Salivary metagenome of OPMDs
Unstimulated saliva from healthy controls (n = 17), oral lichen planus (OLP; n = 15), proliferative verrucous leukoplakia (PVL; n = 8), and solitary oral epithelial dysplasia (n = 17) was analyzed by shotgun metagenomic sequencing, with oral squamous cell carcinoma (OSCC; n = 4) included as a malignant reference group.
