Oral Lichen Planus

Oral lichen planus (OLP) is a chronic inflammatory condition that affects the mucous membranes inside the mouth. It is characterized by the presence of white, lacy patches or lesions on the tongue, cheeks, gums, and other areas of the oral cavity.

Causes and Risk Factors

The exact cause of OLP is not fully understood, but it is believed to be an autoimmune disorder, where the immune system mistakenly attacks healthy cells in the mouth. Certain factors may trigger or exacerbate the condition, including:

• Hepatitis C infection
• Other viral infections, such as human papillomavirus (HPV)
• Allergic reactions to dental materials, such as mercury or gold
• Stress and anxiety
• Hormonal changes
• Genetic predisposition

Symptoms

The symptoms of OLP can vary in severity and may include:

• White, lacy patches or lesions on the tongue, cheeks, gums, and other areas of the oral cavity
• Redness and inflammation of the affected areas
• Pain or discomfort, especially when eating spicy or acidic foods
• Burning sensation in the mouth
• Dryness of the mouth
• Difficulty swallowing or speaking

Diagnosis

OLP is typically diagnosed based on a combination of clinical examination, medical history, and laboratory tests. The diagnosis may involve:

• Visual examination of the oral cavity to identify characteristic lesions
• Biopsy of affected tissue to rule out other conditions, such as oral cancer
• Blood tests to check for underlying infections or autoimmune disorders
• Review of medical history to identify potential triggers or contributing factors

Treatment and Management

Treatment for OLP typically focuses on managing symptoms and reducing inflammation. This may involve:

• Topical corticosteroids to reduce inflammation and suppress the immune system
• Antihistamines or pain relievers to manage discomfort and itching
• Antifungal medications to treat secondary infections
• Lifestyle modifications, such as avoiding spicy or acidic foods, practicing good oral hygiene, and managing stress
• Surgery or laser therapy to remove lesions or promote healing in severe cases

Prognosis and Complications

OLP is a chronic condition, and while treatment can help manage symptoms, it may not completely eliminate the disease. Potential complications of OLP include:

• Increased risk of oral cancer, particularly in cases with persistent or severe lesions
• Dental problems, such as tooth decay or gum disease, due to difficulty maintaining good oral hygiene
• Nutritional deficiencies or weight loss due to difficulty eating or swallowing
• Emotional distress or anxiety related to the condition and its impact on quality of life
