Periodontal regeneration is considered to be biologically possible but clinically unpredictable. In periodontitis, inflammation manifests clinically as loss of supporting periodontal tissues and regeneration of damaged tissue is the main goal of treatment. For decades, periodontists have sought to repair the damage through a variety of surgical procedures, and use of grafting materials and growth factors, and of barrier membranes. Reports have emerged that demonstrate which populations of adult stem cells reside in the periodontal ligaments of humans and other animals. This opens the way for new cell-based therapies for periodontal regeneration. This review provides an overview of adult human stem cells and their potential use in periodontal regeneration.
