"Salivary Diagnostics" surveys one of the most exciting areas of research in
oral biology. Regarded as the mirror of the body, saliva has immense potential
to yield real clinical improvements in our ability to diagnose, and hence treat,
oral and systemic conditions. The composition of saliva and other oral fluids
reflects the tissue fluid levels of therapeutic, hormonal, and immunological
molecules, as well as the presence of markers for systemic and oral disease.
