Dental pulp proteins and enzymes

Dental pulp proteins and enzymes represent the collective proteomic and enzymatic profile of the dental pulp, a specialized connective tissue responsible for tooth vitality and dentin formation (StatPearls, 2024). This group includes structural proteins such as Type I collagen and dentin sialophosphoprotein (DSPP), which are critical for the mineralization of reparative dentin (J. Clin. Pediatr. Dent., 2015). Enzymes like matrix metalloproteinases (MMPs) and alkaline phosphatase (ALP) play dual roles in extracellular matrix remodeling and the initiation of calcification (Eur. J. Oral Sci., 2003). In the context of disease, inflammatory mediators like TNF-α and IL-6 serve as biomarkers for pulpitis, while the dysregulation of MMPs can lead to irreversible tissue destruction (NIH, 2023). Therapeutic interventions often target specific members of this group; for instance, GSK3 inhibitors like Tideglusib are used to stimulate the Wnt/β-catenin pathway for natural dentin repair (MDPI, 2023). Additionally, HDAC inhibitors are explored for their ability to enhance the regenerative potential of dental pulp stem cells by modifying epigenetic states (NIH, 2023). Bioactive materials such as Mineral Trioxide Aggregate (MTA) also interact with these proteins to promote healing and mineral barrier formation (J. Endod., 2022). Overall, these molecules are essential for maintaining dental homeostasis and are the primary focus of regenerative endodontic research.

Mechanisms include the inhibition of Glycogen Synthase Kinase 3 (GSK3) to activate Wnt/beta-catenin signaling for dentin repair, the inhibition of Histone Deacetylases (HDACs) to promote odontogenic differentiation, and the inhibition of Cyclooxygenase (COX) enzymes to manage pulpal inflammation and pain.
