Saliva: A Miraculous Biofluid for Early Detection of Disease

Abstract

Saliva, a multi constituent oral fluid has high potential for the surveillance of general health and disease. To reach the above goal through saliva based diagnostics, two requisites must be fulfilled as discovering biomarker for different diseases among the complicated components of saliva and advancing sensitivity and specificity of biomarkers through persistent development of technologies with collective efforts over several years. Saliva has been demonstrated to be a promising bodily fluid for early diagnosis of disease and salivary diagnostics has exhibited tremendous potential in clinical applications. This review presents an impression of the value of saliva as a credible diagnostic tool, the innovation of salivary biomarkers and development of salivary diagnostics in the future.
