Abstract

Human population is facing a revolutionary change in the demographic structure with an increasing number of elderly people requiring an unmet need to ensure a smooth aging process and dental care is certainly an important aspect that has to be considered. To date, dentistry has been conservative and the need of transferring the scientific models of regenerative dentistry into clinical practice is becoming a necessity. The aim of this study was to characterize the differentiation commitment (in vitro) and the clinical grafting ability (in vivo) of a population of progenitor stem cells obtained after mechanical digestion of dental pulp with an innovative system recently developed. This approach was successfully used in previous studies to obtain a clinical-grade ready to use dental pulp fragments that could be grafted in autologous tissues to obtain bone. We are thus showing that micro grafts resulting from mechanical digestion contain stem cells with a mesenchymal phenotype, able to differentiate toward different cell types and to generate new bone in patients. We are providing data for the establishment of standardized and routinely oral surgery approaches, having outlined the cellular properties of human stem cells obtained from the dental pulp. This method can represent a valid tool for both regenerative medicine and tissue engineering purposes not only applicable to the cranio-maxillofacial region but, likely, to different bone pathologies for a fastening and healing recovering of patients.
