What are the common factors causing oral leukoplakia? Leukoplakia refers to the plaque damage of white or gray keratinizing lesions only occurring on the mucosa, which is very harmful to the oral cavity. So what are the common factors causing oral leukoplakia?
This kind of plaque on oral mucosa can't be wiped off, and can't be classified into other diseases in clinic and histopathology. It is a common non infectious chronic disease. Mucous membrane can occur in all parts of oral cavity, but most of them are buccal and lingual. In 1980, the prevalence rate was 10.47% (including smoke spots). For a long time, the white plaque on the oral mucosa has been called "white spot", which makes many white lesions mixed with white spot, resulting in inappropriate results in epidemiology and treatment. In addition to white, the color of white spots can also show the damage of red and white. It should be clear that leukoplakia is a clinical term seen by naked eyes, and the histopathological changes should be consistent with the characteristics of precancerous lesions - epithelial dysplasia, rather than simple epithelial hyperplasia.
Local stimulating factors play an important role in the pathogenesis of leukoplakia. Smoking is the common cause. 80% - 90% of patients with leukoplakia have smoking habits, and the location of the disease is consistent with the stimulating location of smoking. Other stimulation such as chewing betel nut, wine, vinegar, spicy, hot, bad prosthesis, residual crown, residual root can also cause leukoplakia. Among the systemic factors, Candida albicans infection, iron deficiency anemia, vitamin B12 and folic acid deficiency, syphilis, radiation and xerostomia are closely related to leukoplakia. The number of middle-aged and elderly patients was more than that of female patients (male ∶ female = 13.5 ∶ 1).
After reading the above content, we should have some understanding of the common factors causing oral leukoplakia. Today, we will introduce the common factors causing oral leukoplakia. More topics about oral health will continue to be introduced in the following articles. Welcome to check. Wish you a happy life!
