Core Tip

Core Tip: Salivary biomarkers, such as interleukin-6, interleukin-8, microRNAs, and DNA methylation patterns, have emerged as non-invasive tools for the early detection of oral squamous cell carcinoma. This review highlights recent advancements in salivary biomarker research, focusing on their diagnostic potential and the integration of cutting-edge technologies, including mass spectrometry and nanobiosensors. By addressing current challenges like assay standardization and saliva variability, this study underscores the transformative potential of salivary diagnostics in improving early oral squamous cell carcinoma detection and patient outcomes.
