Regenerative endodontics have gained much attention in the past decade because it offers an alternative approach in treating endodontically involved teeth. Instead of filling the canal space with artificial materials, it attempts to fill the canal with vital tissues. Regeneration is to regain the tissue and its function to the original state. In terms of pulp regeneration, a clinical protocol that intends to re-establish pulp/dentin tissues in the canal space has been developed, termed revitalization or revascularization. Histological studies from animal and human teeth receiving revitalization have shown that pulp regeneration is difficult to achieve. In tissue engineering, there are two approaches to regeneration tissues: cell-based and cell-free. The former involves transplanting exogenous cells into the host and the latter does not. Revitalization belongs to the latter approach. A number of crucial concepts have not been well discussed, noted or understood in the field of regenerative endodontics when dealing with pulp/dentin regeneration: i) critical size defect of dentin and pulp; ii) cell lineage commitment to odontoblasts; iii) regeneration vs repair; and iv) hurdles of cell-based pulp regeneration for clinical applications. This review article will elaborate and analyze at cellular and molecular levels these missing concepts and some of which will explain why the non-cell-based revitalization procedure is difficult to establish pulp/dentin regeneration. Although cell-based approach has been proven to regenerate pulp/dentin, such an approach will face barriers. The key hurdle being the shortage of the current good manufacturing practice (cGMP) facilities which is discussed herein.
Considerable excitement exists for developing dental applications that employ post-natal stem cells and concepts of tissue engineering. Although much remains to be done to advance this field, progress has been made in clinical regenerative endodontic procedures: literally, saving teeth by regenerating a functional pulp-dentin complex. This program will describe the current status of regenerative endodontic procedures, their potential and predictors of healing success. Both clinical and basic studies will be reviewed to provide the practitioner with the latest information on this field with an emphasis on practical steps to apply these procedures in treating selected patients.
