This book provides evidence-based information in the field of regenerative dentistry discussing the most recent advances, current clinical applications, limitations and future directions. The coverage encompasses the regeneration of alveolar bone, the dentine-pulp complex, enamel, the periodontium and other tissues associated with the oral cavity. A full description is provided of regenerative approaches in dentistry including regenerative endodontics and tooth repair, regenerative periodontics, regenerative assisted orthodontics, regenerative approaches in oral medicine, and dental tissue derived stem cells and their potential applications. The book is written by an international team of leading experts. It will be beneficial for students, practitioners and researchers in the fields of endodontics, periodontics and implantology.
