The value of salivary biomarkers for diagnostic and prognostic assessments has become increasingly well established in medicine, pharmacology, and dentistry. Certain salivary components mirror the neuro-endocrine status of the organism. Other saliva products are protein in nature, and can serve to reflect immune surveillance processes. The autonomic nervous system regulates the process of salivation, and the concentration of yet other salivary components, such as alpha-amylase, which provide a reliable outcome measure of the sympathetic response. Here, we discuss molecular technologies that have permitted giant steps in the utilization of salivary samples and micro-fluidics for the benefit of diagnostic medicine and dentistry, and their putative role in springing forward research in psychobiology.
