Abstract:
The concept of homeostatic medicine has helped the researchers to understand the periodontal tissues in a completely new dimension. Periodontal tissues are subjected to complex external environmental stimuli and the internal tissues are continuously undergoing active remodeling. Periodontal regional immunity is continuously activated by local stimuli and interacts with the epithelial barrier, stromal tissue/extracellular matrix, and bone-coupled systems in a complex manner. Together, this complex network shapes the periodontal homeostasis. Under physiological conditions, moderate regional immunity relies on barrier function, intrinsic immune cells to control periodontal microbiota and maintain homeostasis. Under pathological conditions, pathogenic microbiota drive the periodontal homeostasis imbalance through over-activated regional immunity such as neutrophils, helper T (Th) 17 cells and B cells, causing periodontitis. Using the most basic immunological classification as a framework, this paper provides a systematic overview of the above mechanisms by which regional immunity regulates periodontal homeostasis, reviews the translational studies that have been carried out on homeostatic remodeling strategies targeting regional immunity, and proposes a series of periodontal homeostasis medicine research directions worth exploring, as well as potential new targets and strategies for homeostatic remodeling.
