Abstract
Tissue regeneration is the procedure of renewal, restoration and growth of injured tissues and defective organs including nerve, bone, tooth, cartilage and blood vessels. Repair process of damaged tissues needs non-invasive methods; so, the scientists have recently focused on alternative treatment pathways. Nano gels based on Poly Lactic-co-Glycolic Acid have been designed for different purposes in medicine. It is a biodegradable and biocompatible polymer composite. Also, human dental pulp stem cells embedded in the Poly Lactic-co-Glycolic Acid scaffold have proliferation ability and differentiation potential. They can differentiate into different cell lineages, including bone, cartilage, nerve, tooth and other tissues. So, this treatment technology can be used for tissue engineering in regenerative medicine. On the other hand, this structure is a promising application for targeted cancer therapy. Therefore, this review studied tissue, especially tooth regeneration based on the new designed Nano composite scaffolds embedded with Poly Lactic-co-Glycolic Acid hydrogel and dental pulp stem cells.
