Focus on Methodology: Salivary bioscience and research on adolescence: An integrated perspective

The characterization of the salivary proteome and advances in biotechnology create an opportunity for developmental scientists to measure multi-level components of biological systems in oral fluids and identify relationships with developmental processes and behavioral and social forces. The implications for developmental science are profound because from a single oral fluid specimen, information can be obtained about a broad array of biological systems and the genetic polymorphisms related to their function. The purpose of this review is to provide a conceptual and tactical roadmap for investigators interested in integrating these measurement tools into research on adolescent health and development.
