Regeneration of tissues of the oral complex: current clinical trends and research advances

Abstract

Regenerative therapy in oral health care is limited by both the body's natural capacity for regeneration and the materials and methods currently available. Research on various aspects of regenerative therapy, such as tissue engineering and stem cell and gene therapy, has produced promising results. Compelling advances, ranging from the discovery and characterization of stem cell populations in oral tissue to the engineering and transplantation of whole tooth structures, could result in exciting new treatment methods for clinicians in the near future. In this review, we discuss the limitations of natural healing and regeneration of various tissues of the oral complex, including teeth, periodontium and salivary glands, and summarize current treatment methods for tissue damage as well as research advances in oral tissue regeneration.
