Cell-Based vs Cell-Free Regenerative Endodontics: Clarification of Concept and Term
CE Hours: 1.25
Description: This presentation will clarify the concept of regenerative endodontics and review its progress. There are two categories of clinical approaches to regain vitalization of pulp. One is stem-cell based therapy that involves implanting exogenously processed stem cells into the root canal space, termed cell-based regenerative endodontic therapy (CB-RET). This approach has shown the regeneration of pulp- and dentin-like tissues in the canal space from animal and human clinical trial studies, suggesting potential practice of true “regenerative endodontics” in the future. On the other hand, revitalization or also termed revascularization, that does not involve the delivery of exogenously processed stem cells into the canals therefore is termed cell-free regenerative endodontic therapy (CF-RET). The various animal and human clinical studies have shown that the tissues developed in CF-RETs are fibrous connective tissue, some resembling periodontal ligament, not pulp-like, and the mineral tissue as cementum-like or bone, not dentin-like. One outcome regarding revitalization treatment is canal space obliteration by calcification which accounts for a high percentage of such cases.
- Describe the definitions of CB-RET and CF-RET.
- Describe the progress of CB-RET.
- Describe the progress of CF-RET.
