Deep Margin Elevation With Various Resin Composites: Effect of Thermomechanical Aging on the Marginal Gap of CAD/CAM Inlays

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This in vitro study evaluated the effects of composite material type, margin design (deep margin elevation vs. control), and thermomechanical aging on the marginal gap of CAD/CAM inlay restorations. Materials and Methods Standardized mesio‐occluso‐distal (MOD) inlay cavities were prepared in extracted human molars, with mesial ...

Harnessing the Therapeutic Potential of Cell Secretomes and Extracellular Vesicles for Craniofacial Regenerative Applications

Journal of Periodontal Research, EarlyView.
The scoping review summarizes the current preclinical and clinical evidence for the use of “cell‐free” therapies in craniofacial (periodontal, bone and soft‐tissue) regeneration. It also aims to highlight key challenges and strategies towards the clinical translation of these therapies.

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 ...
