The diagnosis of oral leukoplakia is primarily made using the following methods: 1. Clinical observation: Patients typically present with white patches, spots, or ulcers on the oral mucosa, which may be accompanied by pain, roughness, numbness, or a gritty sensation. These symptoms can affect the patient's daily life and eating habits. 2. Autofluorescence examination: Specialized instruments are used to photograph the affected area and assess for any loss of autofluorescence, providing a preliminary confirmation of oral leukoplakia. 3. Exfoliative cytology: Cells are scraped from the lesion site and examined specifically to confirm the condition and determine whether malignant transformation has occurred. 4. Toluidine blue staining: An appropriate concentration of toluidine blue solution is applied to the affected area and then rinsed with acetic acid. If the stained area remains deep blue, oral leukoplakia may be present. 5. Histopathological examination: For suspected cases, a histopathological analysis can be performed to further confirm the diagnosis. If you experience any related symptoms, it is recommended to seek timely medical evaluation and treatment.
