Fabrication of a multifunctional hydrogel with a robust interface bioinspired by the structure of the dentogingival junction.

The dentogingival junction with a perforating fiber structure is an anatomical and functional interface between the gingiva and tooth structure. Inspired by this structure, this study involves the development of a handy method to fabricate a multifunctional hydrogel with a robust interface, which is also universal for preparing diverse materials that require a Janus structure.
