Electrical Stimulation of Oral Tissue-Derived Stem Cells: Unlocking New Potential for Dental and Periodontal Regeneration.

The tooth and its supporting periodontium are essential structures of the oral cavity, frequently compromised by conditions such as dental defects, aries, and periodontal diseases, which, if poorly treated, often lead to tooth loss. These conditions, affecting billions of people worldwide, remain significant healthcare and socio-economic challenges. Regenerative dentistry has emerged as a possible therapeutic option, leveraging advances in tissue engineering (TE), stem cell biology, and biophysical stimulation. Oral tissue-derived mesenchymal stem/stromal cells (OMSCs) hold great potential for dental and periodontal regeneration. Electrical stimulation (ES), a biophysical cue known to regulate key cellular behaviors such as migration, proliferation, and differentiation, has gained increasing attention for enhancing the therapeutic capacities of OMSCs. This review explores the biological properties of OMSCs under ES, its role in regenerative dentistry, and recent breakthroughs in ES-based dental and periodontal TE strategies. Furthermore, the current challenges and future directions for translating these innovative approaches into clinical practice are discussed.
