When it comes to “oral white spots”, people often look at the text and think that it is a white plaque that occurs on the oral mucosa. In fact, this understanding is one-sided. There are many lesions that may appear as white patches on the oral mucosa, such as candidiasis albicans, oral lichen planus, discoid lupus erythematosus, benign hyperkeratosis, white edema, wandering tongue, vitiligo, etc. The medical term “oral leukoplakia” refers specifically to “oral leukoplakia”, which is a “precancerous lesion” that patients must be highly alert to! Its oral characteristics are: creamy white raised plaque, rough or slightly rough surface, some ulcers or erosions occur on the basis of the plaque, some plaque surface is burr-like or fluffy, some are mixed with white particles in the middle of the congested and red “background”. Patients have a rough, woody, astringent feeling. Based on these characteristics, the clinician can make a preliminary diagnosis of “oral leukoplakia” through careful examination, which can be confirmed by pathological biopsy before a final diagnosis is made. The danger of leukoplakia is that it is not painful, not itchy, and not ulcerated, so it is often difficult for patients to detect. Since oral leukoplakia is a precancerous lesion, it is likely to become cancerous if it is left to develop. Academics around the world report that the cancer rate of this disease ranges from 10% to 30%. The following conditions have a high tendency to become cancerous: 1. Elderly patients over 60 years old. 2.Although the prevalence rate of men is significantly higher than that of women, non-smoking women, especially young leukoplakia patients, have a high possibility of malignant transformation. 3, The longer the smoking time and the greater the possibility of high smoke volume. 4.White spots located on the edge of the tongue, tongue belly, floor of the mouth and the corner of the mouth are prone to malignant transformation. 5.The surface is rough, with ulcers or erosions are prone to malignant transformation. 6, pathology with abnormal epithelial hyperplasia, the more serious the degree, the more likely to malignant. 7. Those who suffer from Candida albicans infection. 8. Those who have lesions for a longer period of time. 9, with irritation pain or spontaneous pain. Specially remind those who have oral white damage, they must go to the hospital to ask the dentist to take a look and determine whether it is oral white spot. If you already suffer from oral white spots, you should receive proper treatment. If accompanied with the above conditions, you should be more vigilant and insist on regular follow-up. Do not take oral white spots lightly!
