Next-Gen Dental Therapies: Bridging Bioengineering with Pharmacological Science

Regenerative dentistry has emerged as a critical paradigm shift in oral healthcare, moving beyond symptom management to true biological reconstruction. Effective oral tissue restoration demands a shift from conventional reparative treatments to regenerative strategies capable of rebuilding complex biological structures. This review synthesizes advancements in regenerative dentistry, focusing on the synergistic interplay between bioengineering and pharmacology. Central to these next-generation therapies are dental stem cells (e.g., DPSCs, PDLSCs), bioactive signaling molecules like growth factors (BMPs, FGF-2, PDGF), and autologous blood-derived biomaterials such as Platelet-Rich Plasma (PRP) and Platelet-Rich Fibrin (PRF). These approaches leverage advanced scaffolds and delivery systems to create biomimetic microenvironments that guide cellular differentiation, angiogenesis, and matrix synthesis for dentin-pulp, periodontal, and alveolar bone regeneration. Notably, PRF provides a sustained-release, three-dimensional fibrin scaffold enriched with leukocytes and growth factors, offering enhanced therapeutic longevity and immunomodulatory benefits over earlier concentrates. Emerging tools such as nanotechnology and 3D bioprinting further expand the potential of these therapies by enabling precise, patient-specific scaffold fabrication and controlled delivery of bioactive molecules. Despite their transformative potential, significant hurdles, including a lack of protocol standardization, high costs, regulatory complexities, and variability in clinical outcomes, impede widespread adoption. Future progress requires refining biomaterials through innovations like 3D bioprinting, establishing evidence-based clinical protocols through rigorous trials, and developing scalable, off-the-shelf solutions. By integrating these advancements into mainstream dentistry, clinicians can offer patients more predictable, biologically harmonious treatments that restore both function and aesthetics while reducing long-term complications.
