Topic title: Development and application of regenerative materials adapted to extreme periodontal environments

Abstract:

Periodontitis is not only the most prevalent infectious disease but also a risk factor for various chronic illnesses. Due to the rich blood supply in the maxillofacial region and the open oral environment, challenges exist in maintaining dryness, sterility, and promoting regeneration in periodontal tissue regeneration. Our  team has discovered that the mucous secreted by the Andrias davidianus when stimulated，which have wet adhesion, antibacterial, hemostatic, and regenerative capabilities. Therefore, we have utilized the skin extraction of A. davidianus, named as SSAD, to develop bio-materials that promote the regeneration of both soft and hard tissues.
