(redirected from oral self-examination)

leukoplakia

 [loo″ko-pla´ke-ah]
a disease marked by the development of white thickened patches on the mucous membranes of the cheeks (leukoplakia buccalis), gums, or tongue (leukoplakia lingualis); the patches sometimes form fissures and often become malignant. They may grow into larger patches or form ulcers. Those in the mouth may in time cause pain during swallowing of food or speaking. Leukoplakia affects mostly middle-aged to elderly men, often after prolonged irritation of the mouth from such varying factors as badly fitting dentures or immoderate use of tobacco.

Treatment is aimed at removing any possible cause of physical or chemical irritation; the patient should give up tobacco and possibly also alcohol and extremely hot food. Dental attention may be necessary if teeth are uneven or dentures do not fit properly. Surgical removal of the affected area is relatively simple and may be the best means of preventing further development of the condition.
oral hairy leukoplakia a white filiform to flat patch occurring on the tongue or, rarely, on the buccal mucosa, caused by infection with Epstein-Barr virus and associated with human immunodeficiency virus infection.
leukoplakia vul´vae the presence of hypertrophic grayish-white infiltrated patches on the vulvar mucosa; specific diagnosis is determined by biopsy.

Despite the lack of studies that prove an association between oral self-examination and a reduction in rates of mortality and fatality due to oral cancer, in one randomized trial, it was found that these rates decrease when there is screening by health professionals trained in identifying suspect lesions for oral cancer, timely confirmation of such suspicions by pathological examinations and follow-up through immediate treatment (14).
