Salivary diagnostics is a rapidly developing field using nanotechnology and molecular diagnostics to helporal & systemic diseases. The term Salivaomics was coined in 2008 and includes study of genomics, transcriptomics, proteomics, metabonomics and microRNA (miRNA) analysis in saliva. Due to quick advancement in saliva omics, saliva is well documented as a pool of biological markers. Saliva is a non-invasive and safe source, which can be an alternative for blood in the diagnosis and prognosis of diseases. This review summarises various salivary tests used for diagnosis of oral & systemic diseases by detecting their specific biomarkers.
