Microbial dysbiosis and tumor biomarker expression in oral leukoplakia and oral squamous cell carcinoma: A quantitative polymerase chain reaction-based immunohistochemical study.
Porphyromonas gingivalis is a major periodontal pathogen increasingly associated with oral leukoplakia (OL) and oral squamous cell carcinoma (OSCC) due to its role in microbial dysbiosis and carcinogenesis. This study aimed to evaluate the relative abundance of P. gingivalis in healthy controls, OL, and OSCC patients a...
