Pulpal and blood extracellular proteins

Pulpal and blood extracellular proteins at the pulpotomy site refer to the complex mixture of proteins, including albumin, globulins, fibrinogen, and various growth factors, that are present in the dental pulp tissue and blood during a pulpotomy procedure [StatPearls, 2023]. These proteins are not a single therapeutic target but rather a biological environment that interacts with dental materials to facilitate healing or tissue fixation. For instance, calcium silicate-based materials like Mineral Trioxide Aggregate (MTA) interact with these proteins and tissue fluids to form a hydroxyapatite-like layer, which promotes the recruitment of odontoblast-like cells and the formation of a protective dentin bridge [Journal of Endodontics, 2015]. Conversely, traditional medicaments such as formocresol act by denaturing and fixating these proteins to devitalize the tissue and prevent bacterial colonization [PubMed, 2020]. Other agents like ferric sulfate interact with blood proteins to form a protein-metal complex that plugs severed blood vessels, achieving hemostasis [American Academy of Pediatric Dentistry, 2022]. Because this term describes a heterogeneous collection of molecules and a physiological site rather than a specific receptor or enzyme, it is classified as an incorrect or non-specific therapeutic target for drug discovery purposes.

Medicaments interact with these proteins through chemical fixation (denaturation), coagulation to achieve hemostasis, or by providing a scaffold for the induction of mineralization and dentin bridge formation.
