Tissue engineering combines the principles of materials and cell transplantation to develop, substitute tissues, and/or promote endogenous regeneration. Tissue engineering involves the use of a tissue scaffold for the formation of new viable tissue for a medical purpose. Tissue engineering is an important field of regenerative medicine for tissue repair. Tissue engineering covers a broad range of applications, in practice, the term is closely associated with applications that repair or replace portions of whole tissues (i.e., bone, cartilage, blood vessels, bladder, skin, muscle, etc.).

This interdisciplinary engineering has attracted much attention as a new therapeutic means that may overcome the drawbacks involved in the current artificial organs and organ transplantation that have been also aimed at replacing lost or severely damaged tissues or organs. However, the tissues regenerated by this tissue engineering and widely applied to patients are still very limited. This includes skin, bone, cartilage, capillary, and periodontal tissues.

The aim of this Special Issue is to highlight research regarding traditional and herbal medicine in oral tissue engineering. Submissions should include medicine related to natural materials such as scaffolds, plant substances that stimulate stem cell differentiation as natural growth factors in regenerative medicine. We welcome original research articles (in vitro and in vivo) and review articles in traditional and herbal medicine in oral tissue engineering and regenerative medicine.

Potential topics include but are not limited to the following:

• Traditional medicine in oral tissue engineering
• Herbal drugs for oral stem cell/ cell differentiation
• Natural and bioactive materials
• Natural and biomaterial in craniofacial tissue engineering (in vitro, in vivo, clinical studies)
• Natural and biomaterial in dental tissue engineering (in vitro, in vivo, clinical studies)
