Dental pulp stem cells represent a remarkable frontier in the field of regenerative dentistry, offering unprecedented opportunities to restore damaged tissues and improve oral health outcomes. These specialized stem cells reside within the dental pulp, a highly vascularized and innervated connective tissue found in the centre of the tooth. Beyond their role in dentin formation and pulp homeostasis, dental pulp stem cells possess multipotent capabilities, enabling them to differentiate into a variety of cell types including odontoblasts, osteoblasts, chondrocytes and even neural cells [1]. Harnessing their regenerative potential holds promise not only for dental tissue repair but also for systemic therapeutic applications, positioning these cells at the intersection of basic science, clinical dentistry and translational medicine.
The dental pulp serves as a reservoir for stem cells that maintain tissue integrity and mediate repair following injury or disease. These cells exhibit self-renewal capacity, which allows them to generate progenitor cells while preserving their undifferentiated state. In addition to their proliferative ability, dental pulp stem cells secrete a range of bioactive molecules that influence angiogenesis, immunomodulation and extracellular matrix formation. This combination of intrinsic differentiation potential and paracrine signaling renders them ideal candidates for regenerative therapies targeting dental and periodontal tissues, as well as craniofacial bone and soft tissue reconstruction.
Isolation and characterization of dental pulp stem cells are critical steps in translating their potential into clinical applications. The cells are typically obtained from extracted teeth, including third molars or deciduous teeth, using enzymatic digestion or explant culture techniques [2-4]. Once isolated, stem cells are characterized by their surface marker expression, proliferative capacity and differentiation potential. Advanced techniques such as flow cytometry, immunocytochemistry and gene expression analysis allow researchers to confirm stemness and identify subpopulations with specific regenerative capabilities. Standardizing these protocols ensures reproducibility, safety and efficacy in clinical applications.
The multipotent nature of dental pulp stem cells allows them to contribute to a broad spectrum of regenerative processes. When differentiated into odontoblast like cells, they can deposit dentin and contribute to the repair of pulp injuries or carious lesions [5]. Osteogenic differentiation supports alveolar bone regeneration, which is valuable in periodontal therapy and implant site preparation. Chondrogenic differentiation offers potential for temporomandibular joint repair, while neurogenic differentiation enables the exploration of craniofacial nerve regeneration. This versatility underscores the value of dental pulp stem cells as a cornerstone of tissue engineering strategies in dentistry.
Scaffolds play a crucial role in guiding the regenerative potential of dental pulp stem cells. Biocompatible materials such as collagen, hydroxyapatite, synthetic polymers, or decellularized extracellular matrices provide a three-dimensional structure that supports cell adhesion, proliferation, and differentiation. Incorporating growth factors, cytokines, or signaling molecules into scaffolds further enhances tissue regeneration by promoting angiogenesis, chemotaxis and cellular maturation. The combination of stem cells and tailored scaffolds allows for precise tissue engineering, enabling the reconstruction of complex dental and craniofacial defects.
Dental pulp stem cells also exhibit significant immunomodulatory properties, which are critical for ensuring a favorable regenerative microenvironment [6,7]. They can suppress pro-inflammatory responses, modulate T-cell activity and secrete anti-inflammatory cytokines, reducing tissue damage and enhancing healing outcomes. This capacity not only benefits local tissue repair but also supports the potential for systemic applications in immune-mediated conditions, neurodegenerative diseases and cardiovascular disorders. By modulating inflammation and promoting regeneration simultaneously, dental pulp stem cells exemplify the convergence of biological therapy and clinical dentistry.
Regenerative endodontics has emerged as a prime clinical application of dental pulp stem cells. In immature teeth with necrotic pulp, conventional treatment often results in arrested root development and thin dentinal walls, increasing fracture risk [8]. By introducing stem cells into disinfected root canals, clinicians can stimulate the formation of new pulp-like tissue, promote continued root development and restore vitality. Clinical protocols typically involve careful canal disinfection, scaffold placement and induction of bleeding to provide a natural cell-rich matrix. Follow-up evaluation over months and years allows monitoring of root growth, tissue formation and functional recovery.
Despite their potential, challenges remain in translating dental pulp stem cells from research to routine clinical practice. Variability in donor tissue, limited cell numbers, and the risk of microbial contamination can affect therapeutic outcomes. Ensuring cell survival, directing appropriate differentiation and achieving vascularization within engineered tissues remain critical hurdles. Additionally, regulatory frameworks governing stem cell therapies require stringent quality control, safety validation and ethical considerations [9,10]. Ongoing research aims to address these challenges through improved cell expansion techniques, gene editing, bioreactor systems and scaffold optimization.
Dental pulp stem cells offer extraordinary opportunities to advance regenerative dentistry and beyond. Their multipotency, self-renewal capacity and immunomodulatory properties make them ideal candidates for tissue engineering and clinical applications targeting pulp, periodontal and craniofacial tissues. Through the use of scaffolds, growth factors and precise clinical protocols, dental pulp stem cells can restore tissue function, promote healing and preserve oral health.
