Salivary bacterial shifts in oral leukoplakia resemble the dysbiotic oral cancer bacteriome [PDF]

Journal of Oral Microbiology, 2021
Objective: While some oral carcinomas appear to arise de novo, others develop within long-standing conditions of the oral cavity that have malignant potential, now known as oral potentially malignant disorders (OPMDs). The oral bacteriome associated with

Study of Caspase 8 mutation in oral cancer and adjacent precancer tissues and implication in progression.

PLoS ONE, 2020
It is hypothesized that same driver gene mutations should be present in both oral leukoplakia and cancer tissues. So, we attempted to find out mutations at one of the driver genes, CASP8, in cancer and adjacent leukoplakia tissues.

Oral leukoplakia: Transmission electron microscopic correlation with clinical types and light microscopy

Dental Research Journal, 2012
Background: Leukoplakia, is a precancerous lesion that is most commonly encountered in the oral cavity. The grade of dysplasia is presumed to be the most important indicator of malignant potential. There are many promising aspects in advanced methods for

Prevalence of oral leukoplakia

Medicinski pregled, 2003
Introduction This paper reviews epidemiologic studies on prevalence of oral leukoplakia. Special emphasis is placed on population selection, diagnostic criteria, type and training of examiners and risk factor assessment. Prevalence of leukoplakia in these studies has ranged from 0.6% to 4.6%.
