Dental pulp tissue proteins and extracellular matrix

The dental pulp tissue proteins and extracellular matrix (ECM) constitute the specialized biological environment within the tooth's central chamber, providing both structural support and a reservoir for signaling molecules. The ECM is primarily composed of fibrous proteins like Type I and Type III collagen, alongside non-collagenous proteins such as dentin sialophosphoprotein (DSPP) and dentin matrix protein 1 (DMP1) that are critical for dentin mineralization (Source: PubMed, PMID: 25703244). This matrix also sequesters essential growth factors, including transforming growth factor-beta (TGF-β) and bone morphogenetic proteins (BMPs), which are released during injury to facilitate tissue repair and regeneration (Source: UniProt, P36222). In clinical endodontics, materials like Mineral Trioxide Aggregate (MTA) and calcium hydroxide are applied to interact with this matrix, inducing the formation of a reparative dentin bridge (Source: StatPearls, NBK532263). While not a single molecular target, the dental pulp ECM is the focus of regenerative therapies aimed at maintaining tooth vitality and treating conditions like pulpitis. Understanding the pulpal proteome is essential for advancing tissue engineering strategies in restorative dentistry (Source: PMC, PMC4293706).
