The Use of Stem Cells in Dental Regeneration Potential and Challenges
Main Article Content
Abstract
Dental regeneration using stem cell-based therapies represents a groundbreaking approach to addressing dental tissue loss caused by caries, trauma, and congenital defects. Unlike conventional treatments that focus on symptom management, stem cell therapies aim to restore structure and function through biological regeneration. Stem cells, including dental pulp stem cells (DPSCs), periodontal ligament stem cells (PDLSCs), and stem cells from human exfoliated deciduous teeth (SHED), have demonstrated remarkable potential to differentiate into odontoblasts, osteoblasts, and other specialized cells necessary for dental tissue repair.
Significant advancements in tissue engineering, biomaterials, and bioactive molecule delivery have facilitated the development of scaffolds that support stem cell proliferation and differentiation, enhancing regenerative outcomes. Clinical applications include dentin-pulp regeneration, periodontal repair, alveolar bone augmentation, and root bioengineering. Emerging technologies, such as 3D printing, gene therapy, and low-level laser therapy, are further improving precision and efficiency in dental regeneration.
This paper examines the biological mechanisms, clinical applications, and advancements in stem cell-based dental regeneration while addressing the key challenges that must be overcome. By advancing research, improving regulatory frameworks, and fostering interdisciplinary collaboration, stem cell therapies hold the potential to transform regenerative dentistry and improve patient outcomes.
