Cell Therapy for Periodontal, Soft‐Tissue, and Craniofacial Regeneration

Journal of Periodontal Research, EarlyView.
The clinical translation of mesenchymal stem/stromal cells (MSCs) represents a major advancement in dentistry, especially for periodontal, soft‐tissue, and craniofacial regeneration. However, several challenges remain to be addressed, including the absence of standardised protocols, limited scalability, regulatory hurdles, a lack of well‐controlled ...

Herpesvirus Simplex Virus‐1 Exploits Inflammation to Infect Periodontal Stem Cells and Disrupt Lineage Commitment

Journal of Periodontal Research, EarlyView.
HSV‐1 infects oral mesenchymal stem cells both in vitro and in vivo to dysregulate their lineage commitment. An inflamed gingival environment increases susceptibility to HSV‐1 infection, which further elevates proinflammatory cytokine levels and exacerbates alveolar bone loss.

Soft Tissue Substitutes: Current Biomaterials and Indications at Teeth and Implant Sites

Journal of Periodontal Research, EarlyView.
This manuscript provides an updated overview of the current evidence on soft tissue graft substitutes for teeth and dental implants. When appropriately indicated, these biomaterials offer a reliable, less invasive alternative to autogenous grafts, effectively improving root coverage, keratinized mucosa width, and soft tissue thickness with reduced ...
