Lichen Planus in the Oral Cavity: Recognition and Treatment
Table of Contents
Estimated reading time: 9 minutes
Lichen Planus (LP) is a chronic inflammatory condition that can affect various parts of the body, including the skin, mucous membranes, and nails. One of its more troublesome manifestations occurs in the oral cavity, where it presents as oral lichen planus (OLP). OLP is often a painful condition, making it difficult for individuals to eat, drink, or maintain proper oral hygiene (Seo & Lim, 2021). This article explores how to recognize OLP, the underlying factors contributing to its onset, and the treatment approaches available, with a focus on Ayurvedic principles that promote long-term health (Mishra et al., 2020).
Lichen Planus in the Oral Cavity
Recognizing Oral Lichen Planus
Oral lichen planus can manifest in a variety of forms, some more symptomatic than others. Recognizing these manifestations early is essential for effective management and to avoid further complications (Shah & Clark, 2020).
Common Forms of OLP:
Reticular Form: This is the most common and typically appears as a white, lace-like network of lines (known as Wickham’s striae) on the inner cheeks, gums, or tongue. It is often asymptomatic and might be discovered during routine dental checkups (Robinson et al., 2020).
Erosive Form: In this form, the mucosa becomes red, eroded, and painful. This can make eating, drinking, and oral hygiene difficult, significantly affecting quality of life (Shah & Clark, 2020).
Atrophic Form: Atrophic OLP is marked by widespread redness and thinning of the oral mucosa, which can lead to extreme sensitivity, especially to hot, acidic, or spicy foods (Seo & Lim, 2021).
Bullous Form: This is the least common form, characterized by the formation of blisters in the oral cavity. The blisters eventually rupture, leading to painful sores (Robinson et al., 2020).
Symptoms of OLP:
Burning or stinging sensation in the mouth
Sensitivity to spicy, acidic, or hot foods
White patches or lace-like lines on the inner cheeks, gums, or tongue
Red, swollen, and inflamed patches in the oral cavity
Open sores or ulcers that are slow to heal
Difficulty eating, drinking, or speaking due to oral discomfort
Causes and Contributing Factors
The exact cause of oral lichen planus is still not fully understood, but it is generally considered to be an autoimmune disorder. This means the body’s immune system mistakenly attacks healthy cells in the oral mucosa, leading to inflammation and tissue damage (Seo & Lim, 2021). Several factors can trigger or worsen OLP:
Autoimmune Dysfunction: As with other forms of lichen planus, immune dysregulation plays a central role. The immune system targets the mucous membranes, resulting in chronic inflammation and tissue damage (Robinson et al., 2020).
Stress and Psychological Factors: Stress is a well-known trigger for many autoimmune and inflammatory conditions, including OLP. Emotional stress can exacerbate symptoms, making stress management a critical part of any treatment plan (Mishra et al., 2020).
Genetic Predisposition: There may be a hereditary component, with some individuals being more prone to developing OLP due to their genetic makeup (Sharma & Chandola, 2011).
Allergic Reactions: Some cases of OLP may be triggered by allergens, particularly to dental materials such as amalgam fillings, medications, or certain foods (Shah & Clark, 2020).
Hepatitis C and Other Infections: There is some evidence that links oral lichen planus with infections such as hepatitis C, which may contribute to its onset in certain individuals (Seo & Lim, 2021).
Conventional Treatment Approaches
Treatment for oral lichen planus is primarily aimed at managing symptoms, reducing inflammation, and preventing further complications. However, there is currently no cure for OLP, and management often involves a combination of therapies (Robinson et al., 2020).
1. Topical Corticosteroids
Topical corticosteroids are the first-line treatment for managing inflammation and pain in OLP. They are usually applied directly to the affected areas in the form of a gel, ointment, or mouth rinse. While corticosteroids are effective in reducing inflammation, long-term use can lead to side effects such as thinning of the oral mucosa and increased risk of infections (Shah & Clark, 2020).
2. Systemic Medications
For severe cases that do not respond to topical treatments, systemic medications like immunosuppressants or oral corticosteroids may be prescribed. These drugs work by dampening the immune system’s response, thereby reducing inflammation. However, systemic medications come with a higher risk of side effects, including increased susceptibility to infections and long-term health risks (Seo & Lim, 2021).
3. Oral Hygiene Maintenance
Proper oral hygiene is crucial in managing OLP and preventing secondary infections. Patients are advised to use non-irritating, alcohol-free mouthwashes and to brush gently with soft-bristled toothbrushes to avoid aggravating the mucosa (Shah & Clark, 2020).
4. Elimination of Triggers
Identifying and eliminating potential triggers, such as allergenic foods or specific dental materials, can help reduce flare-ups. Dietary adjustments may also be necessary to avoid foods that exacerbate symptoms (Robinson et al., 2020).
Ayurvedic Approach to Oral Lichen Planus
In Ayurveda, oral lichen planus is considered a manifestation of imbalances in the Pitta and Vata doshas, which govern the body’s heat and movement, respectively (Lad, 2012). Imbalances in these doshas can lead to inflammation, dryness, and discomfort in the mucous membranes. Ayurvedic treatment for OLP focuses on balancing the doshas, supporting the body’s natural healing processes, and addressing the root cause of the condition (Mishra et al., 2020).
1. Addressing the Root Cause
Ayurveda takes a holistic approach by assessing the individual’s Prakriti (constitutional type) and Vikruti (current imbalance). OLP is often linked to an excess of Pitta, which governs heat and inflammation. Treatment focuses on pacifying Pitta through diet, lifestyle modifications, and personalized care, emphasizing cooling and soothing measures (Sharma & Chandola, 2011).
2. Immune Modulation and Inflammation Reduction
Rather than suppressing the immune response, Ayurveda aims to modulate it by supporting the body’s natural defenses. This involves balancing Pitta and calming the excessive immune response that contributes to the chronic inflammation seen in OLP (Jaiswal & Williams, 2017). Long-term modulation helps prevent recurrences by addressing the systemic issues driving the condition (Mishra et al., 2020).
3. Dietary Modifications
Diet plays a significant role in managing autoimmune and inflammatory conditions in Ayurveda. Pitta-pacifying foods such as cooling vegetables, fruits, and mild spices are recommended, while foods that aggravate Pitta—such as spicy, sour, and acidic foods—should be minimized (Lad, 2012). This approach helps soothe the mucous membranes and reduces the risk of flare-ups (Sharma & Chandola, 2011).
4. Stress Management
Stress is a known trigger for autoimmune conditions, including OLP. Ayurveda emphasizes the importance of mental well-being in managing chronic conditions, recommending practices such as yoga, meditation, and pranayama (breathing exercises) to manage stress and improve overall health (Jaiswal & Williams, 2017). Regular stress management not only prevents flare-ups but also supports long-term healing (Mishra et al., 2020).
Conclusion
Oral Lichen Planus is a chronic, autoimmune condition that significantly affects oral health and quality of life. Recognizing the symptoms early and adopting a holistic approach to treatment, which includes both conventional and Ayurvedic strategies, can improve outcomes and prevent complications (Sharma & Chandola, 2011). By addressing the root causes of the condition and promoting long-term immune modulation, Ayurveda provides a comprehensive framework for managing OLP, focusing on balancing the body’s internal systems and supporting overall well-being (Lad, 2012).
