response: Everyone’s immune system is unique, and some people may have a hypersensitive response to dental amalgam.
- Genetic Factors: Genetic predisposition can influence the way a person’s body reacts to foreign substances, including amalgam.
- Allergies: If a person is allergic to metals used in amalgam, this could trigger a reaction.
- Poor Dental Hygiene: Neglected oral health can lead to inflammation, which may exacerbate the reaction to amalgam.
- Age: Older adults might have a higher risk due to lifetime exposure to various allergens, including metals.
- Gender: Women tend to experience autoimmune diseases more often than men, possibly increasing the risk of a lichenoid reaction.
- Existing Autoimmune Diseases: People with autoimmune conditions are more likely to develop other immune-related issues, such as lichenoid reactions.
- Poorly Fitted Amalgam Fillings: Improperly fitted fillings can increase contact and exposure to the amalgam, triggering a reaction.
- Fractured Amalgam Fillings: A broken filling can release more amalgam particles, potentially heightening the body’s immune response.
- Frequency of Dental Procedures: Regular exposure to amalgam due to multiple dental procedures could increase the risk.
- Stress: Emotional or physical stress can exacerbate immune responses, potentially causing a reaction.
- Underlying Oral Diseases: Conditions like gingivitis or periodontitis might make the mouth more susceptible to a lichenoid reaction.
- Dental Infections: Existing oral infections could increase the likelihood of developing stomatitis.
- Use of Certain Medications: Some drugs can cause a hypersensitive reaction in the oral cavity.
- Tobacco Use: Smoking or chewing tobacco can exacerbate the inflammatory response.
- Alcohol Consumption: Alcohol can cause inflammation in the mouth, potentially worsening the reaction.
- Poor Diet: Lack of essential nutrients can weaken the immune system and make the body more prone to reactions.
- Chronic Illnesses: Conditions such as diabetes can affect the body’s immune response.
- Oral Trauma: Injuries in the mouth might expose more tissues to the amalgam, inciting a reaction.
- Environmental Factors: Exposure to specific allergens or toxins in the environment can affect immune responses.
- Heavy Metal Exposure: Exposure to heavy metals other than those in amalgam might enhance the body’s sensitivity.
- Existing Lichen Planus: If a person already has lichen planus, the immune response could be heightened.
- Oral Cancer: In rare cases, lichenoid reactions can be linked to oral cancer.
- Radiation Therapy: Patients undergoing radiation therapy for oral or head and neck cancers may have an increased risk.
- Chemotherapy: Similarly, chemotherapy can alter the body’s immune response, raising the risk of stomatitis.
- Hormonal Changes: Changes in hormone levels, as seen during menopause, could influence immune responses.
- HIV/AIDS: People with HIV/AIDS may be more susceptible due to their compromised immune systems.
- Hepatitis C: There’s a potential link between Hepatitis C and lichenoid reactions.
- Poorly Made Dentures: Dentures that don’t fit well can lead to inflammation and possible lichenoid reactions.
Symptoms

Diagnosis
In LARS, your immune system reacts to the amalgam, leading to lichen-like changes and inflammation in your mouth. The common signs of this condition are white patches, redness, and a burning sensation in the mouth. It can also cause some discomfort while eating or speaking.
Now that we have a basic understanding of what LARS is, let’s dive into the potential diagnoses and tests used to identify and manage this condition. Please remember that this information is meant to guide understanding and is not a substitute for professional medical advice.
Diagnosis and Tests for Lichenoid Amalgam Reaction Stomatitis
1. Medical History: This is a basic but critical step where your dentist or doctor will ask about your symptoms, dental history, and whether you have allergies or other medical conditions.
2. Oral Examination: The healthcare provider will check your mouth for the characteristic white patches and inflammation associated with LARS.
3. Dental X-Rays: These are useful to visualize the extent and condition of your dental fillings, and assess if any of them are leaking or damaged.
4. Allergy Testing (Patch Test): If you’re suspected of having an allergic reaction to amalgam, an allergist might perform a patch test. This involves applying a small amount of amalgam to your skin and observing for signs of an allergic reaction.
5. Biopsy: In some cases, a small sample of tissue from the affected area in your mouth might be taken and examined under a microscope to confirm the diagnosis.
6. Blood Tests: Blood tests are done to rule out other causes of mouth inflammation, such as infections or autoimmune diseases.
7. Salivary Flow Test: This test measures the amount of saliva produced, as dry mouth can exacerbate symptoms of LARS.
8. Oral Candidiasis Test: Candidiasis, a type of yeast infection, can sometimes mimic the symptoms of LARS, so a test may be done to rule this out.
9. Referral to a Specialist: If your condition is complex, you may be referred to a dermatologist or oral medicine specialist for further evaluation.
10. Elimination Diet: In rare cases, you might be asked to follow an elimination diet to rule out food allergies, which can also cause inflammation in the mouth.
11. Immunofluorescence: This test uses fluorescent dyes to highlight certain cells or proteins in a tissue sample, helping to identify immune-related conditions, including LARS.
12. Microscopic Examination of Oral Tissue: This allows doctors to identify the characteristic lichenoid changes in the tissue.
13. Cell Culture: In uncertain cases, cells from your mouth may be grown in a lab to further study and identify the cause of your symptoms.
14. Imaging Tests: Tests like CT scan or MRI can help identify any abnormalities in the mouth or throat that might contribute to your symptoms.
15. Oral Mucosal Indirect Immunofluorescence: This test is similar to immunofluorescence but is done on a specific area of the mouth to identify immune reactions.
16. Sialometry: This test measures the level of salivary gland function, which can be impaired in LARS.
17. Oral Bacterial Culture: This test helps to rule out bacterial infections that may be causing or contributing to your symptoms.
18. Vital Staining: This is a method used to identify cells or tissues under a microscope by using a special dye that makes them easier to see.
19. Examination of Amalgam Fillings: The dentist will closely examine the condition of your amalgam fillings to check for wear and tear or leakage.
20. Replacement of Amalgam Fillings: If it is confirmed that your amalgam fillings are causing LARS, your dentist may recommend replacing them with an alternative material.
