Oral lichen planus is one of the most common diseases in oral mucosa, and many patients are very concerned about the etiology, treatment, and prognosis of this disease. The answers to several questions most often asked by patients in clinical practice are now collated for your reference. 1, oral lichen planus is what happened? Oral lichen planus is a chronic inflammatory disease that occurs in the oral mucosa, is a common disease, its incidence is about 1 to 2%. The disease is usually manifested as white reticular stripes that occur in the oral mucosa for a long time, and can be accompanied by congestion and erosion when serious, the first symptom that patients feel is often the irritating pain of the oral mucosa when eating spicy and hot food, or the rough discomfort of the oral mucosa, such as the above symptoms, should be promptly to the oral mucosal disease specialist. 2.How is oral lichen planus caused? The specific causes and pathogenesis of oral lichen planus are not yet completely clear, and the more recognized view is that its onset is closely related to the local and systemic immune dysfunction of the lesion, in addition, mental factors (such as anxiety, depression, irritability, etc.), infection factors, local irritation factors, endocrine factors, genetic factors, systemic systemic diseases, etc. all have different degrees of influence on its onset. 3, what is the relationship between oral lichen planus and mental factors? Research shows that the onset of oral lichen planus has a close relationship with mental factors, about 50% of patients with oral lichen planus have a history of mental trauma, life and work pressure, spiritual life and other factors that lead to mood disorders and anxiety. These bad psychological state can lead to the body’s immune function disorder, prompted the onset of oral lichen planus, repeated aggravation, and delayed. 4, oral lichen planus can cure the root? Oral lichen planus is a chronic disease, and the cause is unknown, so there is no cure. But through life conditioning, regular treatment and regular review, most patients can get good control of the disease. The so-called good control refers to the elimination or reduction of the congestion and erosion of the oral mucosa, the relief of pain and roughness when eating and the prevention of the expansion of the lesion and the aggravation of the disease. 5.Will oral lichen planus become cancerous? Many patients are more concerned about this issue, through consulting websites or consulting dentists, we will learn that oral lichen planus is a precancerous lesion, so we feel very nervous. In fact, the tendency of oral lichen planus to become cancerous has always been a controversial issue in academic circles. Therefore, for the majority of patients, there is no need to be overly alarmed about the carcinogenesis of oral lichen planus. However, in other words, almost all of the cancerous cases we observed in the clinic occurred without regular treatment and regular review, especially when the congested lesions were not well controlled. Therefore, in order to prevent the occurrence of cancer to the greatest extent, regular treatment and regular review of the disease is very necessary to achieve the purpose of “early detection, early diagnosis and early treatment”. 6.What should I do if I have oral lichen planus? When you suspect or are told by other doctors that you are suffering from oral lichen planus, patients should go to the oral mucosal disease specialist for a clear diagnosis. If the diagnosis is confirmed, the oral mucosal disease specialist will classify the disease according to the patient’s specific situation, formulate individualized treatment plan for standardized treatment, and arrange a review time. Patients should not purchase their own medication before the condition is clear, especially without the use of large amounts of antibiotics (anti-inflammatory drugs) or vitamins. In terms of life, patients should pay attention to maintaining good oral hygiene, a regular work and rest schedule, an optimistic and cheerful mood, a light and nutritious diet, and avoiding tobacco, alcohol and spicy stimulating foods. In addition, patients are advised to follow the doctor’s instructions for regular review in order to observe changes in their condition.
