Leukoplakia is marked by the formation of white or gray thickened patches on mucous membranes of cheeks, gums or tongue. The cause for Leukoplakia is still not known. However, it is mainly linked to usage of tobacco and consumption of alcohol. Hairy kind of Leukoplakia is observed during HIV infection which is caused by Epstein-Barr virus. Leukoplakia in long run may lead to oral cancer. Hence, oral examination with the dentist is advisable when the condition is suspected. Dentists send the tissue for biopsy to rule out the possibility of oral cancer. If a biopsy comes back positive for oral cancer, the patch must be removed immediately. This can help prevent its spread.
In a study to register the prevalence of oral mucosal lesions in an adult and child population in selected regions in Norway, Prevalence of Leukoplakia was observed to be 0.45% in adults >18 years. Minimum surgical trauma, good hemostasis, lack of intraoperative complications, fast purification of mucous in urinary bladder from a crust and short period of postoperative after treatment are the main advantages of laser ablation of leukoplakia of urinary bladder.
