Dear Colleagues,

Saliva contains numerous enzymes, hormones and antibodies, which reflect their blood serum composition. Saliva is collected non-invasively, eliminating the stress that often accompanies patients during routine blood collection. In contrast to blood drawing, collecting saliva is safe and easy, even for less qualified medical personnel.

Saliva, as a diagnostic material, has so far been used mainly to monitor oral diseases (caries or periodontitis). Its is now increasingly being used to monitor systemic health. Currently, studies of saliva as an alternative to blood and urine in medical diagnostics, has focused on detecting various biomarkers (proteins, nucleic acids, metabolites etc.) that may become potential prognostic indicators for the diagnosis and treatment of selected systemic diseases. Saliva could have a wide range of diagnostic applications in many fields of medicine, such as gastroenterology, endocrinology, cardiology and oncology.

In this Special Issue, we invite you to submit your high-quality papers (original articles, systematic reviews) focusing on non-invasive salivary diagnostics in both oral and systemic diseases.
